如何避免Sonar的“保留堆栈跟踪”冲突？

Question

Sonar gives a major violation error ("Preserve Stack Trace") for the following code. Following method is used to throw an exception. What are the steps should I take to overcome this violation?

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

You've logged each exception; that should be enough as far as preserving information is concerned like below,

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

Or You should re throw the PhDashException if you can, because, you should be enough as far as preserving information is concerned

throw new PhDashException(pHDashExceptionMapper);
