java - 捕获Spring数据异常

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);
  }

有时我会遇到异常(exception):

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

我需要捕获这个异常。我该怎么做？

Answer 1

您将其捕获为任何异常。不过我建议你还是捕获 DataIntegrityViolationException来自 Spring 框架，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
