Spring Integration Java DSL Error

I have set up a new Spring Boot + Spring Integration + Spring Integration Java DSL project using latest available versions. The project builds okay but, when I run the application, I am getting:

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:?]

The dependencies being used are currently as follows:

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"

Could the error be due to wrong combination of jar versions? I am not sure how to debug this error.

Solution

  • When you use Spring Integration 5.0 already, you don't need that extra spring-integration-java-dsl dependency. It has been merged to the core project since the version 5.0.

    See more info in the Migration Guide and on that page for Spring Integration Java DSL project.
