base-packagespring-doc.cn

Defines the package to be scanned for repository interfaces that extend *Repository (the actual interface is determined by the specific Spring Data module) in auto-detection mode. All packages below the configured package are scanned, too. Wildcards are allowed.spring-doc.cn

find…By, read…By, get…By, query…By, search…By, stream…Byspring-doc.cn

General query method returning typically the repository type, a Collection or Streamable subtype or a result wrapper such as Page, GeoResults or any other store-specific result wrapper. Can be used as findBy…, findMyDomainTypeBy… or in combination with additional keywords.spring-doc.cn

exists…Byspring-doc.cn

Exists projection, returning typically a boolean result.spring-doc.cn

count…Byspring-doc.cn

Count projection returning a numeric result.spring-doc.cn

delete…By, remove…Byspring-doc.cn

Delete query method returning either no result (void) or the delete count.spring-doc.cn

…First<number>…, …Top<number>…spring-doc.cn

Limit the query results to the first <number> of results. This keyword can occur in any place of the subject between find (and the other keywords) and by.spring-doc.cn

…Distinct…spring-doc.cn

Use a distinct query to return only unique results. Consult the store-specific documentation whether that feature is supported. This keyword can occur in any place of the subject between find (and the other keywords) and by.spring-doc.cn

Tspring-doc.cn

A unique entity. Expects the query method to return one result at most. If no result is found, null is returned. More than one result triggers an IncorrectResultSizeDataAccessException.spring-doc.cn

Collection<T>spring-doc.cn

A Collection.spring-doc.cn

List<T>spring-doc.cn

Optional<T>spring-doc.cn

A Java 8 or Guava Optional. Expects the query method to return one result at most. If no result is found, Optional.empty() or Optional.absent() is returned. More than one result triggers an IncorrectResultSizeDataAccessException.spring-doc.cn

Option<T>spring-doc.cn

Either a Scala or Vavr Option type. Semantically the same behavior as Java 8’s Optional, described earlier.spring-doc.cn
