java - 无法解析 org.apache.camel.impl.HeaderFilterStrategyComponent 类型

Question

我在 Camel 应用程序中遇到以下问题:

The project was not built since its build path is incomplete. Cannot find the class file for org.apache.camel.impl.HeaderFilterStrategyComponent. Fix the build path then try building this project camel

public class SendMessageToActiveMq {
   public static void main(String[] args) throws Exception { 
    ConnectionFactory factory = new ActiveMQConnectionFactory();
    CamelContext context = new DefaultCamelContext();
    context.addComponent("jms", JmsComponent.jmsComponentAutoAcknowledge(factory));
    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  }
}

这是我的 Maven pom 依赖项:

   <dependency>
        <groupId>org.apache.camel</groupId>
        <artifactId>camel-core</artifactId>
        <version>3.0.0</version>
    </dependency>
    <dependency>
        <groupId>org.apache.activemq</groupId>
        <artifactId>activemq-camel</artifactId>
        <version>5.15.11</version>
    </dependency>

注意: 它确实适用于camel-core 2.24.2。为什么它不能与 3.0.0 一起使用？有什么替代方案吗？

根据 Camel 3 migration guide 。 activemq-camel 组件已移至 Apache Camel 代码库。更新您的依赖项，例如:

<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-activemq</artifactId>
    <version>3.0.0</version>
</dependency>
