 applicationContext.xml  放在WEB-INF目录下

 struts2配置 放在scr目录下

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

    <!-- 配置欢迎页 -->
    <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>
</web-app>

 action写法  目录：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") //访问路径的包名
@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")  //访问路径的action名， 想要访问selUser 这个方法 地址为 http://localhost:8080/工程名/yang/login
     public String selUser(){
            System.out.println("login-index");
            personService.selPerson();
         return SUCCESS;
         }
}

 dao 写法  目录：src.com.dao.impl  接口在 src.com.dao 此处略

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("运行dao");
    }
 
}

 service 写法 目录:src.com.service.impl，接口在 src.com.service 此处略 

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("运行service");
personDao.selPerson();
}
}

 注意增加这个jar包  其他spring包，struts包自备

struts2-spring-plugin-2.3.16.jar
