Micronaut GraalVM本机映像中没有[com.mongodb.client.mongoClient]类型的bean

Question

我在GraalVm native-image（Micronaut框架）中遇到了MongoDB的问题。当我使用IDE和。jar进行部署时，所有工作都正常，没有任何异常。当我使用由Micronauts launcher./gradlew DockerBuildNative生成的标准Gradle任务创建本机映像并试图从数据库中获取实体时，找不到MongoClient。这是我的成绩。建造

    plugins {
        id("com.github.johnrengelman.shadow") version "7.0.0"
        id("io.micronaut.application") version "2.0.3"
    }
    
    version = "0.1"
    group = "com.project"
    
    repositories {
        mavenCentral()
    }
    
    micronaut {
        runtime("lambda")
        runtime("tomcat")
        testRuntime("junit5")
        processing {
            incremental(true)
            annotations("com.project*")
        }
    }
    
    dependencies {

        annotationProcessor("io.micronaut.openapi:micronaut-openapi")
        annotationProcessor("io.micronaut.security:micronaut-security-annotations")
    
    }
    
    
    application {
    //    mainClass.set("io.micronaut.function.aws.runtime.MicronautLambdaRuntime")
        m

ainClass.set("com.project.ProjectBackend")
}
jar {
    manifest {
        attributes(
                'Main-Class': 'com.project.ProjectBackend'
        )
    }
}
java {
    sourceCompatibility = JavaVersion.toVersion("11")
    targetCompatibility = JavaVersion.toVersion("11")
}

下面是我的DroneService.class，我试图从MongoDB中获取实体

@Singleton
public class DroneService {
    private MongoClient mongoClient;

    @Inject
    public DroneService(MongoClient mongoClient) {
        this.mongoClient = mongoClient;
    }

    public Drone findById() {
        return mongoClient
                .getDatabase("project_db")
                .getCollection("drones", Drone.class)
                .find(Filters.eq("_id", new ObjectId("61011ceaed86d207214941aa")))
                .first();
    }
}

micronaut:
  application:
    name: project
mongodb:
  uri: mongodb://admin:admin@localhost:27017/project_db?authSource=admin

有什么想法吗？

Answer 1

找到解决方案。Docker忽略了。properties文件，并且由于缺少连接URI，MongoClient bean没有创建。我的解决方案-使用graal SDK构建原生映像，而不是在docker容器内构建。
