SSM學習-4.配置web.xml

標籤：map   scan   filter   oca   source   -name   location   control   cat   

在web.xml主要配置：

　　1.啟動spring容器

　　2.springmvc的攔截器

　　3.字元編碼過濾器

　　4.REST風格的URI

　　具體配置如下：

<?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">    <!-- 啟動spring容器 -->    <context-param>        <param-name>contextConfigLocation</param-name>        <param-value>classpath:applicationContext.xml</param-value>    </context-param>    <listener>        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>    </listener>    <!-- springmvc的前端控制器  攔截所有請求-->    <servlet>        <servlet-name>dispatcherServlet</servlet-name>        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>        <load-on-startup>1</load-on-startup>    </servlet>    <servlet-mapping>        <servlet-name>dispatcherServlet</servlet-name>        <url-pattern>/</url-pattern>    </servlet-mapping>    <!-- 字元編碼過濾器 -->    <filter>        <filter-name>CharacterEncodingFilter</filter-name>        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>        <init-param>            <param-name>encoding</param-name>            <param-value>utf-8</param-value>        </init-param>        <init-param>            <param-name>forceRequestEncoding</param-name>            <param-value>true</param-value>        </init-param>        <init-param>            <param-name>forceResponseEncoding</param-name>            <param-value>true</param-value>        </init-param>    </filter>    <filter-mapping>        <filter-name>CharacterEncodingFilter</filter-name>        <url-pattern>/*</url-pattern>    </filter-mapping>    <!-- 使用rest風格的URI 將頁面普通的post請求轉換為put或delete請求-->    <filter>        <filter-name>HiddenHttpMethodFilter</filter-name>        <filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class>    </filter>    <filter-mapping>        <filter-name>HiddenHttpMethodFilter</filter-name>        <url-pattern>/*</url-pattern>    </filter-mapping></web-app>

 　dispatcherServlet-servlet.xml配置如下：

<?xml version="1.0" encoding="UTF-8"?>  <beans xmlns="http://www.springframework.org/schema/beans"         xmlns:mvc="http://www.springframework.org/schema/mvc"         xmlns:context="http://www.springframework.org/schema/context"         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-3.1.xsd              http://www.springframework.org/schema/context               http://www.springframework.org/schema/context/spring-context-3.1.xsd              http://www.springframework.org/schema/mvc              http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd">      <!-- springMVC配置 -->    <!-- 掃描配置 -->    <context:component-scan base-package="com.atguigu" use-default-filters="false" >        <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>    </context:component-scan>    <!-- 視圖解析器配置 -->    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">        <property name="prefix" value="/WEB-INF/views/"></property>        <property name="suffix" value=".jsp"></property>    </bean>    <!-- 兩個標準配置 -->    <!-- 將springmvc不能處理的請求交給tomcat -->    <mvc:default-servlet-handler/>    <!-- 能支援springmvc更進階的一些功能，JSR303校正 ajax等 -->    <mvc:annotation-driven/></beans>
