Liquibase 库因 Micronaut 2.0 中的 Nullpointer 而失败

Question

我有一个带有 micronaut-data (postgresql) 和 liquibase 的 Micronaut 2.0 应用程序。 当我在 IDEA 或本地 jar 中运行应用程序时，它工作正常。应用程序有几个迁移，当它在 docker 中运行时，只有第一个成功执行，然后它失败并出现错误：

app第二次运行报错： relation marker_type already exists

如果将 Micronaut 降级到 v1 并且不更改其他代码，则应用在 docker 中运行没有问题。

Micronaut 2 出了什么问题？

更新：

application.yml的片段：

datasources:
  default:
    url: 'jdbc:postgresql://${DB_HOST:localhost}:5432/demo'
    username: 'postgres'
    password: '1234'
    driverClassName: 'org.postgresql.Driver'
jpa:
  default:
    entity-scan:
      packages: 'models'
    properties:
      hibernate:
        hbm2ddl:
          auto: none
        show_sql: true
liquibase:
  datasources:
    default:
      change-log: 'classpath:db/migrations/change-log.yml'

DB_HOST 是 docker-compose 中的环境。

更新： docker-compose.yml

version: "3.7"
services:
  app:
    build:
      context: .
      args:
        JAR_FILE: build/libs/mdemo*-all.jar
    ports:
      - "8090:8090"
    depends_on:
      - db
    environment:
      SERVER_PORT: 8090
      DB_HOST: db
  db:
    image: postgres:12
    expose:
      - "5432"
    environment:
      POSTGRES_USER: postgres
      POSTGRES_PASSWORD: 1234
      POSTGRES_DB: demo

Answer 1

我猜你遇到了以下问题。

https://liquibase.jira.com/browse/CORE-3468

解决方法是

shadowJar {
    manifest {
        attributes 'Bundle-Version': 'UNKNOWN'
        attributes 'Build-Time': 'UNKNOWN'
    }
}

Micronaut 仍在使用 3.8.0 版的 liquibase https://github.com/micronaut-projects/micronaut-liquibase/blob/master/gradle.properties#L8

库升级完成后，您将不再使用它https://github.com/micronaut-projects/micronaut-liquibase/issues/74，但它将与 Micronaut 2.1 版一起发布。

Answer 2

你能在你的资源文件夹中分享你的 application.properties 或 application.yaml 吗？

我认为您的数据源未配置，可能是通用数据源或flyway中的数据源。

我可以想象您在该配置中依赖 env var，但您没有在容器启动时提供这些。
