Spring 3 mvc:resources causing mvc:interceptors to run multiple times

问题

in Spring 3 MVC dispather-servlet.xml with the configuration below, it seems like everytime a .js file is called the interceptor is kicked off.

<mvc:interceptors>
    <bean class="com.something.SomeInterceptor" />
    </mvc:interceptors>

    <mvc:resources mapping="/js/**" location="/js/" />
    <mvc:resources mapping="/jsp/**" location="/jsp/" />

My view/jsp calls four .js and the interceptor runs four times...

What is the proper way to set up the xml file so that this does not happen?

thanks

回答1:

It's actually the browser that is requesting the JS files, so 4 HTTP requests are being made to your application. You'll need to use the "mapping" element of mvc:interceptor to select a subset of paths that the interceptor will be applied to. For example:

<mvc:interceptors>
  <mvc:interceptor>
    <mapping path="/secure/*"/>
    <bean class="org.example.SecurityInterceptor" />
  </mvc:interceptor>
</mvc:interceptors
