【问题描述】：
我正在设置我的 spring 项目以使用 Spring Security。
我想使用 JDBC 身份验证并连接到 MySQL 数据库。
我在使用 @Autowired 创建 bean 时遇到问题。
我使用 Gradle 构建了我的 spring 项目。当我启动 tomcat 时，我看到如下错误消息。

源代码
我创建了 3 个 Java 配置类，如下所示。
- WebMvcConfig.class（实现 WebMvcConfigurer）
- WebSecurityConfig.class（扩展 WebSecurityConfigurerAdapter）
- DataSourceConfig.class（包括 @Bean 方法返回 BasicDataSource） （这3个类都在包“（我的顶级包名）.config中）

我的预期
我希望创建一个 BasicDataSource 对象并查看登录页面。

感谢您的评论。我已经添加了“build.gradle”（gradle的构建配置文件）的内容。
