The same ThreadPoolExecutor is used to directly submit work to the pool that can utilize the default J2EE context.

使用同一threadpoolexecut or直接将工作提交到可以利用缺省J2EE上下文的池。

When using a custom thread pool such as a ThreadPoolExecutor, it may not be desirable to run work within a single J2EE context.

在使用自定义线程池（如 ThreadPoolExecutor）时，可能不需要在单个 J2EE 上下文中运行工作。

You don't call the ThreadPoolExecutor constructor directly to create a thread pool but instead use the Executors utility class to create one.

使用Executors工具类来创建线程池，而不是直接调用ThreadPoolExecut or构造器来创建。
