Flink广播变量Demo
说明：
Class Dataserver将侦听端口7777上的连接，并将每秒两次将1-6的随机数发送到任何已连接的sockets 。
StateServer类将侦听端口7778上的连接，并允许在stdin上输入整数。
BroadcastState将连接到两个sockets
运行：
构建jar：
mvn clean package
打开两个终端以启动两个服务器并观察它们的日志记录：
make dataserver
make stateserver
（如果系统没有make工具，请参阅Makefile以获取要使用的命令。）
可以通过在IDE中运行BroadcastState来运行Flink作业。由于作业正在使用PrintSinkFunction，因此管道的输出在日志中。 在运行状态服务器的终端中键入一个乘数，以查看正在处理的更新。 输出还将显示哪个Flink进程处理了该更新。 这取决于您系统中的内核数（在我的情况下为8）：
