无法启动路由[A]，因为不允许同一终结点有多个使用者:[E]

Question

使用属性Camel.springboot.xml-rests=classpath:folder Camel/folder rest/*.xml 中定义的xml路径，通过"xml rest"将rest定义加载到Camel Spring Boot 3.2时出现此错误

我的rest定义文件如下

<?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

在找到此问题CAMEL-14969的根本原因后，我研究了一种找到简单解决方法的方法，并提出了在rest端点上指定路由ID的解决方案，方法是用route标记将其包围，如下所示。

<?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>
