核心:
这种情况要查看所有的tomcat的日志,才能定位问题.可能是tomcat报错了之类的.
最近在部署一个系统的时候,tomat已经启动成功了,但是通了浏览器访问应用总是报错404.
在本机和远程telnet tomcat的端口都是没有问题的.
就猜想,可能是单单tomcat启动成功了,但是应用没有启动成功.或者说应用关闭了.
在一个类中设置,当bean销毁的时候,打印信息,确实发现日志中出现了bean销毁.
但是单单查看cataline.out日志,没有看到什么错误信息.
于是想到,tomcat还有其他日志,一些其他错误,是不会显示在cataline.out中的,于是去翻看所有的当天日志.发现
localhost.2019-06-10.log中出现异常
java.lang.ClassNotFoundException: com.xxx.portal.evidence.filter.GzipFilter
通过查看,发现是我们的web.xml中需要这个文件,但是新版本早就删除了,于是我们也删除,即可成功启动.
