bean中属性名和json不一致解决方案（请求和响应）

 

此时@RequestBody、@ResponseBody需要与@JsonProperty结合使用，才能做到请求正常解析，响应按要求格式返回。

注意@JsonProperty注解的位置需要加在getter方法上。

如果直接加在属性上，响应会这样返回：

{
    "actionStatus": "OK",
    "errorInfo": "success",
    "errorCode": 0,
    "ActionStatus": "OK",
    "ErrorInfo": "success",
    "ErrorCode": 0
}
正常实现的示例代码如下：

@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;
    }
