基于MAVEN构建Spring MVC初始化配置

初始化一个Spring MVC配置的例子，会逐步完善。

1.pom.xml配置

<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">

        <spring.version>3.1.2.RELEASE</spring.version>
        <!-- maven默认使用jdk1.5编译，此配置设置使用1.8 -->
        <maven.compiler.source>1.8</maven.compiler.source>
        <maven.compiler.target>1.8</maven.compiler.target>
    </properties>

2.web.xml配置

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee 
    http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
    <display-name>Archetype Created Web Application</display-name>

    <servlet>
        <!-- servlet名称 -->
        <servlet-name>springcloud</servlet-name>
        <!-- servlet对应的java类  -->
        <servlet-class>
        org.springframework.web.servlet.DispatcherServlet
        </servlet-class>
        <!-- servlet参数信息 -->
        <init-param>
        <!-- servlet配置文件路径 -->
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/springcloud-config.xml</param-value>
        </init-param>
        <!-- 在web应用启动时立即加载servlet  -->
        <load-on-startup>1</load-on-startup>    
    </servlet>
    
    <!-- servlet映射声明 -->
    <servlet-mapping>
    <!-- 请求对应的servlet名称 -->
    <servlet-name>springcloud</servlet-name>
    <!-- 监听当前域的所有请求 -->
    <url-pattern>/</url-pattern>
    </servlet-mapping>
    
</web-app>

3.controller-config配置

<?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:context="http://www.springframework.org/schema/context"

    <context:annotation-config />

    <context:component-scan base-package="springcloud.controller">
        <context:include-filter type="annotation"
            expression="org.springframework.stereotype.Controller" />
    </context:component-scan>

    <bean
        class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/jsp/" />
        <property name="suffix" value=".jsp" />
    </bean>

    <!--200*1024*1024即200M resolveLazily属性启用是为了推迟文件解析，以便捕获文件大小异常 -->
    <bean id="multipartResolver"
        class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
        <property name="maxUploadSize" value="209715200" />
