java - 按上下文名称运行 Liquibase 变更集

Question

有什么方法可以使用 Liquibase API 仅运行一组变更集吗？

以下代码在启动集成测试类之前初始化整个架构:

liquibase = new Liquibase(
    LIQUIBASE_CHANGELOG_PATH,
    new FileSystemResourceAccessor(),
    new JdbcConnection(embeddedTestDatabase.getConnection())
);
liquibase.dropAll();
liquibase.update(""); // PROBLEM: for some reason this launch all changesets including changesets with name `test`

现在我想在特定的测试方法之前执行类似 DBUnit 的 @DatabaseSetup 的操作 - 意味着仅使用 test 上下文执行变更集:

liquibase.update("test"); // PROBLEM : this also run all changesets

<changeSet author="me" id="some_id" logicalFilePath="some_path" context="test">
    <sql>
        INSERT INTO COMPANY (ID, CREATED_AT, CREATED_BY, NAME) VALUES (1, '2017-09-15 16:55:57.558', 'My company');
    </sql>
    <rollback>
        DELETE FROM COMPANY;
    </rollback>
</changeSet>

Answer 1

是的，the "contexts" feature in Liquibase在这里做你需要的事情。

文档中给出的示例符合您的要求。

文档解释:

When you run the migrator though any of the available methods, you can pass in a set of contexts to run. Only changeSets marked with the passed contexts will be run.

If you don’t assign a context to a changeSet, it will run all the time, regardless of what contexts you pass in to the migrator.

因此，如果您不希望它们在此处运行，我认为您需要向其余迁移添加除“测试”之外的上下文。也许是“main”？
