FINE日志记录不记录

Question

log4j.properties

log4j.rootLogger=FINE, stdout 

log4j.appender.stdout=org.apache.log4j.ConsoleAppender 
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout 
log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %5p %t %c:%L - %m%n 

log4j.category.my.root.package=FINEST 

我的班级

public class MyClass { 
    private static final Logger logger = Logger.getLogger(MyClass.class.getName()); 


    public boolean download(String destinationPath) { 
     HttpURLConnection con = null; 
     int i; 

     try { 
      logger.log(Level.FINE, "Download URL {0}", new Object[] { url.toString()}); 
     con = (HttpURLConnection) url.openConnection(); 
     con.setInstanceFollowRedirects(true); 

     InputStream is = con.getInputStream(); 
.... 

尽管我断点到达url.openConnection();线，该Level.FINE并不在我的控制台显示出来。这里是我看到的控制台：

我怎么没有看到我自己的自定义日志？

将log4j.rootLogger=FINE, stdout更改为log4j.rootLogger=INFO, stdout确实会从控制台隐藏所有DEBUG，所以我知道该文件正在被解析。

Answer 1

更换

log4j.rootLogger=FINE, stdout 

与

log4j.rootLogger=TRACE, stdout 

并检查在这里：http://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/Level.html 和http://logging.apache.org/log4j/1.2/manual.html

第二个环节说：

Loggers may be assigned levels. The set of possible levels, that is: 

TRACE, 
DEBUG, 
INFO, 
WARN, 
ERROR and 
FATAL 

Answer 2

log4j的级别与Java Loggin Framework不同。

对于log4j的，所有可能的选项是：

• ALL
• TRACE
• DEBUG
• INFO
• WARN
• ERROR
• FATAL
• OFF
