JAVA-Spring Integration Router的性能瓶颈

Question

im woring in a system with Spring integration and i need to activate differents services depending on the messages recived from an MQ Queue, i'm routing this messages based on its content, for that purpose im using an Spring Integration recipient-list-router with selector-expression .

Testing the performance of this config, im getting a bottleneck on this router.

<int:recipient-list-router id="Router" input-channel="inputChannel" default-output-channel="tslOutputChannel"> 
    <int:recipient channel="xmlOutputChannel" 
        selector-expression="payload.startsWith('&lt;?xml')" />
</int:recipient-list-router>

After routing the messages, i'm using a Spring Integration Filter and transformer, then the messages are sent to a service activator.

What can i do to improve the router's performance? and would be better to do this routing, filtering and service call with a JAVA class?

Thanks.

SpEL不太可能成为这里的巨大瓶颈，但是您可以编写Java路由器，也可以尝试配置SpEL编译器来编译表达式 。
