web.xml 配置如下

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

applicationContext.xml 放在WEB-INF目錄下

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

 <!-- 使用 annotation 自動注冊bean,并檢查@Controller, @Service, @Repository注解已被注入，也可以分開注釋，或者固定某個目錄下 -->

</beans>

struts2配置放在scr目錄下

<?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"

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

    <!-- 配置歡迎頁 -->
    <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>
</web-app>

action寫法目錄：src.com.action

package com.action;

import org.apache.struts2.convention.annotation.Action;
import org.apache.struts2.convention.annotation.ExceptionMapping;   
import org.apache.struts2.convention.annotation.ExceptionMappings;
import org.apache.struts2.convention.annotation.Namespace;
import org.apache.struts2.convention.annotation.Result;
import org.apache.struts2.convention.annotation.Results;
import org.apache.struts2.convention.annotation.ParentPackage;
import org.springframework.beans.factory.annotation.Autowired;

import com.opensymphony.xwork2.ActionSupport;
import com.service.PersonService;

@Namespace("/person") //訪問路徑的包名
@Results( { @Result(name = "success", location = "/index.jsp"), 
        @Result(name = "error", location = "/hello.jsp") }) 
@ExceptionMappings( { @ExceptionMapping(exception = "java.lange.RuntimeException", result = "error") }) 
public class PersonAction extends ActionSupport {

    @Autowired
    private transient PersonService personService;
    public PersonAction() {
        // TODO Auto-generated constructor stub
    } 
    @Action("login")  //訪問路徑的action名， 想要訪問selUser 這個方法 地址為 http://localhost:8080/工程名/yang/login
     public String selUser(){
            System.out.println("login-index");
            personService.selPerson();
         return SUCCESS;
         }
}

dao 寫法目錄：src.com.dao.impl 接口在 src.com.dao 此處略

package com.dao.impl;

import org.springframework.stereotype.Repository;

import com.dao.PersonDao;
@Repository("personDao")  
public class PersonDaoImpl implements PersonDao {

    public PersonDaoImpl() {
        // TODO Auto-generated constructor stub
    }

    @Override
    public void selPerson() {
        // TODO Auto-generated method stub
        System.out.println("運行dao");
    }

}

service 寫法目錄:src.com.service.impl，接口在 src.com.service 此處略

package com.service.impl;


import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;


import com.dao.PersonDao;
import com.service.PersonService;
@Service("personService")
public class PersonServiceImpl implements PersonService {


@Autowired
private transient PersonDao personDao   ;//注入的DAO

public PersonServiceImpl() {
// TODO Auto-generated constructor stub
}


@Override
public void selPerson() {
// TODO Auto-generated method stub
System.out.println("運行service");
personDao.selPerson(); 
}
}

注意增加這個jar包其他spring包，struts包自備

struts2-spring-plugin-2.3.16.jar
