Camel REST DSL 提供编写充当 JAX-RS 用户的 Camel 路由的能力。以下 RouteBuilder 类演示了这一点。

@Startup
@ApplicationScoped
@ContextName("rest-camel-context")
public class RestConsumerRouteBuilder extends RouteBuilder {
  @Override
  public void configure() throws Exception {

    // Use the camel-undertow component to provide REST integration
    restConfiguration().component("undertow")
      .contextPath("/rest").port(8080).bindingMode(RestBindingMode.json);

    rest("/customer")
      // GET /rest/customer
      .get()
        .produces(MediaType.APPLICATION_JSON)
        .to("direct:getCustomers")
      // GET /rest/customer/1
      .get("/{id}")
        .produces(MediaType.APPLICATION_JSON)
        .to("direct:getCustomer")
      // POST /rest/customer
      .post()
        .type(Customer.class)
        .to("direct:createCustomer");
      // PUT /rest/customer
      .put()
        .type(Customer.class)
        .to("direct:updateCustomer");
      // DELETE /rest/customer/1
      .delete("/{id}")
        .to("direct:deleteCustomer");
  }
}

通过设置绑定模式，Camel 可以通过指定 'produces （）' 或 'type （）' 配置步骤来对 JSON 数据进行 marshal 和 unmarshal JSON 数据。
