Question

在将Spring Boot服务迁移到2.1.3.RELEASE和jdk11之后，发生与hystrix流执行器相关的异常。

例外是ERROR org.apache.catalina.core.ContainerBase.[Tomcat-1].[localhost].[/].[hystrix.stream-actuator-endpoint] - Servlet.service() for servlet [hystrix.stream-actuator-endpoint] in context with path [] threw exception[]

春季启动版本：2.1.3.RELEASE

Java版本：11

所有执行器端点均暴露：management.endpoints.web.exposure.include=*

此外，hystrix.stream端点实际上已启用并提供流。尽管如此，日志中仍然会发生异常

堆栈跟踪：

Answer 1

运行最小配置，我无法重现该问题，我也尝试将版本从2.1.3-RELEASE切换到2.2.2-RELEASE。没问题。因此，我认为您应该在此处提供更多详细信息。在哪里执行您的应用程序？嵌入式tomcat，外部tomcat，docker？请尝试提供更多详细信息。

无论如何，这是我的测试配置。

如果您使用的是Eureka服务器：
Official docs说

删除了Eureka服务器所依赖的JAXB模块 JDK11。如果您打算在运行Eureka服务器时使用JDK 11，则可以必须在您的POM或Gradle文件中包括这些依赖项。
