## 一，改数据库编码
|
||
以下两种方案任选一
|
||
ps: 修改数据库配置可以一劳永逸，直接sql修改当机器重启时新加的设置会被还原
|
||
|
||
### 1.修改数据库配置文件
|
||
windows下的为my.ini(linux下的为my.cnf)
|
||
windows下的my.ini路径：C:\ProgramData\MySQL\MySQL Server 5.6
|
||
|
||
```bash
|
||
[client]
|
||
default-character-set = utf8mb4
|
||
|
||
[mysql]
|
||
default-character-set = utf8mb4
|
||
|
||
[mysqld]
|
||
character-set-server = utf8mb4
|
||
collation-server = utf8mb4_unicode_ci
|
||
```
|
||
|
||
## 2.修改数据库、表、字段的编码为utf8m64
|
||
|
||
```sql
|
||
-- 修改数据库:
|
||
ALTER DATABASE `dblog` CHARACTER SET = utf8mb4 COLLATE = utf8mb4_unicode_ci;
|
||
-- 修改表:
|
||
ALTER TABLE `biz_article` CONVERT TO CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;
|
||
-- 修改表字段:
|
||
ALTER TABLE `biz_article` CHANGE `content` content LONGTEXT CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci COMMENT '文章内容';
|
||
ALTER TABLE `biz_article` CHANGE `content_md` content_md LONGTEXT CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci COMMENT 'markdown版的文章内容';
|
||
```
|
||
|
||
### 二、添加配置
|
||
```
|
||
spring:
|
||
datasource:
|
||
druid:
|
||
connection-init-sqls: set names utf8mb4
|
||
``` |
