SpringMVC学习笔记(一)

// 搭建最基本的Spring MVC框架

// 1.导入相应的包，附件案例中有相应的包

// 2.编写spring-servlet.xml配置文件，这个文件放在同web.xml同一目录下即可

<?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"
	xmlns:context="http://www.springframework.org/schema/context"
	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">
    <!-- 指定扫描的包 -->
	<context:component-scan base-package="com.cc.testSpringMVC.web" />
	<bean id="viewResolver"
		class="org.springframework.web.servlet.view.UrlBasedViewResolver">
		<property name="viewClass"
			value="org.springframework.web.servlet.view.JstlView" />
		<property name="prefix" value="/" />
		<property name="suffix" value=".jsp" />
	</bean>
</beans>

 // 3.配置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" id="WebApp_ID" version="2.5">
  <display-name>TestSpringMVC</display-name>
  <welcome-file-list>
    <welcome-file>index.html</welcome-file>
    <welcome-file>index.htm</welcome-file>
    <welcome-file>index.jsp</welcome-file>
    <welcome-file>default.html</welcome-file>
    <welcome-file>default.htm</welcome-file>
    <welcome-file>default.jsp</welcome-file>
  </welcome-file-list>
  
  
    <servlet>
        <servlet-name>spring</servlet-name>
        <servlet-class>
            org.springframework.web.servlet.DispatcherServlet
        </servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>spring</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
</web-app>

 

 

// 4.编写相应的控制器，目录就是spring-servlet.xml配置中，扫描的包

@Controller
public class TController {

	// 只接收post请求，如果不写，则都可以
	@RequestMapping(value="index",method=RequestMethod.POST)
	public ModelAndView index(HttpServletRequest request) {
		String str = "Spring MVC";
		
		// 返回指定的jsp页面
		ModelAndView mav = new ModelAndView("message");
		// 添加参数
		mav.addObject("str",str);
		
		return mav;
	}

}

 // 5.最后编写相应的jsp文件index.jsp与success.jsp
