在jeecms v5中采用缓存管理回话的方式，这里采用最简单的ehcache实现回话的管理。

具体实现如下：

Ehcache的配置：

overflowToDisk="true"diskSpoolBufferSizeMB="30"maxElementsOnDisk="10000000"

diskPersistent="false"diskExpiryThreadIntervalSeconds="120"/>

Spring的配置

xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd"

default-lazy-init="true">
