hibernate怎么通过实体类创建数据库表
我想通过Java的实体类创建数据库表，我该怎么做啊！搞了好长时间没弄出来，求大神帮忙啊！ --------------------编程问答-------------------- 这个网上很多 。搜搜看看。 --------------------编程问答--------------------
import java.util.HashSet;
import java.util.Set;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.OneToMany;
@Entity
public class UserInfo {
private int id;
private String username;
private String userpwd;
private String userphone;
private String others;
private Set<HireInfo> hireinfos = new HashSet<HireInfo>();
private Set<Magdebrug> magdebrugs = new HashSet<Magdebrug>();
@Id
@GeneratedValue
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getUserpwd() {
return userpwd;
}
public void setUserpwd(String userpwd) {
this.userpwd = userpwd;
}
public String getUserphone() {
return userphone;
}
public void setUserphone(String userphone) {
this.userphone = userphone;
}
public String getOthers() {
return others;
}
public void setOthers(String others) {
this.others = others;
}
@OneToMany(mappedBy="userinfo")
public Set<HireInfo> getHireinfos() {
return hireinfos;
}
public void setHireinfos(Set<HireInfo> hireinfos) {
this.hireinfos = hireinfos;
}
@OneToMany(mappedBy="userinfo")
public Set<Magdebrug> getMagdebrugs() {
return magdebrugs;
}
public void setMagdebrugs(Set<Magdebrug> magdebrugs) {
this.magdebrugs = magdebrugs;
}
}
public static void main(String[] args) {
Session session=HibernateSessionFactory.getSession();
}
运行一下就可以了 --------------------编程问答-------------------- 其实这个不值得推荐，应为表设计也是比较复杂的，尤其是大一些的系统。 --------------------编程问答--------------------
配置hibernate还得加上这个
<prop key="hibernate.hbm2ddl.auto">update</prop>
补充：Java , Web 开发
