现在我知道为什么了，参数种不能有request对象，但我不知道为什么会这样

[sunfeilong]

我用的是 tomcat-embed-core-8.5.31.jar

org.apache.catalina.connector.Request 里面的 getAsyncContext()方法在 asyncContext == null或未开始状态 时会抛出 IllegalStateException 异常。

序列化的时候会调用 getAsyncContext()，可以在序列化的时候加一个 SerializerFeature.IgnoreNonFieldGetter 过滤器。

[freemanyuan]

@sunfeilong 貌似我看了SerializerFeature没有IgnoreNonFieldGetter这个属性

[tanliwei]

切面中获取HttpServletRequest

HttpServletRequest request = ((ServletRequestAttributes)
RequestContextHolder.getRequestAttributes()).getRequest();

[sunfeilong]

@freemanyuan 应该是版本不一样 IgnoreNonFieldGetter是 1.2.7 才加入的。

HttpRequest没有实现序列化

[guozhongdong]

看了半天，不是很明白，报错的主因是因为request没有序列化，还是request没有开启异步模式？
