Question

我尝试保留实体列表：

for (Charge charge : charges) {
      try {
        Charge savedCharge = saveCharge(charge);
      }catch (DataAccessException e){
        log.error(e.getMessage());
      }
    }

public Charge saveCharge(Charge charge){
    return chargesRepository.save(charge);
  }

有时候我会出胎：

Caused by: java.sql.SQLIntegrityConstraintViolationException: ORA-00001: the limitation of uniqueness has been violated

我需要抓住这个机会。我该怎么办？

您将其作为任何异常捕获。但是我建议您宁愿从Spring框架中了解DataIntegrityViolationException，因为Spring已经将SQL异常转换为更具体的异常：

try {
    Charge savedCharge = saveCharge(charge);
} catch (DataIntegrityViolationException e) {
    log.error(e.getMessage());
    // more error handling actions
} // more catch clauses

赶上Spring数据展示
