如何在Spring Boot应用程序中为ehCache配置Dropwizard/CodaHale指标？

Question

所以这是我的问题.我的Spring Boot应用程序使用Hibernate/JPA和ehCache进行二级缓存.我想用Dropwizard/Coda-Hale指标来测试ehCache,但我不确定如何做到这一点.如果我手动创建Cache实例,那么它很简单.你只需使用这里显示的装饰器.但由于它是Spring/Hibernate,我无法控制缓存.有什么想法我会如何设置它？

好吧,我相信我终于明白了.事实证明,为返回Spring类ehCacheCacheManager的cacheManager添加Spring JavaConfig仍然可以用来访问底层的ehCache类并装饰它们.以下是我如何使用它

@Bean
public EhCacheCacheManager ehCacheCacheManager() {
    final EhCacheCacheManager ehCacheCacheManager = new EhCacheCacheManager(ehCacheManagerFactoryBean().getObject());
    net.sf.ehcache.CacheManager cacheManager = ehCacheCacheManager.getCacheManager();
    String[] cacheNames = cacheManager.getCacheNames();
    for (String cacheName : cacheNames) {
        Cache cache = cacheManager.getCache(cacheName);
        cacheManager.replaceCacheWithDecoratedCache(cache, InstrumentedEhcache.instrument(metricRegistry, cache));
    }
    return ehCacheCacheManager;
}


@Bean
public EhCacheManagerFactoryBean ehCacheManagerFactoryBean() {

    EhCacheManagerFactoryBean cacheManagerFactoryBean = new EhCacheManagerFactoryBean();

    cacheManagerFactoryBean.setConfigLocation(new ClassPathResource("ehcache.xml"));
    cacheManagerFactoryBean.setShared(true);

    return cacheManagerFactoryBean;
}
