STS Spring MVC:如何在JSP中包含JS文件 [英] STS Spring MVC: How to include a JS file in a JSP
问题描述
我安装了SpringSource Tool Suite 2.8.0.我正在尝试使用Spring MVC模板作为起点在JSP中包含一个JS文件.我的JSP如下所示:
I installed SpringSource Tool Suite 2.8.0. I'm trying to include a JS file in a JSP, using the Spring MVC template as a starting point. My JSP looks like this:
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ page session="false" %>
<html>
<head>
<title>Home</title>
<script type="text/javascript" src="/a.js"></script>
</head>
<body>
Hello world!
</body>
</html>
a.js位于src \ main \ resources下，看起来像这样:
a.js is under src\main\resources and looks like this:
window.alert("A");
结果就是你好，世界！"在没有警报的情况下被打印:-(
The result is that "Hello world!" gets printed without the alert :-(
我尝试将JS文件放在不同的位置，将src更改为带有/不带有"/"，甚至在web.xml中添加一个servlet映射，以将"* .js"使用默认" servlet.似乎没有任何作用.
I tried putting the JS file in different places, changing the src to be with/without "/", and even adding a servlet-mapping in web.xml to use "default" servlet for "*.js". Nothing seems to work.
我在做什么错了?
推荐答案
.war文件中是否包含js文件?我通常将js和CSS放在src/main/webapp中.诸如src/main/webapp/js和src/main/webapp/css之类.
is the js file getting included in your .war file? I usually put my js and css in src/main/webapp. something like src/main/webapp/js and src/main/webapp/css.
第二，您可以使用c:url适当地引用它，这将确保将应用程序上下文放在那里.
Secondly, you can reference it appropriately using c:url which will take care of putting the app context on there and stuff.
<script type="text/javascript" src="<c:url value="/a.js" />" />
您可以使用firebug或chrome的开发人员工具查看a.js是否获取404，并查看其实际请求的路径.
You can use firebug or chrome's developer tools to see if you are getting a 404 for a.js and see what path it is actually requesting.
