问题

I am making grpc client using net.devh.grpc-client-spring-boot-starter

Client:

@Service
public class SystemService {
    @GrpcClient("handyman-client")
    StatusServiceGrpc.StatusServiceBlockingStub handymanClient;

    public VersionResponse getHandymanVersion() {
        return handymanClient.getVersion(Empty.newBuilder().build());
    }
}

application.yaml:

grpc:
  client:
    handyman-client:
      address: static://localhost:8080
      negotiationType: plaintext

In runtime handymanClient is null. Tried spring boot versions from 3.0.0 to 3.0.2. Lowering the spring boot version to 2.7.0 solves the problem - the client is being created now.

Is there a workaround to make it work on spring boot 3?

build.gradle:

plugins {
    id 'java'
    id 'org.springframework.boot' version '3.0.0'
    id 'io.spring.dependency-management' version '1.1.0'
    id "com.google.protobuf" version "0.9.2"
}

group = 'hello.grpc'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '17'

configurations {
    compileOnly {
        extendsFrom annotationProcessor
    }
}

repositories {
    mavenCentral()
}

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter-actuator'
    implementation 'org.springframework.boot:spring-boot-starter-web'
    compileOnly 'org.projectlombok:lombok'
    annotationProcessor 'org.projectlombok:lombok'
    testImplementation 'org.springframework.boot:spring-boot-starter-test'
    implementation 'io.micrometer:micrometer-registry-prometheus'
    implementation 'javax.annotation:javax.annotation-api:1.3.2'

    implementation group: 'net.devh', name: 'grpc-client-spring-boot-starter', version: '2.13.0.RELEASE'
    implementation group: 'io.grpc', name: 'grpc-stub', version: '1.53.0'
    implementation group: 'io.grpc', name: 'grpc-protobuf', version: '1.53.0'
}

sourceSets {
    main {
        java {
            srcDirs 'build/generated/source/proto/main/grpc'
            srcDirs 'build/generated/source/proto/main/java'
        }
    }
}

protobuf {
    protoc {
        artifact = 'com.google.protobuf:protoc:4.0.0-rc-2'
    }
    plugins {
        grpc {
            artifact = 'io.grpc:protoc-gen-grpc-java:1.53.0'
        }
    }
    generateProtoTasks {
        all()*.plugins {
            grpc {}
        }
    }
}

tasks.named('test') {
    useJUnitPlatform()
}

springBoot {
    buildInfo()
}

Hope this helps!

根据这个问题，你必须在你的项目中使用以下配置：

import org.springframework.boot.autoconfigure.ImportAutoConfiguration;
import org.springframework.context.annotation.Configuration;

@Configuration
@ImportAutoConfiguration({

自从Spring Boot 3中更改了自动配置，META-INF/spring.factories 已更新为 META-INF/spring/org.springframework.boot.autoconfigure.AutoConfiguration.imports。这个更新阻止了grpc-client 的自动装配。在最新的主分支上，已添加了Spring Boot 3的自动装配。您可以下载源代码并进行编译和安装。
