Maven——spring mvc加载js css静态资源文件

之前试过和,都不管用。经过尝试采用了下面的方法，加载成功。

首先是目录结构：

common-js.jsp是我为了避免重复引用静态资源而写的通用的jsp页面。在common-js.jsp中引入静态资源，其他的jsp页面只需要适用引入common-js.jsp即可适用静态资源而不需要在每个jsp页面都重复编写加载静态资源的代码。

下面是common-js.jsp的代码：

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
    
<%
	String contextPath=request.getContextPath();
	//替代 ${pageContext.request.contextPath }写法；
	//js和css是不能放在WEB-INFX下的。否则会访问不到
%>

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>




<%
	String contextPath = request.getContextPath();
%>








    

    	

         	

         		商品管理
         		

	         		
新增商品
	         		
查询商品
	         		
规格参数
	         	
         	
         	

         		网站内容管理
         		

	         		
内容分类管理
	         		
内容管理
	         	
         	
         
    
    

    	

		    

		        	
		    
		
    
    

上面是需要引入common-js.jsp的index.jsp页面的代码。在和标签之间加上这句话：  注意,common-js.jsp是和引入它的jsp放在WEB-INF下的，也必须放在WEB-INF下，否则会加载不到！

放在web-app下加载不到common-js.jsp的错误如下：

因此common-js.jsp必须也放在WEB-INF下。

下面是样式加载成功的效果：
