获取异常'Cannot find any routes with this RouteBuilder reference: RouteBuilderRef[routebuilderOne]'

Question

当我尝试根据配置连接路由构建器时，我Cannot find any routes with this RouteBuilder reference: RouteBuilderRef[routebuilderOne]出现异常。

路由生成器 1 的类文件

import org.apache.camel.spring.SpringRouteBuilder;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;
@Component
public class RoutebuilderOne extends SpringRouteBuilder {
     @Value("${routebuilder.stream.one}")
     private boolean                 autoStartupRouteOne;
     @Override
     public void configure() throws Exception {
          from(source1).autoStartup(autoStartupRouteOne).split().method("splitLogic","splitMethod").to(destination1);
     }
}

路由生成器 2 的类文件

import org.apache.camel.spring.SpringRouteBuilder;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;
@Component
public class RoutebuilderTwo extends SpringRouteBuilder {
     @Value("${routebuilder.stream.two}")
     private boolean                autoStartupRouteTwo;
     @Override
     public void configure() throws Exception {
        from(source2).autoStartup(autoStartupRouteTwo).to(destination2);
     }
}

骆驼上下文文件

 </beans>

属性文件中autoStartupRouteOne,autoStartupRouteTwo

的值

 autoStartupRouteOne = false
 autoStartupRouteTwo = true

有没有其他方法可以实现基于条件的路由选择？

Answer 1

您需要

为@Component提供一个 id，而不是使用类名作为 id。Java 类名应以大写开头。

不确定弹簧注释是否可以做到这一点，但也许你可以做@Component(name = "routebuilderOne")或其他事情。

Answer 2

我遇到了同样的异常。不同的是，我的代码一直在工作，然后似乎随机停止。我们可能已经升级了骆驼版本，但我不确定。无论哪种方式，为了修复它，我只是停止了 karaf，然后使用 clean 选项运行启动脚本。之后一切都加载得很好。希望这对其他人有所帮助。
