block()报错
WebFlux中,如果是Mono/Flux.map()或者其他方法体是属于NonBlocking线程,如果在NonBlocking线程中再调用阻塞方法(block()等)会报错
static final class NonBlockingThread extends Thread implements NonBlocking {
public NonBlockingThread(Runnable target, String name) {
super(target, name);
}
}
public static void main(String[] args) throws InterruptedException {
Thread th = new NonBlockingThread(new Runnable() {
@Override
public void run() {
if (Thread.currentThread() instanceof NonBlocking){
System.out.println("====");
}
System.out.println(Mono.create(
monoSink -> {
monoSink.success("sasa");
}
).block());
}
}, "sasa");
th.start();
Thread.sleep(5000L);
}
修复方式
用JUC,如果是webflux 编程可以使用Mono.delay + publishOn(Schedulers.boundedElastic())
public static void main(String[] args) throws InterruptedException {
Thread th = new NonBlockingThread(new Runnable() {
@Override
public void run() {
if (Thread.currentThread() instanceof NonBlocking){
System.out.println("====");
}
CountDownLatch countDownLatch = new CountDownLatch(1);
AtomicReference reference = new AtomicReference<>();
Mono.create(
monoSink -> {
monoSink.success("sasa");
}
).publishOn(Schedulers.boundedElastic()).subscribe(
s->{
reference.set(s);
countDownLatch.countDown();
}
);
try {
countDownLatch.await();
} catch (InterruptedException e) {
e.printStackTrace();
}
System.out.println(reference.get());
}
}, "sasa");
th.start();
Thread.sleep(5000L);
}
