介面返回統一格式為：

1 {
2 'result': 1,
3 'errorCode': '',
4 'errorMsg': '成功',
5 'data': {'a': 111, 'b': '222'}
6 }

程式碼如下：

 1 import java.io.Serializable;
 2 import java.util.HashMap;
 3 import java.util.Map;
 4 
 5 public class ResultMessage implements Serializable {
 6     /**
 7      * 返回格式：
 8      * {'result': 1,
 
 9      * 'errorCode': '',
10      * 'errorMsg': '成功',
11      * 'data': {'a': 111, 'b': '222'}}
12      */
