红帽全球峰会第 122 章 XQuery
Camel 支持 XQuery 以允许一个 Expression或 Predicate 在 DSL 中使用。
例如，您可以使用 XQuery 在 Message Filter 中创建一个 predicate，或作为 Recipient List 的表达式。
122.1. 依赖项
要在 camel 路由中使用 XQuery，您需要添加实现 XQuery 语言的 camel-saxon 的依赖项。当将 xquery 与 Red Hat build of Camel Spring Boot 搭配使用时，请确保使用以下 Maven 依赖项来支持自动配置：
<dependency> <groupId>org.apache.camel.springboot</groupId> <artifactId>camel-saxon-starter</artifactId> </dependency>
<dependency>
<groupId>org.apache.camel.springboot</groupId>
<artifactId>camel-saxon-starter</artifactId>
