jfinal ehcache问题? 400 报错

Jfinal确实很好。 这两天一直在照着demo在搭。 今天想加上ehcache. 以下是相关代码：

控制器：

@Before(CacheInterceptor.class)
	@CacheName("stocklist")
	public void index() {
		setAttr("stockPage", Stock.me.paginate(getParaToInt(0, 1), 5));
		renderJsp("StockIndex.jsp");
	}

<defaultCache
            name ="stocklist"
            maxElementsInMemory="10000"
            eternal="false"
            timeToIdleSeconds="120"
            timeToLiveSeconds="120"
            overflowToDisk="true"
            maxElementsOnDisk="10000000"
            diskPersistent="false"
            diskExpiryThreadIntervalSeconds="120"
            memoryStoreEvictionPolicy="LRU"
            
            />

严重: /stock/
