项目启动之后页面报这个错误


其实有时候我们会有点粗心大意，这个错误其实很简单的，就是我们的MySQL服务没有开启的


具体步骤就是找到控制面板输入：服务












然后再选择：本地服务








然后再：找到MySQL（我这个改了名字所以是MySQL4，大家不必在意），然后启动服务，在重启项目就好了

原因是com.fasterxml.jackson.core:xxxx jar包与项目Spring框架的版本不一致。
解决办法 ：
更改Spring框架版本，或者更改Jackson jar包版本，使其兼容即可解决
例如：
Spring版本：5.0.3.RELEASE 对应 jackson版本：2.9.4
或者
Spring版本：4.1.7.RELEASE 对应 jackson版本：2.5.4

javax.servlet.ServletException: Servlet.init() for servlet dispatcherServlet threw exception


查看有没有缺少包
包出现冲突


由于我的pom文件引入了easyexcel依赖

从而导致了easyexcel的依赖与自己的出现了冲突

所以，建议各位先去仔细检查下pom文件，有没有出现包冲突或者缺少包
