SpringBoot和SpringPropertys logging.path

Question

当前，我们的application.properties中有一个logging.path属性

，如果在我们的application.properties文件中我们进行硬编码

，则此方法很好

logging.path='logs/location'

但是如果我们尝试将其外部化

logging.path=${service.logging.path}

我们收到有关找不到春天占位符的错误

java.lang.IllegalArgumentException: Could not resolve placeholder 'request-routing-service.logging.path' in value "${request-routing-service.logging.path}"

它只是拥有

logging.path=${external.property}

我的日志文件中的问题是我不必尝试使用它。
