使用 spring 注释缓存时遇到错误

@Cacheable(key = "#pwId", value = { "pwId" })

应用程序上下文 xsd---->

 xmlns:cache='http://www.springframework.org/schema/cache
 http://www.springframework.org/schema/cache 
        http://www.springframework.org/schema/cache/spring-cache-3.1.xsd

应用上下文

 <cache:annotation-driven/>

<context:component-scan base-package="com.ample.mis"></context:component-scan>

<bean id="cacheManager" class="org.springframework.cache.ehcache.EhCacheCacheManager"
     p:cacheManager-ref="ehcache"/>
 <bean id="ehcache" class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean"
     p:configLocation="WEB-INF/ehcache.xml" 
     p:shared="true"/>

缓存服务类/方法

@Service("programService")
public class ProgramServiceImpl
@Cacheable(key = "#pwId", value = { "pwId" })
public PendingRep editProgram(String pwId) {
    return programDao.editProgram(pwId);
}
}

ehcache.xml

<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xsi:noNamespaceSchemaLocation="http://ehcache.org/ehcache.xsd"> 
<defaultCache
      maxElementsInMemory="1000"  
      eternal="true"  
      overflowToDisk="false" 
      memoryStoreEvictionPolicy="LFU" />

  <cache name="editProgram" 
      maxElementsInMemory="1000"  
      eternal="true" 
      overflowToDisk="false"
      memoryStoreEvictionPolicy="LFU" />

以及得到的错误

SEVERE: java.lang.IllegalArgumentException: Cannot find cache named [pwId] for CacheDefinition[public com.ample.mis.bean.gk.PendingRep com.ample.mis.service.gk.impl.ProgramServiceImpl.editProgram(java.lang.String)] caches=[pwId] | condition='' | key='#pwId'

我在应用程序上下文中使用正确的类（ehcache）吗？请帮助

您"pwId"在注释中用作缓存名称。所以你必须定义一个名为的缓存区域"pwId"，而不是"editProgram".

您在 ehcache.xml 中的缓存区域定义应如下所示：

<cache name="pwId" 
      maxElementsInMemory="1000"  
      eternal="true" 
      overflowToDisk="false"
      memoryStoreEvictionPolicy="LFU" />

尝试

@Cacheable("pwId")

如果您的 xml 配置是：

<cache name="pwId" 
  maxElementsInMemory="1000"  
  eternal="true" 
  overflowToDisk="false"
  memoryStoreEvictionPolicy="LFU" />

尝试

@Cacheable(key = "#a0", value = { "pwId" })

反而

@Cacheable(key = "#pwId", value = { "pwId" })
