java - 如何避免 Sonar 的 "preserve stack trace"违规？

Question

Sonar给出以下代码的严重违规错误(“保留堆栈跟踪”)。下面的方法用于抛出异常。我应该采取哪些措施来克服这种违规行为？

public void exceptionHandler(String exception) throws PhDashException {

    String exceptionMsg = exception.replaceAll("-", "_");

    ExceptionPhDash pHDashExceptionMapper = new ExceptionPhDash();
    try {
        pHDashExceptionMapper = new ObjectMapper().readValue(exceptionMsg, ExceptionPhDash.class);
    } catch (JsonParseException e) {
        LOGGER.info(e.getMessage());
    } catch (JsonMappingException e) {
        LOGGER.info(e.getMessage());
    } catch (IOException e) {
        LOGGER.info(e.getMessage());
    }
    throw new PhDashException(pHDashExceptionMapper.getMessage());
}

Answer 1

您已记录每个异常；就保存信息而言，这应该足够了，如下所示，

LOGGER.info("Unexpected Exception has occurred", e);     

或者，如果可以的话，您应该重新抛出PhDashException，因为就保留信息而言，您应该足够了

throw new PhDashException(pHDashExceptionMapper);
