java - 如何使用嵌套数组解析 JSON 到对象

Question

我正在查看一些示例，但找不到任何解决我的问题的方法。我想问题是微不足道的，但我不能我做错了什么。我有看起来很简单的 JSON:

{
  "value" : 120,
  "objects" : [
    {
      "object_id" : 1,
      "description" : "First object",
      "flag" : false
    },
    {
     "object_id" : 2,
      "description" : "Second object",
      "flag" : true
    }
  ]
}

我为它创建了一个模型:

一般响应:

public class GeneralResponse {

    public int value;
    public List<NestedObject> objects;

}

嵌套对象:

public class NestedObject {

    public int object_id;
    public String description;
    public boolean flag;

}

我尝试这样解析它:

GeneralResponse response = new Gson().fromJson(myJSONstring, GeneralResponse.class);

我收到一个错误:

com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected a string but was BEGIN_OBJECT at line 4 column 6 path $.objects[0]

问题代码有错误，作者后:

NestedObject is an enum with fields and this cause error.
