eclipse ee servlet tomcat doPost http405
I'm trying to go a post from HTML to Java Servlet using eclipse ee and tomcat starting the server through eclipse. But I am getting: HTTP Status 405 - HTTP method POST is not supported by this URL
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript">
</script>
</head>
<body>
<fo开发者_运维知识库rm method="POST" action="AddHost">
Host name : <input name="hostname" type="text"><br>
Genre : <input name="genre" type="text" ><br>
<input type="submit" value="add host">
</form>
</body>
</html>
This is the servlet:
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.io.PrintWriter;
import java.sql.*;
@WebServlet("/AddHost")
public class Addhost extends HttpServlet {
public void doPost(HttpServletResponse res,HttpServletRequest req) throws IOException{
String hostname = req.getParameter("hostname");
String genre = req.getParameter("genre");
}
public void doGet(HttpServletResponse res,HttpServletRequest req) throws IOException{
doPost(res,req);
}
You have used bad signature of method doPost and instead of overriding, you are overloading
From javadoc HttpServlet contains:
protected void doPost(HttpServletRequest req, HttpServletResponse resp)
So you should change this:
public void doPost(HttpServletResponse res,HttpServletRequest req)
to this:
@Override
public void doPost(HttpServletRequest req, HttpServletResponse res)
@Override annotation is not necessary but strongly recommended to avoid such mistakes.
edited: I added override annotation like mth suggested
加载中,请稍侯......
