Quarkus 1.5.2.Final:Quarkus resteasy自动JAXB编组/解编不'；行不通

我有一个Quarkus micro服务，它公开了一个REST接口，其端点如下所示：

...
@POST
@Consumes(value = MediaType.APPLICATION_XML)
public Response createMoneyTransferOrder(MoneyTransfer moneyTransfer);
...

@Singleton
@Named("moneyTransferBean")
public class MoneyTransferBean
{
  @Inject
  @RestClient
  private MoneyTransferResource moneyTransferResource;
  ...
  public void sendMoney(MoneyTransfer moneyTransfer)
  {
    moneyTransferResource.createMoneyTransferOrder(moneyTransfer);
  }
  ...
}

MoneyTransfer是一个JAXB对象：

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "MoneyTransfer",propOrder = {"sourceAccount", "targetAccount", "amount"})
public class MoneyTransfer 
{
  ...
}

使用有效的MoneyTransfer对象调用上述端点时，会引发以下异常：

2020-07-26 12:41:26,306 ERROR [org.apa.cam.pro.err.DefaultErrorHandler] (Camel (camel-1) thread #0 - file://src/main/resources/inbox)

似乎发生的情况是，quarkus resteasy无法按照thge JAX-RS规范的要求将MoneyTransfer对象封送/解封到XML，并且需要一个定制的转换器。然而，JAX-RS规范（quarkus resteasy是其实现）明确要求自动编组/解编以@XmlType注释的类，就像我的例子一样

有人知道这里可能有什么问题吗？我想提及的是，这种自动编组/解编自JBoss/Wildfly/Thorntail上的RESTeasy以来一直有效。最后但并非最不重要的一点是，REST服务调用是由Camel 3.3.0（quarkus Camel REST）进行的，如果这个细节有任何区别的话。代码如下：

...
restConfiguration().host("localhost:8081/api")
  .producerComponent("http").bindingMode(RestBindingMode.xml);
...
.to("http://localhost:8081/api?consumes=application/xml");

我在回答我自己的问题。最后，由于某种原因，Camel“rest”端点似乎不支持从/到Java到/从XML的自动编组/解编。因此，我需要更换以下路线：

...
restConfiguration().host("localhost:8081/api").producerComponent("http").bindingMode(RestBindingMode.xml);
...
.to("rest://post:api")

作者：

其中，moneyTransferBean如下所示：

...
@POST
@Consumes(value = MediaType.APPLICATION_XML)
public Response createMoneyTransferOrder(MoneyTransfer moneyTransfer);
...

@Singleton
@Named("moneyTransferBean")
public class MoneyTransferBean
{
  @Inject
  @RestClient
  private MoneyTransferResource moneyTransferResource;
  ...
  public void sendMoney(MoneyTransfer moneyTransfer)
  {
    moneyTransferResource.createMoneyTransferOrder(moneyTransfer);
  }
  ...
}

这样，它就如预期的那样工作了。然而，我非常失望，因为我无法使用驼峰端点，不得不求助于这种黑客：-(

您确定错误是由RestEasy引发的吗？似乎Camel正在引发此错误。您是否也添加了Camel jaxb依赖项？当然，我有Camel quarkus jaxb。当Camel尝试执行端点到（“rest://...骆驼“休息”组件应该只调用javax.ws.rs.client，它应该执行所需的自动转换。那么，与resteasy相反，quarkus resteasy是否可能不支持javax.ws.rs.client？
