我在尝试在Linux服务器的tomcat 8中部署Spring集成的代码时收到InstanceAlreadyExistsException,其中包含2个独立的流。我提到了几个论坛,但仍然无法找到解决方案。但是在我的本地tomcat 8在windows平台上进行测试时没有得到这个异常。任何输入赞赏。Spring-Integration UnableToRegisterMBeanException:InstanceAlreadyExistsException

的配置将被下面 -

@EnableAspectJAutoProxy
@EnableAsync
@EnableWebMvc
@ComponentScan(basePackages = "foobar")

@Bean
@Scope(BeanScopes.SINGLETON)

return LoggerFactory.getLogger("SampleService");
}
@Bean

}
}
@EnableIntegration

您是在FirstConfig还是IntegrationConfig上定义了注释? – ydd1987
感谢加里,我有我的AppConfig类,它包含注释(抱歉,我没有先前分享它)。这个类对于这两个集成都很常见。 –
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[测试用例可以这样做](https://github.com/spring-projects/spring-integration/blob/master/spring-integration-jmx/src/test/java/org/springframework/integration/jmx /configuration/EnableMBeanExportTests.java#L123)。 –
