hibernate - POSTMAN @GET Couldn't get any response and Swagger @GET 请求已终止

问题描述

@GET http://localhost:8080/batchConfig/findConfigs

我的控制器

@RestController
@RequestMapping(path = "/batchConfig")
public class BatchJobConfigController {
    @Autowired
    private BatchJobConfigRepository repository;

    /*
     * Mapping url exmaple:http://localhost:8080/batchConfig/findConfigs
     */

    @GetMapping(value = "/findConfigs", consumes = MediaType.ALL_VALUE)
    List<BatchJobConfig> findAll() {
        return repository.findAll();
    }

    /*
     * http://localhost:8080/batchConfig/findConfigs?configId=1
     */
    @GetMapping(value = "/findConfigs/{configId}", consumes = MediaType.ALL_VALUE)
    BatchJobConfig findOneBatchJobConfig(@PathVariable Long id) {
        return repository.findById(id).orElseThrow(() -> new BatchJobConfigNotFoundException(id));
    }
}

主班

@SpringBootApplication
public class StartBatchJobConfigurationApplication {

    Date date = new Date();

    // start everything
    public static void main(String[] args) {
        SpringApplication.run(StartBatchJobConfigurationApplication.class, args);
    }

    // run this only on profile 'demo', avoid run this in test
    @Profile("demo")
    @Bean
    CommandLineRunner initDatabase(BatchJobConfigRepository configRepository,
            BatchJobConfigDetailsRepository detailsRepository) {

        return args -> {
            configRepository.save(new BatchJobConfig(1L, "JAVA"));
            configRepository.save(new BatchJobConfig(2L, "CC"));
        }
    }
}

模型

@Entity
@Table(name = "BATCH_JOB_CONFIG")
public class BatchJobConfig2 {
    // @OneToMany(mappedBy = "BATCH_JOB_CONFIG")
    // private Set<BatchJobConfigDetails> batchJobConfigDetails;
    @Id
    private long batchJobConfigId;
    private String addUserCd;

    public BatchJobConfig2(long batchJobConfigId, String addUserCd) {
        super();
        this.batchJobConfigId = batchJobConfigId;
        this.addUserCd = addUserCd;
    }

    public long getBatchJobConfigId() {
        return batchJobConfigId;
    }

    public void setBatchJobConfigId(long batchJobConfigId) {
        this.batchJobConfigId = batchJobConfigId;
    }

    public String getAddUserCd() {
        return addUserCd;
    }

    public void setAddUserCd(String addUserCd) {
        this.addUserCd = addUserCd;
    }

}

存储库

@Repository
public interface BatchJobConfigRepository extends JpaRepository<BatchJobConfig, Long> {

}

错误的可能原因：

网络错误：主机无法访问 证书问题：指定了 https，但服务使用的是自签名、过期或其他有问题的证书 CORS 错误：请求的服务不允许来自其他域的请求。请尝试在 chrome 中添加 Swagger Inspector Extension，因为它可以解决此问题。Swagger Inspector Extension 可能被禁用。请尝试通过以下方式启用它：chrome://extensions。

解决方案

我通过关闭所有打开的命令行窗口而不是终止我用于此应用程序的端口来解决此问题。
