Spring Integration DSL - 如何创建XPath Splitter？

Question

如何使用Spring Integration DSL创建XPath Splitter？什么是DSL的等价物：

<!-- Split the order into items creating a new message for each item node -->
<int-xml:xpath-splitter id="orderItemSplitter"
                   input-channel="orderChannel"
                   output-channel="orderItemsChannel">
    <int-xml:xpath-expression expression="/order/items"/>
</int-xml:xpath-splitter>

Spring Integration Java DSL没有任何<xpath-splitter>特定组件，因为它足以通过常规Java配置轻松配置：

@Bean
public AbstractMessageSplitter xpathSplitter() {
    return new XPathMessageSplitter("/order/items"); 
}

...

@Bean
public IntegrationFlow xpathFlow() {
return IntegrationFlows.from("inputChannel")
            .split(xpathSplitter())
            .get();
}
