[SPRING] BeanCreationException : 'springApplicationAdminRegistrar'라는 이름의 빈을 만드는 동안 오류가 발생했습니다. InstanceAlreadyExistsException

BeanCreationException : 'springApplicationAdminRegistrar'라는 이름의 빈을 만드는 동안 오류가 발생했습니다. InstanceAlreadyExistsException

저는 2 개의 스프링 부트 응용 프로그램을 가지고 있습니다.

application_A dependsn_on application_B

실제로 각 응용 프로그램에는 @SpringBootApplication으로 표시된 주 클래스가 있습니다.

application_B는 시작되었지만 application_A가 시작되지 않습니다.

디버그에서 나는 spring이 시작하는 동안 org.springframework.boot.autoconfigure.admin.SpringApplicationAdminJmxAutoConfiguration # springApplicationAdminRegistrar를 두 번 실행하여 실패하는 것을 봅니다.

나는 속성을 설정하려고 :

 spring.application.admin.enabled=false

그러나 그것은 나를 돕지 않습니다.

이 예외는 어떻게 피할 수 있습니까?

나는 이것 하나를 찾았습니다 https://github.com/spring-projects/spring-boot/issues/6378 그러나 해결책은 없습니다

해결법

1. ==============================

   1.SpringApplicationAdminJmxAutoConfiguration에는 다음과 같은 코드가 있습니다.

   SpringApplicationAdminJmxAutoConfiguration에는 다음과 같은 코드가 있습니다.

   String jmxName = this.environment.getProperty(JMX_NAME_PROPERTY,
               DEFAULT_JMX_NAME);
       if (this.mbeanExporters != null) { // Make sure to not register that MBean twice
           for (MBeanExporter mbeanExporter : this.mbeanExporters) {
               mbeanExporter.addExcludedBean(jmxName);
           }
       }
       return new SpringApplicationAdminMXBeanRegistrar(jmxName);
   

   우리가 상수를 가지고있는 곳 :

   /**
    * The property to use to customize the {@code ObjectName} of the application admin
    * mbean.
    */
   private static final String JMX_NAME_PROPERTY = "spring.application.admin.jmx-name";
   
   /**
    * The default {@code ObjectName} of the application admin mbean.
    */
   private static final String DEFAULT_JMX_NAME = "org.springframework.boot:type=Admin,name=SpringApplication";
   

   따라서 jmx-name을 각 응용 프로그램마다 고유 한 것으로 간주해야합니다. spring.application.admin.jmx-name 구성 속성을 지정해야한다는 뜻입니다.
