请求调度概念的包含和转发机制之间的区别？ [英] Difference between include and forward mechanism for request dispatching concept?

问题描述

转发（）：这可以通过Request& amp; amp;
ServeletContext。
将来自servlet的请求转发到服务器上的另一个资源
（servlet，JSP
文件或HTML文件）。转发是在
服务器端完成的，没有客户的知识。

Forward() : This can be done in two ways by Request & ServeletContext. Forwarding a request from a servlet to another resource (servlet, JSP file, or HTML file) on the server. Forward is done at server side, without the client's knowledge.

当你调用转发请求时，请求被发送到
另一个$ b服务器上的$ b资源，没有通知客户

不同的资源将处理请求。这个
流程完全在网络容器中发生
。

When you invoke a forward request, the request is sent to another resource on the server, without the client being informed that a different resource is going to process the request. This process occurs completely with in the web container.

简单

包括：将在我们当前文件中包含另一个文件

include: will include another file in our current file

转发：将当前请求转发到转发页面

forward: will forward the current request to the forwarding page

推荐答案

主要区别在于当你使用 forward 时，控件被转移到你正在调用的下一个servlet / jsp，而 include 保留使用当前servlet的控件，它只包括调用servlet / jsp完成的处理（比如执行任何out.println或其他处理）。

The main difference is that when you use forward the control is transferred to the next servlet/jsp you are calling, while include retains the control with the current servlet, it just includes the processing done by the calling servlet/jsp(like doing any out.println or other processing).
