Java中的 LogRecord getSourceMethodName() 方法及示例

Java.lang.reflect.LogRecord的getSourceMethodName()方法用于获取据称发出日志请求的方法的名称。在 logRecord 中用于记录目的的源方法。

句法：

public String getSourceMethodName()

参数：此方法不接受任何内容。

返回：此方法返回源方法名称。

下面的程序说明了 getSourceMethodName() 方法：
方案一：

// Java program to illustrate
// getSourceMethodName() 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.parse("800"),
            "Hi Logger");
        logRecord.setSourceMethodName(
            "MyFirstSourceMethod");
  
        // get the source method name
        String sourceMethod
            = logRecord.getSourceMethodName();
  
        // print the method name
        System.out.println(
            "Source Method Name = "
            + sourceMethod);
    }
}

输出：

Source Method Name = MyFirstSourceMethod

方案二：

// Java program to illustrate
// getSourceMethodName() method
  
import java.util.logging.Level;
import java.util.logging.LogRecord;
import java.util.*;
  
public class GFG {
  
    public static void main(String[] args)
    {
  
        // Create LogRecord object
        LogRecord logRecord = new LogRecord(
            Level.parse("600"),
            "GFG Logger");
        logRecord.setSourceMethodName(
            ArrayList
                .class
                .getMethods()[0]
                .getName());
  
        // get the source method name
        String sourceMethod
            = logRecord.getSourceMethodName();
  
        // print the method name
        System.out.println(
            "Source Method Name = "
            + sourceMethod);
    }
}

输出：

Source Method Name = add
