用GSON解析JSON内部字段

Question

我是JSON的新手，与我研究过的任何其他解析方法相比，我喜欢GSON Api的强大和直截了当。
我想解析一个相当复杂的JSON（使用GSON)，就结构而言，它类似于下面的JSON：

[
  {  
  "name": "Steve",
  "age": 42,
  "description": null,
  "email1": "[e-mail]",
  "email2": null,
  "address1": {
    "type": "home",
    "shippingMethod": "Charge by quantity",
    "street": "Sunrise Ave",
    "streetNo": 17
     },
   "address2": {
    "type": "office",
    "shippingMethod": null,
    "street": "Sunset Ave",
    "streetNo": 71
     },
   "anotherField": "another value"
   },
   {
   "name": "Johnny",
   ...
   "anotherField": "some other value"
   }
]  

public class Client {
  String name;
  int age;
  String description;
  String email1;
  String email2;
  ClientAddress address1;
  ClientAddress address2;
  String anotherfield;
  ..
  getters() and setters()

  public class ClientAddress {
    String type;
    String shippingMethod;
    String street;
    int streetNo;
    ..
    getters() and setters()
  }
}

Client[] clientsArray= (new Gson()).fromJson(jsonClients, Client[].class);

clientsArray[i].getAddress1().getShippingMethod();

我哪里出了问题？
是否有一种创建我所缺少的类的特殊方法？

注意：从结构的角度来看，我的JSON对象是完全有效的。如果您看到任何错误，这可能是因为当我手动创建上面的虚拟/演示时，它们出现了滑动。

只是为了遵循GSON集合的良好实践，尝试改变

 Client[] clientsArray= (new Gson()).fromJson(jsonClients, Client[].class);

到

 Type collectionType = new TypeToken<List<Client>>(){}.getType();
 List<Client> clientsArray = (new Gson()).fromJson(jsonClients, collectionType);
