运行结果及报错内容
我的解答思路和尝试过的方法
这是xml文件的sql语句
INSERT INTO
t_user (username, password, salt, phone, email, gender, avatar, is_delete, created_user, created_time, modified_user, modified_time)
VALUES
(#{username}, #{password}, #{salt}, #{phone}, #{email}, #{gender}, #{avatar}, #{isDelete}, #{createdUser}, #{createdTime}, #{modifiedUser}, #{modifiedTime})
这是那个接口
/**
* 向表中添加数据
* @return
*/
Integer insert(User user);
这是两个bean感觉问题应该不是很大
@Data
public class User extends BaseEntity implements Serializable {
private Integer uid;
private String username;// VARCHAR(20) NOT NULL UNIQUE COMMENT '用户名',
private String password ;//CHAR(32) NOT NULL COMMENT '密码',
private String salt ;//CHAR(36) COMMENT '盐值',
private String phone ;//VARCHAR(20) COMMENT '电话号码',
private String email ;//VARCHAR(30) COMMENT '电子邮箱',
private Integer gender ;//INT COMMENT '性别:0-女,1-男',
private String avatar;// VARCHAR(50) COMMENT '头像',
private Integer isDelete;// INT COMMENT '是否删除:0-未删除,1-已删除',
}
@Data
public class BaseEntity {
private String createdUser; // VARCHAR(20) COMMENT '日志-创建人',
private Date createdTime; // DATETIME COMMENT '日志-创建时间',
private String modifiedUser; // VARCHAR(20) COMMENT '日志-最后修改执行人',
private Date modifiedTime;// DATETIME COMMENT '日志-最后修改时间',
}
我想要达到的结果
这是测试类
@Autowired
Usermapper usermapper;
@Test
void contextLoads() {
User user = new User();
user.setUsername("八重神子");
Integer insert = usermapper.insert(user);
}
