推荐答案

试试这个样本，首先你需要两个这样的属性文件;

Try this sample, first you need two properties files likes this;

commons-logging.properties 放在应用程序的类路径中。此文件的内容应如下所示：

commons-logging.properties that put in your application's classpath. The contents of this file should look like:

    org.apache.commons.logging.Log=org.apache.commons.logging.impl.Jdk14Logger

除了Jdk14Logger之外，您还可以使用Log4j记录器。需要第二个自定义属性文件。示例 log-config.properties 如下所示：

You can also use Log4j logger besides Jdk14Logger.And need second custom properties file.For example log-config.properties looks like this:

    # The following creates two handlers
    handlers=java.util.logging.ConsoleHandler, java.util.logging.FileHandler
    # Set the default logging level for the root logger
    .level=SEVERE
    # log level for the "com.example" package
    sample.logging.level=FINE
    # Set the default logging level
    java.util.logging.ConsoleHandler.level=ALL
    java.util.logging.FileHandler.level=FINE
    # Set the default formatter
    java.util.logging.ConsoleHandler.formatter=java.util.logging.SimpleFormatter
    java.util.logging.FileHandler.formatter=java.util.logging.SimpleFormatter
    # Specify the location and name of the log file
    java.util.logging.FileHandler.pattern=D:/temp/log/test.log

这是示例测试类

     public class TestLog {

     private static Log log = LogFactory.getLog(TestLog.class);
     public static void main(String[] args) {
          log.info("Testing Info Message.");
              if (log.isDebugEnabled()) {
                  log.debug("Testing Debug Message.");
          }
        }
     }

这是使用的示例包结构eclipse;

This is sample package structure using eclipse;

并在VM参数下添加TestLog类的编辑配置，如下所示;

And add TestLog class's Edit Configuration under VM arguments likes this;

  -Djava.util.logging.config.file=/D:/dev/workspace/LoggingTest/bin/log-config.properties(your properties file path)

然后运行，你可以在D下找到你的日志文件：/temp/log/test.log

And run then you can find your log file under D:/temp/log/test.log
