用java飞行迁移 [英] Flyway Migration with java

问题描述

我学习了flywaydb迁移，java使用JDBC连接，并且还通过SpringTemplate支持spring，但是flyway不能与DAO一起使用。

I learnt flywaydb migration with java works with JDBC connection and also spring support through SpringTemplate, but flyway doesn't work with DAOs.

用于更多的表/实体关系，它使用DAO而不是sql进行迁移变得更容易。

for tables/entities with more relationships,it makes life much easier to do migration with DAO's rather than sql.

是否有解决方案或解决方法来解决这个问题？

is there a solution or work-around to deal with this ?

推荐答案

首先，Flyway有自己的交易管理系统，不使用Spring交易处理。

First, Flyway has its own transaction managing system and does not use Spring transaction handling.

如果您的DAO扩展 JdbcDaoSupport ，您可以手动实例化您的DAO，然后在DAO中手动注入提供的 JdbcTemplate ：

If your DAOs extend JdbcDaoSupport, you could instantiate manually the your DAO and then manually inject the provided JdbcTemplate in the DAO:

public class MyJdbcMigration implements SpringJdbcMigration {
  public void migrate(JdbcTemplate jdbcTemplate) {
    MyJdbcDao dao = new MyJdbcDao();
    dao.setJdbcTemplate(jdbcTemplate);
    dao.updateDate();
  }
}
