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

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:
下载此处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 dependency:copy-dependencies
。这会将它们转储到/target/dependency/
。复制所有这些罐子并将它们放入LIQUIBASE_HOME/lib
目录。
我使用gradle所以我使用自定义任务来复制所有依赖项。如果您正在使用maven,则可以在自己的项目中使用与2相同的步骤来获取所有的depdenencies。我将这些库从输出目录复制到LIQUIBASE_HOME/lib
目录。
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。
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,但你能做些什么:(
答案 1 :(得分: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
因此插件会假设这些已经由您的应用程序在类路径中提供,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:
<plugin>
<groupId>org.liquibase</groupId>
<artifactId>liquibase-maven-plugin</artifactId>
<version>3.4.1</version>
<dependencies>
<dependency>
<groupId>org.liquibase.ext</groupId>
<artifactId>liquibase-hibernate5</artifactId>
<version>3.6</version>
</dependency>
<dependency>
<groupId>org.liquibase</groupId>
<artifactId>liquibase-core</artifactId>
<version>3.5.3</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-jdbc</artifactId>
<version>4.3.2.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-beans</artifactId>
<version>4.3.2.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<version>4.3.2.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-orm</artifactId>
<version>4.3.2.RELEASE</version>
</dependency>
</dependencies>
</plugin>
如果你很热衷,你可以在github repo上做一个pull请求,从pom中删除提供的范围,哦,也可能是这行:
<role>architect</role>
答案 2 :(得分:1)
我尝试过的路径与接受的路径有点不同。我在war的pom.xml中创建了一个dev配置文件(我正在使用maven),它与默认配置文件完全相同,但包含war / WEB-INF / lib下的Liquibase-hibernate依赖jar文件。然后不使用提供的liquibase命令行,而是直接使用liquibase.jar文件,类路径是我的war文件:
java -jar $LIQUIBASE/liquibase.jar --classpath=<WAR FILE HERE> --defaultsFile=<yourpath>/liquibase.properties --logLevel=info
然后创建了一个connvenience脚本,它将使用liquibase-hibernate配置文件构建我的项目,然后执行diffChangeLog命令。
答案 3 :(得分:0)
我得到了同样的错误。我通过删除hibernate.cfg.xml中的hbm2ddl-property来修复它。如果启用此属性,则无法在cfg.xml中读取驱动程序类。在git中liquibase-hibernate wiki中有一个部分,它说“为什么不使用HBM2DDL”,但它并没有真正说明要从cfg.xml中删除它。
