博主在开发JavaWeb书城练手项目时遇到注册页面提交后显示500错误和404问题，经过排查发现是缺少jar包导致。修复后虽然能正常跳转，但控制台仍显示'[localhost-startStop-1]'，对此感到困惑。最终确定控制台信息并不影响应用运行，问题得到解决。

Java web书城练手小项目在做注册页面时一直无法正常跳转，明明首页是正常的，一到注册页面提交后就显示500，刷新后显示404

百度了很久都没有找到问题，无奈重敲了一遍发现还是出错。

并且发现控制台也显示tomcat启动失败，就开始思考是不是tomcat的问题导致的，又看了半天百度找解决方案，几乎把下面链接里的解决方案都试了一遍还是不行。
