错误提示中的字符0xF0 0x9F 0x98 0x84 ，这对应UTF-8编码格式中的4字节编码（UTF-8编码规范）。
这是因为emoji的文本信息, 超时了utf-8字符集的存储范围。因为mysql中的utf-8并不是真正意义上的utf-8，它只能存储1~3个字节长度的utf-8编码，如果想存储4个字节的必须用utf8mb4类型。不而要使用utf8mb4类型，首先要保证Mysql版本要不低于 MySQL 5.5.3。
1、修改字符集编码，然后重启
[root@elastic ~]# vi /etc/my.cnf
[root@elastic ~]# cat /etc/my.cnf
[mysqld]
character-set-server=utf8mb4
collation-server = utf8mb4_unicode_ci
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
# Settings user and group are ignored when systemd is used.
# If you need to run mysqld under a different user or group,
# customize your systemd unit file for mariadb according to the
# instructions in http://fedoraproject.org/wiki/Systemd
[mysqld_safe]
log-error=/var/log/mariadb/mariadb.log
pid-file=/var/run/mariadb/mariadb.pid
#
# include all files from the config directory
#
!includedir /etc/my.cnf.d
[client]
default-character-set=utf8mb4
[mysql]
default-character-set=utf8mb42、修改字段编码为 utf8mb4
create table files(
fileId bigint auto_increment primary key,
fileName varchar(1000) not null,
fileSize bigint default 0,
fileDir varchar(100),
category varchar(100),
content text CHARACTER SET utf8mb4,
md5 varchar(64),
status tinyint default 0
)ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;解决办法2
通过程序删除特殊的4字节字符，前提是这些字符不影响原文理解。
/**
* 将emoji表情替换成*
*
* @param source
* @return 过滤后的字符串
*/
public static String filterEmoji(String source) {
if(!StringUtils.isEmpty(source)){
return source.replaceAll("[\\ud800\\udc00-\\udbff\\udfff\\ud800-\\udfff]", "*");
}else{
return source;
}
