这是我下面的设置，

@SpringBootApplication
@ComponentScan(basePackages = "com.amazonaws.serverless.sample.springboot.controller")
public class Application extends SpringBootServletInitializer {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

public class LambdaHandler implements RequestStreamHandler {
    private SpringBootLambdaContainerHandler<AwsProxyRequest, AwsProxyResponse> handler;
    private static ObjectMapper mapper = new ObjectMapper();
    private Logger log = LoggerFactory.getLogger(LambdaHandler.class);

    @Override
    public void handleRequest(InputStream inputStream, OutputStream outputStream, Context context)
            throws IOException {
        if (handler == null) {
            try {
                handler = SpringBootLambdaContainerHandler.getAwsProxyHandler(Application.class);

            } catch (ContainerInitializationException e) {
                e.printStackTrace();
                outputStream.close();
                return;
            }
        }

        AwsProxyRequest request = mapper.readValue(inputStream, AwsProxyRequest.class);

        AwsProxyResponse resp = handler.proxy(request, context);
        mapper.writeValue(outputStream, resp);
        // just in case it wasn't closed by the mapper
        outputStream.close();
    }
}

每次当我尝试使用命令从本地控制台调用我的 lambda -“无服务器调用本地 -f hello”时，我都会遇到异常，

在行 - “handler = SpringBootLambdaContainerHandler.getAwsProxyHandler(Application.class);”

请帮我解决这个问题，我尝试了各种使用 aws lambda 进行引导设置的方法，但每次都失败了。请帮助我解决此问题或以任何其他方式帮助我进行设置。谢谢。

在您的日志中，我们可以看到：

没有类DefFoundError：javax/servlet/ServletContainerInitializer ClassNotFound异常：javax.servlet.ServletContainerInitializer

您能否检查一下库是否已加载，一定是缺少某些内容并且未正确加载

此外，类似的事情已经完成

<dependency>
    <groupId>com.amazonaws.serverless</groupId>
    <artifactId>aws-serverless-java-container-spring</artifactId>
    <version>1.3.2</version>
</dependency>

还要仔细检查步骤： https ://github.com/awslabs/aws-serverless-java-container/wiki/Quick-start---Spring-Boot

我遇到过同样的问题。我使用的是 0.2 版的 aws-serverless-java-container-spring 并且不得不切换到 1.3.2 版，因为之前的版本没有 SpringBootLambdaContainerHandler 类。
