工作者线程配置
##使用线程池
org.quartz.threadPool.class: org.quartz.simpl.SimpleThreadPool
## 线程数量
org.quartz.threadPool.threadCount: 15
## 设置工作者线程的优先级
org.quartz.threadPool.threadPriority: 5
org.quartz.threadPool.threadsInheritContextClassLoaderOfInitializingThread:
true
|
下面看一下SimpleThreadPool的源码 , 这是一个固定大小的线程池。
public
class
SimpleThreadPool
implements
ThreadPool {
/*
* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
*
* Data members.
*
* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
*/
// 初始化线程数，对应配置文件里面的threadCount
private
int
count = -
1
;
// 线程优先级
private
int
prio = Thread.NORM_PRIORITY;
// 线程是否停止
private
boolean
isShutdown =
false
;
//
private
boolean
handoffPending =
false
;
private
boolean
inheritLoader =
false
;
private
boolean
inheritGroup =
true
;
private
boolean
makeThreadsDaemons =
false
;
private
ThreadGroup threadGroup;
private
final
Object nextRunnableLock =
new
Object();
// 工作线程
private
List<WorkerThread> workers;
// 可用线程
private
LinkedList<WorkerThread> availWorkers =
new
LinkedList<WorkerThread>();
// 忙碌线程
private
LinkedList<WorkerThread> busyWorkers =
new
LinkedList<WorkerThread>();
private
String threadNamePrefix;
private
final
Logger log = LoggerFactory.getLogger(getClass());
private
String schedulerInstanceName;

该线程池主要是负责任务的执行，任务的触发是由一个主线程（QuartzSchedulerThread）来负责触发调度的，
