Spring集成Struts步骤:

集成Struts
1,拷贝jar和xml(struts2.xml,struts2的jar包,web.xml)
    1)相关的jar以及spring-web.*.jar,struts2-spring-plugin.*.jar
    2)struts.xml
    3)web.xml

①:Struts相关的包:

②:Spring中需要的jar包:

③:Spring和Struts连接的包:

2)Struts.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>
    <include file="struts-default.xml"></include>
    <package name="hello" extends="struts-default">
编写struts的配置文件:
注意,在action的class属性,填写的是这个Action在applicationContext.xml中对应的bean的id;
        <action name="stu_*"  class="Staction" method="{1}">
            <result name="list">/WEB-INF/views/Student.jsp</result>
        </action>
    </package>
</struts>     
   

   3)web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app id="WebApp_9" version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
　　在web.xml中添加listener
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
　 在web.xml中添加spring框架启动的加载的配置文件路径:

    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:ApplicationContext.xml</param-value>
    </context-param>


    <filter>
        <filter-name>struts2</filter-name>
        <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
    </filter>

    <filter-mapping>
        <filter-name>struts2</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

</web-app>

2,编写Action;

package com.gxxy.action;

import java.util.List;

import javax.servlet.http.HttpServletRequest;

import org.apache.struts2.ServletActionContext;

import com.gxxy.domain.Student;
import com.gxxy.service.IStudentServiceDAO;
import com.opensymphony.xwork2.ActionSupport;

public class StudentAction extends ActionSupport {

    private static final long serialVersionUID = 1L;

    private IStudentServiceDAO service;

    public void setService(IStudentServiceDAO service) {
        this.service = service;
    }

    public String list() throws Exception {
        List<Student> list = service.list();
        HttpServletRequest request = ServletActionContext.getRequest();
        request.setAttribute("stu", list);
        return "list";
    }
}

3,在applicationContext.xml中配置Action;
    * 注意, 因为Action不是线程安全的, 所以需要每次请求创建一个新的Action, 所以在配置这个bean的时候
        scope需要填写prototype

<!-- 配置Action -->
    <bean id="Staction" class="com.gxxy.action.StudentAction" scope="prototype">
        <property name="service" ref="service"></property>
    </bean>

4,编写struts的配置文件:
    * 注意,在action的class属性,填写的是这个Action在applicationContext.xml中对应的bean的id;
5,在web.xml中添加listener
6,在web.xml中添加spring框架启动的加载的配置文件路径:

   <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext.xml</param-value>
    </context-param>

ApplicationContext.xml的所有配置:包括Hibernate配置:

<?xml version="1.0" encoding="UTF-8"?>
