带有AWS lambda的原生Qukus不构建

Question

我正在尝试使用Quarkus native构建我的AWS Lambda。

我的设置是：

• GraalVM 19.3.0

当我跑步时

docker run -v /home/mypc/dev/java/quarkus/alexa_swear/target/<my project>-1.0-SNAPSHOT-native-image-source-jar:/project:z --user 1000:1000 --rm quay.io/quarkus/ubi-quarkus-native-image:19.2.1 -J-Djava.util.logging.manager=org.jboss.logmanager.LogManager --initialize-at-build-time= -H:InitialCollectionPolicy=com.oracle.svm.core.genscavenge.CollectionPolicy\$BySpaceAndTime -jar <my project>-1.0-SNAPSHOT-runner.jar -J-Djava.util.concurrent.ForkJoinPool.common.parallelism=1 -H:FallbackThreshold=0 -H:+ReportExceptionStackTraces -H:+AddAllCharsets -H:EnableURLProtocols=http -H:-JNI --no-server -H:-UseServiceLoaderFeature -H:+StackTrace <my project>-1.0-SNAPSHOT-runner

我得到以下错误：

Error: Image build request failed with exit status 1

上述错误被截断：相同的调用堆栈指向不同的不受支持的方法，例如java.lang.Thread.stop。

我的基本理解是，io.quarkus.amazon.lambda.runtime.Amazon LambdaRecorder$2.run（Amazon LambdaRecorder.java正在引用一些不受支持的方法，例如java.lang.Thread.resume（）。我也尝试过Quarkus19.2.1，但没有成功。

上面的命令是由mvn干净安装-Pnate-Dnative-image.docker-build=true-e执行的。

Answer 1

我终于找到了问题的原因。

在我的代码的非工作版本中，我使用了com的工厂。亚马逊。问AlexaSkill以某种方式注入入口点，如下所示：

package io.mirko.lambda;

import com.amazon.ask.AlexaSkill;
import com.amazon.ask.Skills;
import com.amazon.ask.dispatcher.request.handler.HandlerInput;
import com.amazon.ask.dispatcher.request.handler.RequestHandler;
import com.amazon.ask.model.RequestEnvelope;
import com.amazon.ask.model.ResponseEnvelope;
import com.amazon.ask.request.interceptor.GenericRequestInterceptor;
import io.mirko.lambda.handlers.*;

import javax.enterprise.context.ApplicationScoped;
import javax.enterprise.inject.Instance;
import javax.enterprise.inject.Produces;
import javax.inject.Inject;
import javax.inject.Named;
import java.util.*;
import java.util.stream.StreamSupport;


public class SkillFactory {
    @Inject
    Instance<RequestHandler> handlers;

    @Produces
    @ApplicationScoped
    @Named
    public AlexaSkill<RequestEnvelope, ResponseEnvelope> createSkill() {
        return Skills.standard()
                .addRequestHandlers(handlers.stream().toArray(RequestHandler[]::new))
                .addRequestInterceptor(new GenericRequestInterceptor<HandlerInput>() {
                    @Override
                    public void process(HandlerInput handlerInput) {
                        System.out.format("Processing %s\n", handlerInput.getRequest());
                    }
                })
                // Add your skill id below
                //.withSkillId("")
                .build();
    }
}

...

public class SwearStreamLambda extends SkillStreamHandler {
    @Named("swearStream")
        public SwearStreamLambda() {
            //noinspection unchecked
            super((AlexaSkill<RequestEnvelope, ResponseEnvelope>)
                getBean(new ParameterizedTypeImpl(AlexaSkill.class, RequestEnvelope.class, ResponseEnvelope.class)));

通过删除SkillFactory类并将其逻辑移到SwearStreamLambda类中，编译进行得很顺利。

一些注意事项：

1. 该问题与CDI无关，因为它在整个项目中大量使用

总而言之，我找不到问题的根本原因，但我认为我的问题已经解决了。

P、 在美国，最初的问题可以通过以下方式消除：

mvn干净的安装native-image.docker

请参见<代码>https://github.com/quarkusio/quarkus/issues/6395#issuecomment-570755587。

这并不能解决所有问题，因为必须配置Quarkus反射，但它解决了具体问题。
