Java NIO、BIO、 AIO 与同步、阻塞、非阻塞、异步IO 简析

我相信大部分人看到这些名词，都是一头雾水的，如果你去搜索引擎搜索，那么恭喜你，你又会被各种文章中的高大上的名词搞得云里雾里。那么，我们应该怎么理清这么名词之间的关系呢？所谓同步/异步/阻塞/非阻塞 IO ，是指操作系统中的对 IO 处理的不同方法，而 Java 对这些不同操作方法做了...

Java NIO -- 阻塞和非阻塞

传统的 IO 流都是阻塞式的。也就是说，当一个线程调用 read() 或 write()时，该线程被阻塞，直到有一些数据被读取或写入，该线程在此期间不能执行其他任务。因此，在完成网络通信进行 IO操作时，由于线程会阻塞，所以服务器端必须为每个客户端都提供一个独立的线程进行处理，当服务器端需要处理大量...

java nio 操作（2）异步阻塞 socket实现

一.同步阻塞IO BIO就是阻塞式的IO，网络通信中对于多客户端的连入，服务器端总是与客户端数量一致的线程去处理每个客户端任务，即，客户端与线程数1:1，并且进行读写操作室阻塞的，当有你成千上完的客户端进行连接，就导致服务器...

java的nio之：java的bio流下实现的socket服务器同步阻塞模型和socket的伪异步的socket服务器的通信模型

同步I/O模型的弊端===>每一个线程的创建都会消耗服务端内存，当大量请求进来，会耗尽内存，导致服务宕机伪异步I/O的弊端分析===>当对Socket的输入流进行读取操作的时候，它会一直阻塞下去，知道发生如下三件事情（1）有数据可读（2）可用数据已经读取完毕（3）发生空指针或者I/O异常...

java nio 关闭客户端服务器端的selector.select(TimeOut)方法为什么不阻塞

代码如下： // 反复循环,等待IO while (true) { // 等待某信道就绪(或超时) if (selector.select(TimeOut) == 0) {// 监听注册通道，当其中有注册的 IO // 操作可以进行时，该函数返回，并将对应的...
