我可以从Servlet产生线程吗? [英] Can i spawn a thread from a servlet?

问题描述

在开始我的主要问题之前，我想问一个基本问题.

I would like to ask a basic question before i get on to my main question .

可以说我正在运行一个简单的Java程序，该程序在main函数中产生一个线程.当主要功能完成时，线程会继续运行吗? 线程之间是否有父/子关系的概念.

Lets say i am running a simple Java program, which spawns a thread in the main function. Will the thread continue to run when the main function completes? Is there a concept of parent/child relationships between threads.

我有一个Servlet，需要很长时间才能处理请求(5分钟).我可以从主servlet中产生一个后台线程来处理工作吗?很快回来.即使主servlet完成处理后，后台线程也会继续运行吗?

I have a servlet which takes a long while to process a request (5 mins). Can i spawn a background thread from the main servlet to handle the work & return soon. Would the background thread keep running even when the main servlet has finished processing?

推荐答案

• 有诸如父线程和子线程之类的东西，但是您对此没有太多的控制权.例如，存在InheritableThreadLocal，您可以在其中存储线程层次结构的变量.

  • There is such thing as parent and child threads, but you don't have a lot of control on that. For example there's InheritableThreadLocal, where you can store variables for a thread hierarchy.

    您可以从servlet产生一个新线程.首选Java 5执行程序框架

    you can spawn a new thread from a servlet. Prefer Java 5 executors framework

    如果使用Servlet 3.0，请查看其

    if using servlet 3.0, take a look at its asynchronous processing capabilities.
