在 Gradle Spring Boot Hibernate 项目中设置 LiquiBase

[英]Setup LiquiBase in a Gradle Spring Boot Hibernate project

我很难在我的 Spring Boot 项目中设置 LiquiBase。 我尝试浏览文档并找到一些指南 - 但它们似乎相互矛盾:(

我希望通过 Gradle 使用 LiquiBase,我希望它从 Hibernate 生成变更日志,并最终得到一个 SQL 脚本,我可以在服务器上运行以将架构更新到适当的版本。

为了让它通过 Gradle 运行,我使用这个插件https://github.com/liquibase/liquibase-gradle-plugin使用他们的自述文件中显示的推荐设置。

为了让 Hibernate diff 工作,我正在使用https://github.com/liquibase/liquibase-hibernate

这是我的build.gradle文件:

buildscript {
    ext {
        springBootVersion = '2.0.5.RELEASE'
    }
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
    }
}

plugins {
    id 'java'
    id 'net.ltgt.apt' version '0.10' // https://projectlombok.org/setup/gradle
    id 'org.liquibase.gradle' version '2.0.1' // https://github.com/liquibase/liquibase-gradle-plugin
}

apply plugin: 'eclipse-wtp'
apply plugin: 'org.springframework.boot'
apply plugin: 'io.spring.dependency-management'
apply plugin: 'war'

group = 'com.example'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = 1.8

repositories {
    mavenCentral()

    maven {
        credentials {
            username = oracleUser
            password = oraclePass
        }
        url 'https://www.oracle.com/content/secure/maven/content'
    }
}

liquibase {
  activities {
    main {
      changeLogFile 'main.groovy'
      url 'jdbc:oracle:thin:@localhost:1521:XE'
      referenceUrl 'hibernate:spring:com.example?dialect=org.hibernate.dialect.Oracle10gDialect'
      username 'user'
      password 'pass'
    }
  }
}

configurations {
    providedRuntime
}

dependencies {
    compile('org.springframework.boot:spring-boot-starter-data-jpa')
    compile('org.springframework.boot:spring-boot-starter-data-rest')
    compile('org.springframework.boot:spring-boot-starter-hateoas')
    compile('org.springframework.boot:spring-boot-starter-jooq')
    compile('org.springframework.boot:spring-boot-starter-web')
    compile('org.springframework.boot:spring-boot-starter-mail')
    compile('com.github.waffle:waffle-spring-boot-starter:1.9.0')
    compile('com.oracle.jdbc:ojdbc8:12.2.0.1')
    runtime('org.springframework.boot:spring-boot-devtools')
    compileOnly('org.projectlombok:lombok')
    apt('org.projectlombok:lombok:1.18.2')
    liquibaseRuntime('org.liquibase:liquibase-core:3.6.2')
    liquibaseRuntime('org.liquibase:liquibase-groovy-dsl:2.0.1')
    liquibaseRuntime('org.liquibase.ext:liquibase-hibernate5:3.6')
    liquibaseRuntime('com.oracle.jdbc:ojdbc8:12.2.0.1') // duplicate...
    providedRuntime('org.springframework.boot:spring-boot-starter-tomcat')
    testCompile('org.springframework.boot:spring-boot-starter-test')
    testCompile('org.springframework.restdocs:spring-restdocs-mockmvc')
}

通过运行它

> .\\gradlew diffChangeLog -PrunList=main

但失败了

任务 :diffChangeLog liquibase-plugin:运行“主要”活动...在 2018 年 9 月 26 日星期三 13:36:24 CEST 启动 Liquibase(版本 3.6.2 于 2018-07-03 11:28:09 构建)异常线程“main” java.lang.NoClassDefFoundError: org/springframework/core/io/ClassPathResource at liquibase.ext.hibernate.database.HibernateSpringPackageDatabase.isXmlFile(HibernateSpringPackageDatabase.java:54)

看起来它找不到Spring Boot。 所以我然后尝试删除liquibaseRuntime但随后 LiquiBase Gradle 插件抱怨缺少liquibaseRuntime

似乎我陷入了一个循环。 什么是设置这个的理智方法? 我真的不想在liquibaseRuntime重复每个依赖liquibaseRuntime 文档也从字面上说:

 dependencies { // All of your normal project dependencies would be here in addition to... liquibaseRuntime 'org.liquibase:liquibase-core:3.6.1' liquibaseRuntime 'org.liquibase:liquibase-groovy-dsl:2.0.1' liquibaseRuntime 'mysql:mysql-connector-java:5.1.34' }

请注意

// 除了...

是的。 为什么...

请帮忙!

另外...我注意到你必须写两次数据库配置。 当它已经在 spring boot 配置中设置时,为什么需要它?


进步

因此将liquibaseRuntime更改为

liquibaseRuntime('org.liquibase:liquibase-core:3.6.2')
liquibaseRuntime('org.liquibase:liquibase-groovy-dsl:2.0.1')
liquibaseRuntime('org.liquibase.ext:liquibase-hibernate5:3.6')
liquibaseRuntime('com.oracle.jdbc:ojdbc8:12.2.0.1')
liquibaseRuntime('org.springframework.boot:spring-boot-starter-data-jpa')
liquibaseRuntime files('src/main')

使错误消失。 但它仍然不起作用。

运行这个命令

.\\gradlew 差异

给我这个输出

针对空数据库运行时。 所以是的 - 它不起作用:(

原来我需要添加一些无证的魔法酱。

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

dependencies {
   // as before
   liquibaseRuntime sourceSets.main.output // replaces liquibaseRuntime files('src/main')
}

我知道这是一个旧线程,但我想为那些后来找到这个答案的人添加一些说明......

liquibaseRuntime配置不从任何其他配置继承。 这是因为在大多数情况下,Liquibase 只需要能够解析更改日志并连接到数据库。 要使用 Hibernate 模块之类的东西,或者从代码生成更改日志,您需要向 liquibaseRuntime 添加额外的内容,例如 Hibernate 或 Spring Data,并且您需要srcSets.main.output才能找到您的项目文件本身。

评论说“除了...之外,您的所有正常项目依赖项都将在这里......”指的是您将在块中拥有一堆其他依赖项来构建和运行您的项目,而不是它们将成为一部分liquibaseRuntime配置。 如果您确实希望项目中的所有库也成为liquibaseRuntime一部分,您可以将configurations.liquibaseRuntime.extendsFrom configurations.runtime添加到您的 build.gradle 中,或者如果您已经有一个configurations块,您可以添加liquibaseRuntime.extendsFrom runtime扩展到该块。 这应该将所有项目依赖项和项目文件本身添加到您的 liquibaseRuntime。

我希望这有帮助。

这就是我使用 Gradle 6.3.0 的方式:

configurations {
    liquibaseRuntime.extendsFrom runtimeClasspath
}
dependencies {
    liquibaseRuntime sourceSets.main.output
}
