在 Lambda 中部署的 Spring Boot 拋出'statusCode”：502 Gateway timeout”
P粉111227898
2023-08-28 23:12:36
<p>我將 Spring boot jar 文件（它具有 lambda 請求流處理程序）作為 zip 文件上傳到 AWS Lambda。由于 zip 很大，我在 S3 中上傳并在 AWS 控制臺中創(chuàng)建此 Lambda 函數(shù)時給出了該鏈接。正如我到處讀到的那樣，這就是使用簡單方法在 lambda 中部署 Spring Boot 服務的全部內容。我的 Spring Boot 服務中有 2 個 GET 端點。請在下面找到完整的 Spring boot 服務代碼和 Lambda 屏幕截圖。</p>
<p>錯誤：（出現(xiàn)超時錯誤，因此在 Lambda 測試中增加到 15 分鐘，結果如下，似乎仍然無法正常工作）</p>
<pre class="brush:php;toolbar:false;">Executing function: succeeded (logs )
