案例：使用springMVC编写用户注册页面 在注册成功页面显示注册的信息
1、先导入springmvc相关jar包(-----------建议在WEB-INF下的lib里添加，然后引用)
2、配置web.xml(-----------springmvc 以.do结尾)
<?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>springmvc2</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> <!-- 在spring-webmvc-3.2.9.RELEASE.jar里面--> <servlet> <servlet-name>springmvc</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> </servlet> <servlet-mapping> <servlet-name>springmvc</servlet-name> <url-pattern>*.do</url-pattern> </servlet-mapping> </web-app>
3、在WEB-INF文件下建文件springmvc-servlet.xml文件(-----------bean的name名字下要有/斜杠，视图解析器的前后缀要注意)
<?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"
xmlns:aop="http://www.springframework.org/schema/aop"
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/aop
http://www.springframework.org/schema/aop/spring-aop-3.0.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx-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"
>
<!-- 视图解析器 配置前缀和后缀 要据modelAndView中封装视图名找到目标页面-->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/view/"></property>
<property name="suffix" value=".jsp"></property>
</bean>
<bean name="/hello.do" class="com.wh.controller.HelloController"/>
</beans>
4、配置Controller(-----------注意是转到helloTo页面)
package com.wh.controller;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.AbstractController;
public class HelloController extends AbstractController {
@Override
protected ModelAndView handleRequestInternal(HttpServletRequest request,
HttpServletResponse response) throws Exception {
String name = request.getParameter("name");
System.out.println(name);
ModelAndView mav = new ModelAndView("helloTo");// 转到helloTo.jsp页面
mav.addObject("rel", name);
return mav;
}
}
5、编写hello.jsp(-----------要注意，action后的地址，不用加斜杠/,这点很容易犯错，会导致跳转不到正确的页面)
<form action="hello.do" method="post"> <input name="name" type="text"/> <input type="submit" value="提交"/> </form>
6、在WebRoot下新建view文件夹，在该文件夹下新建helloTo.jsp文件
<body>
rel:${rel}
</body>
效果图如下：
