我的tomcat服务器突然出现了问题，怎么也无法启动，空服务器可以启动，但是带着项目就不行
问题描述：
首先的消息框是这个：Server Tomcat v8.0 Server at localhost failed to start.
我以前一直是能用的，我之前修改了下Java的路径，后来又有一个叫maven的一堆文件，我删除过整个文件，后来是它自己下载的，我试过重新安装tomcat，但是没有用，xml文件我也不太懂，试过几次都不行，我还把workspace里的除了项目之外的文件都删除过，但是让然没用，能帮我看看咋整吗

答
看报错java环境变量有问题，jdk路径不对，你是不是删了不该删的。重新配置下java环境，然后把你的项目clean下。再放进tomcat中。
答
E:\Program Files (x86)\java\jdk1.8.0_161\bin
看下 这个目录
日志报的是这个目录不存在
如果真的不存在
环境变量改一下就好了。
具体操作如下：
win10 环境
右击 此电脑（我的电脑） 点击 属性
点击 高级系统设置
点击环境变量
在下方 系统变量 中
找到 变量名 为 JAVA_HIME 的 那条数据
选中编辑成 正确的即可
