Spring Boot JPA问题：could not read a hi value

问题

could not read a hi value

解决办法

查看工程中数据库实体类的注解

@Entity
@Data
@Table(name = "user")
public class User {

    @Id
    @GeneratedValue 
    private Long id;
    private Integer age;
    private String name;
    @Column(name = "create_time")
    private Date createTime;

}

修改注解：

@GeneratedValue

或

@GeneratedValue(strategy = GenerationType.AUTO)

改为：

@GeneratedValue(strategy = GenerationType.IDENTITY)

修改后的结果：

@Entity
@Data
@Table(name = "user")
public class User {

    @Id
	@GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;
    private Integer age;
    private String name;
    @Column(name = "create_time")
    private Date createTime;

}

重启，问题解决。
