java - 在dispatcher-servlet.xml中添加了 "mvc:resources"标签来添加js和css，它给出了HTTP Status 404

Question

I am developing a spring-MVC application.It was working fine but as I added "mvc:resources" tag to dispatcher-servlet.xml to add js and css it is giving HTTP Status 404. My dispatcher-servlet.xml is as below:

<?xml  version="1.0" encoding="UTF-8"?>

    <bean id="reportDAO" class="com.asurion.dao.ReportDaoImpl"></bean>

        class="org.springframework.orm.hibernate3.HibernateTransactionManager">
        <property name="sessionFactory" ref="sessionFactory" />
    </bean>

</beans>

And my web.xml is:

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" 
         xmlns="http://java.sun.com/xml/ns/javaee"

         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
             http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
             metadata-complete="true">

  </listener>
  <welcome-file-list>
    <welcome-file>list</welcome-file>
  </welcome-file-list>
</web-app>

The controller code is:

package com.asurion.controller;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.validation.BindingResult;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

import com.asurion.entity.ReportAttr;
import com.asurion.service.ReportManager;

@Controller
public class ReportQueryController {

    @Autowired
    private ReportManager reportManager;

    @RequestMapping(value = "/searchSubmit", method = RequestMethod.POST)
    public String searchSubmit(@ModelAttribute("attributes") ReportAttr attributes, BindingResult result,
            HttpServletRequest request, HttpServletResponse response, Model model) {

        return reportManager.loadReportJson(request, attributes, model);
    }

    @RequestMapping(value = "/search", method = RequestMethod.GET)
    public String searchParams(HttpServletRequest request, Model model) {

        ReportAttr attributes = new ReportAttr();
        model.addAttribute("attributes", attributes);
        return "search";
    }

    @RequestMapping(value = "/list", method = RequestMethod.GET)
    public String listReport(Model map) {
        map.addAttribute("lists", reportManager.getAllRecords());

        return "list";
    }

}

search.jsp is:

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

When I am hitting /search url from mentioned controller, it is giving HTTP Status 404:The requested resource is not available.

Answer 1

我添加了<mvc:annotation-driven/>到我的dispatcher-servlet.xml，它起作用了。
