Method Details

insert

<S extends T> S insert(S entity)

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.

Parameters:

entity - must not be null.

Returns:

the saved entity

Since:

1.7

insert

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

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.

Parameters:

entities - must not be null.

Returns:

the saved entities

Since:

1.7

findAll

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

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 QueryByExampleExecutor<T>
