Spring MVC 总结一(spring mvc 基本例子)

一、目录结构

二、 具体步骤

　　2.1 applicationContext.xml 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"       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-3.0.xsd">

       <context:annotation-config /></beans>

　　2.2 mvc.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      http://www.springframework.org/schema/beans/spring-beans-3.0.xsd      http://www.springframework.org/schema/context      http://www.springframework.org/schema/context/spring-context-3.0.xsd      http://www.springframework.org/schema/mvc      http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">

       <mvc:annotation-driven/>       <!-- 自动扫描包 -->       <context:component-scan base-package="pr.cgl.controller" />

       <!-- mvc返回页面的配置 -->       <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">              <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>              <!-- 模板路径为WEB-INF/pages/ -->              <property name="prefix" value="/WEB-INF/"/>              <!-- 视图模板后缀为.JSP -->              <property name="suffix" value=".jsp"/>       </bean>

</beans>

　　2.3 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_2_5.xsd" version="2.5">

    <welcome-file-list>        <welcome-file>index.jsp</welcome-file>    </welcome-file-list>    <context-param>        <param-name>webAppRootKey</param-name>        <param-value>SpringWebT1.root</param-value>    </context-param>    <context-param>        <param-name>contextConfigLocation</param-name>        <param-value>            classpath:applicationContext.xml        </param-value>    </context-param>

    <!-- 启动spring 加载 -->    <listener>        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>    </listener>

   <context-param>        <param-name>log4jConfigLocation</param-name>        <param-value>classpath:log4j.properties</param-value>    </context-param>    <listener>        <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>    </listener>

    <!-- 加载springmvc -->    <servlet>        <servlet-name>springmvc</servlet-name>        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>        <init-param>            <param-name>contextConfigLocation</param-name>            <param-value>classpath:mvc.xml</param-value>        </init-param>        <load-on-startup>1</load-on-startup>    </servlet>

    <!-- 以.htm结尾的都被mvc拦截 -->    <servlet-mapping>        <servlet-name>springmvc</servlet-name>        <url-pattern>/SpringWebT1/*</url-pattern>    </servlet-mapping>

</web-app>

　　2.4 添加日志

　　　　2.4.1 配置log4j.properties

### Log4j Properties ###

# Options are <DEBUG, INFO, WARN, ERROR or FATAL>

# Use two appenders, one to log to console, another to log to a filelog4j.rootLogger=ALL,debug,info,error,console#log4j.rootLogger=debug,error,console#log4j.rootLogger=error,consolelog4j.threshold=ALL

    <context-param>        <param-name>log4jConfigLocation</param-name>        <param-value>classpath:log4j.properties</param-value>    </context-param>    <listener>        <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>    </listener>

　　2.5 controller

package pr.cgl.controller;

import org.springframework.stereotype.Controller;import org.springframework.ui.Model;import org.springframework.web.bind.annotation.RequestMapping;

/** * Created by CGL on 2015/9/10. */@Controller@RequestMapping("/main")public class TestController {

    @RequestMapping("/index.html")    public String index(Model m){        m.addAttribute("name", "clg");        return "index";    }}2.6 测试　　地址栏输入http://localhost:8080/SpringWebT1/main/index.html，得到Hello, clg
