解决方式
1.修改数据库编码为utf8mb4

ALTER DATABASE database_name CHARACTER SET = utf8mb4 COLLATE = utf8mb4_unicode_ci;

2.修改表的编码(可以修改全部都修改,也可以只修改某一个的)(一定要修改,修改完数据库编码之后表的编码其实并没有改变,还需要单独修改表的编码)

ALTER TABLE table_name CONVERT TO CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;

3.修改mysql驱动版本
驱动版本最好在5.2以上吧

           <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>8.0.12</version>
        </dependency>

4.springboot配置,我这边使用的是阿里的druid连接池,其他的话按需配置,重点是需要配置connection-init-sqls这一项

spring:
  datasource:
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://127.0.0.1:3306/DB_NAME?useUnicode=true&autoReconnect=true&characterEncoding=utf8&serverTimezone=UTC
    username: root
    password: ***
    type: com.alibaba.druid.pool.DruidDataSource
    druid:
      connection-init-sqls: SET NAMES utf8mb4 COLLATE utf8mb4_unicode_ci
