2.6. Java DSL 路由迁移示例

流程

1. 下载 Spring Boot 示例。本例演示了如何使用 Spring Boot 使用简单的 Apache Camel 应用程序。

2. 进入从上一步中提取示例文件的目录：

   $ cd <directory_name>

3. 在 src/main/java/sample/camel/ subfolder 中查找名为 MyCamelRouter.java 的文件。

4. 将 Fuse 应用程序的路由定义添加到 MyCamelRouter.java，如下例所示：

   package sample.camel;
   
   import org.apache.camel.builder.RouteBuilder;
   import org.springframework.beans.factory.annotation.Autowired;
   import org.springframework.stereotype.Component;
   
   /**
    * A simple Camel route that triggers from a timer and calls a bean and prints to system out.
    * <p/>
    * Use <tt>@Component</tt> to make Camel auto-detect this route when starting.
    */
   @Component
   public class MyCamelRouter extends RouteBuilder {
   
       // we can use spring dependency injection
       @Autowired
       MyBean myBean;
   
       @Override
       public void configure() throws Exception {
           // start from a timer
           from("timer:hello?period={{myPeriod}}").routeId("hello")
                   // and call the bean
                   .bean(myBean, "saySomething")
                   // and print it to system out via stream component
                   .to("stream:out");
       }
   
   }

5. 运行您的 CSB 应用程序。

   mvn spring-boot:run
