一. 問題及需求

　　因爲Spring MVC的web.xml文件中關於DispatcherServlet攔截url的配置爲"/"，攔截了全部的請求，同時*.js，*.jpg等靜態資源也被攔截了，致使運行時跳轉後的頁面沒法加載圖片資源，以下圖所示。css

web.xml：html

1     <!-- 配置DispatcherServlet所要攔截的url -->
2     <servlet-mapping>
3         <servlet-name>springmvc</servlet-name>
4         <url-pattern>/</url-pattern>
5     </servlet-mapping>

loginSucc.jsp：java

 1 <%@ page language="java" contentType="text/html; charset=UTF-8"
 2  pageEncoding="UTF-8"%>
 3 <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
 4 <html>
 5 <head>
 6 <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
 7 <title>Spring MVC歡迎頁面</title>
 8 </head>
 9 <body>
10 返回信息:${msg} 11 <!-- 靜態資源jpg -->
12 <img alt="靜態資源圖片" src="../image/20160726.jpg">
13 </body>
14 </html>

　　需求：正常加載出圖片資源。web

二. 解決方案

　　只須要修改springmvc.xml： spring

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <beans xmlns="http://www.springframework.org/schema/beans"
 3  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 4  xmlns:mvc="http://www.springframework.org/schema/mvc"
 5  xmlns:p="http://www.springframework.org/schema/p"
 6  xmlns:context="http://www.springframework.org/schema/context"
 7  xmlns:aop="http://www.springframework.org/schema/aop"
 8  xmlns:tx="http://www.springframework.org/schema/tx"

21     
22     <!-- 自動註冊組件 -->
23     <mvc:annotation-driven/>
24     
25     <!-- 經過掃描將帶有@Controller註解的類交由spring容器管理並維護 -->
26     <context:component-scan base-package="com.pers"/>
27 
28     <!-- 配置視圖解析器 若是不配置ViewResolver,Spring MVC默認使用org.springframework.web.servlet.view.InternalResourceViewResolver做爲 29  ViewResolver,並且prefix和suffix都爲空 -->
30     <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
31         <property name="prefix" value="/WEB-INF/jsp/"></property>
32         <property name="suffix" value=".jsp"></property>
33     </bean>
34     
35     <!-- 訪問靜態資源 -->
36     <mvc:resources location="/image" mapping="/**"/>
37     
38 </beans>
