Tomcat的背景线程 [英] tomcat background threads

问题描述

我正在运行一个tomcat 6.20实例，并且想通过后台线程发送电子邮件，以防止电子邮件发送功能阻止请求.

I have a tomcat 6.20 instance running, and would like to send an email via a background thread to prevent the email sending function from blocking the request.

有什么方法可以在后台执行线程，同时仍然允许正常的页面流发生.

Is there any way I can execute the thread in the background, while still allowing normal page flow to occur.

该应用程序是用ICEfaces编写的.

The application is written in ICEfaces.

谢谢.

推荐答案

1. 在控制器/servlet的初始化方法中使用java.util.concurrent.Executors.newCachedThreadPool(或其他工厂方法之一)创建一个Executor.
2. 收到请求后，将邮件发送逻辑包装在java.lang.Runnable
中
3. 将Runnable提交给Executor

1. Create an Executor using java.util.concurrent.Executors.newCachedThreadPool (or one of the other factory methods) in your controller/servlet's initialization method.
2. When a request comes in, wrap the mail-sending logic in a java.lang.Runnable
3. Submit the Runnable to the Executor

这将在后台执行发送.记住在启动时创建一个执行器，并在所有请求中共享；不要每次都创建一个新的Executor(您可以，但这会有点慢且浪费).

This will perform the sending in the background. Remember to create a single Executor at startup, and share across all the requests; don't create a new Executor every time (you could, but it would be a bit slow and wasteful).
