Question

我遇到一个问题，就是在有负载的情况下运行了大约一天后，Spring Boot服务突然无法创建连接。

我使用了标准的Spring Boot 2项目启动器。创建了一个休息控制器，一个模型，一个服务和一个存储库。

<Page.DataContext>
        <vm:Pg7FirmwareUpdateViewModel/>   <= Here
    </Page.DataContext>

    <Page.Resources>
        <!-- Sets Progress Bar View -->
        <DataTemplate DataType="{x:Type svm:ErrorViewModel}">   <= Here
            <sv:ErrorView/>
        </DataTemplate>
    </Page.Resources>

回购

@Entity
@Table(name = "partners")
public class Partner {

    /** Unique identifier. */
    @Id
    @JsonProperty("id")
    private long id;

    /** Partner name. */
    @JsonProperty("name")
    private String name;

    /**
     * Default constructor. Not usable publicly.
     */
    protected Partner() {
    }

    // etc...
}

服务

/**
 * Partner repo.
 */
public interface PartnerRepository extends CrudRepository<Partner, Long> {
}

控制器

@Service
public class PartnersService {

    /** Access to Partner repo. */
    @Autowired
    private PartnerRepository partnerRepo;

    /**
     * Get partner data.
     *
     * @param id Partner identifier.
     * @return Partner instance, or null if not found.
     */
    public Partner getPartner(final long id) throws ServiceException {
        if (id <= 0) {
            throw new ServiceException("Please enter a valid partner identifier.");
        }
        final Optional<Partner> partner = partnerRepo.findById(id);
        return partner.orElse(null);
    }
}

一切都是默认配置。在生产中使用了一段时间后，我得到：

@RestController
public class PartnerController extends BaseController {

    /** Partners service. */
    @Autowired
    private PartnersService partnersService;

    @RequestMapping(value = "/partners/api/v1/partners/{id}", method = GET)
    public ResponseEntity<FilldResponse> getPartner(@PathVariable final long id) {
        final FilldResponse response = new FilldResponse();
        HttpStatus httpStatus = HttpStatus.OK;
        try {
            final Partner partner = partnersService.getPartner(id);
            if (partner != null) {
                response.setData(partner);
                response.setMessage("Partner retrieved successfully.");
            } else {
                response.setMessage("Partner not found.");
                response.setStatusCode(4000);
                response.setStatus(false);
                httpStatus = HttpStatus.NOT_FOUND;
            }
        } catch (Exception ex) {
            response.setStatus(false);
            response.setMessage(ex.getMessage());
            response.setStatusCode(4000);
            httpStatus = HttpStatus.BAD_REQUEST;
        }
        return new ResponseEntity<>(response, httpStatus);
    }
}

它在AWS中作为docker映像运行。

是否存在可能导致此问题的未配置的已知问题或配置？
