错误 404 - Java Servlet Doget 控制器方法

Question

I cant run a simple hello world message on Servlet. Does anyone know what I am doing wrong? Below is my code:

The server is working normally. Tomcat is version 8.

Any help?

Answer 1

Do you also have deployment descriptor file in your project?

Build new Dynamic Web Project in your IDE and Try this code:

@WebServlet(name = "Hello", urlPatterns = { "/hello" })
public class Hello extends HttpServlet {
protected void doGet(HttpServletRequest request,
        HttpServletResponse response) throws ServletException, IOException {
    PrintWriter out = response.getWriter();
    out.print("Hello World");
}}

In this case you don't need to write .xml file for this.
