Spring Ehcache不被使用

Question

I'm trying to setup a simple Spring cache ehcache for my MVC page. But it seems that the cache is never used. My function is executed each time.

@Cacheable(value="newsDocuments",key="#category")
public List<ProcessedDocument> getDocuments(String category, int   limit){
    List<ProcessedDocument> list = new ArrayList<ProcessedDocument>();
    System.out.println("getDocumetns!" + DateTime.now());
    list = getDBStuff(category,limit);
    return list;
}

ehcache.xml

<?xml version="1.0" encoding="UTF-8"?>
<ehcache>
    <diskStore path="java.io.tmpdir" />
    <defaultCache maxElementsInMemory="100" eternal="false"
              timeToIdleSeconds="10000" timeToLiveSeconds="60000"   overflowToDisk="false" />
    <cache name="newsDocuments" timeToIdleSeconds="10000" timeToLiveSeconds="60000" maxElementsInMemory="10" eternal="false"    overflowToDisk="false" />
</ehcache>

spring config file

    @DynamoDBTable(tableName="ProcessedDocuments")
public class ProcessedDocument implements Serializable {
//Just contains some simple get and set methods.
}

Each time getDocuments is being executed, it calls the db and outputs a new "getDocumetns!" + DateTime.now() in the console.

The only "strange" I see in the debug is

DEBUG: net.sf.ehcache.config.ConfigurationHelper - CacheDecoratorFactory not configured. Skipping for 'newsDocuments'.
DEBUG: net.sf.ehcache.config.ConfigurationHelper - CacheDecoratorFactory not configured for defaultCache. Skipping for 'newsDocuments'.
INFO : org.springframework.web.servlet.DispatcherServlet - FrameworkServlet 'mvc-dispatcher': initialization completed in 875 ms

Am I missing something every basic here?

I looked for you and googled it .I found an example from Mkyong Ehcache example ;

http://www.mkyong.com/spring/spring-caching-and-ehcache-example/

and I think it will useful for you. Because your ehcache.xml: not similar Mkyong's example ehcache.xml.

I hope it will be useful for you..
