SpringMVC controller jumps to jsp page css img js and other files do not work and do not display

　　

　　Today, when SpringMVC forwards the page, I find that the jump page is indeed successful, but static resources such as JS and CSS do not work:

 

Control layer code:

    /**
     * Forwarded to the page to view the details of the training program
     * @return
     */
    @RequestMapping("/2TrainSchemeDatail")
    public String forward2TrainSchemeDetail(@RequestParam(defaultValue = "1") String trainSchemeId, Model model){
        model.addAttribute("trainSchemeId",trainSchemeId);
        return "pages/trainingScheme/trainingScheme";
    }

View resolver configuration:

    <!-- 3.视图解释器 -->
    <bean
            class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/" />
        <property name="suffix" value=".jsp" />
    </bean>

 

 

Effect:

 

Finally, after analysis, it is the path problem of JS and CSS: the relative path is used, so the resource cannot be found

 

 

　　

Solution:

• The first

Add in the JSP header

<%
    String path = request.getContextPath();
    String basePath = request.getScheme() + "://"
            + request.getServerName() + ":" + request.getServerPort()
            + path + "/";
%>

 

 Change the relative path of resource files such as css, js, img and access controllers to absolute paths:

 <%=basePath %>js/jquery-1.9.1.min.js

 

 

• • 　　The second　　(recommended)

JSP sets a variable that records the project name:   ${baseurl} is equivalent to /project name as follows

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/fmt" prefix="fmt"%>
<%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions"%>
<c:set var="baseurl" value="${pageContext.request.contextPath}"></c:set>
<script type="text/javascript">
    <%--to record pronect Name (contextPath=/jwxt)--%>
    contextPath = "${pageContext.request.contextPath}";
</script>

 

 

Change the JS and CSS paths to:

    <link rel="stylesheet" href="${baseurl}/css/font.css">
    <link rel="stylesheet" href="${baseurl}/css/xadmin.css">
    <script type="text/javascript" src="${baseurl}/js/jquery.min.js"></script>
    <script type="text/javascript" src="${baseurl}/lib/layui/layui.js" charset="utf-8"></script>
    <script type="text/javascript" src="${baseurl}/js/xadmin.js"></script>
