Spirng+SpringMVC+Maven+Mybatis+MySQL项目搭建

jopen 6年前

这篇文章主要讲解使用eclipse对Spirng+SpringMVC+Maven+Mybatis+MySQL项目搭建过程,包括里面步骤和里面的配置文件如何配置等等都会详细说明。

如果还没有搭建好环境(主要是Maven+MySQL的配置)的猿友可以参考博主以前的一篇文章:
http://blog.csdn.net/u013142781/article/details/50300233

接下来马上进入项目搭建过程:

1、创建表,并插入数据:

CREATE TABLE `t_user` ( `USER_ID` int(11) NOT NULL AUTO_INCREMENT, `USER_NAME` char(30) NOT NULL, `USER_PASSWORD` char(10) NOT NULL, PRIMARY KEY (`USER_ID`), KEY `IDX_NAME` (`USER_NAME`) ) ENGINE=InnoDB AUTO_INCREMENT=11 DEFAULT CHARSET=utf8
INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD) VALUES (1, 'luoguohui', '123456');  INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD) VALUES (2, 'zhangsan', '123456');

2、Maven工程创建

3、选择快速框架

4、输出项目名,包(Packaging,如果只是普通的项目,选jar就好了,如果是web项目就选war,这里是web项目,所以选择war)

这里写图片描述

5、创建好的目录如下:

6、添加包的依赖,编辑pom.xml文件添加如下依赖:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">    <modelVersion>4.0.0</modelVersion>    <groupId>com.luo</groupId>    <artifactId>first_maven_project</artifactId>    <version>0.0.1-SNAPSHOT</version>    <packaging>war</packaging>      <properties>          <!-- spring版本号 -->          <spring.version>3.2.8.RELEASE</spring.version>          <!-- log4j日志文件管理包版本 -->          <slf4j.version>1.6.6</slf4j.version>          <log4j.version>1.2.12</log4j.version>          <!-- junit版本号 -->          <junit.version>4.10</junit.version>          <!-- mybatis版本号 -->          <mybatis.version>3.2.1</mybatis.version>    </properties>      <dependencies>          <!-- 添加Spring依赖 -->          <dependency>              <groupId>org.springframework</groupId>              <artifactId>spring-core</artifactId>              <version>${spring.version}</version>          </dependency>          <dependency>              <groupId>org.springframework</groupId>              <artifactId>spring-webmvc</artifactId>              <version>${spring.version}</version>          </dependency>          <dependency>              <groupId>org.springframework</groupId>              <artifactId>spring-context</artifactId>              <version>${spring.version}</version>          </dependency>          <dependency>              <groupId>org.springframework</groupId>              <artifactId>spring-context-support</artifactId>              <version>${spring.version}</version>          </dependency>          <dependency>              <groupId>org.springframework</groupId>              <artifactId>spring-aop</artifactId>              <version>${spring.version}</version>          </dependency>          <dependency>              <groupId>org.springframework</groupId>              <artifactId>spring-aspects</artifactId>              <version>${spring.version}</version>          </dependency>          <dependency>              <groupId>org.springframework</groupId>              <artifactId>spring-tx</artifactId>              <version>${spring.version}</version>          </dependency>          <dependency>              <groupId>org.springframework</groupId>              <artifactId>spring-jdbc</artifactId>              <version>${spring.version}</version>          </dependency>          <dependency>              <groupId>org.springframework</groupId>              <artifactId>spring-web</artifactId>              <version>${spring.version}</version>          </dependency>            <!--单元测试依赖 -->          <dependency>              <groupId>junit</groupId>              <artifactId>junit</artifactId>              <version>${junit.version}</version>              <scope>test</scope>          </dependency>            <!-- 日志文件管理包 -->          <!-- log start -->          <dependency>              <groupId>log4j</groupId>              <artifactId>log4j</artifactId>              <version>${log4j.version}</version>          </dependency>          <dependency>              <groupId>org.slf4j</groupId>              <artifactId>slf4j-api</artifactId>              <version>${slf4j.version}</version>          </dependency>          <dependency>              <groupId>org.slf4j</groupId>              <artifactId>slf4j-log4j12</artifactId>              <version>${slf4j.version}</version>          </dependency>          <!-- log end -->            <!--spring单元测试依赖 -->          <dependency>              <groupId>org.springframework</groupId>              <artifactId>spring-test</artifactId>              <version>${spring.version}</version>              <scope>test</scope>          </dependency>            <!--mybatis依赖 -->          <dependency>              <groupId>org.mybatis</groupId>              <artifactId>mybatis</artifactId>              <version>${mybatis.version}</version>          </dependency>            <!-- mybatis/spring包 -->          <dependency>              <groupId>org.mybatis</groupId>              <artifactId>mybatis-spring</artifactId>              <version>1.2.0</version>          </dependency>            <!-- mysql驱动包 -->          <dependency>              <groupId>mysql</groupId>              <artifactId>mysql-connector-java</artifactId>              <version>5.1.29</version>          </dependency>      </dependencies>    </project>

