应用接口使用了`jackson`的`ObjectMapper`,其内部序列化使用了反射机制: ![image](https://user-images.githubusercontent.com/22526463/137422404-0677b9c9-3f07-4fdc-869d-75c8dddd57aa.png) 反射时`jvm`会创建`sun.reflect.DelegatingClassLoader`。 在流量高峰时, ![image](https://user-images.githubusercontent.com/22526463/137422524-b17f64f8-0059-4a83-9e42-9e5873e0bf22.png) ![image](https://user-images.githubusercontent.com/22526463/137422542-8ea986a7-0014-444f-be36-c06e682100d6.png) 大量的`sun.reflect.DelegatingClassLoader`实例涌入, 因为流量较大内存较小流量刚接进来时即发生了`gc`。 ![image](https://user-images.githubusercontent.com/22526463/137422711-629ecaaa-8e09-4806-9bc4-f228cb82c474.png) 因为`gc`会把对象给清理掉,然后`get`方法内的`while`循环一直找不到`eq`的对象,循环出不来, 最终形成了死循环逐渐耗尽`CPU`。 现场最后形成这样的堆栈信息: ![image](https://user-images.githubusercontent.com/22526463/137422818-f1efc9aa-e66e-465a-9016-18cf39d80b51.png)
