gdouyang opened a new issue #1031: 关于jackson自定Serializer中调用ContextUtils.getInvocationContext()返回null问题
URL: https://github.com/apache/servicecomb-java-chassis/issues/1031
 
 
   请问目前我有一个场景需要根据当前语言对字段做国际化，在自定义Serializer中调用ContextUtils.getInvocationContext()来获取里面所存放的语言，但这个一直返回null,跟踪调用发现使用了SwaggerProducerOperation#syncInvoke这个方法，在Controller返回结束时将removeInvocationContext，这个是不是可以跟completableFutureInvoke方法一样把ContextUtils.removeInvocationContext();放到最后一行？
   ```
     public void completableFutureInvoke(SwaggerInvocation invocation, AsyncResponse asyncResp) {
       ContextUtils.setInvocationContext(invocation);
       doCompletableFutureInvoke(invocation, asyncResp);
       ContextUtils.removeInvocationContext();
     }
   
     public void syncInvoke(SwaggerInvocation invocation, AsyncResponse asyncResp) {
       ContextUtils.setInvocationContext(invocation);
       Response response = doInvoke(invocation);
       ContextUtils.removeInvocationContext();
       asyncResp.handle(response);// 这个是不是可以向上移动一行
     }
   ```