7、配置文件:

这里写图片描述

7.1、mybatis包下添加mybatis-config.xml文件(mybatis配置文件):

<?xml version="1.0" encoding="UTF-8"?>    <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd">    <configuration>      </configuration>

7.2、properties包下添加jdbc.properties文件(数据源配置文件):

jdbc_driverClassName=com.mysql.jdbc.Driver  jdbc_url=jdbc:mysql://localhost:3306/luo  jdbc_username=root  jdbc_password=root

7.3、mapper包下userMapper.xml配置文件(表映射文件):

<?xml version="1.0" encoding="UTF-8"?>    <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">  <mapper namespace="com.luo.dao.UserDao">  <!--设置domain类和数据库中表的字段一一对应,注意数据库字段和domain类中的字段名称不致,此处一定要!-->      <resultMap id="BaseResultMap" type="com.luo.domain.User">          <id column="USER_ID" property="userId" jdbcType="INTEGER" />          <result column="USER_NAME" property="userName" jdbcType="CHAR" />          <result column="USER_PASSWORD" property="userPassword" jdbcType="CHAR" />      </resultMap>      <!-- 查询单条记录 -->      <select id="selectUserById" parameterType="int" resultMap="BaseResultMap">          SELECT * FROM t_user WHERE USER_ID = #{userId}      </select>  </mapper>

7.4、spring配置文件application.xml:

<?xml version="1.0" encoding="UTF-8"?>  <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd">         <!-- 引入jdbc配置文件 -->         <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">          <property name="locations">              <list>                 <value>classpath:properties/*.properties</value>                  <!--要是有多个配置文件,只需在这里继续添加即可 -->              </list>          </property>      </bean>            <!-- 配置数据源 -->      <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">          <!-- 不使用properties来配置 -->          <!-- <property name="driverClassName" value="com.mysql.jdbc.Driver" /> <property name="url" value="jdbc:mysql://localhost:3306/learning" /> <property name="username" value="root" /> <property name="password" value="christmas258@" /> -->         <!-- 使用properties来配置 -->          <property name="driverClassName">              <value>${jdbc_driverClassName}</value>          </property>          <property name="url">              <value>${jdbc_url}</value>          </property>          <property name="username">              <value>${jdbc_username}</value>          </property>          <property name="password">              <value>${jdbc_password}</value>          </property>      </bean>        <!-- 自动扫描了所有的XxxxMapper.xml对应的mapper接口文件,这样就不用一个一个手动配置Mpper的映射了,只要Mapper接口类和Mapper映射文件对应起来就可以了。 -->      <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">          <property name="basePackage" value="com.luo.dao" />      </bean>        <!-- 配置Mybatis的文件 ,mapperLocations配置**Mapper.xml文件位置,configLocation配置mybatis-config文件位置-->      <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">          <property name="dataSource" ref="dataSource" />          <property name="mapperLocations" value="classpath:mapper/*.xml"/>            <property name="configLocation" value="classpath:mybatis/mybatis-config.xml" />          <!-- <property name="typeAliasesPackage" value="com.tiantian.ckeditor.model" /> -->      </bean>        <!-- 自动扫描注解的bean -->      <context:component-scan base-package="com.luo.service" />    </beans>

8、接口和类的配置:

这里写图片描述

8.1、com.luo.domain下添加User.java文件:

package com.luo.domain;    public class User {        private Integer userId;        private String userName;        private String userPassword;            public Integer getUserId() {            return userId;        }          public void setUserId(Integer userId) {            this.userId = userId;        }          public String getUserName() {            return userName;        }          public void setUserName(String userName) {            this.userName = userName;        }          public String getUserPassword() {            return userPassword;        }          public void setUserPassword(String userPassword) {            this.userPassword = userPassword;        }      }

8.2、com.luo.dao下添加UserDao.java文件:

package com.luo.dao;    import com.luo.domain.User;    public interface UserDao {        /** * @param userId * @return User */      public User selectUserById(Integer userId);      }

8.3、com.luo.service下添加UserService.java接口和UserServiceImpl实现类:

package com.luo.service;    import com.luo.domain.User;    public interface UserService {      User selectUserById(Integer userId);   }
package com.luo.service;    import org.springframework.beans.factory.annotation.Autowired;  import org.springframework.stereotype.Service;  import com.luo.dao.UserDao;  import com.luo.domain.User;    @Service    public class UserServiceImpl implements UserService {        @Autowired        private UserDao userDao;          public User selectUserById(Integer userId) {            return userDao.selectUserById(userId);          }    }

