SpringMVC异常_Could not resolve view with name 'javascripts/jquery-2.1.4' in servlet with name

Posted 2020-06-21

    今天在编写代码的时候，自己页面中的按钮都无法点击，CSS样式也无法加载出来，查看之前的Spring MVC 的配置文件也是都正常，查看后台，发现如下错误

严重: Servlet.service() for servlet [springMVC] in context with path [/spring-idap-web] threw exception [Could not resolve view with name ‘javascripts/jquery-2.1.4‘ in servlet with name ‘springMVC‘] with root cause
javax.servlet.ServletException: Could not resolve view with name ‘javascripts/jquery-2.1.4‘ in servlet with name ‘springMVC‘

后来百度了老半天，什么也没有发现，重新启动MyEclipse，tomcat，甚至机器都重新启动了一遍还是不行。有时候感觉很二啊，感觉出错了重启就好了。。之后逐行比对SVN资源库上的代码，最终终于找到问题的原因

    @RequestMapping//问题的原因
    public ModelAndView  showHomePage()
    {
        ModelAndView model = new ModelAndView();
        return model;
    }

其实是在编写Controller的时候，其中的某个方法没有映射到具体的URL地址。所以导致最终出错。解决办法就是为@RequestMapping添加一个URL地址就好了。
