window版 启动报错

[yunzhao824]

启动后报错“COMMON_SYSTEM_ERROR: 系统开小差啦，请尝试刷新页面或者联系管理员”，展开数据库表也报这个错，执行查询也报这个错，好像做任何操作都报这个错

多少版本？另外能够截个图，看下日志，发我一下。帮助里有打开日志。

看一下是不是配置参数少了，或者网络通吗？

[Chat2DB-Pro]

方便加钉钉或者微信，详细看一下呢？1 8 0 4 2 0 0 0 7 0 9

[Chat2DB-Pro]

可以参考： url: jdbc:mysql://127.0.0.1:3306/xx?useUnicode=true&characterEncoding=utf8&useSSL=false

增加参数useUnicode=true&characterEncoding=utf8&useSSL=false

[yunzhao824]

刚安装完成的时候没报错的，密码肯定是对的，因为刚开始的时候，能够把这个连接下的所有数据库都展示出来，从我做了一个操作后就一直报错了，就是我查了一个很大的表，没有给条件和限制数量的参数，报了内存溢出了，然后就一直报错了，所有跟数据库的交互操作都会报错

[yunzhao824]

可以参考： url: jdbc:mysql://127.0.0.1:3306/xx?useUnicode=true&characterEncoding=utf8&useSSL=false

增加参数useUnicode=true&characterEncoding=utf8&useSSL=false

不用加这个，卸载重装后不报错了，请参考我上面关于问题出现的操作过程的描述，你们应该是能够找到一些优化的点的。

[Chat2DB-Pro]

明白了，知道原因了，我再去优化下。
