7 com.mw.ssm.domain包下建User类
package com.mw.ssm.domain;
public class User {
private int id;
private String name;
private String pwd;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPwd() {
return pwd;
}
public void setPwd(String pwd) {
this.pwd = pwd;
}
}
8 com.mw.ssm.dao目录下建UserDao接口
package com.mw.ssm.dao;
import java.util.List;
import org.springframework.stereotype.Repository;
import com.mw.ssm.domain.User;
@Repository("userDao")
public interface UserDao {
public List getList();
public boolean addUser(User user);
public int deleteUser(int id);
}
9 com.mw.ssm.xml包下建User.xml数据访问层文件
insert into user(id,name,pwd) values(#{id},#{name},#{pwd})
delete from user where id = #{id}
10 com.mw.ssm.service目录下建UserService接口
package com.mw.ssm.service;
import java.util.List;
import com.mw.ssm.domain.User;
public interface UserService {
public List getList();
public boolean addUser(User user);
public String deleteUser(int id);
}
11 com.mw.ssm.service.impl目录下建UserService接口的实现类
package com.mw.ssm.service.impl;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.mw.ssm.dao.UserDao;
import com.mw.ssm.domain.User;
import com.mw.ssm.service.UserService;
@Service
public class UserServiceImpl implements UserService {
@Autowired
private UserDao userDao;
@Override
public List getList() {
return userDao.getList();
}
@Override
public boolean addUser(User user) {
return userDao.addUser(user);
}
@Override
public String deleteUser(int id) {
if (userDao.deleteUser(id) == 1) {
return "删除成功";
}
return "删除失败";
}
}
12 com.mw.ssm.controller包下建控制层UserController类
package com.mw.ssm.controller;
import javax.servlet.http.HttpServletRequest;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import com.mw.ssm.domain.User;
import com.mw.ssm.service.UserService;
@Controller
public class UserController {
@Autowired
private UserService userService;
public void setUserService(UserService userService){
this.userService = userService;
}
@RequestMapping("/list")
public String getList(ModelMap map){
map.addAttribute("list", userService.getList());
return "/list.jsp";
}
@RequestMapping("addUser")
public String addUser(HttpServletRequest request, User user){
Boolean boolean1 = userService.addUser(user);
if (boolean1) {
return "/list.jsp";
}else {
return "/error.jsp";
}
}
@SuppressWarnings("finally") //用于抑制编译器的警告信息
@RequestMapping("/deleteUser")
public String deleteUser(HttpServletRequest request, int id){
try {
String str = userService.deleteUser(id);
request.setAttribute("InfoMessage", str);
} catch (Exception e) {
e.printStackTrace();
request.setAttribute("InfoMessage", "删除信息失败！具体异常信息："+e.getMessage());
}finally {
return "result";
}
}
}
