# 设置日志级别为INFO
log4j.rootLogger=INFO, stdout

# 输出到控制台
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public class HelloWorld {
    private static final Logger logger = LoggerFactory.getLogger(HelloWorld.class);

    public static void main(String[] args) {
        logger.info("Hello World");
    }
}
