线程 - java 进程通信问题

Question

现在有这样一个场景。

有一个jar在多线程运行，每个线程里都有自己的局部变量累加器 long count;

现在我需要通过一个spring的web project获取每个线程的count值，并且通过highcharts绘制出图形

请问这个独立jar的各自线程中的count局部变量，如何能被spring拿到？

自己想到的几个方法：

1.NIO的管道通信，PipedInputStream、PipedOutputStream

2.Thrift RPC服务

3.netty的服务

有没有可行的解决方案？

Answer 1

According to my understanding, you need inter-process communication, right?
Thrift and Netty you mentioned are both acceptable.
Or you can also use a message queue. Each jar package acts as a producer and submits count as a message to the queue, and then Your Spring Web project can retrieve the count value from the queue.

Answer 2

No need.
Get data directly from count使用map结构存放在redis中就ok了。hightcharts渲染时直接从redis.
The structure is as follows.

counter
    |
    | key1: v1`
    | key2: v2
