spring data jpa创建有表注释，字段注释代码块

@Entity
@Table(name = "user")
@org.hibernate.annotations.Table(appliesTo = "user",comment = "用户表")
public class User{
 
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;
 
    @Column(nullable = true,columnDefinition = "varchar(100) default '' comment '用户名'")
    private String name;
 
    @Column(nullable = true,columnDefinition = "varchar(100) default '' comment '邮箱'")
    private String email;
 
    @Column(columnDefinition = "int(11) default 0 comment '性别 0:男 1:女'")
    private int sex;
 
    protected User(){
 
    }
 
    public User(Long id, String name, String email) {
        this.id = id;
        this.name = name;
        this.email = email;
    }
}

@Table 和 @org.hibernate.annotations.Table(appliesTo = "user",comment = "用户表") 要同时存在数据库表才可以创建成功；

当然，如果你不需要表注释的话，只有@Table就可以了

 

@GeneratedValue(strategy = GenerationType.IDENTITY)  为主键的生成策略，我试着给Id加注释时发现 @Column和@GeneratedValue冲突，导致创建表SQL语句出错。
