[英]RxJava Observable Single show current thread
I'm trying to understand how observable works and I'd like to show the current thread to get a better understanding. 我试图了解可观察的工作原理,并且我想展示当前线程以更好地理解。 The whole app is built with java 8 and make use of lambda expressions.
整个应用程序是使用Java 8构建的,并使用了lambda表达式。 No having much experience with it I'm finding some troubles to show my current thread in an expression like this:
没有足够的经验,我发现在这样的表达式中显示当前线程有一些麻烦:
.subscribeOn(Schedulers.io())
.observeOn(Schedulers.computation())
.flatMap(..... -> {
I like to put something like this: 我喜欢这样写:
log.info("Current Thread:", Thread.currentThread().name)
But I couldn't find a way to do it as subscribeOn(Schedulers.io()) and observeOn(Schedulers.computation()) return and Single and there is no way to put something like this: 但是我找不到办法做到这一点,因为subscribeOn(Schedulers.io())和observeOn(Schedulers.computation())返回并成为Single,因此无法放置这样的内容:
.subscribeOn(Schedulers.io())
.log.info("Current Thread:", Thread.currentThread().name)
.observeOn(Schedulers.computation())
.log.info("Current Thread:", Thread.currentThread().name)
.flatMap(..... -> {
Thanks 谢谢
You are trying just to log the current Thread, correct? 您正在尝试仅记录当前线程,对吗?
Just use map
for log and return the same value: 只需使用
map
作为日志并返回相同的值即可:
.subscribeOn(Schedulers.io())
.map(it -> {
log.info("Current Thread:", Thread.currentThread().name)
return it;
})
.observeOn(Schedulers.computation())
.map(it -> {
log.info("Current Thread:", Thread.currentThread().name)
return it;
})
.flatMap(..... -> {
