我可以为这个问题做些什么？我需要一些其他文件给你看吗？提前谢谢你！

编辑：整个项目：https://github.com/Oyo31/backend

编辑 2：我更新了所有 Spring，更改了一些依赖项，这对这个问题很有帮助。我设法使用 Maven 安装。我现在只有一个问题，当我启动它时。仍在努力！

最终编辑：我设法启动它。现在，是时候纠正应用程序中的一些错误了！谢谢大家！

【问题讨论】：

启动项目使用1.2.7.RELEASE spring boot版本有什么注意事项吗？这个版本有点过时了。

没有看到您的评论。那是我最初的问题！现在，我有一个新的

【参考方案1】：

我在初始配置中发现了一些问题：

如果您不打算添加与 BOM 不同的版本，则无需添加此依赖项。

<dependency>
   <groupId>org.springframework</groupId>
   <artifactId>spring-web</artifactId>
   <version>5.1.2.RELEASE</version>
</dependency>

这个依赖已经自带了

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>

你不需要

<dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-tomcat</artifactId>
   <scope>provided</scope>
</dependency>

SpringBootServletInitializer 的扩展仅在您想通过战争部署到服务器时才需要

【讨论】：

感谢您的帮助，但没有第一个，它添加了一些错误。我为整个项目编辑了主线程并从 Github 上放了一个链接。
