threadpoolexecutor 主要有以下幾個引數:
public threadpoolexecutor(int corepoolsize,
int maximumpoolsize,
long keepalivetime,
timeunit unit,
blockingqueueworkqueue,
threadfactory threadfactory,
rejectedexecutionhandler handler)
複製**
maximumpoolsize 最大執行緒數
keepalivetime timeunit 執行緒空閒時間
workqueue 任務佇列
threadfactory 建立執行緒的工廠
private static class customthreadfactory implements threadfactory
@override
public thread newthread(@nonnull runnable runnable)
if (thread.getpriority() != thread.norm_priority)
return thread;}}
複製**
下面是自定義實現，相當於discardpolicy，只列印異常資訊
private static class customrejectedexecutionhandler implements rejectedexecutionhandler
@override
public void rejectedexecution(runnable r, threadpoolexecutor e)
}複製**
private final threadpoolexecutor mexecutor;
private threadpoolmanager
() public void executor(@nonnull runnable runnable)
複製**
ThreadPoolExecutor引數設定
1 首先預估系統負載，需要以下幾個值 tasks 每秒的任務數，假設為50 100 tasktime 每個任務花費時間，假設為0.1s responsetime 系統允許容忍的最大響應時間，假設為30s 2 計算 1 corepoolsize 每個任務需要tasktime秒處理，則每個執行緒每秒可處...

ThreadPoolExecutor使用小結
記錄一下那幾個引數的理解，網上說了亂七八糟，詳細看參考文件，很詳細很明白，沒什麼好說的。corepoolsize,maximumpoolsize,keepalivetime keepalivetime workqueue queue blocksize 執行執行緒後，會判斷數量是否超出corepoo...
