यहाँ सबसे अच्छा समाधान है!
पहला चरण:
इंटरफ़ेस में एक कस्टम विधि जोड़ें!
增加一个自定义的方法
#कस्टम इंटरफ़ेस
/**
* 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);
}
कार्यान्वयन
दूसरा चरण:
अपनी कस्टम विधि के लिए कार्यान्वयन जोड़ें!
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);
}
}
कस्टम रिपॉजिटरी के लिए एक नया कारखाना बनाएं
/**
* 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;
}
}
}
इसे काम करें
<mongo:repositories base-package="com.***.mongodb"
factory-class="com.***.mongodb.custom.WootideRepositoryFactoryBean"/>
सफलता मिले!
