SpringMVC实现一个controller写多个方法
SpringMVC实现一个controller写多个方法
MultiActionController与ParameterMethodNameResolver
在一个Controller类中定义多个方法，并根据使用者的请求来执行当中的某个方法，相当于Struts的DispatcherAction。使用MultiActionController需要配个MethodNameResolver实例，默认使用ParameterMethodNameResolver，他会根据所给的网址中，最后请求的文件名称来判断执行Controller中的哪一个方法
1.控制器类继承MultiActionController
复制代码
package com.ljq.web.controller;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.multiaction.MultiActionController;
/**
- 实现一个controller写多个方法
- @author Administrator
*/
public class MultiController extends MultiActionController {
public ModelAndView add(HttpServletRequest request,
HttpServletResponse response) {
System.out.println("----add----");
return new ModelAndView("/multi", "message", "add");
}
public ModelAndView update(HttpServletRequest request,
HttpServletResponse response) {
System.out.println("----update----");
return new ModelAndView("/multi", "message", "update");
}
public ModelAndView query(HttpServletRequest request,
HttpServletResponse response) {
System.out.println("----query----");
return new ModelAndView("/multi", "message", "query");
}
}
复制代码
2.定义控制方法按如下格式
public ModelAndView add(HttpServletRequest request,
HttpServletResponse response) {
System.out.println("----add----");
return new ModelAndView("/multi", "message", "add");
}
3.在dispatcher-servlet.xml文件中引入多视图控制
<bean id="paramMethodResolver" class="org.springframework.web.servlet.mvc.multiaction.ParameterMethodNameResolver">
<property name="paramName" value="action"></property>
</bean>
然后注入自己的控制器类
<bean name="/multi" class="com.ljq.web.controller.MultiController">
<property name="methodNameResolver">
<ref bean="paramMethodResolver"/>
</property>
</bean>
4.完善或者添加一个视图(multi.jsp)，对应控制器类的跳转
复制代码
<%@ page language=“java” contentType=“text/html; charset=UTF-8”
pageEncoding=“UTF-8”%>
<%@taglib prefix=“c” uri=“http://java.sun.com/jsp/jstl/core”%>
访问路径：
http://localhost:8083/springmvc/multi?action=add
http://localhost:8083/springmvc/multi?action=update
http://localhost:8083/springmvc/multi?action=querySpringMVC实现一个controller写多个方法
