Question

我正在使用spring framework 3.2.8

迁移我的项目，该项目基于spring integration 1.0.x构建到2.2.6

我添加了新的JAR spring-integration-core-2.2.6.RELEASE.jar并删除了旧的，并且还更新了我的applicationContext.xml文件中的xsd。下面是applicationContext.xml

中添加的xml架构详细信息

<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">

现在我面临以下案件的一些困难：

下面是一个在SI 1.0.x中运行良好的小部分：

<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" />

现在我希望用SI 2.2.6做同样的事情。在浏览完SI文档之后，我已经用以下内容更新了上面的部分：

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

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

但遗憾的是它不起作用，我也无法在SI 2.2.6中配置相似的行为。我得到以下例外：

请帮我解决这个问题。

Answer 1

根本不要使用XSD版本。迁移到新版本会更容易。
请删除未使用的xmlnses。
<thread-pool-task-executor>应替换为<task:executor>
<poller>元素必须包含<interval-trigger/>或<cron-trigger/>子元素。

这是来自Spring Integration＆lt; = 2.0的消息，而不是2.2 =＆gt;。所以，请确保使用正确的Spring Integration罐。

所有其他配置都没问题。

Answer 2

这是一个很大的跳跃（1.0.x到2.2.x）。

这些子元素在2.0中已弃用，在2.1中已删除。

请查看迁移指南2.0->2.1和2.1->2.2。 3.0.2是当前版本;它的migration guide is here。

Spring Integration从1.0.x迁移到2.2.6
