1、新建一个MAVEN项目，以下图html

2、在filter中输入webapp筛选出maven-archetype-webapp （标准的web项目结构）java

3、填写项目信息web

4、点击FINISH 后可见到如下的目录结构redis

5、添加MAVEN目录文件夹spring

6、修改编译路径apache

src/main/resources　　对应　　target/classesjson

src/main/java　　对应　　target/classesapi

src/test/resources　　对应　　target/test-classesspring-mvc

src/test/java　　对应　　target/test-classessession

七：设定JRE （maven构建出来的JRE 未必符合你的需求，看状况修改）

 

8、转换项目类型（转换为标准的WEB项目并设定WEB的文件路径）

至此项目的环境已经搭建完毕！！！！

下面开始用SPRING MVC框架来搭建应用

一、添加必要的依赖包

<project xmlns="http://maven.apache.org/POM/4.0.0" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

</project>

而后就慢慢等待依赖包下载完！

2、组织项目结构（说白了就是建文件夹来管理相应的资源文件，这个不说了，直接上图）

三、编写配置文件（applicationContext.xml 、springmvc-servtle.xml、web.xml）

applicationContext.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:aop="http://www.springframework.org/schema/aop"
    xmlns:tx="http://www.springframework.org/schema/tx"
	xmlns:context="http://www.springframework.org/schema/context"    
    xsi:schemaLocation="http://www.springframework.org/schema/beans 
    	http://www.springframework.org/schema/beans/spring-beans-4.2.xsd
    	http://www.springframework.org/schema/aop

		http://www.springframework.org/schema/tx 
		http://www.springframework.org/schema/tx/spring-tx-4.2.xsd
		http://www.springframework.org/schema/context 
		http://www.springframework.org/schema/context/spring-context-4.2.xsd"
    default-autowire="no"> 
    <!-- 自动装配-->
    <context:annotation-config />
    <!-- 自动装配的包路径-->
    <context:component-scan base-package="com.niver" />
	
	<!-- 事务（注解 ）-->
	<tx:annotation-driven transaction-manager="transactionManager" proxy-target-class="true"/> 
	
</beans>

springmvc-servtle.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:mvc="http://www.springframework.org/schema/mvc"

   	 	http://www.springframework.org/schema/context/spring-context-4.2.xsd
   	 	http://www.springframework.org/schema/mvc 
   	 	http://www.springframework.org/schema/mvc/spring-mvc-4.2.xsd">

	<!-- 设置使用注解的类所在的jar包 -->
	<context:component-scan base-package="com.niver.web" />
	<!-- Enables the Spring MVC @Controller programming model -->
	<mvc:annotation-driven />
	
    <!-- 拦截器配置，没有的能够不要这一段 -->
	<mvc:interceptors>
	    <!-- 使用bean定义一个Interceptor，直接定义在mvc:interceptors根下面的Interceptor将拦截全部的请求 -->  
	    <bean class="com.niver.core.interceptor.CommonInterceptor"/>  
		<mvc:interceptor> 
	        <mvc:mapping path="/login/*"/> 
	        <!-- 定义在mvc:interceptor下面的表示是对特定的请求才进行拦截的 -->  
	        <bean class="com.niver.core.interceptor.LoginInterceptor"/>  
	    </mvc:interceptor>  
	</mvc:interceptors>
	
	<!-- 对转向页面的路径解析。prefix：前缀， suffix：后缀 -->
	<mvc:view-resolvers>
	    <mvc:jsp cache-views="false" prefix="/WEB-INF/jsp/" suffix=".jsp" />  
	</mvc:view-resolvers>
	
	<bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter">
		<description>注解controller方法适配器</description>
		<property name="messageConverters">
			<list><!--JSON转换器 -->
				<bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
					<property name="supportedMediaTypes" value="application/json;charset=UTF-8" />
				</bean>
			</list>
		</property>
	</bean>
	    
	<bean class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
		<description>配置文件上传</description>
		<property name="defaultEncoding" value="utf-8" />
		<!-- 文件大小最大值 -->
		<property name="maxUploadSize" value="10485760000" />
		<!-- 内存中的最大值 -->
		<property name="maxInMemorySize" value="40960" />
	</bean>
</beans>

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"

	version="3.0">

	<display-name></display-name>
			
	<!-- Spring配置 -->
	<listener> 
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> 
	</listener> 

	<!-- 指定Spring Bean的配置文件所在目录。默认配置在WEB-INF目录下 -->
	<context-param> 
		<param-name>contextConfigLocation</param-name>

	</context-param>
	
	<filter>

		<async-supported>true</async-supported>

	</filter>
	<filter-mapping>
		<filter-name>encodingFilter</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>
	
	<!-- springMVC 配置 -->
	<servlet>
        <servlet-name>SpringMVC</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>

			<param-value>classpath:config/SpringMVC-servlet.xml</param-value>
		</init-param>
		<load-on-startup>1</load-on-startup>
		<async-supported>true</async-supported>
    </servlet>
    <servlet-mapping>
        <servlet-name>SpringMVC</servlet-name>
        <url-pattern>*.xhtml</url-pattern><!--这个后缀本身喜欢，哈哈哈 -->
    </servlet-mapping>
	
	<welcome-file-list>
		<welcome-file>index.xhtml</welcome-file>
	</welcome-file-list>
</web-app>

而后就差很少了。

额。。。若是想在eclipse 直接运行的话，记得把编译用到的JAR加载进去，毕竟MAVEN的包不在WEB-INF的lib下！

具体按照下图去弄就行了！
