Jhipster中的Liquibase遷移異常

[英]Liquibase migration exception in Jhipster

 原文  2018-02-06 19:15:37  1   1    java/ apache-kafka/ jhipster/ liquibase/ spring-cloud-stream

問題描述

我有一個帶有兩個微服務和一個網關的JHipster項目。 兩者都是通過JHipster生成的。 我正在嘗試從Spring Cloud Stream with Kafka Streams的Projects Microservice中將對象發送到ChargeCodes微服務。 為此，我在ProjectResource.java文件中添加了Spring Cloud Stream代碼 。 根據我的要求，每當創建新項目對象時，Spring Cloud Stream都應將其發送給Kafka主題，第二個微服務中的Kafka使用者將使用它。 為簡單起見，我在同一項目中創建了生產者和消費者。 當我編譯微服務時，出現以下異常。 

liquibase.exception.MigrationFailedException: Migration failed for change set config/liquibase/changelog/20180205173557_added_entity_Address.xml::20180205173557-1::jhipster:

我的帶有Spring Cloud Stream和Kafka的標准Spring Boot Rest API應用程序運行正常，沒有任何問題。 我不確定JHipster代碼有什么問題。 代碼上傳到github倉庫中 。

乍看之下，似乎是由於某種原因導致DATABASECHANGELOG中的一個或多個行被刪除，因此，用於創建表projects.address的變更集的Liquibase再次被運行，但是該表已經存在。
