apchecamelxmldsl-get路由定义在最新的camel3.19版本中抛出了一个错误

Question

我已经自己寻找了一段时间来解决这个问题，但最终在这里提出了问题，因为到目前为止我找不到任何解决方案。我们有一个在apachecamel上开发的带有xmldsl定义的应用程序，它在旧版本的apachecamel中运行良好。我将它更新到了最新的3.19版本，在部署应用程序时出现了以下错误。

Caused by: org.xml.sax.SAXParseException; lineNumber: 35; columnNumber: 22; cvc-complex-type.3.2.2: Attribute 'uri' is not allowed to appear in element 'get'.

<get uri="/bye" consumes="application/json">

</get>
<post uri="/bye">
<to uri="mock:update" />
</post>
</rest>
<route>
<from uri="direct:hello" />

<constant>Hello World</constant>
</transform>
</route>
<route>
<from uri="direct:bye" />
<transform>
<constant>Bye World</constant>
</transform>
</route>
</camelContext>
</beans>

路线的定义如官方文件所示。任何帮助都将不胜感激。

自Camel 3.16.0版本以来，uri属性已重命名为path，请参阅此票证中的说明https://issues.apache.org/jira/browse/CAMEL-17673?focusedCommentId=17493997&page=com.atlassian.jira.plugin.system.sissuetabanels%3comment选项卡面板#comment-17493997

在3.16.0之前的驼色版本中

自Camel v3.16.0起

参见https://camel.apache.org/schema/spring/camel-spring-3.16.0.xsd

遗憾的是，Camel文档没有更新以反映这一变化，示例仍然使用uri属性：https://camel.apache.org/manual/rest-dsl.html#_rest_dsl_with_xml_dsl
