4. FileUploadController.java

package edu.xmu.mavenspring.controls;

import javax.servlet.http.HttpServletResponse;

import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.Controller;

Comments;
1. This is just a simple demo for showing how to build dependencies for springMVC in Maven.

2. And only use a simple fraction of springMVC capablities.

3. Remember to include jstl dependencies in pom.xml for ${message} to be shown correctly.

4. Useful links:

1) http://jinnianshilongnian.iteye.com/category/231099?page=2 ---> Show SpringMVC in details

2) http://mvnrepository.com/ ---> Where we can find dependencies <groupId & artifactId & version>
