spring + springMVC集成

感叹下，不知道是老了还是怎么了，学了的东西，不过多久就忘了，要么就是没有完全掌握啊。

进入正题，今天搞定下怎么集成spring、springMVC。

1. jar包挺简单的，把所有的spring框架的jar包全放到lib目录下就OK了。spring 、 springMVC是一家的，挺方便的。

2.关键是配置文件：

(1) web.xml文件配置如下：

<?xml version="1.0" encoding="UTF-8"?><web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">  <display-name></display-name>  <welcome-file-list>    <welcome-file>index.jsp</welcome-file>  </welcome-file-list>    <!-- spring配置文件的路径 -->  <context-param><!-- 最先启动 -->  <param-name>contextConfigLocation</param-name>  <param-value>classpath*:config/applicationContext.xml</param-value>  </context-param>    <listener> <!--加载spring配置文件  -->  <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>  </listener>        <!-- 配置springMVC -->  <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*:config/springMVC-servlet.xml</param-value> <!--springMVC-servlet.xml文件位置 -->  </init-param>    <load-on-startup>1</load-on-startup>  <!-- 设置启动顺序，1为最高 -->  </servlet>    <servlet-mapping>  <servlet-name>springMVC</servlet-name>  <url-pattern>/</url-pattern>  <!-- 配置成/*出错 -->  </servlet-mapping>       <!-- 编码相关 -->  <filter>      <filter-name>encodingFilter</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>forceEncoding</param-name>        <param-value>true</param-value>      </init-param>    </filter>    <filter-mapping>      <filter-name>encodingFilter</filter-name>      <url-pattern>/*</url-pattern>    </filter-mapping>    </web-app>

注：启动顺序是：

<context-param/>

<listener/>

       <filter/>

       <servlet/>

(2) springMVC-servlet.xml配置文件，和原来没有变化，再记录下，如下：

<?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:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context"xmlns:util="http://www.springframework.org/schema/util"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-3.0.xsd              http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd              http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.0.xsd"><bean id="viewResolver"class="org.springframework.web.servlet.view.InternalResourceViewResolver"><property name="prefix" value="/" />  <!--   <property name="prefix" value="/WEB-INF/jsp/" /> 更安全--><property name="suffix" value=".jsp" /></bean><!-- 注解扫描包 --><context:component-scan base-package="com.study.controller.annotation"></context:component-scan><!-- 开启注解 --><mvc:annotation-driven/>  <!-- 3.0版本后才有 --> <!-- 静态资源，表明不会经过过滤器 --><mvc:resources location="/img/" mapping="/img/**"/> <!-- 对img文件夹下的所有文件 --><mvc:resources location="/js/" mapping="/js/**"/> <!-- 对img文件夹下的所有文件 -->  <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">          <property name="cacheSeconds" value="0" />          <property name="messageConverters">              <list>                  <bean class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter"></bean>              </list>          </property>    </bean>              <!-- SpringMVC上传文件时，需要配置MultipartResolver处理器 -->     <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">         <!-- 指定所上传文件的总大小不能超过。注意maxUploadSize属性的限制不是针对单个文件，而是所有文件的容量之和 -->         <property name="maxUploadSize" value="10485760000"/>         <property name="defaultEncoding" value="utf-8"/>         <property name="maxInMemorySize" value="40960"/>     </bean>     </beans>

(3)  applicationContext.xml配置文件，配置bean所用，如下：

<?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"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd"><context:annotation-config /> <!-- 针对使用注解进行配置 --><bean id="springManager" class="com.study.controller.annotation.SpringManaget"></bean></beans>

     3 测试代码：

package com.study.controller.annotation;import javax.annotation.Resource;import javax.servlet.http.HttpServletRequest;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.context.WebApplicationContext;import org.springframework.web.context.support.WebApplicationContextUtils;import org.springframework.web.servlet.support.RequestContextUtils;@RequestMapping("/spring")@Controllerpublic class SpringController {//Ioc@Resource(name = "springManager")//applicationContext.xml中的beanprivate ISpring iSpring;  @RequestMapping("/get")public String get(HttpServletRequest request) {WebApplicationContext webApplicationContext = WebApplicationContextUtils.getWebApplicationContext(request.getSession().getServletContext()); // spring的上下文WebApplicationContext webApplicationContext2 = RequestContextUtils.getWebApplicationContext(request); //springMVC的上下文，集成自spring的上下文//ISpring iSpring = (SpringManaget)webApplicationContext.getBean("springManager");  通过spring的上下文获取bean//ISpring iSpring = (SpringManaget)webApplicationContext2.getBean("springManager");  通过springMVC的上下文获取beanSystem.out.println(iSpring.get());return "/success";}}
