我们可以在出现异常的try块中获取LineNumber和ColumnNumber

问题描述

我有下面的代码，我可以打印出完整类，类名，方法名，发生错误。

I have the below code with which i am able to print the fullclassname,classname,methodname, at which error occured.

此外，我可以打印行数字，但打印的行号是变量LineNumber被初始化的行。

Also, I am able to print Line-Number but the Line-Number printed is the line at which the variable "LineNumber" is initialized.

如何在try块中打印确切的LineNumber和ColumnNumber，错误发生？

How can i print the exact LineNumber and ColumnNumber in try block at which error occured?

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);

}

推荐答案

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;
    }



}
