Spring与Struts整合

最近一段时间闲下来了，就想整理整理自己的知识网，查漏补缺。博客就相当于自己整理的一个过程吧。

Spring和Struts整合

1.相关Jar的引入

注意： 除了基本的Struts和Spring jar包外，要特别加入Struts里的struts2-spring-plugin.jar和Spring里的spring-web.jar。

初始化Struts和Spring

1.配置web.xml

<?xml version="1.0" encoding="UTF-8"?><web-app>    <welcome-file-list>        <wlecome-file>index.jsp</wlecome-file>    </welcome-file-list>     <!-- struts配置 -->    <filter>        <filter-name>struts2</filter-name>        <filter-class>org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter        </filter-class>    </filter>    <filter-mapping>        <filter-name>struts2</filter-name>        <url-pattern>/*</url-pattern>    </filter-mapping>    <!-- Spring配置 -->    <context-param>        <param-name>contextConfigLocation</param-name>        <param-value>/WEB-INF/classes/bean-*.xml</param-value>    </context-param>    <listener>        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>    </listener></web-app>

2.创建struts.xml和bean.xml

注意： Spring配置上下文路径时，如果你的配置文件实在源目录下的话，不能直接写/WEB-INF/bean-*.xml，项目在发布的时候会直接把配置文件拷贝到/WEB-INF/classes/目录下。

整合

1.创建Action，Service，Dao

UserAction

package cn.hts.action;import com.opensymphony.xwork2.ActionSupport;import cn.hts.service.UserService;public class UserAction extends ActionSupport{    private UserService userService;    public void setUserService(UserService userService) {        this.userService = userService;    }    public String execute() {        // TODO Auto-generated method stub        userService.save();        return SUCCESS;    }}

UserService

package cn.hts.service;import cn.hts.dao.UserDao;public class UserService {    private UserDao userDao;     public void setUserDao(UserDao userDao) {        this.userDao = userDao;    }    public void save() {        userDao.save();    }}

UserDao

package cn.hts.dao;public class UserDao {    public void save() {        System.out.println("DB:保存用户");    }}

2.IOC创建对象

bean-dao.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:p="http://www.springframework.org/schema/p"    xmlns:context="http://www.springframework.org/schema/context"    xsi:schemaLocation="        http://www.springframework.org/schema/beans        http://www.springframework.org/schema/beans/spring-beans.xsd        http://www.springframework.org/schema/context        http://www.springframework.org/schema/context/spring-context.xsd">        <bean id="userDao" class="cn.hts.dao.UserDao"></bean>  </beans>

bean-service.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:p="http://www.springframework.org/schema/p"    xmlns:context="http://www.springframework.org/schema/context"    xsi:schemaLocation="        http://www.springframework.org/schema/beans        http://www.springframework.org/schema/beans/spring-beans.xsd        http://www.springframework.org/schema/context        http://www.springframework.org/schema/context/spring-context.xsd">        <bean id="userService" class="cn.hts.service.UserService">            <property name="userDao" ref="userDao"></property>        </bean>  </beans>

bean-action.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:p="http://www.springframework.org/schema/p"    xmlns:context="http://www.springframework.org/schema/context"    xsi:schemaLocation="        http://www.springframework.org/schema/beans        http://www.springframework.org/schema/beans/spring-beans.xsd        http://www.springframework.org/schema/context        http://www.springframework.org/schema/context/spring-context.xsd">        <bean id="userAction" class="cn.hts.action.UserAction">            <property name="userService" ref="userService"></property>        </bean>  </beans>

3.Struts对Action请求的处理

struts.xml

<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE struts PUBLIC    "-//Apache Software Foundation//DTD Struts Configuration 2.5//EN"    "http://struts.apache.org/dtds/struts-2.5.dtd">    <struts>    <package name="user" namespace="/" extends="struts-default">        <action name="user" class="userAction" method="execute">            <result name="success">/WEB-INF/index.jsp</result>        </action>    </package>      </struts>

注意： 原先struts配置文件中class属性的值是有action的类名，现在变为由Spring来管理对象的创建。所以用的IOC容器中userAction。

结果

在浏览器中输入地址查看效果

控制台输出

注意：
因为没做跳转事件，所以浏览器的地址直接访问了action。
