spring-boot - AWS Lambda - Spring Boot 未处理请求

问题描述

我正在尝试在 AWS lambda 中将 Spring Boot 应用程序作为无服务器运行，并且在调用 lambda 函数时遇到异常。Spring Boot 应用程序成功运行，但似乎无法映射请求

        2018-09-25 06:11:50.717 INFO 1 --- [ main] o.s.j.e.a.AnnotationMBeanExporter : Registering beans for JMX exposure on startup
        2018-09-25 06:11:50.823 INFO 1 --- [ main] **my.service.Application : Started Application in 7.405 seconds (JVM running for 8.939)**

        2018-09-25 06:11:51.535 ERROR 1 --- [ main] s.p.i.s.AwsLambdaServletContainerHandler : Could not forward request

这是我的 StreamLambdaHandler java 文件。

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

            throw new RuntimeException("Could not initialize Spring Boot application", e);
        }
    }

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