周末在一个现有Spring项目中添加mvc配置,测试一下,发现提示错误:

1
No mapping found for HTTP request with URI [/] in DispatcherServlet with name 'console'

这就奇怪了,配置很简单,就是在web.xml中添加Spring MVC的servlet:

但是就是死活无法访问”/“这个地址。。。。。

最后在stackoverflow上看到了一个回答:

最后一点的意思是,在网站根目录不能有会被认为是默认页面的文件,比如:index.html,index.jsp,default.html等。

难道我中了这一招?一看项目结构,额,原来的项目里在WEB-INF下有一个index.html:

删除这个文件后,就正常啦!

外一则:

1
<mvc:resources mapping="/resources/**" location="/resources/"/>

这个是设置资源文件路由的,一定要记得,location的值,前后都需要有/,才能正确的路由。
