Spring Boot-多个上下文“在类路径资源中创建名称为'springApplicationAdminRegistrar'的bean时出错”

Question

I have created basic spring boot application for trying out multiple contexts, and here is the source code here

The structure of the application is :

• One main "root" context
• Two children contexts "api" ,"webapp"

The code runs fine, with just one child, the moment i add the "webapp" application context, it gives the below error

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'springApplicationAdminRegistrar' defined in class path resource [org/springframework/boot/autoconfigure/admin/SpringApplicationAdminJmxAutoConfiguration.class]: Invocation of init method failed; nested exception is javax.management.InstanceAlreadyExistsException: org.springframework.boot:type=Admin,name=MultiContextApplication
    at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean(AbstractAutowireCapableBeanFactory.java:1706) ~[spring-beans-5.0.6.RELEASE.jar:5.0.6.RELEASE]
    at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.doCreateBean(AbstractAutowireCapableBeanFactory.java:579) ~[spring-beans-5.0.6.RELEASE.jar:5.0.6.RELEASE]
    at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.createBean(AbstractAutowireCapableBeanFactory.java:501) ~[spring-beans-5.0.6.RELEASE.jar:5.0.6.RELEASE]

Where "MultiContextApplication" is the application jmx-name provided in the application.properties file as

spring.application.admin.jmx-name=org.springframework.boot:type=Admin,name=MultiContextApplication 

Main.java is the main class with @SpringConfiguration annotation.

Can anyone please let me know what could be the issue,

Thanks & Regards, Programmer

This github repository exactly what you want to implement. You should only config jmx for each context.
