如何在Spring Boot中註冊對EhCache的JMX支持？

我正在嘗試爲JMX配置EhCache。看起來我只需要使用EhCacheManager並將其註冊爲mBeanServer。如何在Spring Boot中註冊對EhCache的JMX支持？

這裏是我的CONFIGS：

@Configuration 
public class EhcacheConf { 

    @Bean 
    public CacheManager getEhCacheManager() { 
     return getEhCacheFactory().getObject(); 
    } 

    public EhCacheManagerFactoryBean getEhCacheFactory() { 
     EhCacheManagerFactoryBean factoryBean = new EhCacheManagerFactoryBean(); 
     factoryBean.setConfigLocation(new ClassPathResource("ehcache.xml")); 
     factoryBean.setShared(true); 
     return factoryBean; 
    } 

    @Bean 
    public ManagementService managementService() { 
     return new ManagementService(getEhCacheManager(), 
       mbeanServer(), 
       true, 
       true, 
       true, 
       true, 
       true); 
    } 

    @Bean 
    public MBeanServer mbeanServer() { 
     MBeanServerFactoryBean mBeanServerFactoryBean = new MBeanServerFactoryBean(); 
     mBeanServerFactoryBean.setLocateExistingServerIfPossible(true); 
     return mBeanServerFactoryBean.getObject(); 
    } 

}

application.yaml

spring: 
    datasource: 
     url: "jdbc:h2:file:~/testdb" 
     username: sa 
     password: sa 
     driver-class-name: org.h2.Driver 
    jpa: 
     hibernate: 
     ddl-auto: create-drop 
    cache: 
     type: ehcache 
     ehcache: 
     config: classpath:ehcache.xml 

endpoints: 
    jmx: 
    domain: quiz 
    unique-names: true

ehcache.xml中

<?xml version="1.0" encoding="UTF-8"?> 
<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

有誰知道什麼是錯的？

首先，你並不需要所有的東西配置了Ehcache 2.X和春天開機。您所需要的只是@EnableCaching ehcache依賴關係和您的ehcache.xml配置文件在通常位置。

您的配置也覆蓋了MBeanServer，它關閉了Spring Boot在那裏爲您做的事情。

無論如何，一個樣本總值千字，所以I've created one for you。

編輯：由於Timur Milovanov提到這個示例沒有在關閉時取消註冊MBean，我已經更新了示例以解決此問題。

謝謝你的幫助！樣品真棒！ –

來自Nicoll的示例在上下文停止時不取消註冊mbean。一個靜態方法javadoc：_A一個方便的靜態方法，它創建...這個提供了向後兼容性_ 定義bean並使用'ManagementService'的構造函數可能會更好。在bean定義中，你應該定義init/destroy方法：'@Bean（initMethod =「init」，destroyMethod =「dispose」）'。這個'ManagementService＃dispose'方法從MBeanServer註銷與緩存相關的實例。 PS：如果在沒有容器重啓的情況下在容器（tomcat，jetty）中部署/取消部署應用程序，取消註冊可能很重要 –

非常感謝@TimurMilovanov，我更新了示例。 –
