【问题】
请求报500，一直以为是后台问题
【原因】
前端thymeleaf模板代码没写完整原因（既然用了就要写好格式）
【解决】
将用到thymeleaf标签代码补全，主要原因没用这个@{}补全th:href标签
<a th:href="@{/uploadmoment/mvmain}" title="">首页</a>
ERROR o.a.c.c.C.[.[.[.[dispatcherServlet] - [log,175] - Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception thymeleaf: Could not parse as expression: ""
