java 接口返回格式

接口返回统一格式为：

{
'result': 1,
'errorCode': '',
'errorMsg': '成功',
'data': {'a': 111, 'b': '222'}
}

代码如下：

import java.io.Serializable;
import java.util.HashMap;
import java.util.Map;

public class ResultMessage implements Serializable {
    /**
     * 返回格式：
     * {'result': 1,
     * 'errorCode': '',
     * 'errorMsg': '成功',
     * 'data': {'a': 111, 'b': '222'}}
     */
    private int result = 0;
    private String errorCode = "";
    private String errorMsg;
    private Map<String, Object> data = new HashMap();

    private ResultMessage() {
    }

    public static ResultMessage create() {
        return new ResultMessage();
    }

    public int getResult() {
        return this.result;
    }

    public String getErrorCode() {
        return this.errorCode;
    }

    public String getErrorMsg() {
        return this.errorMsg;
    }

    public void raise(int result, String errorCode,String errorMsg) {
        this.result = result;
        this.errorCode = errorCode;
        this.errorMsg = errorMsg;
    }

    public void put(String key, Object obj) {
        this.data.put(key, obj);
    }

    public Map<String, Object> getData() {
        return this.data;
    }
}


ResultMessage resultMessage = ResultMessage.create();


resultMessage.put("a", 111);
resultMessage.put("b", "222");
resultMessage.raise(1,"", "成功");
