In Lambda bereitgestellter Spring Boot löst „statusCode“ aus: 502 Gateway-Timeout“
<p>我将 Spring boot jar 文件（它具有 lambda 请求流处理程序）作为 zip 文件上传到 AWS Lambda。由于 zip 很大，我在 S3 中上传并在 AWS 控制台中创建此 Lambda 函数时给出了该链接。正如我到处读到的那样，这就是使用简单方法在 lambda 中部署 Spring Boot 服务的全部内容。我的 Spring Boot 服务中有 2 个 GET 端点。请在下面找到完整的 Spring boot 服务代码和 Lambda 屏幕截图。</p>
<p>错误：（出现超时错误，因此在 Lambda 测试中增加到 15 分钟，结果如下，似乎仍然无法正常工作）</p>
