Question

我正在尝试为Spring云流创建Spring云合约。我有源，处理器和接收器。源使用SourcePollingChannelAdapte。合同groovy文件如下所示：

package contracts.messaging

import org.springframework.cloud.contract.spec.Contract


Contract.make {
    description("""
Sends a non XhubJobState in Message

""")
    // Label by means of which the output message can be triggered
    label 'accpetable_message'
    // input to the contract
    input {
        // the contract will be triggered by a method
        triggeredBy('verifyValidXhubJobState()')
    }
    // output message of the contract
    outputMessage {
        // destination to which the output message will be sent
        sentTo 'verifications'
        // the body of the output message
        body([
                jobName:"Invalid_Destinations"              
        ])
    }
}

当尝试进行maven安装时，我得到了例外：

"Exception took place while trying to resolve the destination. Will assume the name [verifications]
java.lang.NullPointerException: null
    at org.springframework.cloud.contract.verifier.messaging.stream.StreamStubMessages.resolvedDestination(StreamStubMessages.java:89)......."

我在application.properties文件

中定义了以下的propery

"spring.cloud.stream.bindings.output.destination= verifications"

我是否遗漏了配置中的内容？

我还没有看到你的代码，但我只能猜到你的基类中你错过了这些注释 - https://github.com/spring-cloud-samples/spring-cloud-contract-samples/blob/master/producer/src/test/java/com/example/BeerMessagingBase.java#L14-L19。您的上下文没有开始，所以没有注入字段，这就是您获得NPE的原因。
