PlayFramework 在使用 CompletableFutures 和 java 时传递执行上下文
PlayFramework passing execution context when using CompletableFutures and java
在 this section of the documentation 中,他们解释了如何为 scala
执行此操作
Future {
// Some blocking or expensive code here
}(myExecutionContext)
当你使用 CompletableFuture
时,这相当于什么:
CompletableFuture.supplyAsync(() -> {
// Some blocking or expensive code here
}, someCustomExecutor);
我们如何确保在使用 java
和 CompletableFuture
时上下文可用?
CompletableFuture.supplyAsync(() -> {
// Some blocking or expensive code here
}, play.libs.concurrent.HttpExecution.defaultContext());
来自the docs:
ExecutionContexts that preserve the current thread's context ClassLoader and Http.Context.
