【问题描述】：

我正在尝试使用 Hibernate 和 Liquibase 使用 Code-First 方法制作 Spring Boot 2.2.x 应用程序 (Java 13)。我想根据实体对象和数据库之间的差异生成迁移。

操作系统 - Win 10 和 Mint 18 构建系统 - gradle 6.0。 数据库 - Postgres SQL。

我安装了 liquibase 实用程序 (3.8.2)。

我的 gradle 脚本：

    repositories 
        maven 
            url "https://plugins.gradle.org/m2/"
        
    
    dependencies 
        classpath 'net.ltgt.gradle:gradle-apt-plugin:0.18'
        classpath 'org.postgresql:postgresql:42.2.9'
        classpath 'org.liquibase:liquibase-core:3.8.2'
        classpath "org.liquibase:liquibase-gradle-plugin:2.0.2"
    


plugins 
    id 'org.springframework.boot' version '2.2.1.RELEASE'
    id 'io.spring.dependency-management' version '1.0.8.RELEASE'
    id 'org.liquibase.gradle' version '2.0.2'
    id 'java'



group = 'com.goodt.drive'
version = '0.0.1-SNAPSHOT'

sourceCompatibility = '13'
targetCompatibility = '13'


diff.dependsOn compileJava
diffChangeLog.dependsOn compileJava
generateChangelog.dependsOn compileJava

dependencies 

    liquibaseRuntime 'org.liquibase:liquibase-core:3.8.2'
    liquibaseRuntime "jakarta.xml.bind:jakarta.xml.bind-api:2.3.2"
    liquibaseRuntime 'org.springframework.boot:spring-boot:2.2.1.RELEASE'
    liquibaseRuntime 'org.liquibase:liquibase-groovy-dsl:2.0.1'
    liquibaseRuntime 'org.postgresql:postgresql:42.2.9'
    liquibaseRuntime 'org.hibernate:hibernate-core:5.4.10.Final'
    liquibaseRuntime 'ch.qos.logback:logback-core:1.2.3'
    liquibaseRuntime 'ch.qos.logback:logback-classic:1.2.3'
    liquibaseRuntime sourceSets.main.output 



def dbChangeLog = "$projectDir/src/main/resources/db/changelog/changelog.xml"
def generatedChangeLog = "$projectDir/src/main/resources/db/changelog/generated_changelog.xml"


liquibase 
    activities 
        main 
            changeLogFile dbChangeLog
            outputFile generatedChangeLog
            driver "org.postgresql.Driver"
            classpath "$projectDir/lib/postgresql-42.2.9.jar"
            url "jdbc:postgresql://localhost:5432/webportal"
            username "developer"
            password "123"
            referenceUrl "hibernate:spring:com.wissance.webportal.application.model.entities?dialect=org.hibernate.dialect.PostgreSQL94Dialect"
            //referenceDriver 'liquibase.ext.hibernate.database.connection.HibernateDriver'
        
    

当我像这样从 gradle 脚本运行 liquibase diff 命令时：.\gradlew.bat diff 我得到以下输出：

> Task :diff

【参考方案1】：

堆栈跟踪表明 Liquibase Cannot find database driver 和 Driver class was not specified and could not be determined from the url (hibernate:spring:com.wissance.webportal.application.model.entities?dialect=org.hibernate.dialect.PostgreSQL94Dialect)

这表明您应该将 liquibase-hibernate jar 添加到您的依赖项中，并取消注释 gradle 脚本中的 referenceDriver 行。

【讨论】：

谢谢，史蒂夫。但这不仅可以帮助我使 diff 正常运行，而且我会在下面发布解决方案，因为我不能在这里发布。

【参考方案2】：

我将 liquibase（在 gradle 中）更新到了 3.8.4 版 我添加了带有 liquibase-hibernate 和 spring-data-jpa 的 liquibaseRuntime 行 我已添加到 gradle 脚本的 liquibase-hibernate 和 spring-data-jpa 类路径 部分。

另外，我写了一篇关于如何使用 liquibase 的文章，你可以在这里找到它：https://m-ushakov.medium.com/code-first-with-spring-boot-hibernate-and-liquibase-48f5c9998d95

【参考方案3】：

不确定这是否与您遇到的错误有关，但 Liquibase 最近发布了一个 3.8.4 版本，该版本纠正了 Java 9+ 中的一些 Spring Boot 错误。 https://www.liquibase.org/2019/12/liquibase-3-8-4-released.html

我会尝试运行它，看看它是否可以为您解决问题。

【讨论】：

我刚刚检查了 3.8.4 liquibase 版本并得到了相同的行为。但是，如果您检查一下您的环境，我将不胜感激（也许我做错了什么）。谢谢。
