Spring集成Java DSL错误

Question

我已经使用最新的可用版本建立了一个新的Spring Boot Spring Integration Spring Integration Java DSL项目。项目构建正常，但当我运行应用程序时，我得到：

Caused by: java.lang.NoSuchMethodError: org.springframework.integration.dsl.StandardIntegrationFlow.isRegisterComponents()Z
    at org.springframework.integration.dsl.config.IntegrationFlowBeanPostProcessor.processStandardIntegrationFlow(IntegrationFlowBeanPostProcessor.java:139) ~[spring-integration-java-dsl-1.2.3.RELEASE.jar:?]
    at org.springframework.integration.dsl.config.IntegrationFlowBeanPostProcessor.postProcessBeforeInitialization(IntegrationFlowBeanPostProcessor.java:100) ~[spring-integration-java-dsl-1.2.3.RELEASE.jar:?]

    at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.doCreateBean(AbstractAutowireCapableBeanFactory.java:583) ~[spring-beans-5.0.3.RELEASE.jar:5.0.3.RELEASE]

当前使用的依赖项如下：

compile ("org.springframework.boot:spring-boot-starter:2.0.0.RC1") {
    exclude group: "org.springframework.boot", module: "spring-boot-starter-logging"
}
compile "org.springframework.boot:spring-boot-starter-data-jpa:2.0.0.RC1"
compile "org.springframework.boot:spring-boot-starter-log4j2:2.0.0.RC1"
compile "org.springframework.integration:spring-integration-core:5.0.1.RELEASE"
compile "org.springframework.integration:spring-integration-http:5.0.1.RELEASE"
compile "org.springframework.integration:spring-integration-jms:5.0.1.RELEASE"
compile "org.springframework.integration:spring-integration-java-dsl:1.2.3.RELEASE"

错误可能是由于jar版本的错误组合吗？我不确定如何调试此错误。

当您已经使用Spring集成5.0时，您不需要额外的Spring集成java dsl依赖关系。自5.0版以来，它已合并到核心项目中。
