spring和spring MVC整合

spring和springMVC之间的整合，springMVC中的jar包包含spring中的jar包，所以无需再另外导入jar包，只需导入springMVC的jar包即可。

如图一所示:

这个时候，再新建两个源文件夹，一个为config专门放配置文件，另外一个为test，专门用来放进行测试的程序，在这个整合的小项目中，本身

并没有用上test源文件夹，但是加上倒也不错。

现在，在config文件夹中新建两个xml文件，一个为spring的配置文件，为applicationContext.xml,另一个为springmvc 的配置文件为springmvc.xml,两个xml

文件的配置如下：

applicationContext.xml:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN 2.0//EN" "http://www.springframework.org/dtd/spring-beans-2.0.dtd" [
<!ENTITY contextInclude SYSTEM "org/springframework/web/context/WEB-INF/contextInclude.xml">
]>
<beans>
	<bean id="springManager" class="cn.com.controller.SpringManager"></bean>
</beans>

springmvc.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:mvc="http://www.springframework.org/schema/mvc"
	xmlns:context="http://www.springframework.org/schema/context"
	xmlns:aop="http://www.springframework.org/schema/aop"
	xmlns:tx="http://www.springframework.org/schema/tx"
	xsi:schemaLocation="http://www.springframework.org/schema/beans
		http://www.springframework.org/schema/beans/spring-beans-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/context
		http://www.springframework.org/schema/context/spring-context-3.0.xsd
		http://www.springframework.org/schema/aop
		http://www.springframework.org/schema/aop/spring-aop-3.0.xsd
		http://www.springframework.org/schema/tx
		http://www.springframework.org/schema/tx/spring-tx-3.0.xsd ">							

		<!-- mvc的注解驱动 -->
		<mvc:annotation-driven/>
		<!-- 一旦有扫描器的定义mvc:annotation-driven不需要，扫描器已经有了注解驱动的功能 -->
		<context:component-scan base-package="cn.com.controller"/>

		<!-- 前缀+ viewName +后缀 -->
		<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
			<!-- webroot到某一指定的文件夹的路径 -->
			<property name="prefix" value="/WEB-INF/jsps/"></property>
			<!-- 视图名称的后缀 -->
			<property name="suffix" value=".jsp"></property>
		</bean>

		<!-- id="multipartResolver"必须是multipartResolver -->
		<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
			<!-- maxUploadSize:文件上传的最大值以byte为单位 -->
			<property name="maxUploadSize" value="1024000"></property>
		</bean>

		<!-- <mvc:interceptors>
			<mvc:interceptor>
				某一模块的拦截：/myPath/**, 拦截所有的请求/**
				<mvc:mapping path="/**"/>
				<bean class="cn.itcast.springmvc.interceptor.MyIntercepor"></bean>
			</mvc:interceptor>
		</mvc:interceptors> -->
</beans>

现在，在web.xml中去进行相应的配置，web.xml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" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
	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">
  	<context-param>
  		<param-name>contextConfigLocation</param-name>
  		<param-value>classpath:applicationContext.xml</param-value>
  	</context-param>
  	<!-- 配置spring启动listener入口 -->
  	<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>

	<!-- 配置springmvc启动dispatcherServlet入口 -->
	<!-- 中央控制器 -->
	<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:springmvc.xml</param-value>
		</init-param>
		<load-on-startup>1</load-on-startup>
	</servlet>

	<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>
	<!-- encoding filter for jsp page -->
	<filter-mapping>
		<filter-name>encodingFilter</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>

	<servlet-mapping>
		<servlet-name>springMVC</servlet-name>
		<!-- struts习惯使用/*，在springmvc不管用 -->
		<url-pattern>/</url-pattern>
	</servlet-mapping>

</web-app>

现在建立springmvc.xml中扫描的包,具体包名与类名如下：

下面依次为各个程序的代码：

ISpring:

package cn.com.controller;

public interface ISpring {
	void get();
}

SpringManager:

package cn.com.controller;

public class SpringManager implements ISpring {

	public void get() {
		System.out.println("spring和spring mvc整合成功！");
	}

}

UserController:

package cn.com.controller;

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;

@Controller
@RequestMapping("/user")
public class UserController {

	@Resource(name="springManager")

	private ISpring springManager;
	@RequestMapping("/toSuccess.do")
	public String ToSuccess(HttpServletRequest request){
		//spring上下文
		WebApplicationContext ac1 = WebApplicationContextUtils.getWebApplicationContext(request.getSession().getServletContext());
		//springmvc的上下文
		WebApplicationContext ac2=RequestContextUtils.getWebApplicationContext(request);
		springManager.get();
		return "success";
	}
}

如此，spring和springmvc的整合完成了，现在让我们将这个项目跑起来看一下到底成功了没有。

debug调试观察ac1与ac2：

如下图所示：

spring上下文：

springmvc上下文：

jsp页面为：

如此，spring和springmvc的整合就成功了。
