[置顶] java web 动态服务器

 

 

 

 

 

 

写了一个java web 动态服务器,主要通过内部类来实现,动态类使用了外部类,采用了

 

classforname 实例化,动态类的构造方法不能带参数, 效果都出来了,分享给有需要的

 

朋友。判断做的不够多,

 

写得不够好,感谢指出缺点。以下是代码:

独立动态类的代码:

import java.util.Date;


public class Visit {
 public Visit(/*Response response, Request request*/) {
  // TODO Auto-generated constructor stub
  /*this.request=request;
  this.response=response;*/
  //this.process();
 }
 
 public void process(Response response, Request request){
  response.out("动态网页"+new Date().toString());
  System.out.println("process------------start");
 }
}
