Question

我使用最新版本建立了一个新的Spring Boot + Spring Integration + Spring Integration Java DSL项目。项目构建正常但是，当我运行应用程序时，我得到了：

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]

目前使用的依赖关系如下：

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"

错误是由于jar版本的错误组合造成的吗？我不知道如何调试此错误。

Answer 1

当您已经使用Spring Integration 5.0时，您不需要额外的spring-integration-java-dsl依赖项。自版本5.0以来，它已合并到核心项目中。

在Migration Guide和Spring Integration Java DSL项目的页面上查看更多信息。
