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

Question

所以我的问题是。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指标来检测ehCache，但我不确定如何去做。如果我手动创建缓存实例，那就简单了。您只需使用如下所示的装饰器。但是因为是Spring/Hibernate，我无法控制缓存。你知道我该怎么设置这个吗？

好吧，我相信我终于想通了。事实证明，在Spring JavaConfig for cacheManager中添加返回Spring类ehCacheCacheManager仍然可以用来访问底层的ehCache类并装饰它们。以下是我如何让它工作

@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;
}
