- // 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

- 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
- }

- 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);
