5.3. JAXB


JAXB 支持通过 Camel JAXB 数据格式 提供。

Camel 支持 unmarshalling XML 数据到 JAXB 注解的类,以及从类到 XML 的 marshalling。以下演示了一个简单的 Camel 路由,用于处理 Camel JAXB 数据格式类的 marshalling 和 unmarshalling。

5.3.1. JAXB Annotated 类

@XmlRootElement(name = "customer")
@XmlAccessorType(XmlAccessType.FIELD)
public class Customer implements Serializable {

    private String firstName;
    private String lastName;

    public Customer() {
    }

    public Customer(String firstName, String lastName) {
        this.firstName = firstName;
        this.lastName = lastName;
    }

    public String getFirstName() {
        return firstName;
    }

    public void setFirstName(String firstName) {
        this.firstName = firstName;
    }

    public String getLastName() {
        return lastName;
    }

    public void setLastName(String lastName) {
        this.lastName = lastName;
    }
}

5.3.2. JAXB 类 XML 表示

<customer xmlns="http://org/wildfly/test/jaxb/model/Customer">
    <firstName>John</firstName>
    <lastName>Doe</lastName>
</customer>

5.3.3. Camel JAXB Unmarshalling

WildFlyCamelContext camelctx = contextFactory.createCamelContext(getClass().getClassLoader());

final JaxbDataFormat jaxb = new JaxbDataFormat();
jaxb.setContextPath("org.wildfly.camel.test.jaxb.model");

camelctx.addRoutes(new RouteBuilder() {
    @Override
    public void configure() throws Exception {
        from("direct:start")
        .unmarshal(jaxb);
    }
});
camelctx.start();

ProducerTemplate producer = camelctx.createProducerTemplate();

// Send an XML representation of the customer to the direct:start endpoint
Customer customer = producer.requestBody("direct:start", readCustomerXml(), Customer.class);
Assert.assertEquals("John", customer.getFirstName());
Assert.assertEquals("Doe", customer.getLastName());

5.3.4. Camel JAXB Marshalling

WildFlyCamelContext camelctx = contextFactory.createCamelContext();

final JaxbDataFormat jaxb = new JaxbDataFormat();
jaxb.setContextPath("org.wildfly.camel.test.jaxb.model");

camelctx.addRoutes(new RouteBuilder() {
    @Override
    public void configure() throws Exception {
        from("direct:start")
        .marshal(jaxb);
    }
});
camelctx.start();

ProducerTemplate producer = camelctx.createProducerTemplate();
Customer customer = new Customer("John", "Doe");
String customerXML = producer.requestBody("direct:start", customer, String.class);
Assert.assertEquals(readCustomerXml(), customerXML);
