Java CXF RESTful:未找到请求类ContentType:application/json的消息正文读取器

我必须用CXF2.7.11实现REST服务，该服务已经实现了WS-SOAP服务

我得到一个错误“没有为请求类MyRequest，ContentType:application/json找到消息体读取器”

我正在尝试以下实现：

@Path("/myService")
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_JSON)
public class MyServiceImpl implements MyService {

    @Override
    @POST
    @Path("/myOperation")
    public MyResponse myOperation(MyRequest request){
        // my implementation
    }

但我得到了以下错误：

如何解决此问题？

此错误意味着CXF中没有注册

MessageBodyReader

因为我没有使用Spring，也没有ApplicationContext，所以我按如下方式解决了它：

private void createService(Class<?> serviceClass, String address, Object serviceImpl) {
    JAXRSServerFactoryBean srvFactory = new JAXRSServerFactoryBean();
    srvFactory.setServiceClass(serviceClass);
    srvFactory.setAddress("/rest"+address);
    srvFactory.setServiceBean(serviceImpl);
    srvFactory.getInInterceptors().add(new CustomInInterceptor());
    srvFactory.getOutInterceptors().add(new CustomOutInterceptor());
    srvFactory.setProvider(new JacksonJsonProvider());
    srvFactory.create();
}

private void createService（类serviceClass、字符串地址、对象serviceImpl）{
JAXRSServerFactoryBean srvFactory=新的JAXRSServerFactoryBean（）；
srvFactory.setServiceClass（serviceClass）；
srvFactory.setAddress（“/rest”+地址）；
setServiceBean（serviceImpl）；
srvFactory.getInInterceptors（）.add（新的CustomInInterceptor（））；
srvFactory.GetOutiterCeptors（）.add（新的CustomOutiterCeptor（））；
setProvider（新的JacksonJsonProvider（））；
srvFactory.create（）；
}

我需要注册一个提供者，为此我使用了

JacksonJsonProvider

，它就像一个符咒
