Đây là file HelloController.java thuộc package controller
package controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
@Controller
public class HelloController {
@RequestMapping("/hello")
public ModelAndView SayHello(){
return new ModelAndView("hello", "message", "Hello Spring 3.0");
}
}
Đây là file index.jsp
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>JSP Page</title>
</head>
<body>
<a href ="hello">click this link</a>
</body>
</html>
còn đây là file hello.jsp của e
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>JSP Page</title>
</head>
<body>
<h1>${message}</h1>
</body>
</html>
cấu trúc project của e:
Mới vào e sẽ load file index.jsp, trong trnag đó có 1 link dẫn đến hello.jsp, mà không hiểu sao nó không hiểu (dường như nó không vào file dispatch-servlet.xml
