SpringMVC4.2.4 xml配置

　　环境：1、基于spring4.2.4版本，也是spring当前(2016.2)最新的GA版本　

　　　　　2、maven 3.2.1

　　　　　3、jdk1.7

　　xml配置1：

　　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_3_0.xsd"
    id="WebApp_ID" version="3.0">

    <display-name>SpringMVC</display-name>

    <!-- Spring配置；MyBatis配置 -->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:spring.xml</param-value>        <!-- classpath:spring.xml,classpath:spring-mybatis.xml -->
    </context-param>

    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    <!-- Spring MVC配置 -->
    <servlet>
        <servlet-name>dispatcherServlet</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>dispatcherServlet</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

</web-app>

　　xml配置2：spring与springMVC的配置文件没有放在默认的WEB-INF下面，而是放在src/main/resources下面

　　spring.xml 主要作用就是扫描非controller的bean,同时也可以承担引入外部属性文件，比喻mybatis的属性文件(连接字符串)

<?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"
    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.xsd
        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc.xsd">

    <context:annotation-config />

    <!-- 扫描默认包下的所有的@Component注解，并且自动注册到容器中， 同时也扫描@Controller，@Service，@Respository这三个注解，他们是继承自@Component。
        Spring根容器负责所有其他非controller的Bean的注册 -->
    <context:component-scan base-package="com.wucj">
        <context:exclude-filter type="annotation"
            expression="org.springframework.stereotype.Controller" />
    </context:component-scan>

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

    xsi:schemaLocation="

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

    <!-- 启用Spring基于annotation的DI, 使用户可以在Spring MVC中使用Spring的强大功能。 激活 @Required,@Autowired,JSR
        250‘s @PostConstruct, @PreDestroy and @Resource 等标注 -->
    <context:annotation-config />

    <!-- SpringMVC只负责controller相关的Bean的注册 -->
    <context:component-scan base-package="com.wucj.controller" />

    <!-- 扩充了注解驱动，可以将请求参数绑定到控制器参数 -->
    <mvc:annotation-driven />

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

</beans>
