实现Servlet接口
package HelloDemo;
public class Demo1 implements Servlet {
public void service(ServletRequest arg0, ServletResponse arg1) throws ServletException, IOException {
// TODO Auto-generated method stub
System.out.println("这是service方法");
}
@Override
public void destroy() {
// TODO Auto-generated method stub
}
@Override
public ServletConfig getServletConfig() {
// TODO Auto-generated method stub
return null;
}
@Override
public String getServletInfo() {
// TODO Auto-generated method stub
return null;
}
@Override
public void init(ServletConfig arg0) throws ServletException {
// TODO Auto-generated method stub
}
}
方法2：servlet的通用写法
让类去继承servlet的实现类httpservlet,.
package HelloDemo;
public class Demo2 extends HttpServlet {
@Override
protected void service(HttpServletRequest arg0, HttpServletResponse arg1)
throws ServletException, IOException {
// TODO Auto-generated method stub
System.out.println("Demo2! ");
}
@Override
protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
// TODO Auto-generated method stub
super.doGet(req, resp);
System.out.println("this is Get!");
}
@Override
protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
// TODO Auto-generated method stub
super.doPost(req, resp);
System.out.println("this is post!");
}
}
