Java 使用springboot Web服务器使用soap服务时出现Marshall错误

鉴于Java11不再支持WebServiceSOAP，我尝试使用springboot使用soap服务。我正在尝试按照此链接“”上的教程进行操作。 然而，我没有调用本地服务，而是调用了wsdl为的邮政服务。 从这个wsdl中，maven正在生成类：BuscaEventos（将是请求类）和BuscaEventosResponse（将是响应类）。 通过上面传递的wsdl，我能够通过soapUi生成调用，并传递我在代码中使用的相同调用参数。但是，对于springboot，我在BuscaClient类的最后一个命令中遇到以下错误：

Caused by: org.springframework.oxm.MarshallingFailureException: JAXB marshalling exception; nested 
exception is javax.xml.bind.MarshalException
- with linked exception:
[com.sun.istack.SAXException2: it is not possible to do marshalling of the type 
"com.example.spring.soap.schemas.BuscaEventos" as an element because it was not found in a annotation @XmlRootElement]

有趣的是，我不能将@XmlRootElement注释放在BuscaEventos类中，即使它是由maven生成的。在本教程中，无需执行任何进一步的步骤，也无需修改生成的类

除了教程之外，我唯一要做的就是将“schemas”文件夹（maven创建类的文件夹）设置为源文件夹

这些是我的课程：

@SpringBootApplication
public class SoapApplication {

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

    @Bean
    CommandLineRunner lookup(BuscaCliente cliente) {
        return args -> {
            BuscaEventosResponse response = cliente.getBusca();
            System.out.println(response.getReturn().toString());
        };
    }
}

////////

@Configuration
public class BuscaConfig {

@Bean
public Jaxb2Marshaller marshaller() {
    Jaxb2Marshaller marshaller = new Jaxb2Marshaller();
    // this package must match the package in the <generatePackage> specified in
    // pom.xml
    marshaller.setContextPath("com.example.spring.soap.schemas");
    return marshaller;
}

@Bean
public BuscaCliente buscaCliente(Jaxb2Marshaller marshaller) {
    BuscaCliente client = new BuscaCliente();
    client.setDefaultUri("http://webservice.correios.com.br/service/rastro/Rastro");
    client.setMarshaller(marshaller);
    client.setUnmarshaller(marshaller);
    return client;

}

////这些是mavem从wsdl生成的类/////
