{"msglis":{"[email protected]":[{"userName":"lhf"}]}}
UserInfo 對象的屬性
private String id;
private String userName;
private String password;
private String pirture;
private Integer state;
Room 對象的屬性
private String id;
private String name;
public class MsgEntity {
private Map > msglis;//使用者房間資訊集合
private UserInfo user;//目前使用者
private Room room;//目前房間
//get and set 省略
}
//下面是我的錯誤
MsgEntity msgentity = new MsgEntity();
UserInfo u = new UserInfo();
List list = new ArrayList();
u.setUserName("lhf");
list.add(u);
Room r = new Room();
r.setName("lhf");
System.out.println("toString" +new Gson().toJson(msgentity));
//這句輸出:{"msglis":{"[email protected]":[{"userName":"lhf"}]}}
System.out.println("rtoString" +new Gson().fromJson(new Gson().toJson(msgentity), MsgEntity.class));
//報 com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected BEGIN_OBJECT but was STRING at line 1 column 13 異常
求高手指點
