我是 ehcache 和 spring 注释集成的新手。我在spring 2.5中使用com.googlecode.ehcache.annotations.Cacheable注释，如下所示，它从不缓存返回值。返回一个空列表，并且每次控制器进行调用时都会调用该方法。请帮帮我。cache.getKeys()

下面的方法是一个接口的实现，控制器根据映射 jsp 的请求调用该接口URL.cacheID始终是常量，我的想法是将检索到的值存储在 hashmap 中，并在应用程序需要时访问这些映射。

 @Override
 @Cacheable(cacheName="partnerMapping")
 public String retrievePartnerMappings(String cacheID) {
   partnerCodeToNameMapping = new HashMap<String, String>();
   partnerNameToCodeMapping = new HashMap<String, String>();
   Cache cache = cacheManager.getCache("partnerMapping");
   log.debug(cache.getKeys().toString());
   try {
   log.debug("Querying for partner mappings...");
   Collection<PartnerMapping> partnerMappings = this.getSimpleJdbcTemplate()
      .query(
          sqlStatements.getProperty("selectAllSql"),
          ParameterizedBeanPropertyRowMapper
              .newInstance(PartnerMapping.class));
   for (PartnerMapping mapping : partnerMappings) {
     partnerCodeToNameMapping.put(mapping.getPartnerCode().toUpperCase(),
        mapping.getPartnerName());
     partnerNameToCodeMapping.put(mapping.getPartnerName(), mapping
        .getPartnerCode().toUpperCase());
   }
   return "success";
 } catch (DataAccessException e) {
  log.error("Unable to retrieve the partner mappings!!", e);
  return "fail";
 }
}

ehCache.xml：

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

<cache name="partnerMapping" maxElementsInMemory="100" eternal="false"
   overflowToDisk="false" timeToLiveSeconds="120" timeToIdleSeconds="120"/>
</ehcache>

设法得到这个工作。我在主 dispatcherServlet xml 中包含了 ehcache 配置，而不是单独的 xml 配置，然后包含在 spring 上下文中。
