這是我10年來的第一個java程序。我試圖做格式化打印,而與Log4J日誌錯誤2.java中的log4j格式化打印
我的代碼是
import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;
public class Feeder {
private static final Logger logger = LogManager.getLogger(Feeder.class);
public static void main(String args[]) throws InterruptedException {
try {
for (int i = 0; i < 100; i++) {
logger.info("Hello World " + i);
Thread.sleep(4000);
int x = 100/0;
}
}
catch (Exception ex){
StackTraceElement var[] = ex.getStackTrace();
for(StackTraceElement s: var){
logger.error("Error in Filename = %s", s.getFileName());
logger.error("Error in Class = " + s.getClassName());
logger.error("Error in line number " + s.getLineNumber());
logger.error("Error in method " + s.getMethodName());
}
//logger.error(ex.);
logger.error(ex.getMessage());
}
}
}
日誌吐以下
03 Oct 2014 12:12:46,302 INFO com.bluepoint.Feeder - Hello World 0
03 Oct 2014 12:12:50,304 ERROR com.bluepoint.Feeder - Error in Filename = %s
如何獲得文件的名稱,而不是
%s
