MySQL5.7插入中文数据，报错：Incorrect string value: ‘\xB8\xDF\xAE\xF9\x80 at row 1

1. 首先检查数据库的字符编码,因为默认下载的MySQL数据库的字符集为latin1

show create database <数据库名>
mysql> show create database information_company;
+---------------------+------------------------------------------------------------------------------+
| Database            | Create Database                                                              |
+---------------------+------------------------------------------------------------------------------+
| information_company | CREATE DATABASE `information_company` /*!40100 DEFAULT CHARACTER SET latin1 */ |
+---------------------+------------------------------------------------------------------------------+
1 row in set (0.00 sec)

2. 修改数据库的编码格式

alter database <数据库名> character set utf8;
mysql> alter database information_company character set utf8;
Query OK, 1 row affected (0.00 sec)

3. 然后不保护以外的话插入数据应该还会报错…
4. 这个时候我们就需要修改my.ini文件
5. 本人下载的是MySQL5.7my.ini文件默认是在C:\ProgramData\MySQL\MySQL Server 5.7

• 打开“my.ini”。（修改之前尽量备份）。找到[client]在下面添加
  default-character-set=utf8mb4

# The following options will be read by MySQL client applications.
# Note that only client applications shipped by MySQL are guaranteed
# to read this section. If you want your own MySQL client program to
# honor these values, you need to specify it as an option during the
# MySQL client library initialization.
#
[client]
default-character-set=utf8mb4

• 在找到[mysqld]在下面添加
  character-set-server=utf8mb4

# SERVER SECTION
# ----------------------------------------------------------------------
#
# The following options will be read by the MySQL Server. Make sure that
# you have installed the server correctly (see above) so it reads this 
# file.
#
# server_type=3
[mysqld]
character-set-server=utf8mb4
# collation-server=utf8_general_ci

• 然后拷贝一份到我们MySQL的安装目录（默认安装在C:\Program Files\MySQL\MySQL Server 5.7）

在键盘上敲入mysql,找到mysql服务,点击重新启动
