postgresql - liquibase diff 不起作用

Question

我正在尝试使用 Hibernate 和 Liquibase 通过代码优先方法制作 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'
        }
    }
}

当我从 gradle 脚本运行 liquibase diff 命令时，如下所示: .\gradlew.bat diff 我得到以下输出:

Answer 1

堆栈跟踪表明 Liquibase 无法找到数据库驱动程序 且 未指定驱动程序类，无法从 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。
