gwt - GWT 数组列表

Question

I have two different model class,

public class ModelDto implements IsSerializable{
     public ModelDto {}
     private Integer id;
     private String name;
     private ArrayList<Test> name;
}

public class Test implements IsSerializable{
     public Test {}
     private Integer id;
     private String name;
     private ArrayList<Test> name;
}

I want to make a RPC call like

ModelDto getModel();

How to achieve this? I know that the issue is basic serialization. but I want to know that how to pass a ArrayList in RPC If not posible any alternatives?.

听起来你的问题implements IsSerializable我怀疑你的课程没有实现com.google.gwt.user.client.rpc.IsSerializable.

它应该实现一个java.io.Serializable或 GWT com.google.gwt.user.client.rpc.IsSerializable.（两者一起没有问题）。

关于你的默认构造函数。它应该是一个empty constructor. 例如

 public ModelDto() {

}

package structures仅当您在进行上述更改（如...等）后仍然面临问题时，才会出现这两点的大多数问题，请参阅此。
