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
