如何在Spring MVC中使用静态资源？

Question

How to use static resources in spring mvc? I just want to insert some images in jsp. In which place I must locate my resources? Last time I used to add mvc:recources in servlet-context, but it shows me few errors with mapping.

I'm still in trouble. I've made another question. Please, HALP. https://stackoverflow.com/questions/18020129/troubles-with-static-resources-and-mvcresources

Answer 1

If you are getting 404 error means requested resource is not applicable it means you have mapping error,After this mapping there need to check also controller-servlet.xml mapping also. If you will get error provide your code.

Try this

<servlet>
<servlet-name>app</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>2</load-on-startup>
 </servlet>

<servlet-mapping>
<servlet-name>app</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>

Controller-servlet.xml
<bean id="urlMapping" class="org.springframework.Handler.SimpleHandlerMapping">
<property name="mapping">
<props><prop key="app.do">hello</prop></props></property></bean>

Envious is right , that link contain an example you can see that. By the way , you can modify your code from the below snippet of code
