Java中的 LogRecord setThrown() 方法及示例

Java.util.logging.LogRecord的setThrown()方法用于与日志事件关联的 throwable。这用于在 logRecord 中记录可用于记录消息的异常。

句法：

public void setThrown(Throwable thrown)

参数：此方法接受 throwable 作为参数，该参数是可抛出的对象。它也可以为空。

Return ：此方法不返回任何内容。

下面的程序说明了 setThrown() 方法：
方案一：

// Java program to illustrate setThrown() method
  
import java.io.IOException;
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 throwable object
        logRecord.setThrown(
            new IOException(
                "Error in Input"));
  
        // print the method name
        System.out.println(
            "throwable object Message = "
            + logRecord.getThrown()
                  .toString());
    }
}

输出：

throwable object Message = java.io.IOException: Error in Input

方案二：

// Java program to illustrate setThrown() method
  
import java.io.IOException;
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");
  
        // create a throwable object
        Exception exception
            = new ArithmeticException(
                "divide by 0");
  
        // set throwable object
        logRecord.setThrown(exception);
  
        // print the result
        System.out.println(
            "throwable object = "
            + logRecord.getThrown()
                  .toString());
    }
}

输出：

throwable object = java.lang.ArithmeticException: divide by 0
