Question

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

我的 rest 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

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，并提出了解决方案，通过在 rest 端点上指定路由 ID，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>
