ruby多线程编程（实例）

3个消费者线程，

2个生产者线程，

同步资源名字叫resources

 

同步采用的MonitorMixin

下面是源码

require 'monitor' class ThreadTest include MonitorMixin # resource,同步资源 attr_accessor :sources,:cond def initialize # 注意,如果自己写initialize方法，super不能省略 super self.cond = new_cond self.sources = [] end # 生产者 # 有2个线程不停的向resource中生产资源 def start_producer_thread ts = [] 2.times do |i| ts << Thread.new do Thread.current[:name] = "producer thread #{i + 1}" loop do synchronize do p = sources.size == 0 ? 1 : sources.last + 1 self.sources << p puts "[#{Thread.current[:name]}] create one product : #{p.to_s.rjust(4)}" cond.signal sleep 0.2 end end end end ts end # 消费者 # 有3个线程不停的从资源（resource）中取得 def start_consumer_thread ts = [] 3.times do |i| ts << Thread.new do Thread.current[:name] = "consumer thread #{i + 1}" loop do synchronize do p = sources.shift puts "[* #{Thread.current[:name]}] consume one product : #{p.to_s.rjust(8)}" cond.signal end end end end ts end def do_it ts = [] # 生产者线程开始 ts << start_producer_thread sleep 1 # 1秒钟后，消费者线程开始 ts << start_consumer_thread # 挂起主线产程，直到生产者与消费者线程结束 ts.flatten.each(&:join) end end ThreadTest.new.do_it 

执行结果：
