Spring boot deployed in Lambda throws "statusCode": 502 Gateway timeout"

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 )
    {
  "statusCode": 502,
  "multiValueHeaders": {
    "Content-Type": [
      "application/json"
    ]
  },
  "body": "{\"message\":\"Gateway timeout\"}",
  "isBase64Encoded": false
}

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

    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 ( I added "task buildZip" here to get build->"distributions" jar in zip file)

plugins {
    id 'java'
    id 'org.springframework.boot' version '3.1.0'
    id 'io.spring.dependency-management' version '1.1.0'
}

group = 'com.example'

repositories {
    mavenCentral()

    implementation 'org.springframework.boot:spring-boot-starter-test'
    implementation 'mysql:mysql-connector-java:8.0.32'

task buildZip(type: Zip) {
    into('lib') {
        from(jar)
        from(configurations.runtimeClasspath)
    }
}
tasks.named('test') {
    useJUnitPlatform()
}
jar {
    duplicatesStrategy = DuplicatesStrategy.EXCLUDE
    manifest {
        attributes "Main-Class": "com.example.awstest"
    }

    from {
        configurations.runtimeClasspath.collect { it.isDirectory() ? it : zipTree(it) }
    }
}

Spring Boot Application Class:

package com.example.awstest.client;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
@ComponentScan ("com.example.awstest")
public class AWSTestApplication  extends SpringBootServletInitializer {

    public static void main(String[] args) {
        SpringApplication.run(AWSTestApplication.class, args);
    }
}

Spring Boot Controller:

package com.example.awstest.controller;

@RestController

public class AWSTestController {

        @Autowired
            private AWSTestServiceDAO awstestServiceDAO;
    
            @CrossOrigin(origins = "*")
            @GetMapping("/searchAllData")
            public List<TESTData> searchAllData() {
    
                List<TESTData> dataList = awstestServiceDAO.getAllData();
                return dataList;
             }
    
            @CrossOrigin(origins = "*")
            @GetMapping("/searchDataByUser/{userno}")
            public List<TESTData> searchDataByUser(@PathVariable Integer userno) {
    
                List<TESTData> dataList = awstestServiceDAO.findDataByMemberNo(userno);
                return dataList;
            }
    
    }

Added handler as: com.example.awstest.handler.AWSLambdaHandler::handleRequest

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 or OpenTelemetry to gather tracing data and see where time is lost.
