一、新建maven项目，配置ssh框架pom的最低支持
1、新建一个maven项目
2、添加一个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>limanman</display-name> </web-app>
3、基本ssh框架pom.xml配置
<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.winssage.fengshu</groupId> <artifactId>winssage</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>war</packaging> <name>winssage</name> <url>http://maven.apache.org</url> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> </properties> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.10</version> <scope>test</scope> </dependency> <!-- 添加SSH依赖 --> <!-- Struts2 --> <dependency> <groupId>org.apache.struts</groupId> <artifactId>struts2-core</artifactId> <version>2.3.1</version> </dependency> <dependency> <groupId>org.apache.struts</groupId> <artifactId>struts2-spring-plugin</artifactId> <version>2.3.1</version> </dependency> <!-- 添加Hibernate依赖 --> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-core</artifactId> <version>3.6.5.Final</version> </dependency> <dependency> <groupId>commons-dbcp</groupId> <artifactId>commons-dbcp</artifactId> <version>1.4</version> </dependency> <!-- 添加Log4J依赖 --> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>1.2.16</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>1.6.1</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-nop</artifactId> <version>1.6.4</version> </dependency> <!-- 添加javassist --> <dependency> <groupId>javassist</groupId> <artifactId>javassist</artifactId> <version>3.11.0.GA</version> </dependency> <!-- 添加Spring依赖 --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>3.1.1.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-beans</artifactId> <version>3.1.1.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>3.1.1.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>3.1.1.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-orm</artifactId> <version>3.1.1.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>3.1.1.RELEASE</version> </dependency> </dependencies> </project>
二、maven webproject 整合struts2
1、web.xml 加入中心拦截器配置
<filter> <filter-name>struts2</filter-name> <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class> </filter> <filter-mapping> <filter-name>struts2</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>
2、加入log4j.xml
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE log4j:configuration PUBLIC "-//Apache//DTD Log4j 1.2//EN" "http://logging.apache.org/log4j/docs/api/org/apache/log4j/xml/log4j.dtd"> <log4j:configuration> <appender class="org.apache.log4j.ConsoleAppender" name="RootConsoleAppender"> <param name="Threshold" value="debug" /> <layout class="org.apache.log4j.PatternLayout"> <param name="ConversionPattern" value="%d{ABSOLUTE} %-5p [%c{1}] %m%n" /> </layout> </appender> <category name="com.fengshu.limanman.winssage"> <priority value="debug" /> </category> <category name="org.springframework"> <priority value="warn" /> </category> <category name="org.hibernate"> <priority value="warn" /> </category> <category name="org.dbunit"> <priority value="warn" /> </category> <category name="com.mchange.v2"> <priority value="warn" /> </category> <category name="org.apache"> <priority value="warn" /> </category> <category name="org.logicalcobwebs"> <priority value="warn" /> </category> <category name="com.opensymphony"> <priority value="warn" /> </category> <root> <level value="info" /> <appender-ref ref="RootConsoleAppender" /> </root> </log4j:configuration>
3、引入struts2.xml 根据约定由于配置原则，将此配置文件放在更目录即可
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN" "http://struts.apache.org/dtds/struts-2.0.dtd"> <struts> <package name="fengshu" namespace="/user" extends="struts-default"> <!--<action name="user" class="com.fengshu.limanman.winssage.controller.LoginController"> <result name="success">/pages/index.jsp</result> </action>--> </package> </struts>
4、建一个测试jsp在webapp/pages/index.jsp
<%@ page language="java" contentType="text/html; charset=utf-8" pageEncoding="utf-8"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <title>Insert title here</title> </head> <body>hello limanman </body> </html>
5、写一个controller
package com.fengshu.limanman.controller; import org.apache.log4j.Logger; import com.opensymphony.xwork2.ActionSupport; public class LoginController extends ActionSupport { private static final long serialVersionUID = 1L; private Logger log=Logger.getLogger(this.getClass()); public String login() { log.info("hello i am limanman"); return "succerss"; } }
6、配置struts2.xml
