Apache Camel Scheduler错误：无法解析端点

Question

我正在尝试使用“调度程序组件-http://camel.apache.org/scheduler.html，但出现错误。我需要每60秒触发调度程序并调用我的bean。我从文档中提取了示例，并尝试照原样实施，但失败。

public class SchedulerRoute extends RouteBuilder {
@Override
public void configure() throws Exception {
    from("scheduler://foo?period=6000&delay=50").to("bean:logBean?method=sayHello");
}}

我收到此错误：

org.apache.camel.FailedToCreateRouteException: Failed to create route route2: Route(route2)[[From[scheduler://foo?period=6000&delay=50]] -... because of Failed to resolve endpoint: scheduler://foo?delay=50&period=6000 due to: Failed to resolve endpoint: scheduler://foo?delay=50&period=6000 due to: There are 1 parameters that couldn't be set on the endpoint. Check the uri if the parameters are spelt correctly and that they are properties of the endpoint. Unknown parameters=[{period=6000}]

我尝试了TIMER组件，它可以完美运行，但不能运行调度程序。

此代码可与计时器组件一起使用

public class SchedulerRoute extends RouteBuilder {
@Override
public void configure() throws Exception {
    from("timer://foo?fixedRate=true&period=6000").to("bean:logBean?method=sayHello");
        }}

有什么想法我在这里想念吗？

Answer 1

那是调度程序文档中的一个错误。 没有名为period选项。 您应该使用delay来设置触发频率。 我现在正在更新文档，因此下次生成该网站时正确。

http://camel.apache.org/scheduler

这也是异常消息告诉您的内容：未知参数= [{period = 6000}
