使用的 undertow ，经常出现这个错误，一出现就打印很长的日志，一直找不到原因，没找到业务层的代码，求大佬帮忙看看。

这个是节选部分日志，完整的在这里：gitee.com/geekerstar/test/blob/master/sof.txt

一般都是业务代码死递归了…堆栈没了是因为太多次异常 jvm 给吞了

websocket 的好像.
应该是代码有问题.
可能某个异常被递归监听或者处理之类的.

还有自己的堆栈信息别四处乱贴…

看了下原日志, json 解析的 bug 吧.

@Aruforce #3 谢谢，贴之前已经检查了没有敏感信息。应该和 websocket 有关，但是没能定位到业务代码，不知道是不是和 undertow 有关。

@vvtf #2 json 解析的 bug 是指什么呢？框架的问题吗？

明显是业务代码的问题呀，`at io.undertow.websockets.jsr.ServerWebSocketContainer.invokeEndpointMethod(ServerWebSocketContainer.java:612)` 这块调你业务代码的时候递归了，翻一下历史日志，服务器启动之后第一笔这个报错的 StackOverflow 的堆栈会打出来，或者启动的时候加`-XX:-OmitStackTraceInFastThrow`禁用堆栈优化，就可以看见完整堆栈了。

看日志似乎是 json 解析的问题。

可以看下你们的 bean 有没有循环依赖？比如 ClassA 里面有个属性名为 fdParent ，类型也是 ClassA 之类的，然后 json 去序列化这个 class 了。

再比如 ClassA 里面有个属性是 ClassB 类型，ClassB 里面也有个属性是 ClassA 类型之类的。

你有个地方用了 bean copy 或者 json 解析，但是你的 bean 没有 getter 方法，你的堆栈说的是这个错

@litchinn 感谢各位大佬的指导和思路，应该是找到原因了，在 websocket 工具类中存在一个不必要的日志打印，其中将 session 转成 JSON 字符串了，不知道当时为什么这样写。应该就是这个 JSONUtil.toJsonStr(session));导致的，再次感谢各位指点。

```
log.error("[websocket]WebSocket 发生错误，SID 为：{}，错误信息为：{}，session：{}", sid, error.getMessage(), JSONUtil.toJsonStr(session));
```
