Java中的 LogRecord getInstant() 方法及示例
Java.lang.reflect.LogRecord的getInstant()方法用于获取事件发生的这一时刻,这有助于即时记录日志事件。
句法:
public Instant getInstant()
参数:此方法不接受任何内容。
Return :此方法返回事件发生的时刻。
下面的程序说明了 getInstant() 方法:
方案一:
// Java program to illustrate getInstant() method
import java.time.Instant;
import java.util.logging.Level;
import java.util.logging.LogRecord;
public class GFG {
public static void main(String[] args)
{
// Create LogRecord object
LogRecord logRecord = new LogRecord(
Level.parse("800"),
"Hi Logger");
logRecord
.setInstant(
Instant.parse(
"1994-04-12T11:54:23.89Z"));
// get the instant time
Instant instant = logRecord.getInstant();
System.out.println("Event Time = "
+ instant.toString());
}
}
输出:
Event Time = 1994-04-12T11:54:23.890Z
方案二:
// Java program to illustrate getInstant() method
import java.time.Instant;
import java.util.logging.Level;
import java.util.logging.LogRecord;
public class GFG {
public static void main(String[] args)
{
// Create LogRecord object
LogRecord logRecord = new LogRecord(
Level.parse("800"),
"Hi Logger");
logRecord.setInstant(Instant.now());
// get the instant time
Instant instant = logRecord.getInstant();
System.out.println("Event Time = "
+ instant.toString());
}
}
输出:
Event Time = 2019-10-20T19:41:57.803594Z
