In Lambda bereitgestellter Spring Boot löst „statusCode“ aus: 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。
