springMVC+mybatis框架搭建

首先我们先要弄清搭建项目的一般流程,需要注意哪些方面,想要什么样的效果,自己的功能有哪些?

(假设效果:项目目录结构清晰,能够查询到本地数据库中的内容。。)

1.  工程目录结构整理清楚

在src/main/java文件夹中,新建包cn.springmvc.model(存放javabean),

                                            cn.springmvc.dao(存放spring与mybatis连接接口),

                                            cn.springmvc.service(service接口),

                                            cn.springmvc.service.impl(service接口的实现),

                                            cn.springmvc.controller(存放控制层controller)

在src/main/resource文件夹中,新建包conf(存放配置文件),

                                                   mapper(mybatis的mapper文件)

在src/test/java文件夹中,新建包cn.springmvc.test(存放测试文件)

在WEB-INF文件夹下新建jsp文件夹(存放jsp文件)

这样项目结构基本完成了

2.  引入依赖包

打开maven的pom文件,对本次开发所需使用的架包依次导入(maven项目管理的优势)

查找依赖结构有个不错的网站,http://search.maven.org/   只要输入包名即可查找引来关系

pom.xml(包依赖)


<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/maven-v4_0_0.xsd">   <modelVersion>4.0.0</modelVersion>   <groupId>eyas.springmvc</groupId>   <artifactId>springmvc</artifactId>   <packaging>war</packaging>   <version>0.0.1-SNAPSHOT</version>   <name>springmvc Maven Webapp</name>   <url>http://maven.apache.org</url>   <properties>    <!-- spring版本号 -->    <spring.version>3.2.4.RELEASE</spring.version>    <!-- mybatis版本号 -->    <mybatis.version>3.2.4</mybatis.version>    <!-- log4j日志文件管理包版本 -->    <slf4j.version>1.6.6</slf4j.version>    <log4j.version>1.2.9</log4j.version>   </properties>   <dependencies>    <!-- spring核心包 -->    <!-- springframe start -->    <dependency>     <groupId>org.springframework</groupId>     <artifactId>spring-core</artifactId>     <version>${spring.version}</version>    </dependency>      <dependency>     <groupId>org.springframework</groupId>     <artifactId>spring-web</artifactId>     <version>${spring.version}</version>    </dependency>      <dependency>     <groupId>org.springframework</groupId>     <artifactId>spring-oxm</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>${spring.version}</version>    </dependency>      <dependency>     <groupId>org.springframework</groupId>     <artifactId>spring-webmvc</artifactId>     <version>${spring.version}</version>    </dependency>      <dependency>     <groupId>org.springframework</groupId>     <artifactId>spring-aop</artifactId>     <version>${spring.version}</version>    </dependency>      <dependency>     <groupId>org.springframework</groupId>     <artifactId>spring-context-support</artifactId>     <version>${spring.version}</version>    </dependency>      <dependency>     <groupId>org.springframework</groupId>     <artifactId>spring-aop</artifactId>     <version>${spring.version}</version>    </dependency>      <dependency>     <groupId>org.springframework</groupId>     <artifactId>spring-test</artifactId>     <version>${spring.version}</version>    </dependency>    <!-- springframe end -->      <!-- mybatis核心包 -->    <dependency>     <groupId>org.mybatis</groupId>     <artifactId>mybatis</artifactId>     <version>${mybatis.version}</version>    </dependency>    <!-- mybatis/spring包 -->    <dependency>     <groupId>org.mybatis</groupId>     <artifactId>mybatis-spring</artifactId>     <version>1.2.2</version>    </dependency>    <!-- mysql驱动包 -->    <dependency>     <groupId>mysql</groupId>     <artifactId>mysql-connector-java</artifactId>     <version>5.1.29</version>    </dependency>    <!-- junit测试包 -->    <dependency>     <groupId>junit</groupId>     <artifactId>junit</artifactId>     <version>4.11</version>     <scope>test</scope>    </dependency>    <!-- 阿里巴巴数据源包 -->    <dependency>     <groupId>com.alibaba</groupId>     <artifactId>druid</artifactId>     <version>1.0.2</version>    </dependency>      <!-- json数据 -->    <dependency>     <groupId>org.codehaus.jackson</groupId>     <artifactId>jackson-mapper-asl</artifactId>     <version>1.9.13</version>    </dependency>      <!-- 日志文件管理包 -->    <!-- log start -->    <dependency>     <groupId>log4j</groupId>     <artifactId>log4j</artifactId>     <version>${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 -->   </dependencies>   <build>    <finalName>springmvc</finalName>   </build>  </project>


3. 配置数据库连接属性

conf/ jdbc.properties(jdbc配置文件)

jdbc_driverClassName=com.mysql.jdbc.Driver  jdbc_url=jdbc:mysql://localhost:3306/mydays?useUnicode=true&amp;characterEncoding=utf-8  jdbc_username=root  jdbc_password=root

