Issue
I am new to Spring MVC and Servlets. I am trying to run home() method in controller class SearchController but the output is only from home.jsp file. Statement:
out.println("<h1> this is my response block</h1>");
in not included in the result on browser.
Is there anything that can be done to print the out object statement in the browser with home.jsp file?
package springmvcsearch;
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.http.HttpServletResponse;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class SearchController {
@RequestMapping("/home")
public String home(HttpServletResponse res) throws IOException {
res.setContentType("text/html");
PrintWriter out = res.getWriter();
out.println("<h1> this is my response block</h1>");
return "home";
}
}
This is home.jsp
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="ISO-8859-1">
<title>Insert title here</title>
<link href="<c:url value='/resources/css/style.css' />"
rel="stylesheet">
<script src="<c:url value='/resources/js/sample.css' /> "></script>
</head>
<body>
This is home view
</body>
</html>
This is the output on the browser:
Solution
out.println() is used in jsp file. So you can edit your home.jsp as follows
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="ISO-8859-1">
<title>Insert title here</title>
<link href="<c:url value='/resources/css/style.css' />"
rel="stylesheet">
<script src="<c:url value='/resources/js/sample.css' /> "></script>
</head>
<body>
This is home view
<%
out.println("<h1> this is my response block</h1>");
%>
</body>
</html>
If you want to add something for home.jsp via the controller class, you can change your controller class as follows.
package springmvcsearch;
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.http.HttpServletResponse;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class SearchController {
@RequestMapping("/home")
public String home(HttpServletRequest req,HttpServletResponse res) throws IOException {
res.setContentType("text/html");
PrintWriter out = res.getWriter();
String message = "this is my response block";
req.setAttribute("message", message);
return "home";
}
}
Then change your jsp file as follows.
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="ISO-8859-1">
<title>Insert title here</title>
<link href="<c:url value='/resources/css/style.css' />"
rel="stylesheet">
<script src="<c:url value='/resources/js/sample.css' /> "></script>
</head>
<body>
This is home view
<h1>${message}</h1>
</body>
</html>
