1.bean目录下的user类
public class User {
public User() {
}
public User(int id, String username, String password) {
this.id = id;
this.username = username;
this.password = password;
}
public User(String username, String password) {
this.username = username;
this.password = password;
}
private int id;
private String username;
private String password;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
@Override
public String toString() {
return "User{" +
"id=" + id +
", username='" + username + '\'' +
", password='" + password + '\'' +
'}';
}
}
2.controller目录下UserController类
import com.zhongruan.bean.User;
import com.zhongruan.service.IUserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
import java.util.List;
@Controller
@RequestMapping("/user")
public class UserController {
@Autowired
private IUserService userService;
@RequestMapping("/login.do")
public ModelAndView login(User user){
boolean flag = userService.login(user.getUsername(), user.getPassword());
ModelAndView modelAndView=new ModelAndView();
if(flag){
modelAndView.setViewName("main");
}else {
modelAndView.setViewName("../failer");
}
return modelAndView;
}
@RequestMapping("/findAll.do")
public ModelAndView findAll(){
List<User> userList = userService.findAll();
ModelAndView modelAndView = new ModelAndView();
modelAndView.addObject( "userList", userList);
modelAndView.setViewName( "user-list" );
return modelAndView;
}
}
3.Dao目录下的dao层
import com.zhongruan.bean.User;
import java.util.List;
public interface UserDao {
User findUserByUserName(String username);
List<User> findAll();
}
4.service目录下的IUserService接口和UserService实现类
import com.zhongruan.bean.User;
import java.util.List;
public interface IUserService {
boolean login(String username,String password);
List<User> findAll();
}
import com.zhongruan.bean.User;
import com.zhongruan.dao.UserDao;
import com.zhongruan.service.IUserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import java.util.List;
@Service
public class UserService implements IUserService {
@Autowired
private UserDao userDao;
@Override
public boolean login(String username, String password) {
User user = userDao.findUserByUserName(username);
if (user!=null && user.getPassword().equals(password)){
return true;
}
return false;
}
@Override
public List<User> findAll() {
return userDao.findAll();
}
}
