【问题描述】:
当我启动我的应用程序时,它会失败并显示此消息,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

它适用于我。告诉我:你是如何尝试运行这个应用程序的?使用 Intellij IDEA 运行不是最好的方法,只有 CLI 命令。
