spring-boot - 检查响应对象是否没有返回数据

Question

我有一个端点，用于检查数据库中是否存在标识符并返回状态。将调用此端点的 USSD API。当我使用不存在的标识符 (EcNumber) 发出请求时，响应会按我的预期返回消息。但是，当我传递数据库中的标识符时，我也会得到相同的状态message.I 需要帮助来使用 isEmpty()/null 来实现相同的目的:

ClientEndpoint.java

 @Endpoint
public class ClientEndpoint {
    private static final String NAMESPACE_URI = "http://www.onewallet.org/webservices/disburse";
    @Autowired
    private IClientService clientService;   

@PayloadRoot(namespace = NAMESPACE_URI, localPart = "getClientByEcNumRequest")
    @ResponsePayload
    public GetClienttByEcNumResponse getClient(@RequestPayload GetClientByEcNumRequest request) {
        GetClienttByEcNumResponse response = new GetClienttByEcNumResponse();

    ServiceStatus serviceStatus = new ServiceStatus();
    ClientInfo clientInfo = new ClientInfo();
    if ( clientInfo==null || clientInfo.getEcNumber()==null ){
        serviceStatus.setMessage("EC# not registered with MCP");
} else {
        BeanUtils.copyProperties(clientService.getClientByEcNumber(request.getEcNumber() ), clientInfo);
        serviceStatus.setMessage("Welcome to MCP MobileLoans");
}
    response.setServiceStatus(serviceStatus);
    return response;

当我传递以下有效 EcNumber 请求时:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:dis="http://www.onewallet.org/webservices/disburse">
   <soapenv:Header/>
   <soapenv:Body>
      <dis:getClientByEcNumRequest>
         <dis:ecNumber>5501900T</dis:ecNumber>
      </dis:getClientByEcNumRequest>
   </soapenv:Body>
</soapenv:Envelope>

我收到回复:

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
   <SOAP-ENV:Header/>
   <SOAP-ENV:Body>
      <ns2:getClienttByEcNumResponse xmlns:ns2="http://www.onewallet.org/webservices/disburse">
         <ns2:serviceStatus>
            <ns2:message>EC# not registered with MCP</ns2:message>
         </ns2:serviceStatus>
      </ns2:getClienttByEcNumResponse>

明白了。我传递了错误的对象进行检查。应该使用 entity 实例而不是 complexType 实例(来自架构定义):

@PayloadRoot(namespace = NAMESPACE_URI, localPart = "getClientByEcNumRequest")
    @ResponsePayload
    public GetClienttByEcNumResponse getClient(@RequestPayload GetClientByEcNumRequest request) {
        GetClienttByEcNumResponse response = new GetClienttByEcNumResponse();

    ServiceStatus serviceStatus = new ServiceStatus();
    **Client client=clientService.getClientByEcNumber(request.getEcNumber));**
    ClientInfo clientInfo = new ClientInfo();
    if ( client=null){
        serviceStatus.setMessage("EC# not registered with MCP");
} else {
        BeanUtils.copyProperties(clientService.getClientByEcNumber(request.getEcNumber() ), clientInfo);
        serviceStatus.setMessage("Welcome to MCP MobileLoans");
}
    response.setServiceStatus(serviceStatus);
    response.setClientInfo(clientInfo)
    return response;
