Failed to start route [A] because of duplicate id detected: [B]

Getting this error when loading rest definitions via "xml-rests" to Camel Spring Boot 3.2 with the XML path defined in the property camel.springboot.xml-rests = classpath:folder-camel/folder-rest/*.xml

My rest definition file looks as following

<?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 id="id1" path="/test">
<get id="id2" uri="/folderuri">
<to id="id3" uri="log:test-log-rest-route" />
</get>
</rest>
</rests>

The exception stack trace is

org.apache.camel.FailedToStartRouteException: Failed to start route first-test-get-id because of duplicate id detected: first-test-to-id. Please correct ids to be unique among all your routes.

Solution

  • The issue CAMEL-14969, was caused by producer and consumer route for the rest point being named the same. A possible workaround is to introduce ROUTE tag with the separate ID so incoming rest and outgoing route are having different IDs

    <?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>
