spring和spring mvc 使用配置----初级配置

      使用spring MVC也就意味着要在java Web项目中进行配置，java Web项目的核心配置文件是web.xml，要使用spring和springMVC框架同样需要在web.xml中进行配置说明，这样才能使spring和springMVC框架在项目中生效。下面进行对配置web.xml、spring-application.xml、spring-mvc.xml三个配置文件进行简单介绍和展示。

一、web.xml

  <?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"     version="2.5">     <!-- spring configuration  begin-->     <context-param>       <param-name>contextConfigLocation</param-name>       <param-value>classpath:spring-application.xml</param-value>     </context-param>          <listener>       <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>     </listener>     <listener>       <listener-class>org.springframework.web.context.request.RequestContextListener</listener-class>     </listener>     <!-- spring configuration end -->          <!-- spring MVC core configuration begin -->     <servlet>       <servlet-name>springMVC</servlet-name>       <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>       <init-param>         <param-name>contextConfigLocation</param-name>         <param-value>classpath:spring-mvc.xml</param-value>             </init-param>       <load-on-startup>1</load-on-startup>     </servlet>     <servlet-mapping>        <servlet-name>springMVC</servlet-name>        <url-pattern>*.xhtml</url-pattern>     </servlet-mapping>     <!-- spring MVC core configuration end -->          <error-page>       <error-code>404</error-code>       <location>/404.xhtml</location>     </error-page>     <error-page>        <error-code>500</error-code>        <location>/500.xhtml</location>     </error-page>     <welcome-file-list>       <welcome-file>/welcome.xhtml</welcome-file>     </welcome-file-list> </web-app>

二、spring-application.xml

<?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:p="http://www.springframework.org/schema/p"     xmlns:context="http://www.springframework.org/schema/context"     xmlns:tx="http://www.springframework.org/schema/tx"     xsi:schemaLocation="http://www.springframework.org/schema/beans        http://www.springframework.org/schema/beans/spring-beans.xsd        http://www.springframework.org/schema/context        http://www.springframework.org/schema/context/spring-context-3.0.xsd        http://www.springframework.org/schema/tx        http://www.springframework.org/schema/tx/spring-tx-3.0.xsd">      </beans>

三、spring-mvc.xml

<?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:p="http://www.springframework.org/schema/p"     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.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.xsd">             <context:component-scan base-package="com.zyiot.controller" />     <!-- configuration view resolver -->     <!-- 注解支持 -->       <!--context:annotation-config/>-->     <!--避免IE执行AJAX时，返回JSON出现下载文件 -->     <bean id="mappingJackson2HttpMessageConverter"         class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">         <property name="supportedMediaTypes">             <list>                 <value>text/html;charset=UTF-8</value>                 <value>text/json;charset=UTF-8</value>                 <value>application/json;charset=UTF-8</value>             </list>         </property>     </bean>     <!-- 采用SpringMVC自带的JSON转换工具，支持@ResponseBody注解 -->     <bean         class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter">         <property name="messageConverters">             <list>                 <ref bean="mappingJackson2HttpMessageConverter" />    <!-- JSON转换器 -->             </list>         </property>     </bean>          <bean         class="org.springframework.web.servlet.view.InternalResourceViewResolver">         <property name="prefix" value="/"></property>         <property name="suffix" value=".jsp"></property>     </bean>     <mvc:annotation-driven />     <mvc:resources location="/" mapping="/**/*.js" />     <mvc:resources location="/" mapping="/**/*.css" />     <mvc:resources location="/" mapping="/**/*.ioc" />     <mvc:resources location="/" mapping="/**/*.svg" />     <mvc:resources location="/" mapping="/**/*.png" />     <mvc:resources location="/" mapping="/**/*.gif" />     <mvc:resources location="/" mapping="/**/*.xml" />     <mvc:interceptors>         <mvc:interceptor>             <!-- 需拦截的地址 -->             <!-- 一级目录 -->             <mvc:mapping path="/*.xhtml" />             <mvc:mapping path="/*.jsp" />                          <!-- 二级目录 -->             <mvc:mapping path="/*/*.xhtml" />             <mvc:mapping path="/*/*.jsp" />             <!-- 需排除拦截的地址 -->             <mvc:exclude-mapping path="/welcome.xhtml" />             <bean class="com.zyiot.interceptor.SystemInterceptor" />         </mvc:interceptor>         <mvc:interceptor>             <mvc:mapping path="/**" />             <bean class="com.zyiot.interceptor.TokenInterceptor" />         </mvc:interceptor>     </mvc:interceptors> </beans>

四、SystemInteceptor.java

package com.zyiot.interceptor; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import org.springframework.web.servlet.HandlerInterceptor; import org.springframework.web.servlet.ModelAndView; public class SystemInterceptor implements HandlerInterceptor{     @Override     public void afterCompletion(HttpServletRequest arg0, HttpServletResponse arg1, Object arg2, Exception arg3)             throws Exception {         // TODO Auto-generated method stub              }     @Override     public void postHandle(HttpServletRequest arg0, HttpServletResponse arg1, Object arg2, ModelAndView arg3)             throws Exception {         // TODO Auto-generated method stub              }     @Override     public boolean preHandle(HttpServletRequest arg0, HttpServletResponse arg1, Object arg2) throws Exception {         return true;     } } 注：需要的Spring jar包
