spring mvc怎么修改mapping匹配顺序

正常情况下 访问一个a.jpg 图片文件时，先通过DefaultAnnotationHandlerMapping 来找control ，control没有这个action ，然后Order升序后从SimpleUrlHandlerMapping里匹配。 我想先走SimpleUrlHandlerMapping里去匹配再去DefaultAnnotationHandlerMapping里去匹配，应该怎么写，最好有实际代码。谢谢各位大佬

你是用这个通配Action实现restful的吗，如果是，在这个action中放行才行

springmvc.xml中配置加入
mvc:default-servlet-handler/

<mvc:resources mapping="/static/**"
    location="/static/" cache-period="31536000" />

    <!-- 对静态资源文件的访问， 将无法mapping到Controller的path交给default servlet handler处理 -->
<mvc:default-servlet-handler />

你这个情况可能是缺了第一个配置，将你静态资源的url路径和本地文件路径配置下

在服务端添加个请求跳转不就行了
