Liquibase 无法启动，因为在“迁移文件：类路径”中找不到更改日志

当我启动应用程序时，它失败并显示以下消息，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.

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

Hee 是类路径application.yaml

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，我相信您的配置有错误：

change-log: classpath:db/changelog/dbchangelog.xml

它应该是：change-log: classpath:db.changelog/dbchangelog.xml
