<groupId>com.mysql</groupId> <artifactId>mysql-connector-j</artifactId>

这是Maven中用于引入MySQL数据库驱动的依赖项。groupId指定了依赖的组织或团队，artifactId指定了具体的库或模块名称。在这个例子中，`com.mysql`是MySQL组织的groupId，`mysql-connector-j`是MySQL Connector/J的artifactId，它是用于在Java应用程序中连接MySQL数据库的官方驱动程序。通过将此依赖项添加到您的Maven项目中，您可以使用MySQL数据库在Java应用程序中进行数据访问和操作。

<groupId>com.mysql</groupId> <artifactId>mysql-connector-j</artifactId> version

对不起，我之前的回答有误。你提到的是MySQL数据库连接器的Maven依赖。正确的依赖配置如下：

<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <version>8.0.23</version>
</dependency>

请注意，这里的`<version>`标签中的版本号可能需要根据你的具体需求进行调整。以上是MySQL Connector/J 8.0.23的依赖配置示例。

这是一个基于Spring Boot框架的Maven项目，它使用了Freemarker模板引擎、Spring JDBC、MyBatis、Druid连接池和MySQL数据库。它还包含了一些测试依赖项和MyBatis Generator插件用于生成Mapper接口和XML文件。此外，它还配置了Spring Boot插件和MyBatis Generator插件以方便开发和构建项目。