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN" "http://struts.apache.org/dtds/struts-2.0.dtd"> <struts> <package name="fengshu" namespace="/" extends="struts-default"> <action name="user" class="com.fengshu.limanman.controller.LoginController"> <result name="success">/pages/index.jsp</result> </action> </package> </struts>
7、暂时注释掉pom.xml中的struts2-spring-plugin
因为还没有整合spring，如果加入struts2-spring-plugin将会报空指针异常，整合spring后需要加入此jar包，下面将不再提及。
8、配置jetty运行环境，开发的时候我们一般使用jetty服务器，而不用tomcat
在pom.xml中加入jetty插件，并且配置根目录目录
<build> <plugins> <!-- 配置加入jetty服务器，开发时我们一般使用jetty服务器 --> <plugin> <groupId>org.mortbay.jetty</groupId> <artifactId>jetty-maven-plugin</artifactId> <configuration> <!-- 设置扫描target/classes内部文件变化时间间隔 --> <scanIntervalSeconds>2</scanIntervalSeconds> <webApp> <contextPath>/limanman</contextPath> </webApp> </configuration> </plugin> <!-- compiler插件, 设定JDK版本 --> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>3.0</version> <configuration> <source>1.6</source> <target>1.6</target> <showWarnings>true</showWarnings> </configuration> </plugin> <!-- war打包插件, 设定war包名称不带版本号 --> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-war-plugin</artifactId> <version>2.3</version> <configuration> <warName>winssage</warName> </configuration> </plugin> <!-- eclipse插件, 设定wtp版本 --> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-eclipse-plugin</artifactId> <version>2.9</version> <configuration> <downloadSources>true</downloadSources> <downloadJavadocs>false</downloadJavadocs> <wtpversion>2.0</wtpversion> </configuration> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-dependency-plugin</artifactId> <executions> <execution> <id>install</id> <phase>install</phase> <goals> <goal>sources</goal> </goals> </execution> </executions> </plugin> <!-- 用于支持跨模块加载配置文件 --> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-resources-plugin</artifactId> <version>2.5</version> <configuration> <encoding>UTF-8</encoding> <nonFilteredFileExtensions> <nonFilteredFileExtension>dll</nonFilteredFileExtension> <nonFilteredFileExtension>so</nonFilteredFileExtension> </nonFilteredFileExtensions> </configuration> </plugin> </plugins> </build>
9、第一个里程碑,第一次运行项目
（1）jetty:run -Djetty.port=9080 -Dmaven.test.skip=true 跑起项目
(2)效果截图
三、将spring 整合进来
1、web.xml加入spring监听
<context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath*:META-INF/spring/ApplicationContext.xml</param-value> </context-param> <!-- Spring Listener --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener>
2、将strut2交给spring管理
（1）修改strut2.xml
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN" "http://struts.apache.org/dtds/struts-2.0.dtd"> <struts> <package name="fengshu" namespace="/" extends="struts-default"> <action name="user" class="loginController"> <result name="success">/pages/index.jsp</result> </action> </package> </struts>
<bean id="loginController" class="com.fengshu.limanman.controller.LoginController"> </bean>
(3)运行 it is aok!
四、spring再整合hibernate
1、加入datasource
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"> <property name="driverClassName" value="com.mysql.jdbc.Driver"> </property> <property name="url" value="jdbc:mysql://localhost:3306/ddd"> </property> <property name="username" value="root"></property> <property name="password" value="root"></property> </bean>
2、加入sessionFactory
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean"> <property name="dataSource"> <ref bean="dataSource" /> </property> <property name="annotatedClasses"> <list> <value>com.winssage.bslogic.core.User</value> </list> </property> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect"> org.hibernate.dialect.Mysql5Dialect </prop> <prop key="hibernate.show_sql">true</prop> <prop key="hibernate.hbm2ddl.auto">update</prop> </props> </property> </bean>
3、运行项目后报错
经检查发现是因为没有mysql驱动，也没有hibernate-anation 包
给改hibernate pom.xml 配置
<!-- 添加Hibernate依赖 --> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate</artifactId> <version>3.2.6.ga</version> <type>jar</type> <scope>compile</scope> <exclusions> <exclusion> <artifactId>jta</artifactId> <groupId>javax.transaction</groupId> </exclusion> </exclusions> </dependency> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-annotations</artifactId> <version>3.2.0.ga</version> <type>jar</type> <scope>compile</scope> </dependency> <dependency> <groupId>org.hibernate</groupId> <artifactId>ejb3-persistence</artifactId> <version>1.0.0</version> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.0.5</version> </dependency>
4、再次启动
已自动更新了表，注意应该讲hibernate.hbm2ddl.auto设置为create才能自动创建表
到此hibernate已经成功添加进来
