SpringBoot调用Dynamics NAV 2015 SOAP服务时遇Unknown JAXB异常

我尝试用Java SpringBoot调用Dynamics NAV 2015的SOAP WebService，该服务需要用户名、密码、域名形式的凭证。编写了SoapClientService类添加SOAP头认证信息，调用服务端TestConnection方法，同时配置RestController提供/api/test-connection接口。请求该接口时返回错误：处理请求时出错：Unknown JAXB exception。无法区分该异常是来自marshalSendAndReceive方法的序列化问题，还是目标URL认证失败导致。

已完成的准备工作：

• 从resources/wsdl目录下的ControlePreparation.wsdl文件生成Java类
• 引入jaxb-api依赖
• 配置maven-jaxb2-plugin插件
• 编写WebServiceConfig配置类初始化Jaxb2Marshaller和SoapClientService实例

核心代码 #

SoapClientService类 #

@Service
public class SoapClientService extends WebServiceGatewaySupport {

    @Value("${soap.service.url}")
    private String serviceUrl;

    @Value("${nav.user}")
    private String navUser;

    @Value("${nav.password}")
    private String navPassword;

    @Value("${nav.domain}")
    private String navDomain;

    public String testConnection() {
        // Create request object
        TestConnection request = new TestConnection();

        // Add SOAP headers for authentication
        getWebServiceTemplate().setInterceptors(new ClientInterceptor[] {
                new ClientInterceptor() {
                    @Override
                    public boolean handleRequest(MessageContext messageContext)   {
                        TransportContext context = TransportContextHolder.getTransportContext();
                        WebServiceMessage message = messageContext.getRequest();
                        SoapHeader header = ((SoapMessage) message).getSoapHeader();

                        QName navUserHeader = new QName("urn:microsoft-dynamics-schemas/codeunit/ControlePreparation", "NavUser");
                        QName navPassHeader = new QName("urn:microsoft-dynamics-schemas/codeunit/ControlePreparation", "NavPass");
                        QName navDomainHeader = new QName("urn:microsoft-dynamics-schemas/codeunit/ControlePreparation", "NavDomain");

                        header.addHeaderElement(navUserHeader).setText(navUser);
                        header.addHeaderElement(navPassHeader).setText(navPassword);
                        header.addHeaderElement(navDomainHeader).setText(navDomain);

                        return true;
                    }

                    @Override
                    public boolean handleResponse(MessageContext messageContext) {
                        // Handle response if needed
                        return true;
                    }


                    @Override
                    public boolean handleFault(MessageContext messageContext)  {
                        // Handle fault if needed
                        return true;
                    }

                    @Override
                    public void afterCompletion(MessageContext messageContext, Exception ex) {
                        // Clean up resources if needed
                    }
                }

        });


    // Make SOAP call and receive response
    TestConnectionResult response = (TestConnectionResult) getWebServiceTemplate().marshalSendAndReceive(serviceUrl, request,
            new SoapActionCallback(
                    "urn:microsoft-dynamics-schemas/codeunit/ControlePreparation:TestConnection"
            ));

        // Process response
        if (response != null) {
            return response.getReturnValue();
        } else {
            return null; // Or handle null response as needed
        }
    }
}

RestController类 #

@RestController
@RequestMapping("/api")
public class SoapController {

    @Autowired
    private SoapClientService soapClientService;

    @GetMapping("/test-connection")
    public ResponseEntity<String> testConnection() {
        try {
            String response = soapClientService.testConnection();
            if (response != null) {
                return ResponseEntity.ok(response);
            } else {
                return ResponseEntity.status(HttpStatus.INTERNAL_SERVER_ERROR)
                        .body("Failed to retrieve test connection response.");
            }
        } catch (HttpClientErrorException e) {
            return ResponseEntity.status(e.getStatusCode()).body("HTTP error occurred: " + e.getMessage());
        } catch (Exception e) {
            return ResponseEntity.status(HttpStatus.INTERNAL_SERVER_ERROR)
                    .body("An error occurred while processing the request: " + e.getMessage());
        }
    }
}
