今天研究了下这个JDK的线程池实现，当有任务来的时候，他首先用corePoolSize的线程执行，用完了就把任务放
在队列里面排队，假如又排满了，这时才会启用新的超出corePoolSize大小的线程来执行，假如还是用完了
maximumPoolSize，这个时候就会采用RejectedExecutionHandler来执行相应的策略，
ThreadPoolExecutor.CallerRunsPolicy()这个策略是用ThreadPoolExecutor的执行线程或者说主线
程来执行任务（而不是线程池中的线程），任务多的话就相当于主线程阻塞了，src如下：
/**
* Executes task r in the caller's thread, unless the executor
* has been shut down, in which case the task is discarded.
* @param r the runnable task requested to be executed
* @param e the executor attempting to execute this task
*/
public void rejectedExecution(Runnable r, ThreadPoolExecutor e) {
if (!e.isShutdown()) {
r.run();
}
}
=======================
线程池类为
java.util.concurrent.ThreadPoolExecutor，常用构造方法为：
ThreadPoolExecutor(int
corePoolSize, int maximumPoolSize,
long keepAliveTime, TimeUnit
unit,
BlockingQueue workQueue,
RejectedExecutionHandler
handler)
corePoolSize： 线程池维护线程的最少数量
maximumPoolSize：线程池维护线程的最大数量
keepAliveTime： 线程池维护线程所允许的空闲时间
unit： 线程池维护线程所允许的空闲时间的单位
workQueue： 线程池所使用的缓冲队列
handler： 线程池对拒绝任务的处理策略
一个任务通过 execute(Runnable)方法被添加到线程池，任务就是一个 Runnable类型的对象，任务的执行方法就是 Runnable类型对象的run()方法。
当一个任务通过 execute(Runnable)方法欲添加到线程池时：
如果此时线程池中的数量小于corePoolSize，即使线程池中的线程都 处于空闲状态，也要创建新的线程来处理被添加的任务。
如果此时线程池中的数 量等于 corePoolSize，但是缓冲队列 workQueue未满，那么任务被放入缓冲队列。
如果此时线程池中的数 量大于corePoolSize，缓冲队列workQueue满，并且线程池中的数量小于maximumPoolSize，建新的线程来处理被添加的任 务。
如果此时线程池中的数 量大于corePoolSize，缓冲队列workQueue满，并且线程池中的数量等于maximumPoolSize，那么通过 handler所指定的策略来处理此任务。
也就是：处理任务的优先级为：
核心线程corePoolSize、任务队列 workQueue、最大线程maximumPoolSize，如果三者都满了，使用handler处理被拒绝的任务。
当线程池中的线程 数量大于 corePoolSize时，如果某线程空闲时间超过keepAliveTime，线程将被终止。这样，线程池可以动态的调整池中的线程数。
unit 可选的参数为java.util.concurrent.TimeUnit中的几个静态属性：
NANOSECONDS、 MICROSECONDS、MILLISECONDS、SECONDS。
workQueue我常用的 是：java.util.concurrent.ArrayBlockingQueue
handler有四个选择：
ThreadPoolExecutor.AbortPolicy()
抛 出java.util.concurrent.RejectedExecutionException异常
ThreadPoolExecutor.CallerRunsPolicy()
重 试添加当前的任务，他会自动重复调用execute()方法
ThreadPoolExecutor.DiscardOldestPolicy()
抛 弃旧的任务
ThreadPoolExecutor.DiscardPolicy()
抛弃当前的任务

这里要注意的是当其中一个线程（
thread-3
）抛出异常后，他就再没执行过任务，但他还是占着一个线程计数，所以在代码中，可能要try catch，不然随着时间流逝，可用线程会越来越少。
然后我修改了代码
@Override
public void run() {
System.out.println(task);
if(task.equals("51")){
throw new RuntimeException();
}
if(task.equals("61")){
throw new RuntimeException();
}
if(task.equals("71")){
throw new RuntimeException();
}
if(task.equals("81")){
throw new RuntimeException();
}
}
结果在线程不断减少，到了少于2个（corePoolSize）的时候，就会起新的线程，满足至少2个
假如修改corePoolSize 为1甚至为0的时候，在线程不断减少的情况，他只会保持一个线程
public void run() {
System.out.println(task);
if(task.equals("51")){
throw new RuntimeException();
}
if(task.equals("61")){
throw new RuntimeException();
}
if(task.equals("71")){
throw new RuntimeException();
}
if(task.equals("81")){
throw new RuntimeException();
}
if(task.equals("87")){
throw new RuntimeException();
}
}
}
