Spring Integration DSL不推荐使用类

Question

我在这个版本中使用了spring integration和java-dsl依赖项。

• spring-integration-jdbc- 5.0.0M6
• spring-integration-ws- 5.0.0M6
• spring-integration-http- 5.0.0M6
• spring-integration-jmx- 5.0.0M6
• spring-integration-core- 5.0.0M6
• spring-integration-java-dsl- 1.2.2 RELEASE

由于新的JdbcMetadataStore，我必须使用5.0.0M6版本。

上周，我使用了spring集成4.3.11RELEASE和java-dsl-1.2.2RELEASE，我的应用程序工作正常。

升级过程后，抛出此运行时异常：

Caused by: java.lang.NoClassDefFoundError: org/springframework/integration/expression/IntegrationEvaluationContextAware

... 15 common frames omitted

IntegrationFlowBeanPostProcessor类定义有2个，我的应用程序可以使用它：org.springframework.integration.dsl.config.IntegrationFlowBeanPostProcessor

和下面的代码，它抛出类未找到异常：

if (component instanceof org.springframework.integration.expression.IntegrationEvaluationContextAware)

另一个类在这个包中：org.springframework.integration.config.dsl

它不使用IntegrationEvaluationContextAware。

但我的应用程序使用第一个。

它可能是什么原因？

谢谢

我现在阅读Spring Integration 4.3到5.0迁移指南，我看到了这一点：Java DSL Spring Integration Java DSL已经与Java 8代码库合并到Core项目中。旧项目仍然适用于以前的Spring Integration版本，并且与5.0版本不兼容。我删除java-dsl依赖项，我的项目工作。对不起我的问题
