英文:
Spring boot deployed in Lambda throws "statusCode": 502 Gateway timeout"
问题
我将为您提供已翻译的部分：
错误：（由于超时错误，我在Lambda测试中将超时时间增加到了15分钟，以下是结果，似乎仍然无法正常工作）
执行函数：成功（日志）
{
"statusCode": 502,
"multiValueHeaders": {
"Content-Type": [
"application/json"
]
},
"body": "{\"message\":\"网关超时\"}",
"isBase64Encoded": false
}
Spring Boot Request Stream Handler for Lambda：（异步，因为我觉得Lambda在初始启动时需要更多时间）
public class StreamLambdaHandler implements RequestStreamHandler {
private SpringBootLambdaContainerHandler<AwsProxyRequest, AwsProxyResponse> handler;
public StreamLambdaHandler() throws ContainerInitializationException {
handler = new SpringBootProxyHandlerBuilder()
.defaultProxy()
.asyncInit()
.springBootApplication(SlowApplication.class)
.buildAndInitialize();
}
@Override
public void handleRequest(InputStream inputStream, OutputStream outputStream, Context context)
throws IOException {
handler.proxyStream(inputStream, outputStream, context);
}
}
build.gradle：（我在这里添加了“task buildZip”以将构建的“distributions” jar文件打包成zip文件）

I uploaded Spring boot jar file (it has lambda request stream handler) into AWS Lambda as zip file. Since the zip is big, I uploaded in S3 and given that link while creating this Lambda function in AWS Console. As I read everywhere that that's all the spring boot service deployment in lambda with the simple method. My spring boot service has 2 GET end points in it. Please find entire Spring boot service code and Lambda screenshots below.
Error: (It gave timeout error, so increased to 15 mins in Lambda test and the result is below, which seems to be not working still)
Executing function: succeeded (logs )

Spring boot Request Stream Handler for Lambda: (Asynchronous, as i felt Lambda takes much time to start initially)

你的Gradle文件中使用了一个非常老旧且不兼容Spring Boot 3.x的AWS Serverless Java Container版本。
请移除`com.amazonaws.serverless:aws-serverless-java-container-spring:1.5.2`，并替换为`com.amazonaws.serverless:aws-serverless-java-container-springboot3:2.0.0-M1`。你还可以在https://github.com/awslabs/aws-serverless-java-container/tree/main/samples/springboot3/pet-store 中找到一个完全可用的示例，用于进行比较。
如果将来遇到类似的超时挑战，你还可以启用[AWS X-Ray][1]或[OpenTelemetry][2]以收集跟踪数据，查看时间消耗在哪里。

Looking at your Gradle file you are using a very old outdated AWS Serverless Java Container version that is not compatible with Spring Boot 3.x.
Remove `com.amazonaws.serverless:aws-serverless-java-container-spring:1.5.2` and replace it with `com.amazonaws.serverless:aws-serverless-java-container-springboot3:2.0.0-M1`. You'll also find a fully working sample in https://github.com/awslabs/aws-serverless-java-container/tree/main/samples/springboot3/pet-store for comparison.
If you come across similar timeout challenges in the future, you can also enable [AWS X-Ray][1] or [OpenTelemetry][2] to gather tracing data and see where time is lost.
