在 Lambda 中部署的 Spring Boot 抛出“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

查看您的 Gradle 文件，您使用的是非常旧的过时的 AWS Serverless Java 容器版本，该版本与 Spring Boot 3.x 不兼容。

删除 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。您还可以在 https://github.com/awslabs/aws-serverless-java-container/tree/main/samples/springboot3/pet-store进行比较。

如果您将来遇到类似的超时挑战，您还可以启用 AWS X-Ray 或 OpenTelemetry 收集跟踪数据并查看时间损失的位置。
