启动失败是 MyBatis 与 Spring Boot 3 的兼容问题导致的： userMapper Bean 创建时触发 Invalid value type for attribute 'factoryBeanObjectType': java.lang.String

异常如图：

- 根因是 mybatis-plus-boot-starter:3.5.6 传递引入了不兼容的 org.mybatis:mybatis-spring:2.1.2 ，该版本与 Spring Framework 6（Spring Boot 3）不兼容。
- 处理措施：
- 移除了接口模块中重复且冲突的 mybatis-spring-boot-starter 依赖，避免双重扫描与配置（ toast-user-interface/pom.xml ）。
- 在顶层 pom.xml 的 dependencyManagement 强制覆盖 MyBatis 相关版本：
- org.mybatis:mybatis-spring:3.0.5
- org.mybatis:mybatis:3.5.19
- 保持 mybatis-plus-boot-starter 使用现有版本，通过依赖管理解决兼容性。
