flyway 非常坑爹的中文乱码问题

flyway 也真是够了，动不动乱码，烦死了！

我的命令是这样的：

flyway -driver=com.mysql.jdbc.Driver -user=root -password=123456 -url=jdbc:mysql://192.168.11.200:3316/test2 -outOfOrder=true -locations=filesystem:E:/dev/lk_sql migrate

表的行的内容出现了问号， column 的注释也是全是问号。

Windows上执行，出现了乱码，真特么奇了怪了。但是同事机器上执行同样的sql 就不会有乱码。

难道是系统编码的问题？查看了下 cfcp 是一样的，都是 gbk

flyway.conf 配置不对？ flyway.encoding 默认是关闭了的，而且上面写了默认是 UTF-8，我不需要改吧，手动改为 UTF-8，一样的，还是不行。难道 flyway 的bug ？

为什么同事那边就可以了呢？

把他的 flyway-5.1.4 安装包拿过来（也就是 flyway-commandline-5.1.4-windows-x64.zip），重新搞一遍，发现也ok了！

真是搞不懂。我的 flyway-5.1.4 好像也是 flyway-commandline-5.1.4-windows-x64.zip 解压得来的，为什么就是不行呢？难道 build 版本不同？记不得了。。

算了，先这样吧。我本地不行。尝试 Jenkins 执行运行 shell 的 flyway 命令不行。后面实在郁闷了，于是直接shell 执行 flyway migrate，发现 linux 直接执行也不行啊。。为什么？

重新下载一个 flyway-5.2.4，也不行。我擦，一直都是乱码，真是郁闷。

真是没办法，执行 flyway ，发现可以设置编码，通过： -configFileEncoding=utf8 -encoding=UTF-8。两个都试过了，都不行啊！难道需要 jdbc url 指定编码？通过 ?useUnicode=true&characterEncoding=utf8 发现根本就执行不了。。

flyway -configFileEncoding=utf8  -driver=com.mysql.jdbc.Driver -user=root -password=123456  -url=jdbc:mysql://192.168.11.12:3306/test2?useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&allowMultiQueries=true  -outOfOrder=true -locations=filesystem:E:/dev/lk_sql   migrate

UTF-8 编码改成 UTF8 ， GBK, 都于事无补。真的郁闷。

后面把flyway-commandline-5.1.4-windows-x64.zip 上传到别的 linux 机器，执行flyway migrate。发现好了，没有乱码了！这个，难道跟 linux 的环境有关？

对比了 linux 系统语言，发现是一样的啊。。

真是没办法，这个编码问题真是难缠啊！！网上搜索一把，搞来搞去，仍然解决不了任何问题啊！

执行 flyway ，发现可以通过-X 调试。对比了两个linux 机器上相同 flyway migrate 的debug 信息，发现了细微区别！
