spring boot 启动失败了， 看第二张图的日志是 请求 nacos的实例失败了

根据您提供的信息，"o.s.boot.SpringApplication：Application run failed" 是Spring Boot框架在启动应用程序时报告的错误。

这个错误信息本身并不足够详细，因此我们需要更多的上下文信息来确定问题的根本原因。以下是一些常见的可能原因和解决方法，您可以逐个尝试以找出问题所在：

  1. 端口冲突：确保您的应用程序使用的端口未被其他进程占用。您可以尝试更改应用程序的端口号，或者使用一些工具（如lsof或netstat）来检查该端口是否已被占用。

  2. 依赖项问题：检查您的应用程序的依赖项是否正确配置和引入。确保您的构建工具（如Maven或Gradle）正确下载和管理所需的依赖项。

  3. 数据库连接问题：如果您的应用程序需要连接数据库，确保数据库配置正确，并且数据库服务正在运行。检查连接字符串、用户名和密码等配置是否正确。

  4. 日志记录：查看应用程序的详细日志以获取更多有关错误的信息。Spring Boot通常会将日志输出到控制台或特定的日志文件中。检查这些日志文件

PS：可以的话发截图而不是拍照，希望可以帮到你
