Question

我试图用jdk14抓住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，会显示消息，但是当它设置为SEVERE时，它们就会消失。 ; t show。

请有人告诉我为什么他们可能会登录到stderr而不是stdout？

由于

本

com.google.api的广告

ads-lib = 1.30.0
adwords-axis = 1.30.0

org.slf4j

slf4j-api = 1.7.7
slf4j-jdk14 = 1.7.7

以下是记录到stderr的内容：

编辑：以下是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上看到了消息，因为这是ConsoleHandler使用的目标 - 请参阅ConsoleHandler javadoc here

以下文章介绍了如何重定向输出，但这有点避免了问题 How do I change java logging console output from std err to std out?

我决定转而使用log4j而不是as recommended by the google adwords team

带有jdk14的slf4j正在将信息消息记录到stderr
