SpringMVC访问静态文件
最近在看SpringMVC的视频，做一下记录。
对于SpringMVC访问静态文件，
首先要配置web.xml文件
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
<display-name>springMVC1</display-name>
<welcome-file-list>
<welcome-file>index.html</welcome-file>
<welcome-file>index.htm</welcome-file>
<welcome-file>index.jsp</welcome-file>
<welcome-file>default.html</welcome-file>
<welcome-file>default.htm</welcome-file>
<welcome-file>default.jsp</welcome-file>
</welcome-file-list>
<!-- springMVC 入口 dispatcher -->
<servlet>
<servlet-name>springMVC</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<!-- 加载配置文件路径 -->
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath*:config/spring-servlet.xml</param-value>
</init-param>
<!-- 何时启动 大于0的值表示容器启动时初始化此servlet，正值越小优先级越高-->
<load-on-startup>1</load-on-startup>
</servlet>
<!-- 拦截 -->
<servlet-mapping>
<servlet-name>springMVC</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>其次，配置spring-servlet.xml文件
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:p="http://www.springframework.org/schema/p"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">
<!-- 路径对应调用的Controller -->
<bean name="/test/helloworld" class="com.tgb.web.controller.HelloWorldController"/>
<!-- 视图解析 -->
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value=http://www.mamicode.com/"/WEB-INF/jsp">>
java代码：
package com.tgb.web.controller;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.multiaction.MultiActionController;
public class StaticController extends MultiActionController{
public ModelAndView img(HttpServletRequest request,HttpServletResponse response){
return new ModelAndView("/staticFile");
}
public ModelAndView add(HttpServletRequest request,HttpServletResponse response){
System.out.println("--------------add---------");
return new ModelAndView("/multi","method","add");
}
public ModelAndView update(HttpServletRequest request,HttpServletResponse response){
System.out.println("--------------update---------");
return new ModelAndView("/multi","method","update");
}
}
package com.tgb.web.controller;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.multiaction.MultiActionController;
public class MultiController extends MultiActionController{
public ModelAndView add(HttpServletRequest request,HttpServletResponse response){
System.out.println("--------------add---------");
return new ModelAndView("/multi","method","add");
}
public ModelAndView update(HttpServletRequest request,HttpServletResponse response){
System.out.println("--------------update---------");
return new ModelAndView("/multi","method","update");
}
}
package com.tgb.web.controller;
import java.util.HashMap;
import java.util.Map;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.Controller;
public class HelloWorldController implements Controller{
public ModelAndView handleRequest(HttpServletRequest arg0,
HttpServletResponse arg1) throws Exception {
// TODO Auto-generated method stub
System.out.println("---------------is here-----------");
String result = "I‘m coming!!";
//return new ModelAndView("/welcome","result",result);//传递字符串参数
Map<String,Object> map = new HashMap<String,Object>();
map.put("1", "sdf");
map.put("2", "234324");
return new ModelAndView("/welcome","map",map);//传递map参数
}
}
JSP页面代码
staticFile.jsp

Spring MVC is coming to see you！！
<br/>
${result }
<br/>
取map值
<div>
<c:forEach items="${map }" var="m">
${m.key } -----> ${m.value }
</c:forEach>
</div>
</body>
</html>
---------------------------------------------------------------------------------------------------------------------------
细节注意点：
1、路径中action的作用和配置，即如何调用方法
2、静态文件放置的位置（注意img文件夹的位置和使用时的配置，不要放在WEB-INF文件夹下tomcat容器会给屏蔽掉）
此文件夹发布到tomcat后的位置
3、使用.do后缀拦截方式
