弹簧集成Java DSL错误

Question

我已经设置了一个新的Spring Boot Spring Integration Spring Integration Java DSL Project使用最新的可用版本。该项目构建还可以，但是，当我运行应用程序时，我将获得：

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

所使用的依赖项当前如下：

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版本的错误组合引起的吗？我不确定如何调试此错误。

Answer 1

已经使用弹簧集成5.0时，您不需要额外的spring-integration-java-dsl依赖项。自从5.0版本以来，它已合并到核心项目。

请参阅"迁移指南"中的更多信息，并在该页面上进行春季集成Java DSL项目。
