我已将spring（无启动）应用程序升级到java 17和spring 6.1.3，spring集成的版本也从4.1.2.RELEASE升级到6.2.1。我已经成功构建了 jar，但是当我尝试在 tomcat 10 下运行另一个应用程序时，该应用程序使用第一个应用程序作为日志中的依赖项，我发现以下异常：
org.springframework.jmx.export.UnableToRegisterMBeanException: Unable to register MBean [bean 'org.springframework.integration.config.RouterFactoryBean#0'; defined in: 'class path resource [download_datafeed_flow.xml]'; from source: ''int:router''] with key 'org.springframework.integration.config.RouterFactoryBean#0'

在我的第一个应用程序的集成配置中
<int:router>引起：javax.management.InstanceAlreadyExistsException：org.springframework.integration.router：name = org.springframework.integration.config.RouterFactoryBean＃0，type = MethodInvokingRouter
Tomcat 是一个 JVM，整个 JMX 注册表是共享的。所以，当你有同名的 bean 时，它们会发生冲突并出现这样的错误。
解决方案之一是遵循微服务配方，并且不要在同一 JVM 中拥有多个应用程序，或者只是为这些应用程序禁用 JMX：
spring.jmx.enabled = false或者为这些 Spring Integration 组件提供唯一的 id。
