问题描述
在我的项目文件夹中,我们在 ContextPath / WEB-INF / Classes / *下有2个java文件.class
名称是 App1.class
和 App2.class
In my project folder,We have 2 java files under ContextPath/WEB-INF/Classes/*.class
names are App1.class
and App2.class
如果我想运行 App1 .class
,我需要在浏览器中触发URL。
If I want to Run App1.class
,Just i need to trigger URL in browser.
http://localhost:8080/Mapping/App1
以同样的方式,如果你想触发 App2 .class
,使用以下链接
in the same way,if you want to trigger App2.class
,use the following link
http://localhost:8080/Mapping/App2
我想从<$ c触发 App2
$ c> App1 ,表示如果在浏览器中触发 App1
并带有相应的URL,则会触发 App2
。
I want to trigger App2
from App1
,means If you trigger App1
with corresponding URL in browser,It will be trigger App2
.
我也不想做任何回复。
我该怎么做。
任何人都可以帮助我。
谢谢。
推荐答案
考虑 App1
和 App2
在 Mapping
web-app中配置为servlet;您可以使用 RequestDispatcher
到 forward()
请求 App2
。这将发生在服务器端,即浏览器将收到响应,好像它来自 App1
。
Considering App1
and App2
are configured as servlets in your Mapping
web-app; you can make use of a RequestDispatcher
to forward()
the request to App2
. This would happen server-side i.e. the browser would receive the response as if its coming from App1
.
if (isForwardReqd()) {
RequestDispatcher rd = request.getRequestDispatcher("App2");
rd.forward(request, response);
}
请注意 App1
在执行 forward()
之前一定不能提交响应,否则你会得到 IllegalStateException
。
Please, note App1
must not have committed a response before doing the forward()
, otherwise you'd get an IllegalStateException
.
