带Spring Boot的Ehcache在测试环境中不起作用

Question

pom.xml

<dependency>
            <groupId>net.sf.ehcache</groupId>
            <artifactId>ehcache</artifactId>
</dependency>

在Main类上，增加了以下用于缓存的注释

@EnableCaching
public class Application {

在src/main/resources下，ehcache.xml

<?xml version="1.0" encoding="UTF-8"?>
<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:noNamespaceSchemaLocation="ehcache.xsd"
     updateCheck="true" monitoring="autodetect" dynamicConfig="true">

    <cache name="languageCache" 
      maxEntriesLocalHeap="20"
      overflowToDisk="false"
      eternal="false" 
      diskPersistent="false"
      memoryStoreEvictionPolicy="LRU"/>

     <cache name="countryCache" 
      maxEntriesLocalHeap="280"
      overflowToDisk="false" 
      eternal="false" 
      diskPersistent="false"
      memoryStoreEvictionPolicy="LRU"/>
..

 </ehcache> 

@Configuration
@EnableCaching
public class CacheConfig {

    @Bean
    public CacheManager getEhCacheManager() {
        (new EhCacheCacheManager(getEhCacheFactory().getObject())).getCache("languageCache");
        return new EhCacheCacheManager(getEhCacheFactory().getObject());
    }

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

有什么建议吗，为什么缓存没有被拾取（我缺少一些配置？）在其他环境中？

谢谢。

除非类路径中有许多ehcache.xml，否则它应该可以工作。@enableCaching不会神奇地工作，除非您的类路径中有一个符合JSR107的实现（例如ehcache3)，否则就不会正常工作。

你的代码有效。唯一奇怪的地方是您自己调用getObject()。它仍然有效，但我会这么做的。

@Bean
public CacheManager cacheManager(net.sf.ehcache.CacheManager cacheManager) {
  return new EhCacheCacheManager(cacheManager);
}

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

也就是说，事实上，我会做一些更简单的事情：

@Configuration
@EnableCaching
public class CacheConfig extends CachingConfigurerSupport {

    @Bean
    @Override
    public CacheManager cacheManager() {
        return  new EhCacheCacheManager(new net.sf.ehcache.CacheManager());
    }
}