4.  配置spring配置文件

    conf/spring.xml(spring配置文件的扫描)


<?xml version="1.0" encoding="UTF-8"?>  <beans xmlns="http://www.springframework.org/schema/beans"   xmlns:context="http://www.springframework.org/schema/context"   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"   xsi:schemaLocation="http://www.springframework.org/schema/beans        http://www.springframework.org/schema/beans/spring-beans-3.0.xsd        http://www.springframework.org/schema/context        http://www.springframework.org/schema/context/spring-context.xsd">        <!-- 引入jdbc配置文件 -->      <context:property-placeholder location="classpath:conf/jdbc.properties"/>            <!-- 扫描文件(自动将servicec层注入) -->      <context:component-scan base-package="cn.springmvc.service"/>  </beans>
  conf/spring-mybatis.xml(spring与mybatis连接属性)
<?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:p="http://www.springframework.org/schema/p"    xmlns:context="http://www.springframework.org/schema/context"    xmlns:aop="http://www.springframework.org/schema/aop"    xmlns:tx="http://www.springframework.org/schema/tx"    xmlns:util="http://www.springframework.org/schema/util"    xsi:schemaLocation="http://www.springframework.org/schema/beans      http://www.springframework.org/schema/beans/spring-beans-3.2.xsd      http://www.springframework.org/schema/context      http://www.springframework.org/schema/context/spring-context-3.2.xsd      http://www.springframework.org/schema/tx      http://www.springframework.org/schema/tx/spring-tx-3.2.xsd      http://www.springframework.org/schema/aop      http://www.springframework.org/schema/aop/spring-aop-3.2.xsd      http://www.springframework.org/schema/util       http://www.springframework.org/schema/util/spring-util-3.2.xsd">        <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init"      destroy-method="close" >      <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>      <!-- 连接池最大使用连接数 -->      <property name="maxActive">        <value>20</value>      </property>      <!-- 初始化连接大小 -->      <property name="initialSize">        <value>1</value>      </property>      <!-- 获取连接最大等待时间 -->      <property name="maxWait">        <value>60000</value>      </property>      <!-- 连接池最大空闲 -->      <property name="maxIdle">        <value>20</value>      </property>      <!-- 连接池最小空闲 -->      <property name="minIdle">        <value>3</value>      </property>      <!-- 自动清除无用连接 -->      <property name="removeAbandoned">        <value>true</value>      </property>      <!-- 清除无用连接的等待时间 -->      <property name="removeAbandonedTimeout">        <value>180</value>      </property>      <!-- 连接属性 -->      <property name="connectionProperties">        <value>clientEncoding=UTF-8</value>      </property>    </bean>            <!-- mybatis文件配置,扫描所有mapper文件 -->        <bean id="sqlSessionFactory"            class="org.mybatis.spring.SqlSessionFactoryBean"            p:dataSource-ref="dataSource"            p:configLocation="classpath:conf/mybatis-config.xml"            p:mapperLocations="classpath:mapper/*.xml"/><!-- configLocation为mybatis属性 mapperLocations为所有mapper-->             <!-- spring与mybatis整合配置,扫描所有dao -->   <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"          p:basePackage="cn.springmvc.dao"           p:sqlSessionFactoryBeanName="sqlSessionFactory"/>        <!-- 对数据源进行事务管理 -->    <bean id="transactionManager"           class="org.springframework.jdbc.datasource.DataSourceTransactionManager"          p:dataSource-ref="dataSource"/>  </beans>

5.  java代码编写(model,dao,service层代码)

   cn.springmvc.model/User.java(用户基本信息)


package cn.springmvc.model;      /**   * 用户表   */  public class User {     private int id;   private int state;   private String nickname;   public int getId() {    return id;   }   public void setId(int id) {    this.id = id;   }   public int getState() {    return state;   }   public void setState(int state) {    this.state = state;   }   public String getNickname() {    return nickname;   }   public void setNickname(String nickname) {    this.nickname = nickname;   }  }



cn.springmvc.dao/UserDAO.java(dao操作接口)



package cn.springmvc.dao;    import cn.springmvc.model.User;      public interface UserDAO {     /**    * 添加新用户    * @param user    * @return    */   public int insertUser(User user);        }

cn.springmvc.service/UserService.java(service层接口)


package cn.springmvc.service;    import cn.springmvc.model.User;      public interface UserService {     public int insertUser(User user);  }



cn.springmvc.service.impl/UserServiceImpl.java(service层接口实现)




package cn.springmvc.service.impl;    import org.springframework.beans.factory.annotation.Autowired;  import org.springframework.stereotype.Service;    import cn.springmvc.dao.UserDAO;  import cn.springmvc.model.User;  import cn.springmvc.service.UserService;      @Service  public class UserServiceImpl implements UserService{     @Autowired   private UserDAO userDAO;      @Override   public int insertUser(User user) {    // TODO Auto-generated method stub    return userDAO.insertUser(user);   }    }



