Spring Boot 和 Liquibase：启动服务器时未执行迁移

Question

我使用 Liquibase 和 MongoDB 运行迁移的微服务在服务器启动时不会执行迁移，正如 Spring Boot 所声称的那样。

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter</artifactId>
    </dependency>
    <dependency>
        <groupId>org.liquibase</groupId>
        <artifactId>liquibase-core</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-mongodb</artifactId>
    </dependency>
    <dependency>
        <groupId>org.liquibase.ext</groupId>
        <artifactId>liquibase-mongodb</artifactId>
        <version>4.1.1</version>
    </dependency>
</dependencies>

spring:
  application:
    name: photo-app-liquibase
  datasource:
    driver-class-name: liquibase.ext.mongodb.database.MongoClientDriver
    url: mongodb://localhost:27017/photo-app
  liquibase:
    change-log: classpath:db/changelog/db.changelog-master.xml

迁移和主文件位于src/main/resources/db/changelog文件夹中

<?xml version="1.0" encoding="UTF-8"?>
<databaseChangeLog
    xmlns="http://www.liquibase.org/xml/ns/dbchangelog"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.liquibase.org/xml/ns/dbchangelog
    http://www.liquibase.org/xml/ns/dbchangelog/dbchangelog-3.8.xsd">

    <!-- Tried without "db/changelog" and appending "./" before already -->
    <include file="db/changelog/20201029215628_create-users-table.xml"/>
</databaseChangeLog>

但是在启动服务器时，没有运行迁移的迹象，数据库中也没有任何变化。

Liquibase 不支持 MongoDB，但它们提供了一个扩展来支持 MongoDB： => How to use Liquibase-MongoDb-Spring-boot
