首先，寫一個Bean
package springmvc.one.web;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.ui.ModelMap;
import org.springframework.validation.BindingResult;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
@Controller
@RequestMapping("/hellOne.act")
public class HelloOneAction {
@RequestMapping
public String handleRequest(String user,Model model) {
System.out.println("用戶名："+user); //GET/POST的入參
model.addAttribute("user", user); //通過Session返回到界面的出參
model.addAttribute("helloWord", "Hello");
return "hellouser";
}
}
再寫一個JSP頁面hellouser.jsp，此頁面放在 WEB-INF/jsp 目錄下，代碼如下：
<html>
<head><title>HelloPage</title></head>
<body>
Test this sample!
<H1> ${helloWord}, ${user}!</H2>
</body>
</html>
接著看看web.xml的配置
<?xml version="1.0" encoding="ISO-8859-1"?>
<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
<description>Spring 2.5 App</description>
<display-name>Spring App Examples</display-name>
<servlet>
<servlet-name>annomvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>2</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>annomvc</servlet-name>
<url-pattern>*.act</url-pattern>
</servlet-mapping>
</web-app>
最后就是，annomvc.xml 文件了。
<?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-2.5.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd">
<context:component-scan base-package="springmvc.one.web"/>
<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"/>
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:prefix="/WEB-INF/jsp/" p:suffix=".jsp"/>
</beans>
好了，見一個Tomcat工程，在 tomcat 中運行，訪問下面連接，就可以運行了。
