4.Java代码：
（1）控制层 UserController.java
package com.ssm.controller;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import com.ssm.dao.UserDao;
import com.ssm.model.User;
@Controller
public class UserController {
@Autowired
private UserDao dao;
@RequestMapping(value="/login",method = RequestMethod.POST)
public String login(String name,String password){
if(name==null || password==null){
return "fail";
}
User user = dao.findUserByName(name);
if(user !=null && password.equals(user.getPassword())){
return "success";
}
return "fail";
}
}
（2）dao层：
①接口
package com.ssm.dao;
import com.ssm.model.User;
/**
* DAO接口层
*/
public interface UserDao {
/**
* 根据用户名查询用户信息
* @param name
* @return
*/
public User findUserByName(String name);
}
②实现类
package com.ssm.dao;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import com.ssm.mapper.UserMapper;
import com.ssm.model.User;
/**
* DAO实现层
*/
@Component
public class UserDaoImpl implements UserDao{
@Autowired
private UserMapper userMapper;
@Override
public User findUserByName(String name) {
User user = userMapper.selectUserByName(name);
return user;
}
}
（3）映射关系接口
package com.ssm.mapper;
import com.ssm.model.User;
/**
* Mapper映射类
*/
public interface UserMapper {
public User selectUserByName(String name);
}
（4）实体类
package com.ssm.model;
/**
* User映射类
*/
public class User {
private Integer id;
private String name;
private String password;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
@Override
public int hashCode() {
final int prime = 31;
int result = 1;
result = prime * result + ((name == null) ? 0 : name.hashCode());
result = prime * result
+ ((password == null) ? 0 : password.hashCode());
return result;
}
@Override
public boolean equals(Object obj) {
if (this == obj)
return true;
if (obj == null)
return false;
if (getClass() != obj.getClass())
return false;
User other = (User) obj;
if (name == null) {
if (other.name != null)
return false;
} else if (!name.equals(other.name))
return false;
if (password == null) {
if (other.password != null)
return false;
} else if (!password.equals(other.password))
return false;
return true;
}
}
