我遇到了JDBC问题.
我有以下代码:
//blargeparam is a blob column.
PreparedStatement pst =connection.prepareStatement("update gcp_processparams_log set blargeparam= ? where idprocessparamslog=1");
pst.setBinaryStream(1,inputStream);

我收到以下错误:

我的连接字符串是 jdbc:oracle:oci:@.....
Oracle版本为11g.
从错误消息似乎缺少某些东西但是:
这是我的类路径中Oracle JDBC JAR的清单:

我不是Spring或Feign方面最有经验的人,所以我想知道我在这里缺少什么。
简单的假冒客户:
@FeignClient(name = "my-other-service")
public interface OtherServiceClient {
@GetMapping(value = "/foo/{fooId}")
@ResponseBody
String getFoo(@PathVariable int fooId);
}

取决于伪装客户端的服务:
@Service
public class FooService {
private final FooRepository fooRepository;
private final BarRepository barRepository;
private OtherServiceClient otherServiceClient;
@Autowired
public OrderService(
FooRepository fooRepository,
BarRepository barRepository,
OtherServiceClient otherServiceClient) {
this.fooRepository= fooRepository;
this.barRepository = barRepository;
this.otherServiceClient = otherServiceClient;
}
