Following previous article, "Spring MVC HelloWorld example Part 1
In this part, I am going to show example on how to define Handler Mapping in our xml setting file.
By Default, SpringMVC is using "BeanNameUrlHandlerMapping" as HandlerMapping,
there are two other HandlerMapping for our choices.
2. ControllerClassNameHandlerMapping
3. SimpleUrlHandlerMapping.
The only two differences would be in "HelloWeb-servlet.xml" and our Controller class
I have marked the line of codes that is different from previous example.
1. HelloWeb-servlet.xml
<beans xmlns = "http://www.springframework.org/schema/beans" xmlns:context = "http://www.springframework.org/schema/context" xmlns:xsi = "http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation = " http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd"> <bean name ="ControllerClassNameHandler" class="org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping"></bean> <bean name="/helloworld" class = "com.yang.HelloController"></bean> <bean id ="viewresolver" class = "org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name = "prefix" value = "/WEB-INF/jsp/" /> <property name = "suffix" value = ".jsp" /> </bean> </beans>
2. Controller Class
package com.yang; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import org.springframework.web.servlet.ModelAndView; import org.springframework.web.servlet.mvc.AbstractController; public class HelloController extends AbstractController{ @Override protected ModelAndView handleRequestInternal(HttpServletRequest arg0, HttpServletResponse arg1) throws Exception { // TODO Auto-generated method stub ModelAndView mv = new ModelAndView(); mv.addObject("message", "Hello Spring MVC Framework!"); mv.setViewName("success"); return mv; } }
