java - 捕获特定异常子类型的列表，而不是未检查的异常

Question

如何确定对未经检查的异常使用什么异常？例如

    @Override
    protected void doPost(SlingHttpServletRequest request, SlingHttpServletResponse response) {
        LOG.info("Inisde FarmersLegalAuditJsonDataServlet do post method");
        try {
            String auditKey = request.getParameter("auditKey") != null ? request.getParameter("auditKey") : StringUtils.EMPTY;
            LOG.info("auditKey:{}",auditKey);
            
            if (StringUtils.isNotEmpty(auditKey)) {     
                //Calling service to serach in the repository
                String redirectPath = farmersLegalAuditSearchService.getJsonFilePath(auditKey, request);
                LOG.info("redirectPath:{}",redirectPath);
                
                if(StringUtils.isNotEmpty(redirectPath) && !StringUtils.equalsIgnoreCase(redirectPath, "EMPTY_RESULT")) {
                    response.sendRedirect(redirectPath);
                } else if(StringUtils.isNotEmpty(redirectPath) && StringUtils.equalsIgnoreCase(redirectPath, "EMPTY_RESULT")) {
                    response.getWriter().print("No results found");
                } else {
                    response.getWriter().print("There is some backend issue. Please try later.");
                }
            } else {
                LOG.info("auditKey is empty/null");
                response.getWriter().print("There is some backend issue. Please try later.");
            }
        } catch (IOException ioe) {
            LOG.error("IOException:", ioe);
        } catch(Exception ex) {
            LOG.error("Exception:",ex);
        }
    }

对于catch(Exception ex) {LOG.error("Exception:",ex); }SonarQube 不想要通用异常，请注意当我删除 catch(Exception E) 时，项目构建得很好，它甚至需要异常，如果需要，我应该使用哪一个？
