[xxxx.xxxx.xxxx] 类型的 bean 不存在。确保该 bean 未被 bean 要求禁用 Micronaut 消息传递应用程序

Question

我有以下项目结构

主项目DEMO依赖于Gradle项目SERVICE实现了[=42]的接口=]PORT 项目.

演示 build.gradle

dependencies {
    implementation project(':port')
    runtime project(':service')
}

服务build.gradle

dependencies {
    implementation project(':port')

    implementation("javax.annotation:javax.annotation-api:1.3.2")
    compile "io.micronaut:micronaut-inject:2.4.0"
    annotationProcessor "io.micronaut:micronaut-inject-java:2.4.0"
}

服务class实现IStartUpPort

@Singleton
public class StartUpService implements IStartUpPort {
    @Override
    public void toUpperCase() {
        System.out.println("Something happened");
    }
}

端口build.gradle

dependencies {
    implementation("javax.annotation:javax.annotation-api:1.3.2")
    compile "io.micronaut:micronaut-inject:2.4.0"
    annotationProcessor "io.micronaut:micronaut-inject-java:2.4.0"
}

端口接口

public interface IStartUpPort {
    void toUpperCase();
}

在主项目中，我在服务项目上做DI，遇到异常

@Singleton
public class StartUp implements ApplicationEventListener<StartupEvent> {
    private final IStartUpPort iStartUpPort;

    public StartUp(IStartUpPort iStartUpPort) {
        this.iStartUpPort = iStartUpPort;
    }

    @Override
    public void onApplicationEvent(StartupEvent event) {
        iStartUpPort.toUpperCase();
    }
}

异常

Message: No bean of type [fete.bird.IStartUpPort] exists. Make sure the bean is not disabled by bean requirements (enable trace logging for 'io.micronaut.context.condition' to check) and if the bean is enabled then ensure the class is declared a bean and annotation processing is enabled (for Java and Kotlin the 'micronaut-inject-java' dependency should be configured as an annotation processor).

这是一个 Micronuat 消息应用程序存储库，可以在此处找到 https://github.com/anandjaisy/MessengingMultiGradleProject

Answer 1

链接库中的当前代码已配置，如果正确构建和执行应用程序，问题中显示的错误将不会发生。

克隆存储库：

$ git clone git@github.com:anandjaisy/MessengingMultiGradleProject.git

构建服务：

$ cd MessengingMultiGradleProject
$ ./gradlew assemble

运行服务：

$ java -jar build/libs/demo-0.1-all.jar
