这篇文章主要介绍了IDEA中如何连接数据库反转生成 Hibernate实体和配置文件，具有一定借鉴价值，感兴趣的朋友可以参考下，希望大家阅读完这篇文章之后大有收获，下面让小编带着大家一起了解一下。

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。

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; private String photo; private String email; private String yxbz; private String sorts; @Id @Column(name = "UUID") public String getUuid() { return uuid; } public void setUuid(String uuid) { this.uuid = uuid; } @Basic @Column(name = "NAME") public String getName() { return name; } public void setName(String name) { this.name = name; } @Basic @Column(name = "PASSWD") public String getPasswd() { return passwd; } public void setPasswd(String passwd) { this.passwd = 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; } public void setBirthday(Timestamp birthday) { this.birthday = birthday; } @Basic @Column(name = "PHONE") public String getPhone() { return phone; } public void setPhone(String phone) { this.phone = phone; } @Basic @Column(name = "PHOTO") public String getPhoto() { return photo; } public void setPhoto(String photo) { this.photo = photo; } @Basic @Column(name = "EMAIL") public String getEmail() { return email; } public void setEmail(String email) { this.email = email; } @Basic @Column(name = "YXBZ") public String getYxbz() { return yxbz; } public void setYxbz(String yxbz) { this.yxbz = yxbz; } @Basic @Column(name = "SORTS") public String getSorts() { return sorts; } public void setSorts(String sorts) { this.sorts = sorts; } @Override public boolean equals(Object o) { if (this == o) return true; if (o == null || getClass() != o.getClass()) return false; UserPO userPO = (UserPO) o; if (uuid != null ? !uuid.equals(userPO.uuid) : userPO.uuid != null) return false; if (name != null ? !name.equals(userPO.name) : userPO.name != null) return false; if (passwd != null ? !passwd.equals(userPO.passwd) : userPO.passwd != null) return false; if (sex != null ? !sex.equals(userPO.sex) : userPO.sex != null) return false; if (birthday != null ? !birthday.equals(userPO.birthday) : userPO.birthday != null) return false; if (phone != null ? !phone.equals(userPO.phone) : userPO.phone != null) return false; if (photo != null ? !photo.equals(userPO.photo) : userPO.photo != null) return false; if (email != null ? !email.equals(userPO.email) : userPO.email != null) return false; if (yxbz != null ? !yxbz.equals(userPO.yxbz) : userPO.yxbz != null) return false; if (sorts != null ? !sorts.equals(userPO.sorts) : userPO.sorts != null) return false; return true; } @Override public int hashCode() { int result = uuid != null ? uuid.hashCode() : 0; result = 31 * result + (name != null ? name.hashCode() : 0); result = 31 * result + (passwd != null ? passwd.hashCode() : 0); result = 31 * result + (sex != null ? sex.hashCode() : 0); result = 31 * result + (birthday != null ? birthday.hashCode() : 0); result = 31 * result + (phone != null ? phone.hashCode() : 0); result = 31 * result + (photo != null ? photo.hashCode() : 0); result = 31 * result + (email != null ? email.hashCode() : 0); result = 31 * result + (yxbz != null ? yxbz.hashCode() : 0); result = 31 * result + (sorts != null ? sorts.hashCode() : 0); return result; }}感谢你能够认真阅读完这篇文章，希望小编分享的"IDEA中如何连接数据库反转生成 Hibernate实体和配置文件"这篇文章对大家有帮助，同时也希望大家多多支持，关注行业资讯频道，更多相关知识等着你来学习!
