Spring Integration从1.0.x迁移到2.2.6

Question

I am migrating my project which was build on spring integration 1.0.x to 2.2.6 with spring framework 3.2.8

I have added the new JAR spring-integration-core-2.2.6.RELEASE.jar and removed the old one and also updated the xsd in my applicationContext.xml file. Below is the xml schema details added in the applicationContext.xml

<beans:beans xmlns="http://www.springframework.org/schema/integration"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns:p="http://www.springframework.org/schema/p"
    xmlns:beans="http://www.springframework.org/schema/beans"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:stream="http://www.springframework.org/schema/integration/stream"
    xmlns:jms="http://www.springframework.org/schema/integration/jms"
    xmlns:httpinvoker="http://www.springframework.org/schema/integration/httpinvoker"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
            http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
            http://www.springframework.org/schema/context
            http://www.springframework.org/schema/context/spring-context-3.2.xsd
            http://www.springframework.org/schema/integration
            http://www.springframework.org/schema/integration/spring-integration-2.2.xsd">

Now I am facing some difficulties for the below case:

Below is a small section which was working fine in SI 1.0.x :

<channel id="msg.incoming">
        <queue capacity="600" />
</channel>

<service-activator input-channel="msg.incoming" ref="consumer"
        method="doPolling">
        <poller task-executor="consumerpool">
            <interval-trigger interval="1" time-unit="SECONDS" />
        </poller>
</service-activator>

<thread-pool-task-executor id="consumerpool"
        core-size="5" max-size="30" keep-alive-seconds="1000" queue-capacity="20" />

Now I want the same thing to be done with SI 2.2.6, After going through the SI docs, I have updated the above section with the below one:

<channel id="dnd.incoming">
        <queue capacity="600" />
    </channel>

<service-activator input-channel="dnd.incoming" ref="consumer" method="doDNDScrubbing">
        <poller fixed-delay="1000" />
</service-activator>

But unfortunately it is not working and also I am not able configure like behavior in SI 2.2.6. ​I am getting below exceptions:

BeanDefinitionParsingException: Configuration problem: A <poller> element must include either an <interval-trigger/> or <cron-trigger/> child element.

Please help me resolving this.

Answer 1

1. Don't use versions for XSD at all. It will be easier to migrate to the new version.

2. Remove, please, unused xmlnses.

3. <thread-pool-task-executor> should be replaced with <task:executor>

4. A <poller> element must include either an <interval-trigger/> or <cron-trigger/> child element.

It is a message from Spring Integration <= 2.0, not 2.2 =>. So, be sure that you use correct jars of Spring Integration.

All other configuration is OK.

Answer 2

That is a big jump (1.0.x to 2.2.x).

Those child elements were deprecated in 2.0 and removed in 2.1.

Please review the migration guides 2.0->2.1 and 2.1->2.2 . 3.0.2 is the current release; its migration guide is here .
