I have POJO like where I have a BigDecimal field:

public class Foo implements Serializable {

   private BigDecimal amount;
}

I want to have the BigDecimal value up to 2 decimal place only. Is there any annotation exist using which I can directly change it's value at the field level itself? I cannot change it's type as well.

ObjectMapper尽管它可以通过 getter在应用程序内完成。

我正在使用CompletableFuture,并对异常处理有疑问.

我有这样的代码,如果任何validate()或process()方法抛出异常,那么它由ExceptionHandler处理.但是,当我像这样使用CompletableFuture时,抛出的异常包含在CompletionException中.我可以知道如何确保在那里调用我的ExceptionHandler而不是获得CompletionException？

CompletableFuture<Response> response = CompletableFuture
                .supplyAsync(() -> {
                    validationService.validate(request);
                    return myService.process(request, headers);
                });

在我现有的应用程序中使用 Tomcat 9 设置采用 openjdk 8 时，出现以下错误

它与 Oracle JDK 一起工作正常，我对 openjdk 有什么遗漏吗？
