SpringMVC基础

学习MVC的步骤

1.搭建环境

2.如何完成Controller和viewer的映射

3.如何把值传递给Controller

4.Controller如何把值传递给viewer

5.异常处理

6.页面标签

7.文件上传

8.深入源代码

 

1.搭建SpringMVC环境

   创建一个动态的JAVA项目，　导入SpringMVC的jar包和apache的commons-logging 包

2.配置 web.xml文件

创建一个hello servlet,所有请求都通过这个hello servlet来处理

<?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">
    <servlet>
        <servlet-name>hello</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>hello</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
</web-app>

3.创建hello-servlet.xml的配置文件

<?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/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd
        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-3.1.xsd">
    
    <context:component-scan base-package="zttc.itat.controller"/>
    <mvc:annotation-driven/>
    <!-- 将静态文件指定到某个特殊的文件夹中统一处理 -->
    <mvc:resources location="/resources/" mapping="/resources/**"/>
    <bean name="/welcome.html" class="zttc.itat.controller.WelcomeController"></bean>
    
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
        <property name="prefix" value="/WEB-INF/jsp/"/>
        <property name="suffix" value=".jsp"/>
    </bean>
</beans>
