无法访问org.springframework.beans.factory.support.DefaultListableBeanFactory

这个错误通常是由于Spring框架的配置问题导致的。 请检查您的Spring配置文件，确保所有的bean都正确配置。另外，也请确保您的依赖库与您正在使用的Spring版本兼容。如果这些都没有问题，您可以尝试重新构建您的项目并清除所有缓存，看看能否解决这个问题。如果问题仍然存在，您可以尝试在Spring日志中查找更多信息以帮助您解决问题。

Cannot map 'sendEmail' method

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。

这个错误是在使用 Spring Boot 的 WebSocket 功能时出现的，它的原因是无法找到 javax.websocket.server.ServerContainer。这个容器是 Java WebSocket API 中的一部分，但它不在所有的 Java 运行时环境中都存在。要解决这个问题，可以尝试在项目中添加 Tomcat 依赖，或者使用 Jetty 作为 WebSocket 容器。具体实现可以根据项目的实际情况进行调整。
