Apache Camel spring splitter 与聚合器 xml 的并行处理不像 Java DSL 那样工作

Question

What would be equivalent xml for the below java DSL, please suggest

 public class OrderRouter1 extends RouteBuilder {

@Override
public void configure() throws Exception {

    from("direct:processOrder")
        .split(body().method("getItems"), new OrderItemStrategy())
        .parallelProcessing()
        .to("direct:processItem")
     .end();


    from("direct:processItem")
        .choice()
            .when(body().method("getType").isEqualTo("Book"))
                .to("bean:itemService?method=processBook").
            otherwise()
                .to("bean:itemService?method=processPhone");
}

}

I tried using the below xml configuration, without using aggregator, but when i am enabling parallelprocessing, it is working sequentially.

 <camelContext id="orderCtx" xmlns="http://camel.apache.org/schema/spring">
   <route>
        <from uri="direct:processOrder" />
        <split parallelProcessing="true">
        <simple>${body}</simple>
            <to uri="direct:processItem" />
        </split>

    </route>

    <route>
        <from uri="direct:processItem" />
            <bean beanType="com.apache.camel.aggregrator.ItemSvc" method="processBook"/>
            <bean beanType="com.apache.camel.aggregrator.ItemSvc" method="processPhone"/>
        </route>


</camelContext>

Answer 1

i would suggest the following change to the upper route "processOrder"

<split parallelProcessing="true">
    <simple>${body.getItems}</simple>
    <to uri="direct:processItem" />
</split>

if you want to use your AggregationStrategy again, you could add strategyRef="yourBean" to the splitter

Answer 2

Finally i was able to get the equivalent java DSL to XML and its working as expected

<bean id="orderItemStrategy" class="com.apache.camel.aggregrator.OrderItemStrategy" />
<bean id="itemService" class="com.apache.camel.aggregrator.ItemSvc" />
<camelContext id="orderCtx" xmlns="http://camel.apache.org/schema/spring">
    <route>
        <from uri="direct:processOrder" />
        <split parallelProcessing="true" strategyRef="orderItemStrategy">
            <simple>${body.getItems}</simple>
            <to uri="direct:processItem" />
        </split>
    </route>
    <route>
        <from uri="direct:processItem" />
         <choice>
        <when>
            <simple>${body.getType} == 'Book'</simple>
           <to uri="bean:itemService?method=processBook" />
        </when>
         <otherwise>
           <to uri="bean:itemService?method=processPhone" />
        </otherwise>
    </choice>
    </route>
</camelContext>
