我不太了解per4j,因为我是新手,我正在尝试将perf4j计时添加到我的maven项目中。我通过查看一些示例创建了项目设置。
这是我的log4j.xml

当我使用StopWatch
运行示例主类时,我正在使用时间详细信息记录日志文件但是当我使用@Profiled
注释时,它无法创建计时器日志。它创建新的日志文件但文件将为空。
我的示例类如下所示:
import org.apache.log4j.Logger;
import org.perf4j.StopWatch;
import org.perf4j.aop.Profiled;
import org.perf4j.log4j.Log4JStopWatch;
public class Sampletest {
private final static Logger logger = Logger.getLogger(Sampletest.class);
@Profiled(tag= "email", logFailuresSeparately=false)
public void email(){
// StopWatch stopWatch = new Log4JStopWatch("email");
try {
Thread.sleep((long)(Math.random() * 1000L));
} catch (InterruptedException e) {
e.printStackTrace();
}
logger.info("email");
// stopWatch.stop();
}
@Profiled(tag = "phone")
private void phone(){
//StopWatch stopWatch = new Log4JStopWatch("phone");
try {
Thread.sleep((long)(Math.random() * 2000L));
} catch (InterruptedException e) {
e.printStackTrace();
}
logger.info("phone");
//stopWatch.stop();
}
public static void main(String[] args) {
logger.info("Welcome to Perf4j");
Sampletest obj = new Sampletest();
obj.email();
obj.phone();
}
}
任何人都可以告诉我使用@Profiled
anotation我做错了什么,当我使用StopWatch
时一切顺利。
