Camel Olingo2解析URI？

Question

我正在尝试使用top，format和filter queryParams运行Camel Olingo2路由到OData服务，但Olingo组件不编码params，因此它抛出URISyntaxException，如果我在调用之前编码params组件然后param将返回为无效，有没有办法使用Olingo2组件的过滤器参数？

示例：

路线示例

from("timer://camelpoll?period=120000")
    .id("PersonPoll")
    .log("CAMEL_POLLING_IN_PROGRESS")
    .setHeader("CamelOlingo2.$top", constant("5"))
    .setHeader("CamelOlingo2.$format", constant("json"))
    .setHeader("CamelOlingo2.$filter", constant("Timestamp gt datetime'2014-06-26T03:30:00.000'"))
    .to("olingo2://read/Persons");

错误日志

好吧，看起来像olingo2组件有问题所以我必须创建一个自定义组件来实现这一点。
