本文主要是介绍Tomcat报错—Invalid keystore format ，tomcat启动报错，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
今天在修改了一些代码，然后重新放到服务器上，启动服务器的时候报这个错误！我就很纳闷，修改的文件里面根本就没有涉及到tomcat配置文件的内容怎么会出现这样子内容呢？想了很久也网上百度了很多，很多博客提供的解答都没有解决我的问题，然后我们主管过来看了一会，给出了指导性的建议，去看tomcat下的conf/server.xml 文件。然后逐步排查.
贴出错误信息：

解决方案：
1：首先看你的tomcat 下的conf/server.xml 里面文件有没有被改动，我的就是被人改动了，贴出改动的文件信息，可参考：
2：查看项目代码里面是否有不同名称的包名，但是包内有内容相同的文件也会导致启动报错！
我的就是这样子解决的，网上还有其他的解决办法，看你的具体问题，你具体思考一下！希望帮助到大家！
