idea hibernate jpa 生成实体类的实现

idea hibernate jpa 生成实体类的实现

本篇博客记录下 IDEA 中连接数据库反转生成 Hibernate 实体和配置文件。

1. 打开 DataBase 窗口，添加数据源

到了这一步数据源已添加好。

2. 添加 hibernat 持久层支持，生成实体 Bean /配置文件，这一步要去plugs那里下载一个hibernate插件，不然你的persistence是出不来的

然后选择数据源，选择包，添加生成 Bean 的后缀，选择表，选择生成 xml 配置文件还是注解。

OK，结束

如果你选择生成带 JPA 注解类，映射文件是可以省略的，相反如果你生成映射文件，JPA 注解也可以省略。

看你喜欢哪种方式

生成注解例子

@Entity

@Table(name = "user", schema = "db_test", catalog = "")

public class UserPO {

private String uuid;

private String name;

private String passwd;

private String sex;

private Timestamp birthday;

private String phone;

@Id

@Column(name = "UUID")

}

@Basic

@Column(name = "NAME")

}

@Basic

@Column(name = "PASSWD")

}

@Basic

@Column(name = "SEX")

public String getSex() {

return sex;

}

public void setSex(String sex) {

this.sex = sex;

}

@Basic

@Column(name = "BIRTHDAY")

public Timestamp getBirthday() {

return birthday;

}

}

@Basic

@Column(name = "PHONE")

}

@Basic

}

@Basic

@Column(name = "SORTS")

public String getSorts() {

return sorts;

}

public void setSorts(String sorts) {

this.sorts = sorts;

}

@Override

}

@Override

public int hashCode() {