6.  mybatis配置


   conf/mybatis-config.xml(mybatis配置的基本文件)


<?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>          <!-- 命名空间 -->      <typeAliases>           <typeAlias alias="User" type="cn.springmvc.model.User"/>       </typeAliases>        <!-- 映射map -->      <mappers>      </mappers>  </configuration>



mapper/UserMapper.xml(mybatis的实现)



<?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="cn.springmvc.dao.UserDAO">                        <insert id="insertUser" parameterType="User" keyProperty="id">               insert into days_user(             state,           nickname)            values            (                   #{state},           #{nickname})           </insert>             </mapper>



这样就完成了基本插入用户的功能!


7.  junit测试插入功能


cn.springmvc.test/UserTest.java(用户测试模块)

package cn.springmvc.test;    import org.junit.Before;  import org.junit.Test;  import org.springframework.context.ApplicationContext;  import org.springframework.context.support.ClassPathXmlApplicationContext;    import cn.springmvc.model.User;  import cn.springmvc.service.UserService;        public class UserTest {    private UserService userService;      @Before   public void before(){                                                                        @SuppressWarnings("resource")    ApplicationContext context = new ClassPathXmlApplicationContext(new String[]{"classpath:conf/spring.xml"      ,"classpath:conf/spring-mybatis.xml"});    userService = (UserService) context.getBean("userServiceImpl");   }      @Test   public void addUser(){    User user = new User();    user.setNickname("你好");    user.setState(2);    System.out.println(userService.insertUser(user));   }  }



测试结果如图:

即完成插入功能!

8.  springMVC模块搭建 

    web.xml(web功能配置)

<?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>     <!-- 读取spring配置文件 -->   <context-param>    <param-name>contextConfigLocation</param-name>    <param-value>classpath:conf/spring.xml;     classpath:conf/spring-mybatis.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>     <!-- 日志记录 -->   <context-param>    <!-- 日志配置文件路径 -->    <param-name>log4jConfigLocation</param-name>    <param-value>classpath:conf/log4j.properties</param-value>   </context-param>   <context-param>    <!-- 日志页面的刷新间隔 -->    <param-name>log4jRefreshInterval</param-name>    <param-value>6000</param-value>   </context-param>   <listener>    <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>   </listener>     <listener>    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>   </listener>     <!-- springMVC核心配置 -->   <servlet>    <servlet-name>spring</servlet-name>    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>    <init-param>     <param-name>contextConfigLocation</param-name>     <param-value>classpath:conf/spring-mvc.xml</param-value>    </init-param>    <load-on-startup>2</load-on-startup>   </servlet>   <servlet-mapping>    <servlet-name>spring</servlet-name>    <url-pattern>*.do</url-pattern>   </servlet-mapping>     <welcome-file-list>    <welcome-file>index.jsp</welcome-file>   </welcome-file-list>     <!-- 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>

9.  log4j日志记录搭建


    conf/log4j.properties(日志记录的配置文件)

 ### set log levels ###  #log4j.rootLogger = debug , stdout , D , E  log4j.rootLogger = debug , stdout , D    ###  output to the console ###  log4j.appender.stdout = org.apache.log4j.ConsoleAppender  log4j.appender.stdout.Target = System.out  log4j.appender.stdout.layout = org.apache.log4j.PatternLayout  #log4j.appender.stdout.layout.ConversionPattern = %d{ABSOLUTE} %5p %c{ 1 }:%L - %m%n  log4j.appender.stdout.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss} [%c]-[%p] %m%n    ### Output to the log file ###  log4j.appender.D = org.apache.log4j.DailyRollingFileAppender  log4j.appender.D.File = ${springmvc.root}/WEB-INF/logs/log.log  log4j.appender.D.Append = true  log4j.appender.D.Threshold = DEBUG   log4j.appender.D.layout = org.apache.log4j.PatternLayout  log4j.appender.D.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss} [ %t:%r ] - [ %p ] %m%n    ### Save exception information to separate file ###  log4j.appender.D = org.apache.log4j.DailyRollingFileAppender  log4j.appender.D.File = ${springmvc.root}/WEB-INF/logs/error.log   log4j.appender.D.Append = true  log4j.appender.D.Threshold = ERROR   log4j.appender.D.layout = org.apache.log4j.PatternLayout  log4j.appender.D.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss} [ %t:%r ] - [ %p ] %m%n



10.  测试运行
