spring static resource with controller requestmapping

I have a spring MVC project: here are my files

web.xml

<servlet>
    <servlet-name>dispatcher</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
</servlet>

<servlet-mapping>
    <servlet-name>dispatcher</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>
<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/applicationContext.xml</param-value>
</context-param>

dispatcher-servlet

<mvc:resources mapping="/resources/**" location="/resources/" />
    <mvc:default-servlet-handler />

    <bean id="viewResolver"
        class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/views/"></property>
        <property name="suffix" value=".jsp"></property>
    </bean>

MainController.java

@Controller
@RequestMapping(value="/test")
public class MainController {

    @RequestMapping(value="/home")
    public ModelAndView home()
    {
        String view="home";
        ModelAndView modelAndView=new ModelAndView(view);
        return modelAndView;
    }

}

home.jsp

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
    <%@ taglib prefix="form" uri="http://www.springframework.org/tags/form"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
    <html>
    <head>

    <link href="resources/css/bootstrap.css" rel="stylesheet" type="text/css" />

    </head></html>

My webaps hosts with URL localhost:8080/projectName/test/home but it doesn't load my static resource i.e. bootstrap.css. it should work because I have put my static resource at proper location webapp/resources/css/bootstrap.css

Q: why my static resource is being routes from controller path.. why its showing 404 not found.?? localhost:8080/projectName/test/resources/css/bootstrap.css

why controller path "test" is appending with URL when spring wants to look-up static resource.

to avoid url problems use JSTL's <c:url tag OR ${pageContext.request.contextPath}

for example in your case:

<link href='<c:url value="/resources/css/bootstrap.css"/>'
      rel="stylesheet" type="text/css" />

OR

<link href='${pageContext.request.contextPath}/resources/css/bootstrap.css'
      rel="stylesheet" type="text/css" />

Note: for first example import JSTL tag library in top of jsp before use. like: 

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>

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

Cuz the configuration of "/resources/" point to the "resources" directory of WebRoot, so the problem becomes clear, just use

<link href="<%= request.getContextPath() %>/resources/css/bootstrap.css" rel="stylesheet" type="text/css" />

to reference the static resources.
Besides, there is also another way to solve this problem, that is to configure the base tag like following,

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%
    String path = request.getContextPath();
    String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<html>
<head>
    <base href="<%=basePath %>">
    <title></title>
    <link href="resources/css/bootstrap.css" rel="stylesheet" type="text/css" />
</head>
....

both will work fine, hope you can help:)

I made it run.. My home.jsp should have to include my static resources like this:

"../" prefix of resources makes controller route to honor static resources.
