Spring数据源hibernate enconding

Question

我尝试了我在互联网上找到的每个解决方案，但有些变音符号没有保存到mysql 5.7.17数据库中。 （一些罗马尼亚变音符号被保存，一些不被保存：ţşă - 不保存，但是â和î被保存了。）

连接网址：

jdbc:mysql://dbserver:3306/dbtest?useUnicode=true&connectionCollation=utf8mb4_general_ci&characterSetResults=utf8mb4&characterEncoding=UTF-8

Databasa Collat​​ion：utf8mb4_general_ci并尝试了utf8_general_ci 存储引擎：InnoDB

Java模型包含String属性，其设置如下：

model.setAuthor(new String(author.getBytes(), Charset.forName("UTF-8")))

数据库托管在Linux上，“locale”命令输出：

LANG=en_US.UTF-8
LANGUAGE=en_US
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=

Mysql conf：

其他弹簧属性：

spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.sqlScriptEncoding=UTF-8

有人有类似的问题，可以提出一些解决方案吗？

感谢。
