发表于 更新于

命名的优点在于易于理解，把定义的流程场景下，下面记录一下，camel 内部对 CamelContext 和 route 自动命名的实现

CamelContext 命名

内部使用 CamelContextNameStrategy 接口来实现

/**
 * Strategy for assigning name to a {@link org.apache.camel.CamelContext}.
 *
 * @see ManagementNameStrategy
 */
public interface CamelContextNameStrategy {

    /**
     * Gets the name
     * <p/>
     * The {@link #isFixedName()} determines if the name can be re-calculated such as when using a counter, or the name
     * is always fixed.
     *
     * @return the name.
     */
    String getName();

    /**
     * Gets the next calculated name, if this strategy is not using fixed names.
     * <p/>
     * The {@link #isFixedName()} determines if the name can be re-calculated such as when using a counter, or the name
     * is always fixed.
     *
     * @return the next name
     */
    String getNextName();

    /**
     * Whether the name will be fixed, or allow re-calculation such as by using an unique counter.
     *
     * @return <tt>true</tt> for fixed names, <tt>false</tt> for names which can re-calculated
     */
    boolean isFixedName();
}

Route 命名

Route 的 xml 配置由 RoutesDefinition 定义，其继承自 NamedNode，当 routeId 没有手动被设置时，会由 NodeIdFactory 自动创建一个 routeId
