前言
呵呵 之前项目中会存在这样的一个情况
选择多个文件导入 : 假设选择多个文件(一般是十个以上), 偶尔会抛出如下异常, 呵呵 和 redis 相关, 但是看异常信息 RejectedExecutionException 抛出的地方 又是在 forkjoin 库里面
呵呵 这两者有什么关联呢?
这里就来看看, 呵呵 forkjoin 这部分的类库 有一些博大精深, 多久还得仔细看看, 说实话 看起来 还是很有难度
我这里 只是从解决问题的角度, 看了一些, 但是 但是还有很多不明白的地方
另外这部分类库的调试也很奇怪, 似乎是和其他的普通线程不太一样, 这部分的代码的调试 你看不到很大一部分的局部变量
另外 就算你断点是 suspend all, 然而 断点打上了之后 你会发现 还有一部分的线程 还在跑 ??
这个就有点神奇了, 呵呵 希望多久能够 了解一下 这个是什么情况
问题调试
在业务系统中 错误信息大致如下, 当然 实际情况是 在 redisTemplate 获取响应数据的时候, 抛出来的, 确实是 在 ForkJoin 库里面抛出来的
然后导致了业务系统这边 上传文件, 然后解析记录出错, 最终记录的错误信息为 “Unknown redis exception; nested exception is java.util.concurrent.RejectedExecutionException: Thread limit exceeded replacing blocked worker”, 但是实际上 这部分记录是期望可以正常解析的

... 21 more来到 RejectedExecutionException 里面打上一个断点, 调试一下, 堆栈信息如下
可以看出是在 ForkJoinPool. tryCompensate 里面似乎是尝试什么东西, pool 承载不了了, 因此 抛出了 RejectedExecutionException

呵呵 这里我之前是差点没有注意到 这里的 "this == common" 的判断, 因此 造成了一些 我的其他的疑惑, 呵呵 后面来看
单元测试
根据这里的一些情况, 我们大致构造 单元测试如下来 复现问题
必须是需要 parallelStream[默认基于 commonPool] 的 api 结合 CompletableFuture, 才能复现这个问题
呵呵 在我这里真实场景里面 AsyncCommand 是继承了 CompletableFuture 的, 呵呵 这个可是真的隐秘

at java.util.concurrent.ForkJoinWorkerThread.run(ForkJoinWorkerThread.java:157)并行度[parallelism]和单个线程 parallelStream 可以创建的线程的关系
并行度可以通过 java.util.concurrent.ForkJoinPool.common.parallelism 来进行配置
如下左边为 并行度 parallelism, 右边为 单个线程在 并行度为 $parallelism 的情况下, 可以在 ForkJoinPool 里面创建多个少个线程
默认情况下 parallelism 为你 cpu 的数量[common为 cpu的数量-1], 假设我们这里为 8个cpu, commonPool 的并行度为 7
new ForkJoinPool() 创建出来的 pool 并行度为 8
然后可以大致推测一下, 如果我们是 上传 8 个以上的文件的话, 那么 parallelStream 可能创建的线程数会超过 [parallelism + 256], 这时候可能会抛出 RejectedExecutionException
然后使用我们测试环境, 尝试了一下, 呵呵 果然是这样
// parallelism : 1 -> 1
// parallelism : 2 -> 8
// parallelism : 4 -> 16
// parallelism : 7 -> 32
// parallelism : 8 -> 32
// parallelism : 16 -> 64
解决方式
1. 将 parallelStream 修改成为 stream
这样是可以解决问题的, 但是 少了并行处理 似乎上传之后的相关业务处理慢了很多
2. 控制可以并发处理 parallelStream 的线程数量
呵呵 也就是控制能够同时 处理 parallelStream 的这部分业务代码的线程的数量, 使其不超过 commonPool 的限制就行
又或者是 调整 parallelism, 综合来看就是 调整 commonPool 可能创建的线程的数量
但是 这个只适用于临时处理问题, 对于 实际业务情况, 还需要结合实际情况来处理
3. 创建自定义的 ForkJoinPool
呵呵 当时我也很奇怪, 为啥 我创建了一个自己的 ForkJoinPool 然后不管并行度设置的是多少, 然后 导入都灭有这个问题了呢?
呵呵 知道今天 我把 pool 的相关信息打印出来, 然后 大致的比较了一下 commonPool 和 自定义的 ForkJoinPool
我发现 自定义的 ForkJoinPool 是可以增长到超过 [parallelism + 256], 呵呵
然后 再回来仔细看了一下 代码, 发现了这一个 "this == common" 的判断
原来是只有 commonPool 有这个校验, 所以在我们业务场景下面 抛出了 RejectedExecutionException
4. 如果是 parallelStream 里面的业务处理没有依赖关系, 这里的并发处理可以更新为普通的线程池来处理
如果是 parallelStream 里面的相关业务处理 灭有依赖关系, 完全是可以使用 普通的线程池 来处理业务的
使用普通的线程池的话 这样就可以控制线程的数量[资源]了, 更加友好一些吧, 避免创建了 大量的线程
5. 去掉 parallelStream 里面的业务代码使用到 CompletableFuture 的地方
问题的情况是由于基于 commonPool 的 parallelStream 的使用, 以及 parallelStream 里面的业务代码使用到了 CompletableFuture 导致的
上面的 处理方式3, 是去掉了 commonPool, 使用了自定义的 ForkJoinPool, 跳过了 jdk 对于 commonPool 的限制
上面的 处理方式4, 是去掉了 parallelStream, 那么这里 的处理方式就是 避免在 parallelStream 里面使用 CompletableFuture 相关 api
至于实际如何处理, 还得结合你的实际的业务情况, 以上仅供参考
奇怪的调试
1. 旁边变量面板 居然无法解析 tc, pc 等局部变量
2. 暂停所有线程的断点, 居然还有一部分线程在执行?
