public void doExecute(HttpServletRequest request) throws Throwable {

imp.readExcel(filePath, 1);//文件路径、忽略行数

String sql = "insert into t_label_info values ('"

setSqlParameter(1, contact_way);

boolean flag = updateSql();
System.out.println(flag);
if(!flag){
throw new OurException("自定义异常！");
}
}
} catch (Exception e) {
e.printStackTrace();
throw e;
} finally{
}
flag返回false，这个怎么不抛出自定义异常？老师抛出updateSql()这个异常。
------解决方案--------------------
你try catch定义的是捕获所有的异常，自定义异常抛出的异常被捕获到了，此时抛到上层的异常为
catch块里的throw e;
