问题描述
我在Spring Boot项目中很难设置LiquiBase.我尝试浏览文档并找到一些指南-但它们似乎彼此矛盾:(
I'm having a hard time setting up LiquiBase in my Spring Boot project. I tried looking through the docs and finding some guides - but they seem contradict each other :(
我希望通过Gradle使用LiquiBase,并且希望它从Hibernate生成变更日志,并最终获得一个SQL脚本,我可以在服务器上运行该脚本以将架构更新为适当的版本.
I wish to use LiquiBase via Gradle and I want it to generate the changelogs from Hibernate and end up with a SQL script I can run on the server to update the schema to the appropriate version.
要使其通过Gradle运行,我正在使用此插件 https://github.com/liquibase/liquibase-gradle-plugin ,使用其自述文件中显示的推荐设置.
To get it to run via Gradle I'm using this plugin https://github.com/liquibase/liquibase-gradle-plugin using the recommended setup shown in their README.
要使用Hibernate差异,我正在使用 https://github.com/liquibase/liquibase-休眠
To get the Hibernate diff to work I'm using 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
}

}
}
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')
}
通过以下方式运行
但是失败了
似乎找不到Spring Boot.因此,我随后尝试删除了 liquibaseRuntime
,但随后LiquiBase Gradle插件抱怨说缺少 liquibaseRuntime
.
It looks like it cannot find Spring Boot. So I then tried removing the liquibaseRuntime
but then the LiquiBase Gradle plugin complains that liquibaseRuntime
is missing.
似乎我陷入了循环.进行此设置的理智的方法是什么?我真的不想重复 liquibaseRuntime
内的每个依赖项.此外,该文档的字面意思是:
Seems I'm stuck in a loop. What is a sane way of setting this up?I really don't want to repeat every dependency inside the liquibaseRuntime
. Also the doc literally says:
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'
}
注意
是的.为什么...
请帮助!
还...我注意到您必须编写两次数据库配置.在spring boot config中已经设置了为什么需要它?
Also... I noticed that you have to write database config twice. Why is that needed when it's already set in spring boot config?
进度
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.但这仍然行不通.
Makes the errors go away. But it still doesn't work.
运行此命令
给我这个输出

针对空数据库运行时.是的-它不起作用:(
When running against an empty database. So yeah - it doesn't work :(
推荐答案
原来,我需要添加一些未记录的魔术酱.
Turns out I needed to add some undocumented magic sauce.
diff.dependsOn compileJava
diffChangeLog.dependsOn compileJava
generateChangelog.dependsOn compileJava
dependencies {
// as before
liquibaseRuntime sourceSets.main.output // replaces liquibaseRuntime files('src/main')
}
