使用 cdi 容器独立启动骆驼答案

【问题标题】：starting camel standalone with cdi container使用 cdi 容器独立启动骆驼
【发布时间】：2016-12-15 11:41:53
【问题描述】：

我尝试了不同的方法来使用 cdi.main 创建一个独立的骆驼

org.apache.camel.cdi.Main.main();

//not org.apache.camel.Main

我还配置了 deltaspike，我看到了 cdi 容器，但是我的 CamelContext 没有启动。

如果有人已经独立运行了 Camel boot cdi，您可以发送代码吗？

更新：我不断收到这种错误：

    org.apache.webbeans.exception.WebBeansDeploymentException: javax.enterprise.inject.AmbiguousResolutionException: There is more than one Bean with type org.apache.camel.CamelContextQualifiers: [@javax.enterprise.inject.Default()]

【问题讨论】：

查看现有的 CDI 示例
我确实查看了文档以及 github 存储库，但无法使其作为独立应用程序运行。我尝试使用 apache open webbeans 对其进行配置，但使用 ApplicationScope 的 camelContext 从未启动。我的配置肯定有问题，如果有人对配置也有问题，我会回来发布配置
另一件事是指可以从此处找到的示例：camel.apache.org/camel-boot.html 或 github 存储库中的某个位置。（我只找到了一个没有cdi的独立应用）

【解决方案1】：

只是如果有人遇到同样的问题，我只是发现了问题，只是pom.xml中的配置问题。混合camel core和camel cdi版本

这是我的工作配置 => Camel、OpenWebBeans 容器和 deltaspike

*/ 启动应用程序的代码

 org.apache.camel.cdi.Main maincdi = new org.apache.camel.cdi.Main(){};
 maincdi.run();

*/骆驼上下文生产者

  public class CamelContextFactory {
      @Produces
      @ApplicationScoped
      CamelContext customize() {
          DefaultCamelContext context = new DefaultCamelContext();
          context.setName("my-custom-camel-context");
          return context;
      }

      void cleanUp(@Disposes CamelContext context) {
          // ...
      }
  }

*/创建一个上下文初始化器

    @ApplicationScoped
    public class ContextInitializer {
        @Inject
        private CamelContext ctx;

        @Inject
        @Any
        private Instance<RouteBuilder> routes;


        @PostConstruct
        public void init() {

            // add routes
            for (RouteBuilder route : routes) {
                try {
                    ctx.addRoutes(route);

                } catch (Exception ex) {
                    Logger.getLogger(ContextInitializer.class.getName()).log(Level.SEVERE, null, ex);
                }
            }
            //this.ctx.start();
        }

        @PreDestroy
        public void stop() {
            //this.ctx.stop();
        }
    }

*/ 将被注入到'routes'属性中的路由类

  public class SomeRouteClass  extends RouteBuilder {

      @Override
      public void configure() throws Exception {
          from("timer:foo?period=2000")
                  //.bean(testBean)
                  .process(new Processor() {
                      public void process(Exchange exchange) throws Exception {
                          System.out.println("route called from context  " + exchange.getContext().getName());
                      }
                  });
      }

  }
