最后，我们把整个项目的截图，代码发一下，大家不想下载那个项目的话，可以在这里看到所有的代码（因为那个项目需要一个下载积分，真不多= =，我觉得我搞了那么久，收点积分应该不过分吧。。。嘿嘿）
这里，我尽量用截图来搞，免得复制粘贴，怪烦的

<!-- Sets the path to the directory where cache .data files are created.
If the path is a Java System Property it is replaced by
its value in the running VM.
The following properties are translated:
user.home - User's home directory
user.dir - User's current working directory
java.io.tmpdir - Default temp file path -->
<!-- 缓存文件存放到硬盘哪里 -->
<diskStore path="G:\Workspaces\MyEclipse Professional 2014\ssh\cacheFile" />
<!--Default Cache configuration. These will applied to caches programmatically created through
the CacheManager.
The following attributes are required for defaultCache:
maxInMemory - Sets the maximum number of objects that will be created in memory
eternal - Sets whether elements are eternal. If eternal, timeouts are ignored and the element
is never expired.
timeToIdleSeconds - Sets the time to idle for an element before it expires. Is only used
if the element is not eternal. Idle time is now - last accessed time
timeToLiveSeconds - Sets the time to live for an element before it expires. Is only used
if the element is not eternal. TTL is now - creation time
overflowToDisk - Sets whether elements can overflow to disk when the in-memory cache
has reached the maxInMemory limit.
-->
<!--
defaultCache节点为缺省的缓存策略
maxElementsInMemory 内存中最大允许存在的对象数量
eternal 设置缓存中的对象是否永远不过期
overflowToDisk 把溢出的对象存放到硬盘上
timeToIdleSeconds 指定缓存对象空闲多长时间就过期,过期的对象会被清除掉
timeToLiveSeconds 指定缓存对象总的存活时间
diskPersistent 当jvm结束是是否持久化对象
diskExpiryThreadIntervalSeconds 指定专门用于清除过期对象的监听线程的轮询时间
-->
<defaultCache
maxElementsInMemory="10000"
eternal="false"
timeToIdleSeconds="120"
timeToLiveSeconds="120"
overflowToDisk="true"
