我正在尝试使用AWS docs中描述的Log4J2日志记录:

https://docs.aws.amazon.com/lambda/latest/dg/java-logging.html#java-wt-logging-using-log4j2.8

<?xml version="1.0" encoding="UTF-8"?>
<Configuration packages="com.amazonaws.services.lambda.runtime.log4j2.LambdaAppender">
  <Appenders>
    <Lambda name="Lambda">
      <PatternLayout>
          <pattern>%d{yyyy-MM-dd HH:mm:ss} %X{AWSRequestId} %-5p %c{1}:%L - %m%n</pattern>
      </PatternLayout>
    </Lambda>
  </Appenders>
  <Loggers>
    <Root level="debug">
      <AppenderRef ref="Lambda" />
    </Root>
  </Loggers>
</Configuration>

错误 但是在运行lambda时出现以下错误:(我删除了下面的时间戳以提高可读性)

ERROR Error processing element Lambda ([Appenders: null]): CLASS_NOT_FOUND
ERROR Unable to locate appender "Lambda" for logger config "root"

试过 我确信,log4j的库和log4j-core,log4j-api,aws-lambda-java-log4j2并aws-lamda-java-core都在包中.
