org.springframework.boot.autoconfigure和org.springframework.beans.factory.support.BeanDefinitionBuilder兼容版本

org.springframework.boot.autoconfigure和org.springframework.beans.factory.support.BeanDefinitionBuilder的兼容版本是根据Spring Boot版本来确定的。具体来说，org.springframework.boot.autoconfigure和org.springframework.beans.factory.support.BeanDefinitionBuilder是Spring Boot框架中的不同模块，它们的版本兼容性取决于Spring Boot版本的发布和更新。

这个错误是因为在Spring的Web MVC配置中，有一个方法（com.example.spring.controller.Others.SendEmail）被映射到了多个URL上，导致无法确定应该映射到哪个URL。这种情况被称为“模糊映射（Ambiguous mapping）”。需要修改映射关系，确保每个方法只被映射到单一的URL上。

这个错误是由于无法建立 Hibernate 的 SessionFactory 导致的。根据错误信息，可能是由于无法建立 JDBC 连接导致的。

你可以检查以下几点：

1. 数据库连接信息是否正确，包括数据库地址、用户名、密码等。
2. 数据库是否已经启动。
3. 数据库是否正确设置了字符集、时区等信息。
4. 是否存在防火墙等网络安全设置导致无法连接数据库。

如果以上检查都没有问题，可以尝试在代码中添加调试信息，查看具体出错的位置，并尝试解决问题。
