Constructor Details

SimpleMongoRepository

public SimpleMongoRepository(MongoEntityInformation<T,ID> metadata,
 MongoOperations mongoOperations)

Creates a new SimpleMongoRepository for the given MongoEntityInformation and MongoTemplate.

Parameters:

metadata - must not be null.

mongoOperations - must not be null.

Method Details

save

public <S extends T> S save(S entity)

Specified by:

save in interface CrudRepository<T,ID>

saveAll

public <S extends T> List<S> saveAll(Iterable<S> entities)

Specified by:

saveAll in interface CrudRepository<T,ID>

Specified by:

saveAll in interface ListCrudRepository<T,ID>

findById

public Optional<T> findById(ID id)

Specified by:

findById in interface CrudRepository<T,ID>

existsById

public boolean existsById(ID id)

Specified by:

existsById in interface CrudRepository<T,ID>

findAll

public List<T> findAll()

Specified by:

findAll in interface CrudRepository<T,ID>

Specified by:

findAll in interface ListCrudRepository<T,ID>

findAllById

public List<T> findAllById(Iterable<ID> ids)

Specified by:

findAllById in interface CrudRepository<T,ID>

Specified by:

findAllById in interface ListCrudRepository<T,ID>

count

public long count()

Specified by:

count in interface CrudRepository<T,ID>

deleteById

public void deleteById(ID id)

Specified by:

deleteById in interface CrudRepository<T,ID>

delete

public void delete(T entity)

Specified by:

delete in interface CrudRepository<T,ID>

deleteAllById

public void deleteAllById(Iterable<? extends ID> ids)

Specified by:

deleteAllById in interface CrudRepository<T,ID>

deleteAll

public void deleteAll(Iterable<? extends T> entities)

Specified by:

deleteAll in interface CrudRepository<T,ID>

deleteAll

public void deleteAll()

Specified by:

findAll

public Page<T> findAll(Pageable pageable)

Specified by:

findAll in interface PagingAndSortingRepository<T,ID>

findAll

public List<T> findAll(Sort sort)

Specified by:

findAll in interface ListPagingAndSortingRepository<T,ID>

Specified by:

findAll in interface PagingAndSortingRepository<T,ID>

insert

public <S extends T> S insert(S entity)

Description copied from interface: MongoRepository

Inserts the given entity. Assumes the instance to be new to be able to apply insertion optimizations. Use the returned instance for further operations as the save operation might have changed the entity instance completely. Prefer using CrudRepository.save(Object) instead to avoid the usage of store-specific API.

Specified by:

insert in interface MongoRepository<T,ID>

Parameters:

entity - must not be null.

Returns:

the saved entity

insert

public <S extends T> List<S> insert(Iterable<S> entities)

Description copied from interface: MongoRepository

Inserts the given entities. Assumes the given entities to have not been persisted yet and thus will optimize the insert over a call to ListCrudRepository.saveAll(Iterable). Prefer using ListCrudRepository.saveAll(Iterable) to avoid the usage of store specific API.

Specified by:

insert in interface MongoRepository<T,ID>

Parameters:

entities - must not be null.

Returns:

the saved entities

findOne

public <S extends T> Optional<S> findOne(Example<S> example)

Specified by:

findOne in interface QueryByExampleExecutor<T>

findAll

public <S extends T> List<S> findAll(Example<S> example)

Description copied from interface: MongoRepository

Returns all entities matching the given Example. In case no match could be found an empty List is returned.
By default the Example uses typed matching restricting it to probe assignable types. For example, when sticking with the default type key (_class), the query has restrictions such as _class : { $in : [com.acme.Person] }.
To avoid the above mentioned type restriction use an UntypedExampleMatcher with Example.of(Object, org.springframework.data.domain.ExampleMatcher).

Specified by:

findAll in interface MongoRepository<T,ID>

Specified by:

findAll in interface QueryByExampleExecutor<T>

See Also:

• QueryByExampleExecutor.findAll(org.springframework.data.domain.Example)

findAll

public <S extends T> List<S> findAll(Example<S> example,
 Sort sort)

Description copied from interface: MongoRepository

Returns all entities matching the given Example applying the given Sort. In case no match could be found an empty List is returned.
By default the Example uses typed matching restricting it to probe assignable types. For example, when sticking with the default type key (_class), the query has restrictions such as _class : { $in : [com.acme.Person] }.
To avoid the above mentioned type restriction use an UntypedExampleMatcher with Example.of(Object, org.springframework.data.domain.ExampleMatcher).

Specified by:

findAll in interface MongoRepository<T,ID>

Specified by:

findAll in interface QueryByExampleExecutor<T>

• QueryByExampleExecutor.findAll(org.springframework.data.domain.Example, org.springframework.data.domain.Sort)

findAll

public <S extends T> Page<S> findAll(Example<S> example,
 Pageable pageable)

Specified by:

findAll in interface QueryByExampleExecutor<T>

count

public <S extends T> long count(Example<S> example)

Specified by:

count in interface QueryByExampleExecutor<T>

exists

public <S extends T> boolean exists(Example<S> example)

Specified by:

exists in interface QueryByExampleExecutor<T>

findBy

public <S extends T, R extends @Nullable Object> R findBy(Example<S> example,
 Function<FluentQuery.FetchableFluentQuery<S>, R> queryFunction)

Specified by:

findBy in interface QueryByExampleExecutor<T>
