回答1:

I think you should put ${pageContext.servletContext.contextPath} and you should notice the name (and version ) declare in Spring-dispatcher-servlet.xml must same with the file in /js directory (jquery-1.6.2.js,jquery-1.11.1.js, jquery.js v.v...)

<script type="text/javascript" src="${pageContext.servletContext.contextPath}/js/jquery-1.6.2.js"></script>

and as everyone suggest, make sure you have

<mvc:resources mapping="/js/**" location="/js/" />

in Spring-dispatcher-servlet.xml

hope it work

回答2:

Its not a very much spring way, but I could link a javascript file as below

<script type="text/javascript" src="/js/jquery-1.11.1.js" ></script>

Please check if it works for you also.!
