Springmvc JS and other files can not find errors, that is, access to static resources __js

When you apply Springmvc, configure URL mappings as follows

<servlet> 
         <servlet-name>appServlet</servlet-name> 
         <servlet-class> org.springframework.web.servlet.dispatcherservlet</servlet-class> 
         <init-param> 
             < Param-name>contextconfiglocation</param-name> 
             <param-value>/web-inf/spring/appservlet/ servlet-context.xml</param-value> 
         </init-param> 
         <load-on-startup>1</ load-on-startup> 
     </servlet> 
  
     <servlet-mapping> 
         <servlet-name>appservlet</ Servlet-name> 
         <url-pattern>/</url-pattern> 
     

will cause the page to reference the JS CSS can not find errors, the following two ways to solve the problem, for reference only:

Method One: Add in Web.xml

<servlet-mapping> <servlet-name>default</servlet-name> <url-pat tern>*.css</url-pattern> </servlet-mapping> <servlet-mapping> <servlet-na 
  
     Me>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>defa ult</servlet-name> <url-pattern>*.js</url-pattern> </servlet-mapping> 

Indicates that no spring filter is used for resource files such as the above
About default is a servlet of Tomcat configuration, "Defaultservlet is defined in $catalina_home/conf/web.xml, and what is defined in the configuration file is loaded at Tomcat startup, is effective for all webapp. Defaultservlet is primarily a directory listing (directory Listing) in Tomcat to indicate that no spring filters are used for resource files such as the above

         <servlet-class>  
           Org.apache.catalina.servlets.DefaultServlet  
         </servlet-class>  
         <init-param>  
             < param-name>debug</param-name>

         </init-param>  
         <init-param>  
             <param-name>listings</param-name>  
             <param-value>true</ param-value>  
         </init-param>  
         <load-on-startup>1</load-on-startup>  
     </ Servlet> ...  
  
     <servlet-mapping>  
         <servlet-name>default</servlet-name>  
         <url-pattern>/</ Url-pattern>  
     

There are some parameters to control the behavior of Defaultservlet. In addition, this defaultservlet is triggered when the requested URL is/is not matched.

Method Two: Use the resources annotation of spring MVC to process static files

Spring MVC's <mvc;resources mapping= "* *" location= "* *" > tags appear in spring3.0.4, mainly for static resource access. Spring has not yet updated its schema when the spring3.0.4 comes out, so it is possible that <mvc:resources > tags are not found in the configuration file, This problem has been solved in the spring3.0.5, and there are many other solutions on the Internet, I do not record here.

First you use spring MVC to configure the servlet that it uses. In Web.xml:

  </servlet>   
  
  <servlet-mapping>   
      <servlet-name>springmvc</ servlet-name>   
      <url-pattern>/</url-pattern>   
 </servlet-mapping>   
 

This will affect the acquisition of static resource files, so you need to have this tag to help you classify the responsibility for obtaining static resources.
So add the following code in the Springmvc-servlet.xml file

<?xml version= "1.0" encoding= "UTF-8"?> <beans xmlns= "Http://www.springframework.org/schema/beans" Xmlns:xsi= "Http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc= "Http://www.springframework.org/schem A/mvc "xsi:schemalocation=" Http://www.springframework.org/schema/beans Http://www.springframework.org/schem A/beans/spring-beans-3.0.xsd Http://www.springframework.org/schema/mvc HTTP://WWW.SPRINGFRAMEWORK.ORG/SC Hema/mvc/spring-mvc-3.0.xsd "> <mvc:resources mapping="/javascript/** "location="/ static_resources/javascript/"/> <mvc:resources mapping="/styles/** "location="/static_resourc   
         es/css/"/> <mvc:resources mapping=/images/**" location= "/static_resources/images/"/> <mvc:default-servlet-handler/> <bean class= "Org.springframework.web.s Ervlet.view.InternalResoUrceviewresolver "> <property name=" prefix "value="/web-inf/views/"/> <property    Name= "suffix" value= ". jsp"/> </bean> </beans>

Here you can see all of my page references to/styles/** resources are searched from inside the/static_resources/css.

Based on the above two methods, you can access the static resources to the site.
