Spring Data Mongo Repository::Fælles delt metode på tværs af alle Repo-spørgsmål

Her er den bedste løsning!

Trin et:
Tilføj en brugerdefineret metode til grænsefladen!
增加一个自定义的方法

#tilpasset grænseflade

/**
 * Basic Repository for common custom methods
 * @author liangping
 */

import java.io.Serializable;

import org.springframework.data.domain.Page;
import org.springframework.data.domain.Pageable;
import org.springframework.data.mongodb.core.query.Query;
import org.springframework.data.mongodb.repository.MongoRepository;
import org.springframework.data.repository.NoRepositoryBean;
import org.springframework.data.repository.PagingAndSortingRepository;

@NoRepositoryBean
public interface WootideRepositoryCustom <T, ID extends Serializable>
      extends PagingAndSortingRepository<T, ID>, MongoRepository<T, ID> {

      public Page<T> search(Query query, Pageable pageable);
}

Implementering

Trin to:
Tilføj redskab til din tilpassede metode!
实现你的自定义方法

/**
 * implement for wootide basic repository
 * @author liangping
 */

import java.io.Serializable;

import org.springframework.data.domain.Page;
import org.springframework.data.domain.PageImpl;
import org.springframework.data.domain.Pageable;
import org.springframework.data.mongodb.core.MongoOperations;
import org.springframework.data.mongodb.core.query.Query;
import org.springframework.data.mongodb.repository.query.MongoEntityInformation;
import org.springframework.data.mongodb.repository.support.SimpleMongoRepository;

public class WootideRepositoryImpl<T, ID extends Serializable> extends
        SimpleMongoRepository<T, ID> implements WootideRepositoryCustom<T, ID> {

    public WootideRepositoryImpl(MongoEntityInformation<T, ID> metadata,
            MongoOperations mongoOperations) {
        super(metadata, mongoOperations);
    }

    @Override
    public Page<T> search(Query query, Pageable pageable) {
        long total = this.getMongoOperations().count(query, this.getEntityInformation().getJavaType() );
        return new PageImpl<T>(this.getMongoOperations().find(query.with(pageable), this.getEntityInformation().getJavaType()), pageable, total);
    }

}

Opret en ny fabrik til brugerdefineret lager

/**
 * Repository Factory for all Subrepository
 * @author liangping
 */

import java.io.Serializable;

import org.springframework.data.mongodb.core.MongoOperations;
import org.springframework.data.mongodb.core.mapping.BasicMongoPersistentEntity;
import org.springframework.data.mongodb.core.mapping.MongoPersistentEntity;
import org.springframework.data.mongodb.repository.MongoRepository;
import org.springframework.data.mongodb.repository.query.MongoEntityInformation;
import org.springframework.data.mongodb.repository.support.MappingMongoEntityInformation;
import org.springframework.data.mongodb.repository.support.MongoRepositoryFactory;
import org.springframework.data.mongodb.repository.support.MongoRepositoryFactoryBean;
import org.springframework.data.repository.core.RepositoryMetadata;
import org.springframework.data.repository.core.support.RepositoryFactorySupport;
import org.springframework.data.util.ClassTypeInformation;
import org.springframework.data.util.TypeInformation;

public class WootideRepositoryFactoryBean<R extends MongoRepository<T, I>, T, I extends Serializable>
        extends MongoRepositoryFactoryBean<R, T, I> {

    @Override
    protected RepositoryFactorySupport getFactoryInstance(
            MongoOperations operations) {
        return new WootideMongoRepositoryFactory<T,I>( operations );
    }

    private static class WootideMongoRepositoryFactory<T, ID extends Serializable>
            extends MongoRepositoryFactory {

        private MongoOperations mongo;
        public WootideMongoRepositoryFactory(MongoOperations mongoOperations) {
            super(mongoOperations);
            this.mongo = mongoOperations;
        }

        @SuppressWarnings("unchecked")
        protected Object getTargetRepository(RepositoryMetadata metadata) {

            TypeInformation<T> information =  ClassTypeInformation.from((Class<T>)metadata.getDomainType());
            MongoPersistentEntity<T> pe = new BasicMongoPersistentEntity<T>(information);
            MongoEntityInformation<T,ID> mongometa = new MappingMongoEntityInformation<T, ID>(pe);

            return new WootideRepositoryImpl<T, ID>( mongometa,  mongo);
        }

        protected Class<?> getRepositoryBaseClass(RepositoryMetadata metadata) {
            return WootideRepositoryCustom.class;
        }
    }
}

Få det til at virke

<mongo:repositories base-package="com.***.mongodb" 
factory-class="com.***.mongodb.custom.WootideRepositoryFactoryBean"/>

Held og lykke!祝你好运！
