在Spring Boot应用程序中刷新Spring ApplicationContext时获取异常 [英] Getting exception while refreshing Spring ApplicationContext in Spring Boot application

问题描述

我们正在将Spring Boot用于我们的应用程序. 启动应用程序后，在运行时中，我们将一个新Bean添加(加载)到现有ApplicationContext中.

We are using Spring Boot for our application. After starting the application, in the runtime we are adding(loading) a new Bean to the existing Applicationcontext.

AnnotationConfigApplicationContext appContext = new AnnotationConfigApplicationContext();
appContext.register(NewBean.class);
appContext.refresh();

添加bean之后，我们正在刷新applicationContext

after adding the bean we are doing a refresh of applicationContext

在刷新期间，MBean尝试重新注册一些端点，并且我们收到以下错误 (在所有这些端点上都出错-requestMappingEndpoint，environmentEndpoint，healthEndpoint，beansEndpoint，infoEndpoint，metricsEndpoint，traceEndpoint，dumpEndpoint， autoConfigurationAuditEndpoint，shutdownEndpoint，configurationPropertiesReportEndpoint)

During the refresh the MBean is trying to reregister some endpoints and we are getting the following error (getting error for all these endpoints - requestMappingEndpoint, environmentEndpoint, healthEndpoint, beansEndpoint, infoEndpoint, metricsEndpoint, traceEndpoint, dumpEndpoint, autoConfigurationAuditEndpoint, shutdownEndpoint, configurationPropertiesReportEndpoint)

Caused by: javax.management.InstanceAlreadyExistsException: org.springframework.boot:type=Endpoint,name=configurationPropertiesReportEndpoint

        at org.springframework.jmx.export.MBeanExporter.registerBeanNameOrInstance(MBeanExporter.java:605)

任何人都可以告诉我如何跳过此异常吗?

Can anyone please tell how to skip this exception?

我也尝试了以下方法

@EnableIntegrationMBeanExport(registration = RegistrationPolicy.REPLACE_EXISTING)

但出现以下异常

Caused by: org.springframework.jmx.export.UnableToRegisterMBeanException: Unable to register MBean [org.springframework.integration.monitor.IntegrationMBeanExporter@16c5464] with key 'integrationMbeanExporter'; nested exception is javax.management.InstanceAlreadyExistsException: org.springframework.integration.monitor:name=integrationMbeanExporter,type=IntegrationMBeanExporter

推荐答案

某些applicationContext可以刷新时间，但不能刷新时间AnnotationConfigApplicationContext. 当构造运行刷新方法的AnnotationConfigApplicationContext时，将报告此异常，您可以先销毁它，然后刷新

Some applicationContext can refresh times, but not AnnotationConfigApplicationContext. when you construct AnnotationConfigApplicationContext, which had run the refresh method, so it will be reported exception, you can destroy it first, and then refresh
