<?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" 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>SpringSvcDemo</display-name> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <servlet> <servlet-name>SpringMVC</servlet-name> <servlet-class> org.springframework.web.servlet.DispatcherServlet </servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <!-- 自定義位置 --> <param-value>/WEB-INF/SpringMVC.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>SpringMVC</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> </web-app>
說明:web
<load-on-startup>1</load-on-startup>:是啓動順序,讓這個Servlet隨Servletp容器一塊兒啓動。spring
<servlet-name>SpringMVC</servlet-name>:servlet的名稱。 DispatcherServlet的初始化後,它會在 Web應用程序的WEB - INF文件夾中查找一個文件名[servlet-name]-servlet.xml的配置,這裏將會查找SpringMVC-servlet.xml,假如不想採用默認的方式查找,固然也能夠自定義位置(見web.xml例2)spring-mvc
<url-pattern>*.do</url-pattern>:映射URL模式*. do的DispatcherServlet,Servlet攔截匹配規則能夠自已定義,攔截哪一種URL合適?當映射爲@RequestMapping("/user/add")時,爲例:mvc
WEB-INF/SpringMVC-servlet.xmlapp
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd"> <!-- 自動掃描的包名 --> <context:component-scan base-package="com.test" /> <!-- 默認的註解映射的支持 --> <mvc:annotation-driven /> <!-- 視圖解釋類 --> <bean id="viewResolver" class="org.springframework.web.servlet.view.UrlBasedViewResolver"> <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" /> <property name="prefix" value="/WEB-INF/view/" /> <property name="suffix" value=".jsp" /> </bean> </beans>
在上面的XML配置文件,咱們已經定義了一個標記<context:component-scan>。 這將容許Spring從com.test包中載入全部組件和它的全部子包。 這將載入咱們Controller類。 另外,咱們定義一個bean viewResolver視圖解釋,並添加前綴字符串/WEB-INF/view/以及後綴.JSP。 因此一個爲hello 的@RequestMapping("/hello") 請求映射對應的視圖爲/WEB-INF/jsp/hello.jspjsp
訪問靜態文件(jpg,js,css)的方法:ui
<url-pattern>/</url-pattern>的攔截方法雖然能夠實現REST URL,會致使靜態文件也被攔截,能夠經過配置來設置訪問.

/WEB-INF/view/image/dogs.jpg在視圖hello.jsp中就能夠正常訪問了