9、单元测试

这里写图片描述

9.1、com.luo.baseTest下添加SpringTestCase.java:

package com.luo.baseTest;    import org.junit.runner.RunWith;    import org.springframework.test.context.ContextConfiguration;    import org.springframework.test.context.junit4.AbstractJUnit4SpringContextTests;    import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;      //指定bean注入的配置文件   @ContextConfiguration(locations = { "classpath:application.xml" })    //使用标准的JUnit @RunWith注释来告诉JUnit使用Spring TestRunner   @RunWith(SpringJUnit4ClassRunner.class)    public class SpringTestCase extends AbstractJUnit4SpringContextTests {    }

9.2、com.luo.service添加UserServiceTest.java:

package com.luo.service;    import org.junit.Test;    import org.springframework.beans.factory.annotation.Autowired;    import com.luo.baseTest.SpringTestCase;    import com.luo.domain.User;    public class UserServiceTest extends SpringTestCase {        @Autowired        private UserService userService;         @Test        public void selectUserByIdTest(){            User user = userService.selectUserById(1);            System.out.println(user.getUserName() + ":" + user.getUserPassword());      }    }

9.3、运行单元测试,UserServiceTest右键Run As –>Junit Test,运行结果:

这里写图片描述


下面加入springmvc,并转换maven工程为web项目


10、转换成web项目:

如果上面webapp为空的,说明这个项目还不是web项目:

这里写图片描述

接下来打开如下页面。将红框里面的勾去掉,确定(OK):

这里写图片描述

然后重新打开刚刚那个页面,把Dynamic web Module勾上,就会看到红框的内容,点击:

这里写图片描述

然后配置如下:

这里写图片描述

那么webapp下就会生成这些东西:

这里写图片描述

11、配置springmvc

11.1、pom.xml文件添加依赖,修改后配置如下:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">    <modelVersion>4.0.0</modelVersion>    <groupId>com.luo</groupId>    <artifactId>first_maven_project</artifactId>    <version>0.0.1-SNAPSHOT</version>    <packaging>war</packaging>      <properties>          <!-- spring版本号 -->          <spring.version>3.2.8.RELEASE</spring.version>          <!-- junit版本号 -->          <junit.version>4.10</junit.version>          <!-- mybatis版本号 -->          <mybatis.version>3.2.1</mybatis.version>    </properties>      <dependencies>          <!-- 添加Spring依赖 -->          <dependency>              <groupId>org.springframework</groupId>              <artifactId>spring-core</artifactId>              <version>${spring.version}</version>          </dependency>          <dependency>              <groupId>org.springframework</groupId>              <artifactId>spring-webmvc</artifactId>              <version>${spring.version}</version>          </dependency>          <dependency>              <groupId>org.springframework</groupId>              <artifactId>spring-context</artifactId>              <version>${spring.version}</version>          </dependency>          <dependency>              <groupId>org.springframework</groupId>              <artifactId>spring-context-support</artifactId>              <version>${spring.version}</version>          </dependency>          <dependency>              <groupId>org.springframework</groupId>              <artifactId>spring-aop</artifactId>              <version>${spring.version}</version>          </dependency>          <dependency>              <groupId>org.springframework</groupId>              <artifactId>spring-aspects</artifactId>              <version>${spring.version}</version>          </dependency>          <dependency>              <groupId>org.springframework</groupId>              <artifactId>spring-tx</artifactId>              <version>${spring.version}</version>          </dependency>          <dependency>              <groupId>org.springframework</groupId>              <artifactId>spring-jdbc</artifactId>              <version>${spring.version}</version>          </dependency>          <dependency>              <groupId>org.springframework</groupId>              <artifactId>spring-web</artifactId>              <version>${spring.version}</version>          </dependency>            <!--单元测试依赖 -->          <dependency>              <groupId>junit</groupId>              <artifactId>junit</artifactId>              <version>${junit.version}</version>              <scope>test</scope>          </dependency>            <!--spring单元测试依赖 -->          <dependency>              <groupId>org.springframework</groupId>              <artifactId>spring-test</artifactId>              <version>${spring.version}</version>              <scope>test</scope>          </dependency>            <!--mybatis依赖 -->          <dependency>              <groupId>org.mybatis</groupId>              <artifactId>mybatis</artifactId>              <version>${mybatis.version}</version>          </dependency>            <!-- mybatis/spring包 -->          <dependency>              <groupId>org.mybatis</groupId>              <artifactId>mybatis-spring</artifactId>              <version>1.2.0</version>          </dependency>            <!-- mysql驱动包 -->          <dependency>              <groupId>mysql</groupId>              <artifactId>mysql-connector-java</artifactId>              <version>5.1.29</version>          </dependency>            <!-- javaee-api包 注意和项目使用的JDK版本对应 -->            <dependency>                <groupId>javax</groupId>                <artifactId>javaee-api</artifactId>                <version>6.0</version>                <scope>provided</scope>            </dependency>              <!-- javaee-web-api包 注意和项目使用的JDK版本对应 -->            <dependency>                <groupId>javax</groupId>                <artifactId>javaee-web-api</artifactId>                <version>6.0</version>                <scope>provided</scope>            </dependency>          </dependencies>    </project>

