Я создаю многопоточное приложение Spring Boot с использованием аннотаций Spring @EnableAsync и @Async.Когда я запускаю приложение с одним потоком (CorePoolSize 1, MaxPoolSize 1), все работает как положено.Когда я увеличиваю размер пула выше 1 в случаях, которые кажутся случайными, я получаю java.sql.SQLNonTransientException: [Amazon] JDBC Не все параметры заполнены. ошибка при вызовах Amazon AWS Redshiftбаза данных.
В ServiceProcessBean.java я автоматически подключил свой класс ProcessService (многопоточная работа, которую необходимо выполнить) и ShipmentDAO, который загружает список идентификаторов отгрузки, которые будут обработаны методом ProcessService.process (),код ниже.
@Component
public class ShipmentBatchBean {
private Logger logger = LoggerFactory.getLogger(this.getClass());
@Autowired
private ShipmentDAO shipmentDAO;
@Autowired
private ProcessService processService;
@Scheduled(
initialDelayString = "${executor.delay.initial}",
fixedDelayString = "${executor.delay.fixed}"
)
public void cronJob() throws InterruptedException, ExecutionException {
List<CompletableFuture<Boolean>> asyncResponse = new ArrayList<>();
logger.info("Starting cronJob() method");
try {
List<String> shipments = shipmentDAO.getAllShipmentsReadyForIeta();
logger.info("There are {} shipments to be processed in the data store",
shipments.size());
for(String shipment : shipments) {
asyncResponse.add(processService.process(shipment));
}
} catch (Exception ex) {
logger.error(ex.getMessage());
ex.printStackTrace();
}
CompletableFuture.allOf(asyncResponse.toArray(
new CompletableFuture[asyncResponse.size()]
)).join();
logger.info("Ending cronJob() method");
}
}
Наконец, в ProcessService мы автоматически подключаем несколько репозиториев и службу JSON и начинаем метод process () с аннотации @Async.См. Фрагмент кода ниже.
@Service
public class ProcessServiceBean implements ProcessService {
private Logger logger = LoggerFactory.getLogger(getClass());
@Autowired
private ShipmentDAO shipmentDAO;
@Autowired
private OssItemDAO ossItemDAO;
@Autowired
private OssHeaderDAO ossHeaderDAO;
@Autowired
private OssDataJsonServiceBean ossDataJsonServiceBean;
@Override
@Async
public CompletableFuture<Boolean> process(String shipmentId) {
Shipment shipment = null;
logger.debug("Retrieving from ieta_input (shipment id {})",
shipmentId);
try {
shipment = shipmentDAO.getOneBy(shipmentId);
} catch (SQLException e) {
logger.error("process of shipment {}) ended in error",
shipmentId,
};
return CompletableFuture.completedFuture(false);
}
code snipped for brevity.
Наконец, в ShipmentDAO у нас есть метод getOneBy (), который возвращает запрошенную запись об отправке.
@Override
public Shipment getOneBy(String shipmentId) throws SQLException {
Shipment shipment = null;
Connection conn = null;
String sql = "SELECT * FROM myschema.tablename WHERE shipmentid = ? LIMIT 1";
try {
conn = dataSource.getConnection();
PreparedStatement ps = conn.prepareStatement(sql);
ps.setString(1, shipmentId);
ResultSet rs = ps.executeQuery();
if(rs.next()) {
shipment = new Shipment(
rs.getLong("rowid"),
rs.getString("shipmentid"),
...
rs.getString("more_info_here")
);
}
ps.close();
} catch(SQLException e) {
logger.error("ShipmentDAO.getOneBy() failed: {}",
e.getMessage());
e.printStackTrace();
throw e;
} finally {
if(conn != null) {
try {
conn.close();
} catch (SQLException se) { }
}
}
return shipment;
}
Я обратился к AWS, и они толькоесть два экземпляра в их базе знаний, где сообщается об этой ошибке, и только «проблема с кодом пользователя» является разрешением.
Я не вижу каких-либо явных проблем с безопасностью потоков, но он действует так, потому что код работает безупречно, когда запускается только один поток, и каждая партия обрабатывается последовательно.
Кто-нибудьувидеть явную проблему или нужна дополнительная информация?Любая помощь приветствуется.
