共享微服务，Micronaut 错误 - 发现多个可能的候选 bean

发布于 2025-01-18 01:02:50 字数 11688 浏览 5 评论 0原文

我正在尝试使用 Micronaut 构建一个简单的 API 来获取所有用户，该 API 在本地主机上正常工作，但面临以下 docker 镜像问题 -

内部服务器错误：实例化 [com.cawstudios.authentication_service.controllers.UserController] 类型的 bean 时出错\n\n消息：找到多个可能的 bean 候选对象：[io.micronaut.aop.InterceptorRegistry、io.micronaut.aop.InterceptorRegistry ]\n采用的路径： new UserController(UserRepository userRepository) -->新的 UserController([UserRepository userRepository]

​​结构 -

Authentication-service
 - Controllers
   - UserController
 - Reposotories
   - UserRepository

Common 
 - Entities
   UserEntity

我需要跨多个微服务使用 1 DB。 Common 是一个共享服务，我试图将所有实体放在其中，以便任何微服务都可以通过添加 common 作为其依赖项来使用它们。

UserController

import com.cawstudios.authentication_service.repositories.UserRepository;

import com.cawstudios.common.entities.UserEntity;
import io.micronaut.http.HttpResponse;
import io.micronaut.http.MediaType;
import io.micronaut.http.annotation.Controller;
import io.micronaut.http.annotation.Get;

import java.util.List;

@Controller("/users")
public class UserController {

    private final UserRepository userRepository;

    public UserController(final UserRepository userRepository) {
        this.userRepository = userRepository;
    }

    @Get("/")
    public HttpResponse<List<UserEntity>> getUsers() {
        List<UserEntity> userModels = this.userRepository.findAll();
        return HttpResponse.ok(userModels);
    }

UserRepository

import com.cawstudios.common.entities.UserEntity;
import io.micronaut.data.annotation.Repository;
import io.micronaut.data.repository.CrudRepository;

import java.util.List;
import java.util.UUID;

@Repository
public interface UserRepository extends CrudRepository<UserEntity, UUID> {
    @Override
    List<UserEntity> findAll();
}

原文

I am trying to build a simple API using Micronaut to fetch all users, which works properly on localhost, but facing the below issue with docker image -

Internal Server Error: Error instantiating bean of type [com.cawstudios.authentication_service.controllers.UserController]\n\nMessage: Multiple possible bean candidates found: [io.micronaut.aop.InterceptorRegistry, io.micronaut.aop.InterceptorRegistry]\nPath Taken: new UserController(UserRepository userRepository) --> new UserController([UserRepository userRepository]

Structure -

Authentication-service
 - Controllers
   - UserController
 - Reposotories
   - UserRepository

Common 
 - Entities
   UserEntity

I have a requirement to use 1 DB across multiple microservices.
Common is a shared service where I am trying to put all the entities so that any microservice can use them by adding common as their dependency.

UserController

import com.cawstudios.authentication_service.repositories.UserRepository;

import com.cawstudios.common.entities.UserEntity;
import io.micronaut.http.HttpResponse;
import io.micronaut.http.MediaType;
import io.micronaut.http.annotation.Controller;
import io.micronaut.http.annotation.Get;

import java.util.List;

@Controller("/users")
public class UserController {

    private final UserRepository userRepository;

    public UserController(final UserRepository userRepository) {
        this.userRepository = userRepository;
    }

    @Get("/")
    public HttpResponse<List<UserEntity>> getUsers() {
        List<UserEntity> userModels = this.userRepository.findAll();
        return HttpResponse.ok(userModels);
    }

UserRepository

import com.cawstudios.common.entities.UserEntity;
import io.micronaut.data.annotation.Repository;
import io.micronaut.data.repository.CrudRepository;

import java.util.List;
import java.util.UUID;

@Repository
public interface UserRepository extends CrudRepository<UserEntity, UUID> {
    @Override
    List<UserEntity> findAll();
}
