Java中的 LogRecord setThreadID() 方法及示例

Java.util.logging.LogRecord的setThreadID()方法用于设置消息来源线程的标识符。此方法有助于识别生成记录器消息的线程。

句法：

public void setThreadID(int threadID)

参数：该方法接受threadID ，它是整数类型的线程ID。

Return ：此方法不返回任何内容。

下面的程序说明了 setThreadID() 方法：
方案一：

// Java program to illustrate
// setThreadID() method
  
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.SEVERE,
                            "Hello Logger");
  
        // set Thread ID
        logRecord.setThreadID(53677);
  
        // print Thread ID
        System.out.println(
            "Thread ID = "
            + logRecord.getThreadID());
    }
}

输出：

Thread ID = 53677

方案二：

// Java program to illustrate
// setThreadID() method
  
import java.util.logging.Level;
import java.util.logging.LogRecord;
  
public class GFG {
  
    public static void main(String[] args)
    {
  
        // start the Thread
        Thread1 thread1 = new Thread1();
        thread1.start();
  
        // Create LogRecord object
        LogRecord logRecord
            = new LogRecord(Level.SEVERE,
                            "Hello Logger");
  
        // set Thread ID
        logRecord.setThreadID((int)thread1
                                  .getId());
  
        // print Thread ID
        System.out.println(
            "Thread ID = "
            + logRecord.getThreadID());
    }
}
  
class Thread1 extends Thread {
    public void run()
    {
        System.out.println("Thread is running...");
    }
}

输出：

Thread is running...
Thread ID = 8
