Java中“ org.apache.log4j.Logger”的奇怪行为

Question

我正在做Maven项目 。 我使用log4j做了一个日志。 但是它在给定文件中显示了一些starnge日志。 我试图理解为什么会出现这个奇怪的日志，但是我不明白。 请帮帮我，为什么这个不需要的行输入日志文件。

请帮助我删除它。

log.properties

# Define the root logger with appender file
log = /usr/home/log4j
log4j.rootLogger = DEBUG, FILE

# Define the file appender
log4j.appender.FILE=org.apache.log4j.FileAppender
log4j.appender.FILE.File=C:/Users/aMpliFieR/Desktop/log.txt

# Define the layout for file appender
log4j.appender.FILE.layout=org.apache.log4j.PatternLayout
log4j.appender.FILE.layout.conversionPattern=%m%n

我通过阅读此链接制作了此文件。

和代码是

public class test {
    static Logger log = Logger.getLogger( test.class.getName() );

    public static void func(String url1, String url2) throws  InterruptedException {
        Threqad.sleep(100000000);  // Here is some process that performs recursively
        log.info( url1 + "\n" + url2 + "\n"+ ((double)loading_time)/((double)1000)+ " seconds   " + ((double)parsing_time)/((double)1000) +  " seconds   "  + ((double)processing_time)/((double)1000) + " seconds\n\n\n\n" );
    }

    public static void main(String[] args) throws InterruptedException{
            for(int i = 0; i < 5; i++) { func("ANY URL1", "ANY URL2");  }
    }
}

Log.txt-（log.txt的某些起始行）

Answer 1

您将rootLogger设置为DEBUG ，这意味着使用Log4J的所有库的调试语句都将记录其调试语句。 这可能是您的代码中已被注释替换的部分// Here is some process that performs recursively

最好将rootLogger配置为记录INFO或更高版本，并且-如果您确实需要调试级日志记录-将此特定程序包的记录器配置为DEBUG ，请使用：

log4j.rootLogger = INFO, FILE
log4j.some.package = DEBUG

其中some.package是您的类的软件包。 但是，由于您当前正在登录信息级别，因此这并不是必须的。
