bean中屬性名和json不一致解決方案（請求和響應） 原

使用springboot開發rest接口，

第三方定義的接口的請求和響應格式要求如下，沒有按照正常的駝峯格式命名，

此時@RequestBody、@ResponseBody需要與@JsonProperty結合使用，才能做到請求正常解析，響應按要求格式返回。

注意@JsonProperty註解的位置需要加在getter方法上。

如果直接加在屬性上，響應會這樣返回：

{
    "actionStatus": "OK",
    "errorInfo": "success",
    "errorCode": 0,
    "ActionStatus": "OK",
    "ErrorInfo": "success",
    "ErrorCode": 0
}

正常實現的示例代碼如下：

@RequestMapping(value = "/tecentim/v1/callback", method = RequestMethod.POST)
	@ResponseBody
    public CallbackRsp imcallback(
    		@RequestParam String SdkAppid,
    		@RequestParam String CallbackCommand,
    		@RequestParam String contenttype,
    		@RequestParam String ClientIP,
    		@RequestParam String OptPlatform,
			@RequestBody CallbackCommand command) {

		CallbackRsp result = new CallbackRsp();
		result.setActionStatus("OK");
		result.setErrorInfo("success");
		result.setErrorCode(0);
		
		try {
			
			System.out.println("SdkAppid:"+SdkAppid);
			System.out.println("CallbackCommand:"+CallbackCommand);
			System.out.println("contenttype:"+contenttype);
			System.out.println("ClientIP:"+ClientIP);
			System.out.println("OptPlatform:"+OptPlatform);
			System.out.println(command);
			
			
			
		} catch (DingDongFMException de) {
			logger.error("imcallback failed", de);
		} catch (Exception e) {
			logger.error("imcallback failed", e);
		}
		return result;
	}
