spring-boot - Liquibase 无法启动，因为在“迁移文件 : class path”中找不到更改日志

Question

当我启动我的应用程序时，它失败并显示此消息，指出更改日志文件的类路径不存在:

Description:

Liquibase failed to start because no changelog could be found at 'Migration File: class path resource [db/changelog/dbchangelog.xml] cannot be resolved to URL because it does not exist'.

Action:

Make sure a Liquibase changelog is present at the configured path.

看起来我在 application.yaml 中有正确的类路径，所以我不知道为什么它说它不存在。

Hee 是 application.yaml 中的类路径

spring:
  datasource:
    url: jdbc:mysql://localhost:3306/db_product
    username: user
    password: password
    driver-class-name: com.mysql.cj.jdbc.Driver
  jpa:
    hibernate.ddl-auto: none
    database-platform: org.hibernate.dialect.MySQLDialect
    show-sql: true
  liquibase:
    change-log: classpath:db/changelog/dbchangelog.xml
    enabled: true

根据您发布的文件树，我认为您的配置有误:

更改日志:classpath:db/changelog/dbchangelog.xml

应该是:更改日志:类路径:db.changelog/dbchangelog.xml
