目录

1.搭建环境

在idea下可以在创建module时候选择，注意WEB-INF下的classes和lib两个目录需要手动创建，并且对应的配置文件和依赖的lib需要手动拷贝到这两个文件夹下

2.编写Action，Server，Dao类

package per.liyue.integration;

import org.springframework.stereotype.Repository;

@Repository(value = "userDao")

public class UserDao

{

    public void Save()

    {

        System.out.println("操作数据保存了数据");

    }

}


package per.liyue.integration;

import org.springframework.stereotype.Service;

import javax.annotation.Resource;

@Service(value = "userService")//这里等于配置文件中<bean id="userDao" class="per.liyue.springlearing.structure.UserDao"></bean>

                               //的方式

public class UserService

{

    @Resource(name = "userDao")

    private UserDao userDao;

    public void Save()

    {

        userDao.Save();

    }

}
package per.liyue.integration;

import com.opensymphony.xwork2.ActionSupport;

import javax.annotation.Resource;

//@Controller(value = "userAction")

public class UserAction extends ActionSupport

{

    @Resource(name = "userService")

    private UserService userService;

    @Override

    public String execute()

    {

        userService.Save();

        return SUCCESS;

    }

}

3.配置bean.xml文件，建议按照类的不同来分类。例如将所有Action类的配置都写入到bean-Action.xml下面，其他同理

<?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"

       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">

        <context:component-scan base-package="per.liyue.integration"></context:component-scan>

</beans>
<?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"

       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">

        <context:component-scan base-package="per.liyue.integration"></context:component-scan>

</beans>
<?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"

       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">

        <context:component-scan base-package="per.liyue.integration"></context:component-scan>

</beans>

4.配置struts.xml

4.1修改jsp

<%--

  Created by IntelliJ IDEA.

  User: liyue

  To change this template use File | Settings | File Templates.

--%>

<%@ page contentType="text/html;charset=UTF-8" language="java" %>

<html>

  <head>

    <title>First integration</title>

  </head>

  <body>

  Hello !

  </body>

</html>

4.2将Action类配置到xml文件中

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

<!DOCTYPE struts PUBLIC

        "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"

        "http://struts.apache.org/dtds/struts-2.3.dtd">

<struts>

    <package name="user" extends="struts-default">

        <action name="user" class="per.liyue.integration.UserAction" method="execute">

            <result name="success">/index.jsp</result>

        </action>

    </package>

</struts>

5.配置Web.xml文件

struts2的配置如之前，spring的配置可以参考api文档（搜索关键字context-param），将完整的例子拷贝到我们的代码中。

如果spring配置文件的路径放到了classes下，需要手动拷贝

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

<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"

         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"

         version="3.1">

    <!--

    1.struts2 配置

    -->

    <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>

    <!--

    2.spring配置：具体配置内容可以在api文档中搜索关键字context-param查找到

    -->

    <context-param>

        <param-name>contextConfigLocation</param-name>

        <!--多个xml文件用空格或者逗号隔开，可以用*来全局匹配-->

        <param-value>/WEB-INF/classes/bean-*.xml</param-value>

    </context-param>

    <listener>

        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>

    </listener>

</web-app>