其实也就增加了下面两个

<!-- javaee-api包 注意和项目使用的JDK版本对应 -->  <dependency>      <groupId>javax</groupId>      <artifactId>javaee-api</artifactId>      <version>6.0</version>      <scope>provided</scope>  </dependency>    <!-- javaee-web-api包 注意和项目使用的JDK版本对应 -->  <dependency>      <groupId>javax</groupId>      <artifactId>javaee-web-api</artifactId>      <version>6.0</version>      <scope>provided</scope>  </dependency>

11.2、在src/main/resource中添加springmvc文件夹,然后添加文件spring-mvc.xml,内容如下:

11.3、配置web.xml

<?xml version="1.0" encoding="UTF-8"?>  <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">      <display-name>Archetype Created Web Application</display-name>     <!-- 起始欢迎界面 -->      <welcome-file-list>          <welcome-file>index.jsp</welcome-file>      </welcome-file-list>        <!-- 读取spring配置文件 -->      <context-param>          <param-name>contextConfigLocation</param-name>          <param-value>classpath:application.xml</param-value>      </context-param>      <!-- 设计路径变量值 -->      <context-param>          <param-name>webAppRootKey</param-name>          <param-value>springmvc.root</param-value>      </context-param>          <!-- Spring字符集过滤器 -->      <filter>          <filter-name>SpringEncodingFilter</filter-name>          <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>          <init-param>              <param-name>encoding</param-name>              <param-value>UTF-8</param-value>          </init-param>          <init-param>              <param-name>forceEncoding</param-name>              <param-value>true</param-value>          </init-param>      </filter>      <filter-mapping>          <filter-name>SpringEncodingFilter</filter-name>          <url-pattern>/*</url-pattern>      </filter-mapping>        <listener>          <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>      </listener>        <!-- springMVC核心配置 -->      <servlet>          <servlet-name>dispatcherServlet</servlet-name>          <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>          <init-param>              <param-name>contextConfigLocation</param-name>              <!--spingMVC的配置路径 -->              <param-value>classpath:springmvc/spring-mvc.xml</param-value>          </init-param>          <load-on-startup>1</load-on-startup>      </servlet>      <!-- 拦截设置 -->      <servlet-mapping>          <servlet-name>dispatcherServlet</servlet-name>          <url-pattern>/</url-pattern>      </servlet-mapping>        <!-- 错误跳转页面 -->      <error-page>          <!-- 路径不正确 -->          <error-code>404</error-code>          <location>/WEB-INF/errorpage/404.jsp</location>      </error-page>      <error-page>          <!-- 没有访问权限,访问被禁止 -->          <error-code>405</error-code>          <location>/WEB-INF/errorpage/405.jsp</location>      </error-page>      <error-page>          <!-- 内部错误 -->          <error-code>500</error-code>          <location>/WEB-INF/errorpage/500.jsp</location>      </error-page>  </web-app>

11.4、添加index.jsp,在src/main/webapp/WEB-INF下新建一个文件夹view,添加一个index.jsp,内容如下:

这里写图片描述

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>  <html>  <body>  <h2>Hello World!</h2>  用户名: ${user.userName}<br>   密码:${user.userPassword}<br>  </body>  </html>

11.5、写controller

这里写图片描述

在src/main/java下新建一个包com.luo.controller.然后新建一个类UserController.java,其内容如下

package com.luo.controller;    import javax.annotation.Resource;  import org.springframework.stereotype.Controller;  import org.springframework.web.bind.annotation.RequestMapping;  import org.springframework.web.servlet.ModelAndView;  import com.luo.domain.User;  import com.luo.service.UserService;    @Controller    public class UserController {          @Resource        private UserService userService;         @RequestMapping("/")          public ModelAndView getIndex(){                ModelAndView mav = new ModelAndView("index");           User user = userService.selectUserById(1);           mav.addObject("user", user);           return mav;       }      }  

11.6 运行!!!!完成!
