我有下面的代码,我可以用它打印出发生错误的完整类名,类名,方法名。

另外,我能够打印Line-Number,但是打印的Line-Number是初始化变量“LineNumber”的行。

如何在出现错误的try块中打印确切的LineNumber和ColumnNumber?

try
{
    SQL Query
}
catch(Exception e)
{
   String fullClassName = Thread.currentThread().getStackTrace()[1].getClassName();
   String className = fullClassName.substring(fullClassName.lastIndexOf(".") + 1);
   String methodName = Thread.currentThread().getStackTrace()[1].getMethodName();
   int lineNumber = Thread.currentThread().getStackTrace()[1].getLineNumber();

     JOptionPane.showMessageDialog(null,fullClassName+"--"+className+"--"+methodName+"--"+lineNumber,"Error In Moving data from table1 to table2",JOptionPane.ERROR_MESSAGE);

}

最佳答案

public class ExceptionHandler {

    /**
     * @param args
     */
    public static void main(String[] args) {

        try {
            String str = getString();
            if(str.isEmpty()){
                System.out.println("error");
            }
        } catch (Exception e) {
            StackTraceElement[] elements = e.getStackTrace();
            for (int iterator=1; iterator<=elements.length; iterator++)
                   System.out.println("Class Name:"+elements[iterator-1].getClassName()+" Method Name:"+elements[iterator-1].getMethodName()+" Line Number:"+elements[iterator-1].getLineNumber());
        }
    }

    private static String getString() {
        jhgfjkhgjh();
        return null;
    }

    private static void jhgfjkhgjh() {
        gfdhdfghdg();
    }

    private static void gfdhdfghdg() {
        sdfytusdgsfd();
    }

    private static void sdfytusdgsfd() {
        throw null;
    }



}

关于java - 我们可以在发生异常的try块中获取行号和列号吗,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/14235687/
