1.1.1 给User实体类添加校验
java
package com.geji.pojo;
import com.fasterxml.jackson.annotation.JsonIgnore;
import jakarta.validation.constraints.Email;
import jakarta.validation.constraints.NotEmpty;
import jakarta.validation.constraints.NotNull;
import jakarta.validation.constraints.Pattern;
import lombok.Data;
import java.time.LocalDateTime;
//lombok 在编译阶段,为实体类自动生成setter getter toString
// pom文件中引入依赖 在实体类上添加注解
@Data
public class User {
@NotNull
private Integer id;//主键ID
private String username;//用户名
@JsonIgnore//让springmvc把当前对象转换成json字符串的时候,忽略password,最终的json字符串中就没有password这个属性了
private String password;//密码
@NotEmpty
@Pattern(regexp = "^\\S{1,10}$")
private String nickname;//昵称
@NotEmpty
@Email
private String email;//邮箱
private String userPic;//用户头像地址
private LocalDateTime createTime;//创建时间
private LocalDateTime updateTime;//更新时间
}
1.1.1 UserController中添加update方法
java
@PutMapping("/update")
public Result update(@RequestBody @Validated User user) {
userService.update(user);
return Result.success();
}
1.1.2 UserService中添加update接口
java
package com.geji.service;
import com.geji.pojo.User;
public interface UserService {
//根据用户名查找用户
User findByUserName(String username);
//根据用户名和密码注册
void register(String username, String password);
void update(User user);
}
1.1.3 UserServiceImpl中添加update实现类
java
@Override
public void update(User user) {
user.setUpdateTime(LocalDateTime.now());
userMapper.update(user);
}
1.1.4 UserMapper中添加update方法
java
package com.geji.mapper;
import com.geji.pojo.User;
import org.apache.ibatis.annotations.Insert;
import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Select;
import org.apache.ibatis.annotations.Update;
@Mapper
public interface UserMapper {
//根据用户名查询用户
@Select("select * from user where username=#{username}")
User findByUserName(String username);
//添加
@Insert("insert into user(username,password,create_time,update_time)" +
" values(#{username},#{password},now(),now())")
void add(String username, String password);
@Update("update user set nickname=#{nickname},email=#{email},update_time=#{updateTime} where id=#{id}")
void update(User user);
}
1.1.5 使用postman测试
