Intellij JSP - Servlet 생성 및 매핑

Servlet 생성 및 매핑

1. Intellij Servlet 생성

• 마우스 우클릭 -> New -> Create New Servlet

• Create Java EE 6 annotated class 체크

2. Servlet 매핑

• Annotation을 이용한 매핑

    @WebServlet("/Serv") // Annotation을 이용한 매핑 (= @WebServlet(urlPatterns = "/Serv") = @WebServlet(value = "/Serv"))
    public class Servlet extends HttpServlet {
            protected void doPost(HttpServletRequest request, HttpServletResponse response) throws javax.servlet.ServletException, IOException {
  
            }
  
            protected void doGet(HttpServletRequest request, HttpServletResponse response) throws javax.servlet.ServletException, IOException {
                    PrintWriter out = response.getWriter();
                    out.println("Hello World");
            }
    }
  

• web.xml을 이용한 매핑

    <servlet>
            <servlet-name>ServletTest</servlet-name>
            <servlet-class>example.Servlet</servlet-class>
    </servlet>
    <servlet-mapping>
            <servlet-name>ServletTest</servlet-name>
            <url-pattern>/Serv</url-pattern>
    </servlet-mapping>
