java - 无法提交 JPA 事务；嵌套异常 - 事务标记为 rollbackOnly

Question

我有服务类，并从我的服务类中定义的 plant() 方法调用方法 userPlanter.sow() 。

在执行服务类方法时遇到Transaction被标记为rollbackOnly异常。

请找到我的服务等级。

@Service
@Transactional(readOnly = true)
public class NurseryServiceImpl implements NurseryService {

@Autowired
private UserPlanter userPlanter;

@Transactional
public SeedStatus plant() {
SeedStatus result = new SeedStatus();
userPlanter.sow(result);
return result;
}

}

请找到我的组件类。

@Component
public class UserPlanter {
@Transactional(propagation = Propagation.REQUIRES_NEW)
public void sow(SeedStatus result) {
try {
  User[] users = readJson(getFilePath(), User[].class);
  String message = createIfNeeded(users);
  result.addStatus(message);
} catch (Exception exception) {
String message = String.format("An error occurred while seeding the users. Please inspect the server logs. %s", exception);
result.addStatus(message);
 }
}

在执行我的服务类方法 plant() 时遇到以下异常。

请找到完整的堆栈跟踪。

问题是:

您在 sow 方法 中捕获异常。该异常发生在您的 createIfNeeded 方法中，这可能是数据库访问。然后 Spring 将您的事务标记为要回滚。

但是，您不会通过捕获该异常来让该异常冒泡，因此您的 @Transactional 注释将导致 Spring 尝试并提交您的事务，即使它已被标记为要滚动返回。

最简单的修复方法是捕获并重新抛出异常，或者在@Transactional方法的外部捕获异常。
