作为 Camel 2.18 版提供
ribbon 组件提供对客户端侧负载平衡的 Netflix Ribbon 使用。
Maven 用户需要将以下依赖项添加到其 pom.xml 中：
<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-ribbon</artifactId>
<version>x.x.x</version>
<!-- use the same version as your Camel core version -->
</dependency>当使用 ServiceCall EIP 时，这个组件有助于在客户端中应用负载平衡功能。
