1.导入jar包
commons-logging-1.1.1.jar
jackson-annotations-2.5.4.jar
jackson-core-2.5.4.jar
jackson-databind-2.5.4.jar
spring-aop-4.1.6.RELEASE.jar
spring-beans-4.1.6.RELEASE.jar
spring-context-4.1.6.RELEASE.jar
spring-core-4.1.6.RELEASE.jar
spring-expression-4.1.6.RELEASE.jar
spring-tx-4.1.6.RELEASE.jar
spring-web-4.1.6.RELEASE.jar
spring-webmvc-4.1.6.RELEASE.jar
2.配置web.xml-配置分发器,在web.xml文件添加如下代码
<servlet>
<servlet-name>springMVC</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>springMVC</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>
3.添加springMVC配置文件,添加到web-inf目录下,名称规范:[dispatcherServlet]-servlet.xml,本案例为:springMVC-servlet.xml
4.编写控制器类HelloController,实现Controller接口
package com.ahd.controller; import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse; import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.Controller; public class HelloController implements Controller{ public ModelAndView handleRequest(HttpServletRequest req,
HttpServletResponse resp) throws Exception {
// TODO Auto-generated method stub
ModelAndView mv=new ModelAndView(); //设置要显示到视图的信息
mv.addObject("msg", "hello springmvc");
//设置视图名称
mv.setViewName("hello"); return mv;
} }
5.编写springMVC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:p="http://www.springframework.org/schema/p"
xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd"> <!-- 配置handlerMapping -->
<bean class=" org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"></bean>
<!-- 配置handlerAdapter -->
<bean class="org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter"></bean>
<!-- 配置渲染器 -->
<bean id="jspViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
<!-- 将视图名 渲染后视图的前缀 -->
<property name="prefix" value="/WEB-INF/jsp/"/>
<!-- 渲染后视图的后缀 -->
<property name="suffix" value=".jsp"/>
<!-- 例：视图名为:hello 渲染后：/WEB-INF/jsp/hello.jsp 该页面-->
</bean>
<!-- 配置请求和处理器 -->
<bean name="/hello.do" class="com.ahd.controller.HelloController"></bean>
</beans>
