springboot项目报错：org.springframework.jmx.export.UnableToRegisterMBeanException: Unable to register MBean

To avoid this warning consider using the CacheManager factory methods to create a singleton CacheManager or specifying a separate ehcache configuration (ehcache.xml) for each CacheManager instance.

在配置文件中加入：spring.jmx.enabled=false

重新跑项目，解决
