我在玩 Spring react 器,我看不出 concat
和 merge
运算符之间有任何区别
这是我的例子
@Test
public void merge() {
Flux<String> flux1 = Flux.just("hello").doOnNext(value -> {
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
e.printStackTrace();
}
});
Flux<String> flux2 = Flux.just("reactive").doOnNext(value -> {
try {
Thread.sleep(2000);
} catch (InterruptedException e) {
e.printStackTrace();
}
});
Flux<String> flux3 = Flux.just("world");
Flux.merge(flux1, flux2, flux3)
.map(String::toUpperCase)
.subscribe(System.out::println);
}
@Test
public void concat() {
Flux<String> flux1 = Flux.just("hello").doOnNext(value -> {
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
e.printStackTrace();
}
});
Flux<String> flux2 = Flux.just("reactive").doOnNext(value -> {
try {
Thread.sleep(2000);
} catch (InterruptedException e) {
e.printStackTrace();
}
});
Flux<String> flux3 = Flux.just("world");
Flux.concat(flux1, flux2, flux3)
.map(String::toUpperCase)
.subscribe(System.out::println);
}
两者的行为完全相同。有人可以解释这两种操作之间的区别吗?
最佳答案
关于java - Spring Reactor 合并与 Concat,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/48478420/
