mvn liquibase:diff，每次生成相同的文件

Question

对持久实体所做的任何更改，只有对实体所做的更改才会反映在生成的 diff liquibase 文件中。但目前它每次运行“mvn liquibase:diff”时都会生成完整的更改日志文件。

请在 pom.xml 中找到设置

liquibase.properties 文件：

url=jdbc:postgresql://localhost:5432/db
username=***
password=***
driver=org.postgresql.Driver
changeLogFile=src/main/resources/db/changelog/db.changelog-master.xml
outputChangeLogFile=src/main/resources/db/changelog/db.changelog-master.xml
referenceUrl=hibernate:spring:com.company.project?dialect=org.hibernate.dialect.PostgreSQLDialect&hibernate.physical_naming_strategy=org.springframework.boot.orm.jpa.hibernate.SpringPhysicalNamingStrategy&hibernate.implicit_naming_strategy=org.springframework.boot.orm.jpa.hibernate.SpringImplicitNamingStrategy
referenceDefaultSchemaName=db

请告诉我这里缺少什么。

根据doc需要指定：

--referenceUsername= 基础数据库用户名。

--referencePassword= 基本数据库密码。

--referenceUrl= 基本数据库 URL。

referenceUrl - 看起来很神奇，您需要指定正确的数据库 URL。
