java - FINE 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

我的类(class)

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();
....

尽管我的断点到达了 url.openConnection(); 行，但 Level.FINE 没有出现在我的控制台中。这是我看到的控制台:

为什么我没有看到自己的自定义日志记录？

将 log4j.rootLogger=FINE, stdout 更改为 log4j.rootLogger=INFO, stdout 确实从控制台隐藏了所有 DEBUG，所以我知道这个文件正在被解析。

Answer 1

替换

log4j.rootLogger=FINE, stdout

与

log4j.rootLogger=TRACE, stdout

并在此处查看:http://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/Level.html和 http://logging.apache.org/log4j/1.2/manual.html

第二个链接说:

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

TRACE,
DEBUG,
INFO,
WARN,
ERROR and
FATAL
