根据提供的引用内容,java.lang.ClassNotFoundException导致org.springframework.beans.factory.BeanCreationException: Error creating bean问题通常是由于依赖版本不兼容或缺少依赖导致的。在引用中,问题被解决了,因为spring-boot-starter-parent的版本被降低到与spring-cloud-starter-alibaba-nacos-config的版本相同。在引用中,版本不兼容的问题也被提到了。在引用中,错误信息提示需要重新运行应用程序以显示条件报告,并且应该启用调试模式以获取更多信息。这可能是由于缺少依赖项或版本不兼容导致的。
解决此问题的方法包括:
1.检查依赖项的版本是否兼容。
2.检查是否缺少依赖项。
3.尝试降低或升高依赖项的版本。
4.启用调试模式以获取更多信息。

这是一个关于Spring框架下bean创建时出现异常的错误,具体原因是在初始化CourseBaseMapper时,解析Mapper XML时出现了错误。错误的具体原因是在解析CourseBaseMapper.xml文件时,解析器无法找到类'com.xuecheng.content.model.dto.TeachplanDto',导致初始化失败。

这是一个比较复杂的错误,看起来是在Spring Boot应用程序启动时出现的。它的根本原因是依赖注入失败,导致无法创建一个名为'bannerController'的bean。在这个bean中,'bannerService'这个属性的依赖注入也失败了,从而导致了'bannerMapper'中的依赖注入失败。在'bannerMapper'中,由于无法创建'sqlSessionFactory' bean,导致出现了错误。
这个错误的具体原因可能有很多,但是从错误信息中可以看出,可能是由于缺少某些类或文件,或者配置文件中出现了错误。您需要检查您的代码和配置文件,找到导致这个错误的原因,并进行相应的修复。
