spring的ParameterMethodNameResolver的使用

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
