Spring的InvalidDataAccessApiUsageException的怪异行为在同一catch块中被调用两次

Question

我在下面的服务方法中创建了company数据。 Company与1:1具有CompanyType关系，company具有固定的一组值，并且无法插入更多值。这是一个只读表。因此，对于以下方法，我将错误的值（在DB中不存在）传递给InvalidDataAccessApiUsageException。当然public Company create(Company company) { Company createdCompany = null; try { company.setUser(userDao.findByEmail("abc@gmail.com") .orElseThrow(() -> new AccessDeniedException("You are not authenticated for this operation"))); createdCompany = companyDao.save(company); } catch (InvalidDataAccessApiUsageException ex) { // will be thrown if the company-type provided doesn't exist. // LOGGER.error(ex.getMessage()); LOGGER.error("*********************************************************"); throw new BadRequestException("Selected company type/category doesn't exist"); } return createdCompany; } 将在Spring之前抛出。但是我注意到catch块被调用了两次。这不是奇怪的行为吗？
