spring的ParameterMethodNameResolver

spring的ParameterMethodNameResolver的可以根据不同的参数执行不同方法,类似Struts的dyncaction
下面有一个例子
package ee.bug;

import java.util.ArrayList;
import java.util.Date;
import java.util.List;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.multiaction.MultiActionController;
public class ProductController extends MultiActionController {

/**
  * Handles view
  */
public ModelAndView view(HttpServletRequest request, HttpServletResponse response) throws Exception {

  response.getOutputStream().print("Viewing");

  return null;
}

/**
  * Handles index
  */
public ModelAndView index(HttpServletRequest request, HttpServletResponse response) throws Exception {
  response.getOutputStream().print("index");
  return null;
}

}
配置文件
<bean id="productMethodNameResolver" class="org.springframework.web.servlet.mvc.multiaction.ParameterMethodNameResolver">
        <property name="paramName"><value>method</value></property>
        <property name="defaultMethodName"><value>view</value></property>
    </bean>
    <bean id="productController" class="ee.bug.ProductController">
        <property name="methodNameResolver"><ref local="productMethodNameResolver"/></property>
    </bean>
     <property name="paramName"><value>method</value></property>参数名为method 默认为action
    
输入view.do?method=view 显示Viewing
输入view.do?method=indedx 显示index
输入/view.do?method=fdsf  显示404错误
