Java LogRecord setSourceMethodName()用法及代码示例

java.util.logging.LogRecord的setSourceMethodName()方法用于设置据称发出日志请求的方法的名称。必须通过此方法设置logRecord中用于记录目的的源方法名称。

用法:

public void setSourceMethodName(String sourceMethodName)

参数：此方法接受sourceMethodName作为参数，这是源方法的名称。也可以为null。

返回：此方法不返回任何内容。

以下示例程序旨在说明setSourceMethodName()方法：
示例1:

// Java program to illustrate 
// setSourceMethodName() 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 source method 
        logRecord 
            .setSourceMethodName( 
                "MyFirstSourceMethod"); 
  
        // print the method name 
        System.out.println( 
            "Source method Name = "
            + logRecord.getSourceMethodName()); 
    } 
}

输出：

Source method Name = MyFirstSourceMethod

示例2:

// Java program to illustrate 
// setSourceMethodName() 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.INFO, 
                            "GFG Logger"); 
  
        // set a method from ArrayList class 
        // as source method 
        logRecord.setSourceMethodName( 
            ArrayList 
                .class
                .getMethods()[0] 
                .getName()); 
  
        // print the method name 
        System.out.println( 
            "Source method Name = "
            + logRecord.getSourceMethodName()); 
  
        // now set null as method name 
        logRecord.setSourceMethodName(null); 
  
        // print the method name 
        System.out.println( 
            "Now new Source method Name = "
            + logRecord.getSourceMethodName()); 
    } 
}

输出：

Source method Name = add
Now new Source method Name = null
