1. 问题现象与背景分析最近在Azure Web App上部署Spring Boot应用时遇到了一个典型问题通过GitHub Actions自动化部署Jar包到App Service时持续收到400 Bad Request错误。这个错误看似简单但排查过程却涉及多个技术栈的交叉验证。作为经历过完整排查流程的开发者我把这个踩坑过程整理成详细指南。400错误本质上表示服务器无法理解客户端请求。在Azure App Service的上下文中当部署请求被拒绝时通常意味着部署包格式不符合规范认证凭据失效目标资源配置错误网络策略限制2. 完整错误链分析2.1 错误日志关键信息典型的错误输出包含以下关键字段Error: Failed to deploy web package to App Service.
