【问题描述】：

遵循this 文档：

To automatically run Liquibase database migrations on startup, add the org.liquibase:liquibase-core to your classpath.

The master change log is by default read from db/changelog/db.changelog-master.yaml but can be set using liquibase.change-log. In addition to YAML, Liquibase also supports JSON, XML, and SQL change log formats.

我将我的应用程序配置为使用 liquibase 迁移。 我添加了liquibase.change-log 属性，所以我的整个application.properties 文件看起来像这样：

spring.jpa.hibernate.ddl-auto=none

spring.datasource.url=jdbc:mysql://192.168.0.1/db_name
spring.datasource.username=db_username
spring.datasource.password=super_secret_secret!123
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver

spring.datasource.testOnBorrow=true
spring.datasource.timeBetweenEvictionRunsMillis = 60000
spring.datasource.validationQuery=SELECT 1

liquibase.change-log=db.changelog-master.xml

这是我的pom.xml 和liquibase-core

但不幸的是，启动时没有任何反应。我相信这会将我的db.changelog-master.xml 中指定的表添加到我的数据库中，但SHOW TABLES 会打印一个空集。

<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

    <include file="classpath:liquibase/changelogs/init.xml"
             relativeToChangelogFile="false"/>

    <changeSet id="1" author="bob">
        <createTable tableName="department">
            <column name="id" type="int">
                <constraints primaryKey="true" nullable="false"/>
            </column>
            <column name="name" type="varchar(50)">
                <constraints nullable="false"/>
            </column>
            <column name="active" type="boolean" defaultValueBoolean="true"/>
        </createTable>
    </changeSet>

</databaseChangeLog>

【参考方案1】：

我相信你不见了

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-jdbc</artifactId>
</dependency>

在你的依赖中

【讨论】：

是的，就是这样。非常感谢。是否有任何资源可用于跟踪需要哪些 spring-boot-starter-* 依赖项，因为文档中没有任何需要它们的参考。

您可以在 spring-boot-samples github 存储库中的示例中查看 pom。您也可以接受正确的答案，以便人们看到它已解决。 ;)

是的，如果我记得下次引导应用程序时应该注意那些难以捉摸的spring-boot-starters，那么在 githb 上检查样本似乎是最好的解决方案。由于 *** 需要延迟，我无法接受您的回答。

如果你使用Spring Boot 2，那么除了添加这个依赖之外，你还需要将属性名改为spring.liquibase.change-log
