java - slf4j 与 jdk14 正在将 INFO 消息记录到 stderr

Question

我正在尝试通过 jdk14 来掌握 slf4j。奇怪的是，一些 INFO 级别的消息出现在 stderr 中。

我正在使用以下命令执行 jar

java -Djava.util.logging.config.file=./src/main/resources/logging.properties -jar ./target/adwordsConnectorV2-account.jar

我确信它们是 INFO 级别，因为当我将属性 java.util.logging.ConsoleHandler.level 设置为 ALL 时，消息会显示，但是当它被设置为SEVERE，它们不会显示。

请有人告诉我为什么他们可能会记录到 stderr 而不是 stdout？

谢谢

org.slf4j

slf4j-api = 1.7.7
slf4j-jdk14 = 1.7.7

以下是记录到 stderr 的内容:

编辑:这是logging.properties中的内容:

# from http://stackoverflow.com/questions/5416769/how-to-configure-the-jdk14-loggings-pattern
handlers = java.util.logging.ConsoleHandler
java.util.logging.ConsoleHandler.level = ALL
java.util.logging.ConsoleHandler.formatter = java.util.logging.SimpleFormatter
java.util.logging.SimpleFormatter.format = [%1$tc] %4$s: %2$s - %5$s %6$s%n

Answer 1

我在 stderr 上看到消息，因为这是 ConsoleHandler 使用的目标 - 请参阅 ConsoleHandler javadoc here

下面的文章展示了如何重定向输出，但这在某种程度上避免了问题 How do I change java logging console output from std err to std out?

我决定改用 log4j as recommended by the google adwords team
