java – Liquibase Hibernate插件不起作用

分类：Java作者：编程之家
如此处所述( https://github.com/liquibase/liquibase-hibernate/issues/74)我遇到了使liquibase-hibernate扩展正常工作的问题.我想我已经完成了所有设置,但似乎我一直遇到奇怪的问题.我觉得我错过了一些简单的东西,但我想我已按照提供的所有说明进行操作.

我正在使用liquibase 3.3.2,Hibernate 4.3.0.Final,java 1.7.0_71和liquibase-hibernate4-3.5.jar.我的CLAsspATH环境变量是空的,但liquibase shell脚本会添加一些东西.当我使用正常的liquibase命令进行交互时,我从$LIQUIBASE_HOME / lib /目录中删除了没有扩展名的扩展名,它可以正常工作.我用DEBUG输出重新启动命令以提供更多信息.

$echo $CLAsspATH


$java -version
java version "1.7.0_71"
Java(TM) SE Runtime Environment (build 1.7.0_71-b14)
Java HotSpot(TM) 64-Bit Server VM (build 24.71-b01,mixed mode)

$liquibase --version
Liquibase Version: 3.3.2

我的liquibase.properties文件

driver=com.MysqL.jdbc.Driver
classpath=mysql-connector-java-5.1.6.jar
url=jdbc:MysqL://localhost:3306/dirtylibs

#referenceDriver=liquibase.ext.hibernate.database.connection.HibernateDriver
referenceUrl=hibernate:spring:com.companyname.dirtylibs.persistence.entities?dialect=org.hibernate.dialect.MysqL5Dialect

如果我取消注释我的referenceDriver,我会得到这个.这里有什么我想念的吗？我以为我拥有所有必需的依赖项,而且我不确定这是否是早期问题的一些表现,其中扩展无法正确加载内容.

将hibernate jar添加到liquibase / lib文件夹后(这确实是错误的),错误变成了这个.我尝试恢复到旧版本的插件(同时降级liquibase),但它没有帮助.

解决方法

我通过将这些罐子添加到我的类路径中来实现它.这非常混乱,没有很好的记录.
我经历的过程是：

>下载这里找到的正确插件项目的源代码(https://github.com/liquibase/liquibase-hibernate/releases),在我的情况下,它是liquibase-hibernate4-3.5.
>运行mvn依赖：copy-dependencies.这会将它们转储到/ target / dependency /中.复制所有这些jar并将它们放入LIQUIBASE_HOME / lib目录中.
>我正在使用gradle,所以我使用自定义任务来复制所有依赖项.如果你正在使用maven,你可以使用自己项目中2的相同步骤来获取所有的depdenencies.我将这些库从输出目录复制到LIQUIBASE_HOME / lib目录中.

task copyToLib(type: copy) {
    into "$buildDir/output/libs"
    from configurations.runtime
}

>我还将正确的hibernate-liquibase-4.3.5.jar放入LIQUIBASE_HOME / lib目录中.

这给了我插件所需的所有依赖项.

这是一个令人讨厌的混乱球,但你能做什么:(
