Apache Camel + Spring boot 异常数据格式“jaxb”无法创建

Question

我是 Apache Camel 的新手。我的要求很简单

1. 程序应该读取 XML
2. 屏蔽我想要的字段
3. 生成屏蔽 XML

我有现有的应用程序做同样的事情，但它不起作用。创建新的简单 Spring Boot 项目如下。要求仅使用 Apache Camel。

com.example.demo包和sample.xml中的所有以下类都存在于资源中

public class ApacheCamelDemoApplication {

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

}

@Component
public class MyRoute extends RouteBuilder {

    @Override
    public void configure() throws Exception {
        from("file:src/main/resources?fileName=sample.xml&noop=true").unmarshal().jaxb("com.example.demo")
                .bean(new XmlMaskingBean()).marshal().jaxb("com.example.demo").to("mock:output");

    }
}

@Component
public class XmlMaskingBean {

    public void maskSensitiveData(MyXmlObject xmlObject) {
        xmlObject.setCreditCardNumber("XXXX-XXXX-XXXX-" + xmlObject.getCreditCardNumber().substring(15));
    }
}

@Component
@XmlRootElement(name = "data")
public class MyXmlObject {
    private String name;
    private String creditCardNumber;
}

我遇到以下错误

如果我添加以下依赖项

<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-jaxb</artifactId>
    <version>4.5.0</version>
</dependency>

出现以下错误
