Java中的连接池和线程池设置 使用Hikari连接池的Spring应用。 现在,为了满足业务需求,我必须查询10个表以生成一个响应。对于每一个表的查询,可能需要50毫秒到200毫秒不等的时间。为了加快响应时间,我在我的服务中创建了一个FixedThreadPool来在不同线程中查询每个表(伪代码): class MyService{ final int THREAD_PO...

javamultithreading 35 我发现有两种方法(submit和execute)可以将一个Runnable添加到线程池中,它们之间的区别是什么? -virsir 3个回答 39 区别在于execute不返回Future,因此您无法使用它等待Runnable的完成并获取任何它抛出的异常。 -ColinD 4Future还允许您获取由Runnable抛出的异常。- axtavt ...

在前面的一篇文章里我对java threadpool的几种基本应用方法做了个总结。Java的线程池针对不同应用的场景,主要有固定长度类型、可变长度类型以及定时执行等几种。针对这几种类型的创建,java中有一个专门的Executors类提供了一系列的方法封装了具体的实现。这些功能和用途不一样的线程池主要依赖于ThreadPoolExecutor,Schedu...
