I try to learn springmvc.But When I get to start，I encountered a problem.
I think it is a simply problem.And I search for it on internet and find a lot of examples.But i don't find the reason.Here is the code.
HomeControll.java
package cn.qingtianr.controll;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
/**
* Created by jack on 16-5-20.
*/
@Controller
public class HomeControll {
@RequestMapping("/")
public String index(ModelMap model){
String s = "hhh";
model.addAttribute("hello",s);
return "index";
}
}
index.jsp
