try-catch+thows异常范围说明

方式一：

        CatalogPO deleteTarget = null;
        /** 查询是否存在 **/
        deleteTarget = catalogMapper.findByCatalogId(catalogId);
        if (Objects.isNull(deleteTarget)) {
            log.warn("the delete catalog is not existed");
            throw new WhBuCatalogException(HttpStatus.INTERNAL_SERVER_ERROR, ErrorCode.SUFIX_DB_DELETE, "要删除的服务目录不存在");
        }
        /** 判断是不是是预置服务目录 **/
        if (deleteTarget.getPreseted() == 1) {
            log.warn("the preseted catalog is not allow delete");
            throw new WhBuCatalogException(HttpStatus.INTERNAL_SERVER_ERROR, ErrorCode.SUFIX_DB_DELETE, "预置服务目录不允许删除");
        }
        /** 判断服务目录是否有绑定的服务 **/
        Metadata metadata = new Metadata();
        metadata.setFilter(new TreeMap<>());
        metadata.getFilter().put("catalogId", catalogId.toString());
        metadata.setPaginationParam(new PaginationParam(1,1000,1000));
        List<WhBuService> services = catalogMapper.listBindedServices(metadata);
        if (CollectionUtils.isNotEmpty(services)) {
            log.warn("the catalog has bind service is not allow delete");
            throw new WhBuCatalogException(HttpStatus.INTERNAL_SERVER_ERROR, ErrorCode.SUFIX_DB_DELETE, "服务目录绑定有服务不允许删除");
        }
        try {
            List<Long> ids = findCatalogIdAndChildIds(catalogId);
