java - 已经在使用 utf8mb4 但得到 1366 : Incorrect string value: '\xF0\x9F\x98\x81\xF0\x9F...'

Question

“不正确的字符串值”问题的所有答案都指向使用 utf8mb4。但是，我仍在使用它，但仍然出现该错误。

运行

SELECT CCSA.character_set_name, collation_name FROM information_schema.`TABLES` T,
       information_schema.`COLLATION_CHARACTER_SET_APPLICABILITY` CCSA
WHERE CCSA.collation_name = T.table_collation
  AND T.table_schema = "test"
  AND T.table_name = "products";

产生

character_set_name  collation_name
utf8mb4             utf8mb4_unicode_ci

和运行

SELECT character_set_name, collation_name FROM information_schema.`COLUMNS` 
WHERE table_schema = "test"
  AND table_name = "products"
  AND column_name = "description";

产生相同的结果。然后，当我尝试更新列 description 时: 更新 test.products SET description='Esperienza molto negativa... 😁😁😁😁SCONSIGLIATISSIMO' WHERE id ='50'

我收到上述错误

1366: Incorrect string value: '\xF0\x9F\x98\x81\xF0\x9F...' for column 'description' at row 1

我已经通过 jdbc 连接 jdbc:mysql://localhost:3306/test?useUnicode=yes;characterEncoding=utf8; 和直接通过 MySQLWorkbench 尝试了此更新。我不知道还能尝试寻找什么。我错过了什么？

编辑 SHOW CREATE TABLE

的输出

CREATE TABLE `products` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `manufacturerId_fk` int(11) NOT NULL,
  `type_fk` varchar(20) COLLATE utf8mb4_unicode_ci NOT NULL DEFAULT 'TEST',
  `ownerId_fk` int(11) DEFAULT NULL,

我在文本字段中遇到了类似的问题。 (MySQL 1366错误不正确的字符串值)

我确认数据库、表、列字符集都是utf8mb4。

通过将字段类型更改为longtext 问题已解决。

希望这可以帮助某人。
