如何解决我的 Lamda 函数部署 Spring Boot 中的错误？

Question

我想在 AWS Lamda 函数上运行 Spring Boot 控制器。我有一个如下所示的处理程序：

package com.amazonaws.serverless.sample.springboot3;


import com.amazonaws.serverless.exceptions.ContainerInitializationException;
import com.amazonaws.serverless.proxy.internal.testutils.Timer;
import com.amazonaws.serverless.proxy.model.AwsProxyRequest;
import com.amazonaws.serverless.proxy.model.AwsProxyResponse;
import com.amazonaws.serverless.proxy.spring.SpringBootLambdaContainerHandler;
import com.amazonaws.serverless.sample.springboot3.filter.CognitoIdentityFilter;
import com.amazonaws.services.lambda.runtime.Context;
import com.amazonaws.services.lambda.runtime.RequestStreamHandler;

import jakarta.servlet.DispatcherType;
import jakarta.servlet.FilterRegistration;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import java.util.EnumSet;


public class StreamLambdaHandler implements RequestStreamHandler {
    private static SpringBootLambdaContainerHandler<AwsProxyRequest, AwsProxyResponse> handler;
    static {
        try {
            handler = SpringBootLambdaContainerHandler.getAwsProxyHandler(Application.class);

            // For applications that take longer than 10 seconds to start, use the async builder:
            // handler = new SpringBootProxyHandlerBuilder<AwsProxyRequest>()
            //                    .defaultProxy()
            //                    .asyncInit()
            //                    .springBootApplication(Application.class)
            //                    .buildAndInitialize();

            // we use the onStartup method of the handler to register our custom filter
            handler.onStartup(servletContext -> {
                FilterRegistration.Dynamic registration = servletContext.addFilter("CognitoIdentityFilter", CognitoIdentityFilter.class);
                registration.addMappingForUrlPatterns(EnumSet.of(DispatcherType.REQUEST), true, "/*");
            });
        } catch (ContainerInitializationException e) {
            // if we fail here. We re-throw the exception to force another cold start
            e.printStackTrace();
            throw new RuntimeException("Could not initialize Spring Boot application", e);
        }
    }

    public StreamLambdaHandler() {
        // we enable the timer for debugging. This SHOULD NOT be enabled in production.
        Timer.enable();
    }

    @Override
    public void handleRequest(InputStream inputStream, OutputStream outputStream, Context context)
            throws IOException {
        handler.proxyStream(inputStream, outputStream, context);
    }
}

Gradle 构建如下所示：

apply plugin: 'java'

repositories {
  mavenLocal()
  mavenCentral()
}

sourceCompatibility = 11
targetCompatibility = 11

dependencies {
  implementation (
          implementation('org.springframework.boot:spring-boot-starter-web:2.7.13') {
            exclude group: 'org.springframework.boot', module: 'spring-boot-starter-tomcat'
          },
          'com.amazonaws.serverless:aws-serverless-java-container-springboot3:[2.0-SNAPSHOT,)',
  )
}

task buildZip(type: Zip) {
  from compileJava
  from processResources
  into('lib') {
    from(configurations.compileClasspath) {
      exclude 'tomcat-embed-*'
    }
  }
}

build.dependsOn buildZip

我使用此 Pulumi 代码将代码部署到 Lamda 函数：

import * as aws from "@pulumi/aws"
import * as pulumi from "@pulumi/pulumi";
import  {usersExecutionRole} from "./UsersExecutionRole"

const stack = pulumi.getStack()
const handler= "com.amazonaws.serverless.sample.springboot3.StreamLambdaHandler"


export const usersFunction = new aws.lambda.Function("users-function", {
    code: new pulumi.asset.FileArchive("../build/distributions/pet.zip"),   
    runtime: aws.lambda.Runtime.Java11,
    handler: handler,
    role: usersExecutionRole.arn,
    name: stack + '-' +"petsFunction",
    memorySize: 10240,
    timeout: 900,
    tracingConfig:{mode:"Active"},
    architectures:["arm64"],
    
        }

},

当我用curl调用Lamda函数时 卷曲https://512lnld1ve.execute-api.eu-north-1.amazonaws.com/dev/pets 我收到以下消息： {"message":"内部服务器错误"}%

ClodWatch 显示以下消息：
