springMVC(5) springMVC一個controller寫多個方法
阿新 • • 發佈：2019-01-10
上面的例子都是實現Controller,實現handleRequest方法，我們想像struts2那樣一個action裡有多個方法怎麼辦？
可以繼承MultiActionController類，在類裡寫多個方法。spring-servlet.xml裡需要配置ParameterMethodNameResolver。
MultiController：
package com.xdy.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; public class MultiController extends MultiActionController{ public ModelAndView add(HttpServletRequest request, HttpServletResponse response) throws Exception { System.out.println("---add---"); return new ModelAndView("/welcome","method","add"); } public ModelAndView update(HttpServletRequest request, HttpServletResponse response) throws Exception { System.out.println("---update---"); return new ModelAndView("/welcome","method","update"); } }
spring-servlet.xml：
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd"> <beans> <bean name="/multi" class="com.xdy.controller.MultiController"> <property name="methodNameResolver" ref="parameterMethodNameResolver"></property> </bean> <bean id="parameterMethodNameResolver" class="org.springframework.web.servlet.mvc.multiaction.ParameterMethodNameResolver"> <property name="paramName" value="action"></property> </bean> <!-- 配置解析器 --> <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/"/> <property name="suffix" value=".jsp"/> </bean> </beans>
