JSP jsessionid appear in CSS and JS link
By：Roy.LiuLast updated：2019-08-17
In Spring MVC + JSP view page environment.
index.jsp
<html>
<head>
<title>Welcome!</title>
<c:url var="assets" value="/resources/abc" />
<link href="${assets}/css/style.min.css" rel="stylesheet">
<script src="<c:url value="/resources/js/jquery.1.10.2.min.js" />">
</script>
</head>
...
</html>
In the Spring config file, mapped a resource path,
mvc-dispatcher-servlet.xml
<beans ... <context:component-scan base-package="com.mkyong.test" /> <mvc:resources mapping="/resources/**" location="/resources/" /> </beans>
1. Problem
After deployed, Spring MVC can’t get the CSS and JS resource files, and display resources not found error. Review the generated index.jsp page :
index.jsp
<html>
<head>
<title>Welcome!</title>
<link href="/resources/simpliq;jsessionid=2957A...5C8DA/css/style.min.css"
rel="stylesheet">
<script src="/resources/js/jquery.1.10.2.min.js;jsessionid=2957A...5C8DA">
</script>
</head>
...
</html>
The jsessionid is appended as a parameter in the CSS and JS url?
2. Solution
Note
Read this – Under what conditions is a JSESSIONID created?
Read this – Under what conditions is a JSESSIONID created?
To solve this, turn off the page session in JSP page – @page session="true"
index.jsp
<%@page session="true"%>
<html>
<head>
<title>Welcome!</title>
<c:url var="assets" value="/resources/abc" />
<link href="${assets}/css/style.min.css" rel="stylesheet">
<script src="<c:url value="/resources/js/jquery.1.10.2.min.js" />"></script>
</head>
...
</html>
OR use ${pageContext.request.contextPath} , instead of this c:url
index.jsp
<html>
<head>
<title>Welcome!</title>
<link href="${pageContext.request.contextPath}/resources/css/style.min.css"
rel="stylesheet">
<script src="${pageContext.request.contextPath}/resources/js/jquery.1.10.2.min.js" />">
</script>
</head>
...
</html>
