公开/部署多个处理程序 (quarkus-lambda)

Question

文档显示公开的处理程序（通过打包io.quarkus.amazon.lambda.runtime.QuarkusStreamHandler::handleRequest的应用程序）是通过quarkus.lambda.handler在application.properties. 但是就我而言，我想从同一项目部署多个处理程序。

有谁知道一种方法，或者是否有可能从 quarkus-lambda 项目中公开多个处理程序？

编辑：阅读完https://github.com/quarkusio/quarkus/blob/master/extensions/amazon-lambda/runtime/src/main/java/io/quarkus/amazon/lambda/runtime/AmazonLambdaRecorder.java#L89后现在看来确实不可能，对吗？

Answer 1

现在可以通过QUARKUS_LAMBDA_HANDLER为每个 lambda 函数设置环境变量来实现这一点。该环境变量将quarkus.lambda.handler在application.properties.

例如，如果您定义了多个处理程序，如下所示：

    @Named("Test")
    public class TestLambda implements RequestHandler<InputObject, OutputObject> {

        @Inject
        ProcessingService service;

        @Override
        public OutputObject handleRequest(InputObject input, Context context) {
            return new OutputObject().setRequestId("1").setResult("Test");
        }

    }

    @Named("Sample")
    public class SampleLambda implements RequestHandler<InputObject, OutputObject> {

        @Inject
        ProcessingService service;

        @Override
        public OutputObject handleRequest(InputObject input, Context context) {
            return new OutputObject().setRequestId("2").setResult("Sample");
        }
    }

您可以使用以下 SAM 模板构建单个项目并部署多个功能。
