java - 抛出异常后不会正确捕获 block

Question

我在 jdbctemplate 中使用 batchupdate 插入时试图处理重复键异常。

虽然我尝试使用重复键插入，但它会进入服务方法中的异常捕获 block 而不是 BatchUpdateException 捕获 block 。我将堆栈跟踪作为 BatchUpdateException，但它仍然会转到异常捕获 block 。有什么想法吗？

代码如下:

服务等级:

    try {
        auctionDM.insertSelctedAuctionItem(salesBean, Constants.VESL_CODE);
    } catch (BatchUpdateException bue) {
        logger.error(" Duplicate item -", bue);
        throw new MyException(ExceptionCodes.DB_DUPLICATE_ITEM);
    } catch (SQLException se) {
        logger.error(" SQL Exception occured -", se);
        throw new MyException(ExceptionCodes.DB_ERROR);
    } catch (LegacyException e) {
        logger.error(" AppException occured -", e);
        throw new MyException(ExceptionCodes.DB_ERROR);
    } catch (Exception e) {
        logger.error(" SystemException occured -", e);
        throw new MyException(ExceptionCodes.DB_ERROR);
    }

数据管理类:

public int[] insertSelctedAuctionItem(SalesBean salesBean, String veslCode) throws SQLException {

      //code
      return getJdbcTemplate().batchUpdate(sqlQuery.toString(), batchParams);
}

堆栈跟踪:

Spring 将 SQLExceptions 包装在一个名为 DataAccessException 的 RuntimeException 类中。因此，您的 insertSelectedAuctionItem 抛出一个 RuntimeException，然后由 Exception catch 子句处理。
