问题spring-cloud-config和spring-cloud-bus

Question

我有三个应用程序，一个是spring-cloud-config服务器点，其他是spring-cloud-config客户端点。我在彼此中配置了spring-cloud-bus，以使我的客户端点自动刷新发生变化，但在我的应用程序运行时，我得到了一个异常，如下所示

    c.netflix.discovery.TimedSupervisorTask  : task supervisor rejected the task

java.util.concurrent.RejectedExecutionException: Task java.util.concurrent.FutureTask@17834c50 rejected from java.util.concurrent.ThreadPoolExecutor@1944b0d0[Terminated, pool size = 0, active threads = 0, queued tasks = 0, completed tasks = 0]

这是我的spring-cloud-server配置

#git config
spring.cloud.config.server.git.uri = ###
spring.cloud.config.server.git.username=###
spring.cloud.config.server.git.password=###
spring.cloud.config.server.git.search-paths = puhui-cloud-config-client

#spring.active.profile
spring.profiles.active=dev

#spring-cloud-bus-amqp config
spring.rabbitmq.host=localhost
spring.rabbitmq.port=5672
spring.rabbitmq.virtual-host=/

这是我的spring-cloud-config服务器pom

此异常不会影响操作的应用程序，但我想知道应用程序抛出此异常的原因

Answer 1

尝试在发现服务器中为客户端启用注册和获取注册表

eureka.client.registerWithEureka=true

eureka.client.fetchRegistry=true

Answer 2

这是Eureka本身的问题，请尝试升级您正在使用的eureka版本。您可以查看此https://github.com/spring-cloud/spring-cloud-netflix/issues/2228

Answer 3

我认为错误日志与Eureka有关。您运行的是Eureka服务器吗？您已经在pom文件中添加了Eureka依赖项，但我在您的属性文件中看不到任何与Eureka相关的配置。尝试不使用这些依赖项，或者构建一个Eureka服务器并使用它们运行。或者至少在配置文件中添加以下属性。

eureka.client.enabled=false
