我只希望一个线程同时修改一个策略，不同的策略可以同时修改。 像这样的代码：
private static ConcurrentHashMap<String, InfoCounter> policyNameLockSecond = new ConcurrentHashMap<String, InfoCounter>();
public void registerModiyRequest(String infoName) {
logger.info(" " + Thread.currentThread().getName() + " register :" + infoName);
synchronized (policyNameLockSecond) {
InfoCounter counter = policyNameLockSecond.get(infoName);
if (counter == null) {
counter = new InfoCounter(infoName);
policyNameLockSecond.put(infoName, counter);
}
counter.add();
logger.info(" " + Thread.currentThread().getName() + " counter :" + counter.count());
final long count = counter.getCounter().longValue();
logger.info(" " + Thread.currentThread().getName() + " policyName["
+ infoName + "] count = " + count);
if (count > 1) {
try {
logger.info(" " + Thread.currentThread().getName()
+ " wait ");
counter.getLock().lockInterruptibly();
} catch ( Exception e) {
e.printStackTrace();
logger.error("applyForModifyPolicy, policyNameLock is interrupted");
}
}
}
}
public void unregisterModifyinfoRequest(String infoName) {
logger.info(" " + Thread.currentThread().getName()
+ " unregister policyName: "+infoName);
InfoCounter counter = policyNameLockSecond.get(infoName);
counter.minus();
synchronized (counter) {
try {
final long count = counter.getCounter().longValue();
if (count < 1) {
logger.info(infoName
+ "'s hold count is 1, remove this lock");
policyNameLockSecond.remove(infoName);
} else {
logger.info("still has other thread apply this lock,"
+ count);
}
} catch (Exception e) {
e.printStackTrace();
logger.error("waitAvailableRequestTicket, requestQueueLock is interrupted");
} finally {
logger.info(" "+Thread.currentThread().getName()
+" release this lock");
counter.getLock().unlock();
}
}
}
private static class InfoCounter {
private final String infoName;
private final AtomicLong counter;
private final ReentrantLock lock;
public ReentrantLock getLock() {
return lock;
}
public AtomicLong getCounter() {
return counter;
}
public InfoCounter(final String name) {
this.infoName = name;
this.counter = new AtomicLong();
this.lock = new ReentrantLock();
}
public void add() {
counter.incrementAndGet();
}
public void minus() {
counter.decrementAndGet();
}
public long count(){
return counter.longValue();
}
}
在主函数
中运行代码时public static void main(String[] args) throws Exception {
ExecutorService executor1 = Executors.newFixedThreadPool(20 );
ExecutorService executor2 = Executors.newFixedThreadPool(20 );
for(int i = 0; i < 20 ; i ++){
executor1.submit( new Runnable(){
@Override
public void run(){
try {
configPolicyModifyLock.registerModiyRequest("123");
logger.info(" "+Thread.currentThread().getName() + " register policyName " + "123");
Thread.sleep(300000);
} catch( Exception e ) {
e.printStackTrace();
logger.error(e, e);
} finally {
logger.info(" "+Thread.currentThread().getName() + " unregister 123 ");
configPolicyModifyLock.unregisterModifyinfoRequest("123");
}
}
});
}
for(int i = 0; i < 20 ; i ++){
executor2.submit( new Runnable(){
@Override
public void run(){
try {
configPolicyModifyLock.registerModiyRequest("12");
logger.info(" "+Thread.currentThread().getName() + " register policyName " + "12");
} catch( Exception e ) {
logger.error(e, e);
e.printStackTrace();
} finally {
logger.info(" "+Thread.currentThread().getName() + " unregister 12 ");
configPolicyModifyLock.unregisterModifyinfoRequest("12");
}
}
});
}
}
它可以工作，但是当我在Web应用程序中使用它时，函数抛出IllegalMonitorStateException。
