红帽全球峰会245.11. 使用案例
以下路由从 Manufacturer 源中读取前 5 条目，通过升序名称属性读取。
from("direct:...")
.setHeader("CamelOlingo2.$top", "5");
.to("olingo2://read/Manufacturers?orderBy=Name%20asc");
from("direct:...")
.setHeader("CamelOlingo2.$top", "5");
.to("olingo2://read/Manufacturers?orderBy=Name%20asc");
以下路由使用传入 id 标头中的 key 属性值读取 Manufacturer 条目。
from("direct:...")
.setHeader("CamelOlingo2.keyPredicate", header("id"))
.to("olingo2://read/Manufacturers");
from("direct:...")
.setHeader("CamelOlingo2.keyPredicate", header("id"))
.to("olingo2://read/Manufacturers");
以下路由使用正文消息中的 java.util.Map<String, Object> 创建 Manufacturer 条目。
from("direct:...")
.to("olingo2://create/Manufacturers");
from("direct:...")
.to("olingo2://create/Manufacturers");
以下路由每 30 秒轮询 Manufacturer delta 源 。bean blah 更新 bean paramsBean ，将更新的 !deltatoken 属性添加 ODataDeltaFeed 结果中返回的值。由于初始 delta 令牌未知，消费者端点将首次生成 ODataFeed 值，并在后续轮询时 ODataDeltaFeed。
from("olingo2://read/Manufacturers?queryParams=#paramsBean&consumer.timeUnit=SECONDS&consumer.delay=30")
.to("bean:blah");
from("olingo2://read/Manufacturers?queryParams=#paramsBean&consumer.timeUnit=SECONDS&consumer.delay=30")
.to("bean:blah");
