Spring integration Spring集成无法注册TermBeanException:InstanceAlreadyExistsException

当我试图在linux服务器的Tomcat8中部署带有Spring集成的代码时，我得到了InstanceAlreadyExistsException，它有两个独立的流。我参考了几个论坛，仍然无法找到解决方案。但是我在windows平台上测试本地Tomcat8时没有遇到这个异常。欢迎您的任何意见

您没有显示您的

@EnableIntegrationMBeanExport

；如果要部署具有类似流的两个应用程序，则需要将每个应用程序放在不同的域

@enableigrationmbeanexport（defaultDomain=“foo”）

和

@enableigrationmbeanexport（defaultDomain=“bar”）

，因此

org.springframework.integration:type=MessageChannel,name=getCities.channel#0

变成

foo:type=MessageChannel,name=getCities.channel#0

及

如果它只是一个应用程序（看起来像），那么这意味着以前的部署没有正确关闭。

试试这个

<context:mbean-export registration="replaceExisting"/>

---

我在使用抽象基类进行集成测试时遇到了这个错误

---

我将@DirtiesContext添加到我的基类中，以便在每次测试之间刷新应用程序上下文。

您是在FirstConfig还是IntegrationConfig上定义注释？谢谢Gary，我有一个保存注释的AppConfig类（很抱歉，我之前没有共享它）。此类对于两个集成都是通用的。您可以使用属性占位符，例如

defaultDomain=“${managed.domain}”

，并在每个实例中使用不同的属性值。我们有一个好主意。

<context:mbean-export registration="replaceExisting"/>
