我在liquibase中运行Java代码更改集。但我正面临这个问题,我得到了ClassNotFoundException。我做了一些搜索,但找不到任何有用的东西。尽管 this link 的一些研究很有用。我正在使用liquibase-core-2.0.1。
以下是我的变更集
<changeSet id="111" author="myname" >
<customChange class="com.example.CreateTableTask">
</customChange>
</changeSet>
以下是我的java类
public class CreateTableTask implements CustomTaskChange
{
private static Logger log = Logger.getLogger(CreateTableTask.class.getName());
@Override
public void execute(Database database) throws CustomChangeException
{
System.out.print("testsomestring");
try
{
JdbcConnection databaseConnection = (JdbcConnection) database.getConnection();
log.info("testsomestring");
}
catch (Exception e)
{
throw new CustomChangeException(e);
}
}
@Override
public String getConfirmationMessage()
{
return null;
}
@Override
public void setUp() throws SetupException
{
}
@Override
public void setFileOpener(ResourceAccessor resourceAccessor)
{
}
@Override
public ValidationErrors validate(Database database)
{
return null;
}
}
以下是我得到的例外

您使用什么命令启动Liquibase,包含自定义代码的jar文件在哪里?
它应该工作的方式是Liquibase将扫描所提到的类的类路径。你可以给liquibase.bat(或liquibase.sh)一个参数来指定一个类路径,或者如果我没记错的话,Liquibase会默认查看它的lib目录。
