首先是开发包

然后是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">
<listener>
<listener-class>
org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>
<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>
<init-param>
<param-name>actionPackages</param-name>
<param-value>com.lhww</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>


<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>

然后再根目录下导入applicationContext.xml 并开启注解扫描功能

<context:component-scan base-package="com.lhww"></context:component-scan>

写个DAO用来测试下spring注入

package com.lhww.dao;

import org.springframework.stereotype.Repository;

@Repository
public class TextDao {
public String say(){
return "HELLO STRUTS2整合STRING";
}
}

最后是我们控制层

package com.lhww.action.test;

import javax.annotation.Resource;

import org.apache.struts2.convention.annotation.Action;
import org.apache.struts2.convention.annotation.Namespace;
import org.apache.struts2.convention.annotation.ParentPackage;
import org.apache.struts2.convention.annotation.Result;
import com.lhww.dao.TextDao;
import com.opensymphony.xwork2.ActionSupport;

@ParentPackage("struts-default")
@Namespace("/hello")
/*@Action(value="helloAction")
@Results({
@Result(name="login",location="WEB-INF/jsp/login.jsp")
})*/
public class HelloAction extends ActionSupport {
@Resource
private TextDao textDao;

@Action(value="login",results={
@Result(name="login",location="/WEB-INF/jsp/login.jsp")
})
public String login(){
String msg=textDao.say();
System.out.println(msg);
return "login";
}
}
