1、获取servlet的别名servlet-name

package com.tangxu.serverlet;
import javax.servlet.*;
import java.io.IOException;
public class servletConfigDemo implements Servlet {
    @Override
    public void init(ServletConfig servletConfig) throws ServletException{
        System.out.println("servletConfigDemo程序的别名是"+servletConfig.getServletName());
     }
    @Override
    public ServletConfig getServletConfig() {
        return null;
    }
    @Override
    public void service(ServletRequest servletRequest, ServletResponse servletResponse) throws ServletException, IOException {
    }
    @Override
    public String getServletInfo() {
        return null;
    }
    @Override
    public void destroy() {
    }
}
