我正在尝试使用顶部、格式和过滤器查询参数运行 Camel Olingo2 路由到 OData 服务，但是 Olingo 组件没有对参数进行编码，因此它会引发 URISyntaxException，如果我在调用组件之前对参数进行编码，那么参数将返回无效，有什么方法可以将过滤参数与 Olingo2 组件一起使用？

例子：

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 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。
