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

Lambda 控制台:

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

测试功能:apigateway-awsproxy

Melihat fail Gradle anda, anda menggunakan versi bekas Java Tanpa Pelayan AWS yang sangat lama dan lapuk yang tidak serasi dengan Spring Boot 3.x.

Padamcom.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. Anda juga boleh membandingkan dihttps://github.com/awslabs/aws-serverless-java-container/tree/main/samples/springboot3/pet-store.

Jika anda menghadapi cabaran tamat masa yang sama pada masa hadapan, anda juga boleh mendayakanAWS X-RayatauOpenTelemetryuntuk mengumpul data penjejakan dan melihat di mana masa hilang.
