I am trying to create gRPC client in Quarkus. Did everything according to the documentation.

我正在尝试在Quarkus中创建GRPC客户端。一切都是按照文件做的。

Placed proto files in src/main/proto:
here is the content of the service file

将proto文件放置在src/main/proto中：以下是服务文件的内容

syntax = "proto3";

package userinfo.grpc;

import "UserInfoRequest.proto";
import "UserInfoResponse.proto";

service UserInfoService {
  rpc GetUserInfo (UserInfoRequest) returns (UserInfoResponse);
}

added to gradle following dependency:

添加到Gradle的依赖项如下：

implementation 'io.quarkus:quarkus-grpc'

When I built the project I saw my gRPC classes generated in

当我构建项目时，我看到我的GRPC类在

<projectFolder>\build\classes\java\quarkus-generated-sources\grpc\userinfo

My service that is using the gRPC client:

我使用GRPC客户端的服务：

@AllArgsConstructor
@LookupIfProperty(name = "auth.identity-service-enabled", stringValue = "true")
@ApplicationScoped
public class IdentityUserInfoProviderGrpc implements UserInfoProvider {
    @GrpcClient("userInfoService")
    UserInfoService userInfoService;

//business logic

The problem is that when I run the application I get:

问题是，当我运行应用程序时，我得到：

Blockquote
[error]: Build step io.quarkus.arc.deployment.ArcProcessor#validate threw an exception: jakarta.enterprise.inject.spi.DeploymentException: jakarta.enterprise.inject.UnsatisfiedResolutionException: Unsatisfied dependency for type userinfo.grpc.UserInfoService and qualifiers [@Default]
- java member: <my_package>.userinfo.grpc.IdentityUserInfoProviderGrpc():userInfoService
- declared on CLASS bean [types=[<my_package>.userinfo.UserInfoProvider, java.lang.Object, <my_package>.userinfo.grpc.IdentityUserInfoProviderGrpc], qualifiers=[@Default, @Any], target=<my_package>.userinfo.grpc.IdentityUserInfoProviderGrpc]
The following beans match by type, but none have matching qualifiers:
- Bean [class=userinfo.grpc.UserInfoService, qualifiers=[@Any, @io.quarkus.grpc.GrpcClient("userInfoService")]]

Was trying to add an empty META-INF/beans.xml file in the additional module src/main/resources as well as was trying to add Gradle Jandex plugin, as advised How to create a Jandex index in Quarkus for classes in a external module but did not help.

我试图在附加模块src/main/Resources中添加一个空的META-INF/beans.xml文件，并试图添加Gradle Jandex插件，如建议如何在Quarkus中为外部模块中的类创建Jandex索引，但没有帮助。

I have read few times all the documents Quarkus provided but have not found an explanation for this as I am doing everything as described.
Please help resolve this.

我已经读了几遍Quarkus提供的所有文件，但没有找到对此的解释，因为我正在做所描述的一切。请帮助解决此问题。

Much appreciated.

非常感谢。

This looks strange -- as we have plenty of test cases that check / test this.
e.g.

这看起来很奇怪--因为我们有很多测试用例来检查/测试这一点。例如：

• https://github.com/alesj/quarkus_cl130/blob/stacko1/app/src/main/java/com/alesj/qcl/app/Configuration.java#L28

Open up a GitHub issue on Quarkus GitHub with a reproducer, and I'll have a look ...

用复制者在Quarkus GitHub上打开GitHub问题，我会看看...

Ah, Clement found it -- you have a trailing space in your client name.

克莱门特找到了--你的客户名字后面有个空格。

@GrpcClient("userInfoService ") // <--- see space at the end

@GrpcClient(“userInfoService”)//<-见末尾空格

The following beans match by type, but none have matching qualifiers: - Bean [class=userinfo.grpc.UserInfoService, qualifiers=[@Any, @io.quarkus.grpc.GrpcClient("userInfoService")]]

以下Bean按类型匹配，但没有一个Bean具有匹配的限定符：-Bean[CLASS=Userinfo.grpc.UserInfoService，QUALIFIERS=[@ANY，@io.quarkus.grpc.GrpcClient(“userInfoService”)]]

Nice catch Clement!

接得好，克莱门特！
