Spring3 Js/css/jpg/gif and other static resources cannot be found (no mapping found for HTTP request with URI) problem resolution

Recently used in the project to Spring3, in the exclamation Spring3 annotation configuration is refreshing at the same time unexpectedly appeared this discordant thing, really unbearable

Issue: A similar warning appears when the program loads or is accessed with a browser after the project is deployed, 2011-01-19 10:52:51,646 WARN [Org.springframework.web.servlet.PageNotFound]-<no Mapping found for HTTP request with URI [/sanddemo001/images/1.jpg] in Dispatcherservlet with Name ' Spring ', mainly look at the inside of the angle brackets.

Problem reason: The culprit is the configuration of the Dispatcherservlet request URL mapping for spring under Web. XML, which is configured as follows:

<servlet>
<servlet-name>spring</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>spring</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>

Analysis of the cause:<servlet-mapping> <url-pattern>/</url-pattern> put all the requests to spring to deal with, And all available request URLs are configured in Constroller with annotations like @requestmapping (value = "/login/{user}", Method =requestmethod.get), In this way, access to static resources such as Js/css/jpg/gif will not be available.

Workaround: Add the following configuration in Web. xml

<servlet-mapping>
<servlet-name>default</servlet-name>
<url-pattern>*.css</url-pattern>
</servlet-mapping>

<servlet-mapping>
<servlet-name>default</servlet-name>
<url-pattern>*.gif</url-pattern>

</servlet-mapping>

<servlet-mapping>
<servlet-name>default</servlet-name>
<url-pattern>*.jpg</url-pattern>
</servlet-mapping>

<servlet-mapping>
<servlet-name>default</servlet-name>
<url-pattern>*.js</url-pattern>
</servlet-mapping>

That's OK.

Update: The problem has been re-examined today and a solution has been found.

Workaround 2: Add the following line to the spring configuration file:

<mvc:default-servlet-handler/>

Note that the required version is spring3.0.5 or higher
