java – 无法从Spring应用程序上下文创建ThreadPoolExecutor

我通过以下方式创建ThreadPoolExecutor时收到IllegalArgumentException.


我究竟做错了什么？
(我在Java 8中使用Spring 3.2)
这是堆栈跟踪.

我试过为corePoolSize和maximumPoolSize传递相同的值,但结果是一样的.


最佳答案
从JavaDoc(1.8)我可以看到以下内容：

@throws IllegalArgumentException if one of the following holds:

我将你的提取添加到我的一个应用程序中,除非我更改参数以违反上述条件之一并因此强制IllegalArgumentException,否则它工作正常.自Java 1.5以来参数的顺序是相同的,因此您的配置应该可以工作.你可以在启动应用程序时提供堆栈跟踪吗？
