1. In the springmvc framework, importing static resources into the jsp page keeps reporting errors:
jsp page:
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
<img alt="测试" src="<%=basePath%>image/bg.jpg" />
</body>
</html>
警告: No mapping found for HTTP request with URI [/spring10.5/image/bg.jpg] in DispatcherServlet with name 'springMVC'
Solution:
1. <servlet-mapping>
<servlet-name>springMVC</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<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>
Solution 2 : Add the following line to the spring configuration file:
<mvc:default-servlet-handler/>
Note that it needs to be spring3.0.5 or later
Solution 3
<!-- HandlesHTTP GET requests for /resources/** by efficiently serving up static resourcesin the ${webappRoot}/resources directory –>
<mvc:resourcesmapping="/resources/**" location="/resources/" cache-period="31536000"/>
This configuration tells spring how to handle static resources.
Supplementary method: When configuring springmvc: when defining the view resolver, static resources can also be configured together
<!-- Access to static resources (js/image/css) -->
<mvc:resources location="/js/" mapping="/js/**"/>
<mvc:resources location="/image/ " mapping="/image/**"/>
<mvc:resources location="/css/" mapping="/css/**"/>
