无法启动路由 [A]，因为不允许多个消费者使用同一端点：[E]

Question

通过 "xml-rests" 将剩余定义加载到 Camel Spring Boot 3.2 时出现此错误，其中 XML 路径在属性 camel.springboot.xml-rest 中定义= 类路径:folder-camel/folder-rest/*.xml

我的其余定义文件如下所示

<?xml version="1.0" encoding="UTF-8"?>
<rests xmlns="http://camel.apache.org/schema/spring" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="
       http://camel.apache.org/schema/spring https://camel.apache.org/schema/spring/camel-spring-3.2.0.xsd
       ">
<rest path="/test">
<get uri="/folderuri">
<to uri="log:test-log-rest" />
</get>
</rest>
</rests>

异常堆栈跟踪是

找到这个问题的根本原因后 CAMEL-14969，我研究了一种方法来找到一个简单的解决方法，并提出了通过用 ROUTE 标记包围它来在其余端点上指定路由 ID 的解决方案如下。

<?xml version="1.0" encoding="UTF-8"?>
<rests xmlns= . . . >
<rest id="id1" path="/test">
  <get id="id2" uri="/folderuri">
    <route id="id4">
      <to id="id3" uri="log:test-log-rest-route" />
    </route>
  </get>
</rest>
</rests>

无法启动路由 [A]，因为不允许多个消费者使用同一端点：[E]
