public enum ResultEnum {

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

/**

public class ResultUtil{


private static final Logger LOGGER = LoggerFactory.getLogger(ResultUtil.class);

/**
* 請求成功返回
* @param object
* @return

public static ResponseMessage success(Object object){
ResponseMessage msg=new ResponseMessage();
msg.setCode(200);
msg.setMsg("請求成功");
msg.setResult(object);
LOGGER.info("請求數據成功,數據值爲:"+object);
return msg;
}
public static ResponseMessage success(){
LOGGER.info("請求數據成功");
return success(null);
}

public static ResponseMessage error(Integer code,String resultmsg){
ResponseMessage msg=new ResponseMessage();
msg.setCode(code);
msg.setMsg(resultmsg);
return msg;
}


}

 

 

使用:

Controller 返回值爲ResponseMessage

 

return ResultUtil.success(obj);
