Question

im目前正在使用WebServices。我有一个正常工作的REST服务。它适用于简单的POJO列表，并公开此列表的CRUD操作。它通过InelliJ生成的工件（战争）部署在Glassfish上。现在，我想通过Hibernate将其连接到mySQL数据库。我创建了一个简单的测试项目，并且能够使用Hibernate映射对数据库进行更改。我的POJO：

 @Entity
    @Table(name = "user_table")
    public class User {
        @Id
        @Column(name = "user_id")
        private int userid;
        @Column(name = "user_name")
        private String username;
        @Column(name = "created_by")
        private String createdBy;
        @Column(name = "created_date")
        private Date createdDate;
        public int getUserid() {
            return userid;
        }
        public void setUserid(int userid) {
            this.userid = userid;
        }
        public String getUsername() {
            return username;
        }
        public void setUsername(String username) {
        this.username = username;
    }
    public String getCreatedBy() {
        return createdBy;
    }
    public void setCreatedBy(String createdBy) {
        this.createdBy = createdBy;
    }
    public Date getCreatedDate() {
        return createdDate;
    }
    public void setCreatedDate(Date createdDate) {
        this.createdDate = createdDate;
    }
}

连接到数据库的类。

package com.jcg.hibernate.maven;

import java.util.Date;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;

public class AppMain {
    static User userObj;
    static Session sessionObj;
    static SessionFactory sessionFactoryObj;
    private static SessionFactory buildSessionFactory() {
        return new Configuration().configure().buildSessionFactory();
    }
    public static void main(String[] args) {
        System.out.println(".......Hibernate Maven Example.......\n");
        try {
            sessionObj = buildSessionFactory().openSession();
            sessionObj.beginTransaction();
            for(int i = 101; i <= 105; i++) {
                userObj = new User();
                userObj.setUserid(i);
                userObj.setUsername("Editor " + i);
                userObj.setCreatedBy("Administrator");
                userObj.setCreatedDate(new Date());
                sessionObj.save(userObj);
            }
            System.out.println("\n.......Records Saved Successfully To The Database.......\n");
            sessionObj.getTransaction().commit();
        } catch(Exception sqlException) {
            if(null != sessionObj.getTransaction()) {
                System.out.println("\n.......Transaction Is Being Rolled Back.......");
                sessionObj.getTransaction().rollback();
            }
            sqlException.printStackTrace();
        } finally {
            if(sessionObj != null) {
                sessionObj.close();
            }
        }
    }
}

它在本地运行良好（数据库和服务器都在我的本地计算机上），但是我不知道如何将数据库与服务合并。我也应该将数据库部署到服务器吗？对于正确方向的任何提示，我们将不胜感激。

将数据库附加到Glassfish服务器上部署的Restfull服务的正确方法是什么？
