1，spring4支持泛型注入，dao层非常简化。User实体类，dao接口，dao实现类，service接口（下载地址：链接：https://pan.baidu.com/s/1PJhLcylNTWcV4nqtikUhKQ 密码：harp）略。
service实现类：
package com.cruise.service.impl;

import java.util.List;

import javax.annotation.Resource;

import org.springframework.stereotype.Service;

import com.cruise.dao.BaseDao;
import com.cruise.entity.User;
import com.cruise.service.UserService;

@Service("userService")
public class UserServiceImpl implements UserService{

       @Resource
       private BaseDao baseDao;

       @Override
       public void saveUser(User user) {
              baseDao.save(user);
       }

       @Override
       public void updateUser(User user) {
              baseDao.update(user);
       }

       @Override
       public User findUserById(int id) {
              return baseDao.get(User.class, id);
       }

       @Override
       public void deleteUser(User user) {
              baseDao.delete(user);
       }

       @Override
       public List findAllList() {
              return baseDao.find("from User");
       }

       @Override
       public User findUserByNameAndPassword(User user) {
              return baseDao.get("from User u where u.userName=? and u.password=?",new Object[]{user.getUserName(),user.getPassword()});
       }
}
UserAction类
package com.cruise.action;

import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;

import org.apache.struts2.interceptor.ServletRequestAware;

import com.cruise.entity.User;
import com.cruise.service.UserService;
import com.opensymphony.xwork2.ActionSupport;

public class UserAction extends ActionSupport implements ServletRequestAware{

       private HttpServletRequest request;

       @Resource
       private UserService userService;

       private User user;
       private String error;

       public User getUser() {
              return user;
       }

       public void setUser(User user) {
              this.user = user;
       }

       public String getError() {
              return error;
       }

       public void setError(String error) {
              this.error = error;
       }

       @Override
       public void setServletRequest(HttpServletRequest request) {
              this.request=request;
       }

       public String login()throws Exception{
              HttpSession session=request.getSession();
              User currentUser=userService.findUserByNameAndPassword(user);
              if(currentUser!=null){
                     session.setAttribute("currentUser", currentUser);
                     return SUCCESS;
              }else{
                     error="用后名或者密码错误！";
                     return ERROR;
              }
       }
}
数据库建表

Create Table

CREATE TABLE `t_user` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `password` varchar(20) DEFAULT NULL,
  `userName` varchar(20) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8

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



    /User" extends="struts-default">
