那些遇到过的问题

Liquibase Hibernate插件不起作用

Jaz*_*epi 6 java hibernate liquibase liquibase-hibernate

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

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.

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:

  1. 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.

  2. 跑mvn dependency:copy-dependencies.这将它们转储成/target/dependency/.复制所有这些罐子并将它们放入您的LIQUIBASE_HOME/lib目录中.

  3. 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
}
    Run Code Online (Sandbox Code Playgroud)

  4. 我也把正确的hibernate-liquibase-4.3.5.jar放入LIQUIBASE_HOME/lib目录.

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:(

Gav*_*n S 6

如果检查此插件的源代码,则以下依赖项(所有spring依赖项)在pom中标记为"提供"范围:

spring-test
spring-jdbc
spring-beans
spring-context
spring-orm
Run Code Online (Sandbox Code Playgroud)

因此,插件将假设这些已经由您的应用程序在类路径上提供,但这不会自动发生在您的maven构建中,因为它不会使用与您的应用程序相同的类路径运行.

所以,要修复,在插件中添加依赖项,比执行jar文件shuffle更容易:
