最近每次启动项目都会抛如下异常:
2018-03-29 09:01:07,831 DEBUG [ehcache] net.sf.ehcache.util.UpdateChecker.checkForUpdate(UpdateChecker.java:107) - Update check failed:

经研究发现,原来是ehcache捣的鬼,每次启动都会访问官方网站查看是否有最新版本,这样也可以统计有多少用户和服务器在使用ehcache。很可能是一个后门程序,默认开启。
找到ehcache.xml文件,ehcache标签中添加属性updateCheck=”false”,如下:
<ehcache name="ehcache" updateCheck="false">
或如下方式修改:
<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="ehcache.xsd" updateCheck="false">
再次重启,问题即可解决。
