Detailed introduction to Spring MVC accessing static files

This article mainly introduces the relevant information of Spring MVC to access static files in detail. It has certain reference value. Interested friends can refer to

How to intercept "*. For URLs with a suffix like "do", there is no problem of not being able to access static resources.

If your DispatcherServlet intercepts "/" and intercepts all requests in order to implement REST style, then access to static files such as *.js and *.jpg will also be intercepted.

We need to solve this problem.

Purpose: Static files can be accessed normally, and 404 cannot be reported when static files cannot be found.

Option 1: Activate Tomcat's defaultServlet to process static files

Xml code

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

To configure multiple, configure one for each file

To be written in front of DispatcherServlet, let defaultServlet intercept the request first, so that the request will not enter Spring, I want performance It's the best.

The name of the default Servlet that comes with Tomcat, Jetty, JBoss, and GlassFish -- "default"
The name of the default Servlet that comes with Google App Engine -- "_ah_default"
Comes with Resin The name of the default Servlet -- "resin-file"
WebLogic The name of the default Servlet that comes with it -- "FileServlet"
WebSphere The name of the default Servlet that comes with it -- "SimpleFileServlet"

Option 2: In spring3.0.4 and later versions, mvc:resources is provided. How to use:
