java修改⽤户密码全代码
java实现修改密码
前段时间⼀直在写东西，本来不想把⽤户这块的东西放出来，想了想，还是弄⼀个修改密码功能实现⼀下,⾸先介绍⼀下我这个项⽬，他有session等验证，所以搞起来得和正式的项⽬⼀样得实现，废话不多说，直接开始，先是搞⼀个请求去查都有哪些账号

这就是查到的数据返回到前端后展⽰的，我不懂前段端，所以只能这个样⼦了
实体类,get set 和toString⾃⼰⽣成⼀下，我这⾥为了节约空间就只写那些参数了
public class User {
private Integer id;
private String username;//账号
private String user_password;//密码
private Integer identity;//权限
//get  set  toString 略多省工厂停产
}
查询都有哪些⽤户controller
//查询有哪些账号Controller
@RequestMapping("getuser")
@ResponseBody
public JSONArray getUser(){
List<User> res =null;
JSONArray json =null;
res = userService.findUser();
json = JSONArray.fromObject(res);
return json;
}
接下来是dao层代码,
public interface UserDao {
/
/ ⽤户登录
public User verifyUser(User user);
//库⾥⾯查询有哪些账号
List<User>findUser();
// 修改密码时查询⼀下密码对错
User managUser(String userName);
// 更新密码
int uodataPassword(@Param("username") String username, @Param("x_password") String x_password); }
再就是service和他的实现类的代码
public interface UserService {
public User userLogin(User user);
// 查询有哪些⽤户
List<User>findUser();
// 修改密码查询账号对⽐密码
User managUser(String userName);
// 更新密码
int uodataPassword(@Param("username") String username, @Param("x_password") String x_password); }
实现类代码
@Service
public class UserServiceimpl implements UserService {
@Autowired
private UserDao userDao;
// 验证登录
public User userLogin(User user){
return userDao.verifyUser(user);
}
public List<User>findUser(){
return userDao.findUser();
}
public User managUser(String userName){
return userDao.managUser(userName);
}
public int uodataPassword(String username, String x_password){
return userDao.uodataPassword(username, x_password);
}
}
