升级 Spring 集成版本后出现 Class 转换异常

Question

我有一个 Spring 集成应用程序，它从 AS400 DB 中轮询数据，然后在进行一些修改后将其传输到 MQ。
运行很好，直到我决定升级 Spring 集成版本。
从版本 spring-integration-core-2.2.3.RELEASE 升级到 spring-integration-core-3.0.1.RELEASE.

后出现以下错误

Caused by: org.springframework.beans.factory.BeanDefinitionStoreException: Unexpected exception parsing XML document from class path resource [tcm-hosttrade-inbound-adapter.xml]; nested exception is java.lang.ClassCastException: org.springframework.beans.factory.config.RuntimeBeanReference cannot be cast to org.springframework.beans.factory.config.BeanDefinition

我检查了class的代码 - org.springframework.integration.config.xml.AbstractPollingInboundChannelAdapterParser 我只是发现这3行代码与早期版本不同 -

String channelAdapterId = this.resolveId(element, adapterBuilder.getRawBeanDefinition(), parserContext);
        String sourceBeanName = channelAdapterId + ".source";
        parserContext.getRegistry().registerBeanDefinition(sourceBeanName, (BeanDefinition) source);

所以错误是因为这一行 - parserContext.getRegistry().registerBeanDefinition(sourceBeanName, (BeanDefinition) source);

我怎样才能使这段代码工作？以下是我的豆子，可以作为参考 -

  <inbound-channel-adapter id="inboundAdapter" 
            ref="readFromMessageStore"
            channel="inboundChannel" auto-startup="false" />

Answer 1

是的，3.0.1版本有问题。它在 3.0.2 版本中得到解决。您可以查看此 link 了解详细信息：https://jira.spring.io/browse/INT-3300.

页面 link 的小摘要：


Summary Class cast exception using DefaultInboundChannelAdapterParser 
Regression: Class cast exception using DefaultInboundChannelAdapterParser
Fix Version/s       3.0.2 [ 14362 ]

Affects Version/s       3.0.1 [ 14309 ]

Answer 2

升级到新版本时，一般建议使用该行的最新版本；我很好奇你为何选择 3.0.1，而该行的最新版本是 3.0.7。当前版本为4.1.5；参见 the project page for complete version information. Generally, point releases (3.0.2, 3.0.3 etc) contain just bug fixes. Also, please pay attention to the migration guides。
