fete.bird.repository.GenericRepository位于加载程序“ app”的未命名模块中

问题描述

接口

package fete.bird.repository;

import com.mongodb.reactivestreams.client.MongoCollection;

public interface IGenericRepository<T> {
    MongoCollection<T> getCollection(String collectionName,Class<T> typeParameterClass);
}

实施

package fete.bird.repository;

import com.mongodb.reactivestreams.client.MongoClient;
import com.mongodb.reactivestreams.client.MongoCollection;


import javax.inject.Singleton;

@Singleton
public class GenericRepository<T> implements IGenericRepository<T>{
    private final MongoClient mongoClient;

    public GenericRepository(MongoClient mongoClient) {
        this.mongoClient = mongoClient;
    }

    @Override
    public MongoCollection<T> getCollection(String collectionName,Class<T> typeParameterClass) {
        return mongoClient
                .getDatabase("FeteBird-Product")
                .getCollection(collectionName,typeParameterClass);
    }
}

例外

使用界面

@KafkaListener(offsetReset = OffsetReset.EARLIEST)
public class ProductListener {
    private static final Logger LOG = LoggerFactory.getLogger(ProductListener.class);
    private final IGenericRepository<Product> repository;

    public ProductListener(IGenericRepository<Product> repository) {
        this.repository = repository;
    }

    @Topic(ProductTopicConstants.GET_FREE_TEXT_SEARCH)
    public Flowable<List<Product>> findByFreeText(String text) {
            var item = this.repository.getCollection("product",Product.class);
        return Flowable.just(List.of(new Product()));
    }
}

根据语句Caused by: java.lang.IncompatibleClassChangeError: class fete.bird.repository.GenericRepository$Intercepted can not implement fete.bird.repository.GenericRepository,because it is not an interface (fete.bird.repository.GenericRepository is in unnamed module of loader 'app')

，我不知道是什么原因造成的

但是我还没有实现GenericRepository，我已经实现了代码中的IGenericRepository
