无法获得JDBC连接；嵌套的异常是java.sql.SQLException：null

Question

从本地计算机上的数据库服务器获取以下响应，

{
    "timestamp": "2020-03-22T13:18:30.383+0000",
    "status": 500,
    "error": "Internal Server Error",
    "message": "Failed to obtain JDBC Connection; nested exception is java.sql.SQLException: null,  message from server: \"Host '192.168.64.1' is not allowed to connect to this MariaDB server\"",
    "path": "/users"
}

我的Spring Boot application.properties

# MySQL
spring.datasource.url=jdbc:mysql://192.168.64.2:3306/ctracker
spring.datasource.username=admin
spring.datasource.password=admin

logging.level.org.springframework=info
logging.level.org.springframework.jdbc=DEBUG

Phpmyadmin控制台：

我该如何解决此问题？

Spring启动堆栈跟踪，

我由phpmyadmin中的adding新用户解决了该问题，

1. 登录到phpMyADmin。
2. 转到特权。
3. 单击添加新用户。
4. 在“登录信息”区域中输入所需的访问信息（用户名，主机，密码）
5. 单击单选按钮以使用相同的名称创建数据库并授予所有特权。
6. 单击开始。
