问题 I'd like to modify how my application works depending on whether the --debug switch is present or not. I tried this in my @Configuration file: @Value("\${debug}") lateinit var debug: String but Spring says Could not resolve placeholder 'debug' in value "${debug}" How can I query the state of the --debug option? 回答1: The most robust way to check for debug mode is to query the Environment . This will allow you to detect that the mode has been enabled whether that's been done via a command line

问题 Is there an equivalent to JVM's Thread.sleep() in pure Kotlin for use on MPP projects? This could be implemented on each platform using expected , but I am asking about a solution that does not use that method. 回答1: This can be done using coroutines. For example: runBlocking { println("Wait for 5sec") delay(5000) println("Done waiting for 5sec") } 来源： https://stackoverflow.com/questions/55223336/how-to-make-a-delay-in-kotlin-multiplatform-pure-kotlin

问题 Import kotlinx greyed out I think i try nearly everything. Reinstall Android Studio, Invalide Cache, new Project same Problem. i just can't find the Solution 回答1: Can you try File | Invalidate Caches / Restart Deleting .idea folder Clean Re-import the project OR just remove apply plugin: 'kotlin-android-extensions' , sync gradle plugin and then I added it again. 回答2: Check "build.gradle(:app)" file, plugins { id 'com.android.application' id 'kotlin-android' } if kotlin extension is missing,
