spring - 消耗SOAP Web服务错误(未注册编码(marshal)处理程序。请检查WebServiceTemplate的配置)

Question

我遵循了入门-使用SOAP Web服务(https://spring.io/guides/gs/consuming-web-service/)来使用特定的Web服务，并且一切正常:

我做了配置类:

@Configuration
public class PMConfiguration {
    @Bean
    public Jaxb2Marshaller marshaller() {
        Jaxb2Marshaller marshaller = new Jaxb2Marshaller();
        // this package must match the package in the <generatePackage> specified in
        // pom.xml
        marshaller.setContextPath("com.inteligenciaweb.wsdl");
        return marshaller;
    }

    @Bean
    public ProcuraPMPorREClient procuraPMPorREClient(Jaxb2Marshaller marshaller) {
        ProcuraPMPorREClient client = new ProcuraPMPorREClient();
        client.setDefaultUri("http://tempuri.org/procuraPMPorRE");
        client.setMarshaller(marshaller);
        client.setUnmarshaller(marshaller);
        return client;
    } 

}

客户:

public class ProcuraPMPorREClient extends WebServiceGatewaySupport {

    private static final Logger log = LoggerFactory.getLogger(ProcuraPMPorRE.class);


    public ProcuraPMPorREResponse getPMPorRE(Integer RE) {

        ProcuraPMPorRE request = new ProcuraPMPorRE();
        request.setPMRENum(RE);

        log.info("Requesting PM for " + RE);

        ProcuraPMPorREResponse response = (ProcuraPMPorREResponse) getWebServiceTemplate()
                .marshalSendAndReceive("http://webservices.externo.policiamilitar.sp.gov.br:8071/router/wsscpm/basic",
                        request,
                        new SoapActionCallback("http://tempuri.org/procuraPMPorRE"));

        return response;
    }

}

在类里面的应用程序:

@SpringBootApplication
public class InteligenciawebApplication {

    public static void main(String[] args) {
        SpringApplication.run(InteligenciawebApplication.class, args);
    }

    @Bean
    CommandLineRunner lookup(ProcuraPMPorREClient pm) {
        return args -> {
            Integer re = 123456;        
            ProcuraPMPorREResponse response = pm.getPMPorRE(re); 
            System.err.println(response.getProcuraPMPorREResult().getNomeBancoPM());
        };
    }
}

启动应用程序时，weservice调用工作正常，因此可以在控制台上查看结果。我尝试使用相同的逻辑在其他类中调用此Web服务，但无法正常工作。例如，我已经在Controller Class上进行了测试:

@RequestMapping(value = "/soap", method = RequestMethod.GET)
public String testeSoap() {
    ProcuraPMPorREClient pm = new ProcuraPMPorREClient();
    ProcuraPMPorREResponse response = pm.getPMPorRE(123456); 
    System.out.println(response.getProcuraPMPorREResult().getNomePM());
  return null;
}

在这种情况下，Web服务将无法运行，并且系统会显示以下错误消息:java.lang.IllegalStateException:没有注册编码。检查WebServiceTemplate的配置。我不知道为什么，但是Web服务只能在特定的地方工作，而不能在其他地方工作。如果有人知道发生了什么，我将不胜感激!谢谢!

在这种情况下，我无法像我一样在Controller中实例化一个新对象:

ProcuraPMPorREClient pm = new ProcuraPMPorREClient();

取而代之的是，我需要创建一个@Autowired对象，如下所示:

@Autowired ProcuraPMPorREClient pm;

之后，我只调用相同的例程:

ProcuraPMPorREResponse response = pm.getPMPorRE(123456); 
System.out.println(response.getProcuraPMPorREResult().getNomePM());

这很好。
