jsp中video mp3 mp4不能播放

本人用的springmvc 拦截了 video  mp3 mp4

静态资源访问放行就好了。

	<!-- 静态资源访问 -->
	<mvc:resources location="/img/" mapping="/img/**" />
	<mvc:resources location="/js/" mapping="/js/**" />
	<mvc:resources location="/css/" mapping="/css/**" />
	<mvc:resources location="/mp3/" mapping="/mp3/**" />
	<mvc:resources location="/video/" mapping="/video/**" />
	<mvc:resources location="/article/" mapping="/article/**" />

        <div class="video-group">
          <video width="300" height="300" controls poster="${prc}/img/666.jpg">
              <source src="${prc}/video/aa.mp4" type="video/mp4"> 
          </video>
        </div>
