----------------解决方案--------------------------------------------------------
环境变量配错了吧！

----------------解决方案--------------------------------------------------------
重新配制一下！！
----------------解决方案--------------------------------------------------------
你是不是没有添加JDK啊
----------------解决方案--------------------------------------------------------
编码问题
----------------解决方案--------------------------------------------------------
卸载，重新按步骤安装，要先安装完jdk后再安装tomcat
----------------解决方案--------------------------------------------------------
强烈建议你不挂项目，直接启动一下tomcat
----------------解决方案--------------------------------------------------------
你先试试看能不能在浏览器中打开HTTP://LOCALHOST:端口号 这个页面，如果不能重新配置TOMCAT吧
