Spring Boot déployé dans Lambda renvoie "statusCode": 502 Gateway timeout"

Question

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。

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）

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

Spring boot Lambda 请求流处理程序：（异步，因为我觉得 Lambda 最初需要很长时间才能启动）

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（我在此处添加了“task buildZip”以获取 zip 文件中的 build->“distributions”jar）

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

group = 'com.example'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '17'

repositories {
    mavenCentral()
}

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter-web'
    implementation 'org.springframework.boot:spring-boot-starter-test'
    implementation 'mysql:mysql-connector-java:8.0.32'
    implementation 'org.springframework.boot:spring-boot-starter-jdbc'
    implementation 'com.amazonaws:aws-lambda-java-core:1.2.2'
    implementation 'com.amazonaws:aws-lambda-java-events:3.11.1'
    implementation 'com.amazonaws.serverless:aws-serverless-java-container-spring:1.5.2'
}
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应用程序类：

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 启动控制器：

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 = &quot;*&quot;)
            @GetMapping(&quot;/searchDataByUser/{userno}&quot;)
            public List<TESTData> searchDataByUser(@PathVariable Integer userno) {
    
                List<TESTData> dataList = awstestServiceDAO.findDataByMemberNo(userno);
                return dataList;
            }
    
    }

Lambda 控制台：

添加处理程序为：com.example.awstest.handler.AWSLambdaHandler::handleRequest

Answer 1

En regardant vos fichiers Gradle, vous utilisez une version de conteneur Java sans serveur AWS très ancienne et obsolète qui n'est pas compatible avec Spring Boot 3.x.

Supprimer com.amazonaws.serverless:aws-serverless-java-container-spring:1.5.2 并将其替换为 com.amazonaws.serverless:aws-serverless-java-container -springboot3:2.0.0-M1. Vous pouvez également comparer sur https://github.com/awslabs/aws-serverless-java-container/tree/main/samples/springboot3/pet-store.

Si vous rencontrez des problèmes de délai d'attente similaires à l'avenir, vous pouvez également activer AWS X-Ray ou OpenTelemetry pour collecter des données de suivi et voir où le temps est perdu.
