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);
