Java协程框架Quasar Demo (maven)

主线程随机抽一个10以内的整数，然后送入整数管道，死循环，且每次循环后休眠若干ms

创建一个Fiber协程，死循环从整数管道里读取，如果读取到的数字不为空则打印出来

• maven依赖

• 找到自己maven包路径

  • 点进Fiber类，然后向上级找一只找到那个maven依赖quasar-core-0.7.10-jdk8.jar

  • 然后复制路径 copy path得到

    C:\Users\lenovo\.m2\repository\co\paralleluniverse\quasar-core\0.7.10\quasar-core-0.7.10-jdk8.jar
    

  • 把路径加入到运行参数

    -javaagent:C:\Users\lenovo\.m2\repository\co\paralleluniverse\quasar-core\0.7.10\quasar-core-0.7.10-jdk8.jar
    

  • 运行里有个edit configuration编辑配置，把上面的代码复制放到VM options
    
    

• 运行测试代码
