spring-boot - Tomcat NioEndpoint - 运行套接字处理器时出错

Question

在 Spring Boot 生产应用中，偶尔会抛出以下异常:

o.a.t.u.n.NioEndpoint : Error running socket processor

很难说是什么导致了异常，因为在同一线程之前或之后没有日志。查看堆栈跟踪，它可能发生在到达任何自定义请求预处理代码之前，在 SSL 握手期间，这可能是之前没有日志的原因。 (生产应用程序当前正在登录级别 TRACE。)

可能是什么原因以及如何解决？

Spring Boot 版本:2.2.5.RELEASE

编辑:

我最近遇到了一个非常相似的案例，但是stacktrace却大不相同:

Answer 1

这似乎是由 JRE 问题引起的:

http://hg.openjdk.java.net/jdk/jdk/rev/01d8eae542ff

https://bugs.openjdk.java.net/browse/JDK-8218889

它是固定的

11.0.8 b01

11.0.7 b04

8u261 b05

您使用的是受影响的 JRE 版本吗？

至于你提到的第二个问题:

https://bugs.openjdk.java.net/browse/JDK-8241248

这是一个选项问题(但提到了一种解决方法)。

请研究这两个问题，尝试更新以解决第一个问题，看看您是否可以应用变通方法，只要没有针对第二个问题的修复程序可用。
