未找到[SajSoapMessage的终结点映射，SOAP WS执行期间出现异常

我是使用String开发SOAP web服务的新手。

我按照以下过程使用Spring创建了一个SoapWeb服务https://spring.io/guides/gs/producing-web-service/

错误消息：2020-04-27 20:53:31.979 WARN 4860-[nio-8080-exec-4]o.s.ws.server.EndpointNotFound:未找到[SajSoapMessage的端点映射{http://opnt.com.si/opnt/OnGSSNorBodGateway/}可行性检查]

端点类：

@端点公共类NltProcessEndpoint｛

private static final String NAMESPACE1 = "http://opnt.com.si/opnt/OnGSSNorBodGateway";
@Autowired
private NltService service;
@PayloadRoot(namespace = NAMESPACE1, localPart = "FeasibilityCheck")
@ResponsePayload
public FeasibilityCheckResponse getResponseMessage(@RequestPayload FeasibilityCheckRequest request) {
FeasibilityCheckResponse feasibilityResponse = new FeasibilityCheckResponse();
feasibilityResponse = service.checkFeasibility(request);
return feasibilityResponse;
}           

}

如果需要，我可以共享我的代码。
