微信获取签名token

因为token是有时间限制的，所以要用调度让调度框架每隔多长时间去访问一次，获得tokan

quartz是一个开源的作业调度框架，它完全由Java写成，并设计用于J2SE和J2EE应用中。它提供了巨大的灵活性而不牺牲简单性。你能够用它来为执行一个作业而创建简单的或复杂的调度。本系统结合通过Spring来集成Quartz。
Quartz 下载地址：

          http://grepcode.com/snapshot/repo1.maven.org/maven2/org.quartz-scheduler/quartz/1.7.3

首先下载包：quartz-1.7.3.jar

需要用到的jar包
json相关 spring相关 Struts相关 Log相关

把包放到 lib 里面。
当然需要把applicationContext-quartz.xml 文件添加到 <import resource="classpath:applicationContext-quartz.xml" />
