SpringMVC4.2.4 xml配置

　　環境：1、基於spring4.2.4版本，也是spring當前(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與springMVC的配置文件沒有放在默認的WEB-INF下面，而是放在src/main/resources下面

　　spring.xml 主要作用就是掃描非controller的bean,同時也可以承擔引入外部屬性文件，比喻mybatis的屬性文件(連接字符串)

<?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 />

    <!-- 掃描默認包下的所有的@Component注解，並且自動注冊到容器中， 同時也掃描@Controller，@Service，@Respository這三個注解，他們是繼承自@Component。 
        Spring根容器負責所有其他非controller的Bean的注冊 -->
    <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"
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    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">

    <!-- 啟用Spring基於annotation的DI, 使用戶可以在Spring MVC中使用Spring的強大功能。 激活 @Required,@Autowired,JSR 
        250's @PostConstruct, @PreDestroy and @Resource 等標注 -->
    <context:annotation-config />

    <!-- SpringMVC只負責controller相關的Bean的注冊 -->
    <context:component-scan base-package="com.wucj.controller" />

    <!-- 擴充了注解驅動，可以將請求參數綁定到控制器參數 -->
    <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>
