背景
参考文档 开发者指南->开发环境运行halo，在 windows 上以开发环境运行 halo。
现象
运行成功无报错，且能成功进入站点初始化。但是在填写初始化信息提交保存的时候页面提示 500 服务器错误。查看日志后发现有以下堆栈错误：

通过搜索引擎搜索可知，报错原因是因为操作系统的编码是GBK， 而文件采用UTF-8编码，两者编码不一致导致。（该问题一般window系统才会出现）
查看当前 windows 系统编码可用命令：
chcp
若输出为: 936，表示编码格式为 GBK
若输出为: 65001，表示编码格式为 UTF8
解决方案
我这里采用的是直接修改操作系统默认编码，若有其他更好的方案可在评论区补充。
修改Windows操作系统默认编码可参考文章：win10 配置系统默认utf-8编码
修改编码到 UTF-8 后，删除 ${user.home}/halo2-dev 文件，并且 ui 也重新 build 一下（因为我具体不知道是哪一部分编码不一致了，是h2数据库?ui?亦或是 jar 包？ 为了简单所以便全部清除重新build，也请了解这方面的大佬能够解解惑），然后再运行，初始化页面就正常了。
