报错：org.springframework.jmx.export.UnableToRegisterMBeanException: Unable to register MBean [HikariDataSource (null)] with key 'dataSource'; nested exception is javax.management.InstanceAlreadyExistsException: com.zaxxer.hikari:name=dataSource,type=HikariDataSource

 

解决方法：

在application.yml中添加以下内容：

spring:
    jmx:
        default-domain: [application_name]

或者

spring.jmx.enabled=false
