使用JavaDB-Netbeans在RESTfulWebService中执行CRUD操作

我有下面的代码

    public class Developer implements Serializable {
        private static final long serialVersionUID = 1L;
        @Id

        @Override

            if (!(object instanceof Developer)) {
                return false;
            }
            Developer other = (Developer) object;
            if ((this.id == null && other.id != null) || (this.id != null && !this.id.equals(other.id))) {
                return false;

            return true;
        }

        @Override
        public String toString() {
            return "com.service.Developer[ id=" + id + " ]";
        }

    }

这是在Netbeans中使用数据库创建restfulwebservice之后生成的java类，但是我很难找到正确的资源来插入、更新和删除数据库中的数据。谁能给我一个向导吗？非常感谢。谢谢我已经尝试了一些以前在这个网站上找到的问题的答案，但似乎没有什么能满足我的需要

如果可能的话，我希望使用netbeans的嵌入式Java DB，而不是创建MYSQL数据库。 希望我能表达我的想法

致以最诚挚的问候。

插入、更新和删除我的意思是CRUD操作代码在那里不可用。您需要编写自定义需求。但是如果你想用的话，你可以用它。请发布您的期望以及您试图纠正的内容。这不是一个提供一般帮助的帮助网站，“有人能给我一个指南吗？”不是一个具体的、可回答的问题。看见请更新您的问题，说明您需要帮助的编程问题。
