java - 从基类继承Grails域类属性

我试图创建一个域类构造函数，该结构动态地继承另一个类的属性。但是我无法使其正常工作。

这里是一个例子:

class Example1 {

  String name;
  String location;
}

class Example2 extends Example1 {

  String status;

  public Example2 (Example1 orig){
    // Code here to set this.name and this.location  to name and location from orig
    // dynamically, so adding a field in Example1 does not require me to add that
    // field here.
  }
}

最佳答案

您太辛苦了，只需复制属性即可:

class Example2 extends Example1 {

   String status

   Example2() {}

   Example2(Example1 orig) {
      this.properties = orig.properties
   }
}
