无法生成quarkus应用程序：类型得依赖项不满足

Question

我试图将一个小型公司（多模块）RESTEasy JAX-RS应用程序移植到Quarkus，但我遇到了下面的错误。对公司模块有很多依赖关系，但我无法控制，但我试图遵循Quarkus的上下文和依赖关系注入指南（https://quarkus.io/guides/cdi-reference）。

操作系统:Ubuntu 18.04(WSL)

命令:./mvnw clean install-dskiptests

[ERROR] Failed to execute goal io.quarkus:quarkus-maven-plugin:1.9.2.Final:build (default) on project <REDACTED>: Failed to build quarkus application: io.quarkus.builder.BuildException: Build failure: Build failed due to errors
[ERROR]         [error]: Build step io.quarkus.arc.deployment.ArcProcessor#validate threw an exception: javax.enterprise.inject.spi.DeploymentException: Found 4 deployment problems:
...
[ERROR] [3] Unsatisfied dependency for type <REDACTED>.security.cryptography.CryptographyService and qualifiers [@Default]
[ERROR]         - java member: <REDACTED>.request.handlers.ConfigurationFileDownloadHandler#cryptographyService
[ERROR]         - declared on CLASS bean [types=[<REDACTED>.request.handlers.ConfigurationFileDownloadHandler, java.lang.Object], qualifiers=[@Default, @Any], target=<REDACTED>.request.handlers.ConfigurationFileDownloadHandler]

代码本身中的DI：

...
import <REDACTED>.security.cryptography.CryptographyService;
...

@ApplicationScoped
public class ConfigurationFileDownloadHandler {

...

    @Inject
    private CryptographyService cryptographyService;
...

依赖关系在子模块pom文件中声明（从下面的mvn dependency:tree可见）：

[INFO] +- <REDACTED>.security.cryptography:cryptography-service-api-jar:jar:1.5.1:compile

quarkus.index-dependency.cryptography.group-id=<REDACTED>.security.cryptography
quarkus.index-dependency.cryptography.artifact-id=cryptography-service-api-jar

感谢任何帮助。

我认为那些第三方企业类没有正确的注释可以被Quarkus CDI过程发现，这是对的吗？

是的，这应该是问题所在，如果cryptographyservice中没有CDI注释，即使它被Jandex索引了，它也是不可注入的。

解决方案是创建一个生产者，在bean工厂中生成cryptographyservicebean。

@Singleton
public class CryptographyServiceProducer {
    @Produces
    @ApplicationScoped
    public CryptographyService cryptographyService() {
        return new CryptographyService();
    }
}

作为参考，这里有一些关于CDI bean producer的文档:https://quarkus.io/guides/CDI#q-ok-you-said-that-there-are-mouse-king-of-beans
