示例：

@Test
	public void testException(){
		try {
			double theorynumDouble = Double.parseDouble(null);
		} catch (Exception e) {
			StackTraceElement[] stackTraceElements =e.getStackTrace();
            StackTraceElement stackTraceElementFirst = stackTraceElements[0];
            String className = stackTraceElementFirst.getFileName();
            String methodName = stackTraceElementFirst.getMethodName();
            String lineNum = stackTraceElementFirst.getLineNumber()+"";
            for(StackTraceElement ste : stackTraceElements){
				
				  if((this.getClass().getName()+".java").equals(ste.getFileName())){ 
					  methodName += "/"+ste.getMethodName(); 
					  lineNum += "/"+ste.getLineNumber(); 
					  className += "/"+ste.getFileName();
					  break;
				 }
            }

            String errorMsg = "异常信息:"+e.getMessage()+"。异常类："+className+"。异常方法："+methodName+"。异常行号："+lineNum;
            System.out.println(errorMsg);
            
		}
	}

效果：
