【问题描述】：
在运行 Spring Boot JPA 示例时：https://spring.io/guides/gs/accessing-data-jpa/ 针对 MySQL 数据库并尝试存储“便便堆”表情符号????我收到异常 java.sql.SQLException: Incorrect string value: '\xF0\x9F\x92\xA9\xF0\x9F...'
我将我的数据库配置为使用 utf8mb4 编码。
我知道这不是 MySQL 的问题，因为我可以使用 MySQL 客户端创建客户并将其存储在数据库中。我什至可以运行示例应用程序并让它找到带有“一堆便便”表情符号的客户。

这是我从示例中修改的 Application.java：
@SpringBootApplication
public class Application implements CommandLineRunner {
@Autowired
CustomerRepository repository;
public static void main(String[] args) {
SpringApplication.run(Application.class);
}
@Override
public void run(String... strings) throws Exception {
// save a couple of customers
repository.save(new Customer("????????????????", "????????????????"));
// fetch all customers
System.out.println("Customers found with findAll():");
System.out.println("-------------------------------");
for (Customer customer : repository.findAll()) {
System.out.println(customer);
}
System.out.println();
// fetch an individual customer by ID
Customer customer = repository.findOne(1L);
System.out.println("Customer found with findOne(1L):");
System.out.println("--------------------------------");
System.out.println(customer);
System.out.println();
}
}
这是我用来配置我的 JDBC 连接的 application.yml 文件。我使用了许多在研究此问题时发现的技术，但似乎没有任何效果。
spring:
datasource:
url: "jdbc:mysql://localhost:3306/poo_test?useUnicode=yes&characterEncoding=utf8&characterResultSets=utf8"
username: root
password:
connectionInitSqls: "SET NAMES utf8mb4 COLLATE utf8mb4_unicode_ci;"
driverClassName: com.mysql.jdbc.Driver
testOnBorrow: true
validationQuery: SELECT 1
jpa:
show-sql: false
database-platform: org.hibernate.dialect.MySQL5Dialect
hibernate:
ddl-auto: update
naming_strategy: org.hibernate.cfg.EJB3NamingStrategy
connection:
CharSet: utf8mb4
characterEncoding: utf8
useUnicode: true
这似乎是一个常见问题，但我还没有找到解决方案。任何帮助将不胜感激。
