Spring MVC Controller配置方式

<!-- 表示将请求的URL和Bean名字映射-->  
<bean class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"/>
<bean name="/hello.do" class="test.HelloController"></bean> 

<!-- 最常用的映射配置方式 -->  
<!-- <prop key="/hello*.do">helloController</prop>-->  
<bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">  
 <property name="mappings">  
  <props>  
   <prop key="/hello.do">helloController</prop>  
  </props>  
 </property>  
</bean>  
<bean name="helloController" class="test.HelloController"></bean>

<!-- 将hello*.do交给helloController处理-->  
<bean class="org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping"></bean>  
<bean name="helloController" class="test.HelloController"></bean> 

<!-- 启用 spring 注解 -->  
<context:component-scan base-package="test" />  
<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"/>

package test;  
import java.util.Date;  
import javax.servlet.http.HttpServletRequest;  
import javax.servlet.http.HttpServletResponse;  
import org.springframework.web.bind.annotation.RequestMapping;  
// http://localhost:8080/spring/hello.do?user=java  
@org.springframework.stereotype.Controller  
public class HelloController{  
    @SuppressWarnings("deprecation")  
    @RequestMapping("/hello.do")  
    public String hello(HttpServletRequest request,HttpServletResponse response){  
        request.setAttribute("user", request.getParameter("user") + "-->" + new Date().toLocaleString());  
        return "hello";  
    }  
}
