Groovy 线程

1、Groovy中，调用Thread的静态方法start来创建线程。

def printThreadInfo() {Thread currentThread = Thread.currentThread()println "Current Thread is ${currentThread}"}printThreadInfo()Thread.start {printThreadInfo();}

返回
Current Thread is Thread[main,5,main]
Current Thread is Thread[Thread-1,5,main]

2、sleep方法可以用来暂停当前操作。

startTime = System.currentTimeMillis()new Object().sleep(2000)endTime = System.currentTimeMillis()println "Thread last ${endTime - startTime} MilliSeconds"

返回
Thread last 2001 MilliSeconds

3、如果sleep方法返回true，inturrpt方法可以打断sleep。

def interruptSleep(name, flag) {thread = Thread.start(name) {startTime = System.currentTimeMillis()new Object().sleep(2000) {flag}endTime = System.currentTimeMillis()Thread currentThread = Thread.currentThread()println "${currentThread} last ${endTime - startTime} MilliSeconds"}thread.interrupt()}interruptSleep("thread1", true)interruptSleep("thread2", false)

返回
Thread[thread1,5,main] last 2 MilliSeconds
Thread[thread2,5,main] last 2001 MilliSeconds

4、Daemon线程在主线程退出后不再运行。

Thread.start {    startTime = System.currentTimeMillis()    new Object().sleep(2000)    endTime = System.currentTimeMillis()    println "Thread last ${endTime - startTime} MilliSeconds"}Thread.startDaemon {    startTime = System.currentTimeMillis()    new Object().sleep(3000)    endTime = System.currentTimeMillis()    println "Daemon Thread last ${endTime - startTime} MilliSeconds"}

返回
Thread last 2002 MilliSeconds
