was启动突然报错，代码回滚到很久之前也无法解决

今天was启动时，突然报错org.springframework.web.context.ContextLoader] Context initialization failed

怀疑是提交了错误代码导致加载不了spring容器，结果把代码回滚到8月16日了还不行。

这个项目部署在两台服务器上 uat01 和 uat02 前几天uat02一直是不可用的状态，今天看到变成已启动了然后我重新发布项目就报出了这个错，求大神们帮忙解决。

具体错误信息如下

ServerSocketListener那个类报的空指针也是因为去spring容器里去service没取到导致的
