我想将liquibase引入我的项目，首先我想根据我的hibernate实体生成一个changelog文件。

到目前为止，我有：

application.properties

# HIBERNATE
# Write out schema into sql script
spring.jpa.properties.javax.persistence.schema-generation.scripts.create-target=target/schema-h2.sql
spring.jpa.properties.javax.persistence.schema-generation.scripts.action=create
spring.jpa.hibernate.ddl-auto=validate
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.H2Dialect

# DATABASE
spring.datasource.platform=h2
spring.datasource.driver-class-name=org.h2.Driver
spring.datasource.url=jdbc:h2:mem:testdb
spring.datasource.username=sa
spring.datasource.password=
spring.h2.console.enabled=true

# LIQUIBASE
spring.liquibase.enabled=true
spring.liquibase.url=jdbc:h2:mem:testdb
spring.liquibase.user=sa
spring.liquibase.password=
spring.liquibase.changeLog=classpath:/db/h2/liquibase-changelog-master.xml

当尝试使用生成变更日志文件时，mvn liquibase:generateChangeLog我得到如下信息：

// A big list of artifacts ...

如您所见，它显示为No changes found, nothing to do，但是我希望我的第一个变更日志包含初始表的创建。

我也看到了，似乎它试图从空数据库而不是从hibernate类创建一个changelog文件：

Generating Change Log from database SA @ jdbc:h2:mem:testdb (Default Schema: PUBLIC)

输出文件myaddon.db.changelog.xml如下所示：

<?xml version="1.1" encoding="UTF-8" standalone="no"?>
<databaseChangeLog
    xmlns="http://www.liquibase.org/xml/ns/dbchangelog"
    xmlns:ext="http://www.liquibase.org/xml/ns/dbchangelog-ext"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.liquibase.org/xml/ns/dbchangelog-ext http://www.liquibase.org/xml/ns/dbchangelog/dbchangelog-ext.xsd http://www.liquibase.org/xml/ns/dbchangelog http://www.liquibase.org/xml/ns/dbchangelog/dbchangelog-3.6.xsd" />

感谢您的帮助。
