java - war包放到tomcat,日志报404
本文介绍了java - war包放到tomcat,日志报404的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
问 题
安装RAP， 将war 包放webapp 里面，页面访问空白，日志报404。???
这是webapps里的文件 ROOT 是由ROOT.war生成的
这是ROOT里的文件
有个疑问，为什么JRE_HOME的路径不对，是不是这个问题？
访问页面的日志信息
刚接触tomcat,请问有知道是什么原因造成的吗?
访问tomcat的默认页面是可以访问的，自己放入war包就有问题。
谢谢~
这是执行./catalina.sh run 报的信息。

解决方案
不要用 startup.sh 启动 tomcat，因为项目启动出错不能及时看到。
在 bin 目录有一个 catalina.sh 文件，执行它:
./catalina.sh run然后 tomcat 进程会在前台启动，可以直接看到输出（不需要看日志文件了）。
404 很可能是项目启动失败了（例如 Servlet、Spring 配置错误之类的） 。
你按照上面做了以后，贴出启动日志。
这篇关于java - war包放到tomcat,日志报404的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
