Manuel Núñez commented on IGNITE-13005: --------------------------------------- [~ilyak] done. > Spring Data 2 - "JPA style" and working with multiple Ignite instances on > same JVM > ---------------------------------------------------------------------------------- > > Key: IGNITE-13005 > URL: https://issues.apache.org/jira/browse/IGNITE-13005 > Project: Ignite > Issue Type: Improvement > Components: spring > Affects Versions: 2.7.6, 2.8.1 > Reporter: Manuel Núñez > Assignee: Manuel Núñez > Priority: Major > Labels: spring-data > Time Spent: 10m > Remaining Estimate: 0h > > I have it working for Spring Data 2 (2.7.6, 2.8.1) module with some > interesting improvements. > Code is 100% compatible with previous versions. > [https://github.com/hawkore/ignite-hk/tree/master/modules/spring-data-2.0] > * Supports multiple ignite instances on same JVM (@RepositoryConfig). > * Supports query tuning parameters in {{@Query}} annotation > * Supports projections > * Supports {{Page}} and {{Stream}} responses > * Supports Sql Fields Query resultset transformation into the domain entity > * Supports named parameters ({{:myParam}}) into SQL queries, declared using > {{@Param("myParam")}} > * Supports advanced parameter binding and SpEL expressions into SQL queries: > ** *Template variables*: > *** {{#entityName}} - the simple class name of the domain entity > ** *Method parameter expressions*: Parameters are exposed for indexed access > ({{[0]}} is the first query method's param) or via the name declared using > {{@Param}}. The actual SpEL expression binding is triggered by {{?#}}. > Example: {{?#\{[0]\}} or {{?#\{#myParamName\}}} > ** *Advanced SpEL expressions*: While advanced parameter binding is a very > useful feature, the real power of SpEL stems from the fact, that the > expressions can refer to framework abstractions or other application > components through SpEL EvaluationContext extension model. > * Supports SpEL expressions into Text queries ({{TextQuery}}). > Some examples: > {code:java} > // Spring Data Repositories using different ignite instances on same JVM > @RepositoryConfig(igniteInstance = "FLIGHTS_BBDD", cacheName = "ROUTES") > public interface FlightRouteRepository extends IgniteRepository<Route, > String> { > ... > } > @RepositoryConfig(igniteInstance = "GEO_BBDD", cacheName = "POIS") > public interface PoiRepository extends IgniteRepository<Poi, String> { > ... > } > {code} > {code:java} > // named parameter > @Query(value = "SELECT * from #{#entityName} where email = :email") > User searchUserByEmail(@Param("email") String email); > {code} > {code:java} > // indexed parameters > @Query(value = "SELECT * from #{#entityName} where country = ?#{[0] and city > = ?#{[1]}") > List<User> searchUsersByCity(@Param("country") String country, @Param("city") > String city, Pageable pageable); > {code} > {code:java} > // ordered method parameters > @Query(value = "SELECT * from #{#entityName} where email = ?") > User searchUserByEmail(String email); > {code} > {code:java} > // Advanced SpEL expressions > @Query(value = "SELECT * from #{#entityName} where uuidCity = > ?#{mySpELFunctionsBean.cityNameToUUID(#city)}") > List<User> searchUsersByCity(@Param("city") String city, Pageable pageable); > {code} > {code:java} > // textQuery - evaluated SpEL named parameter > @Query(textQuery = true, value = "email: #{#email}") > User searchUserByEmail(@Param("email") String email); > {code} > {code:java} > // textQuery - evaluated SpEL named parameter > @Query(textQuery = true, value = "#{#textToSearch}") > List<User> searchUsersByText(@Param("textToSearch") String text, Pageable > pageable); > {code} > {code:java} > // textQuery - evaluated SpEL indexed parameter > @Query(textQuery = true, value = "#{[0]}") > List<User> searchUsersByText(String textToSearch, Pageable pageable); > {code} > {code:java} > // Static Projection > @Query(value = > "SELECT DISTINCT m.id, m.name, m.logos FROM #{#entityName} e > USE INDEX (ORIGIN_IDX) INNER JOIN \"flightMerchants\".Merchant m ON m" > + "._key=e" > + ".merchant WHERE e.origin = :origin and e.disabled = > :disabled GROUP BY m.id, m.name, m.logos ORDER BY m.name") > List<AProjection> searchMerchantsByOrigin(@Param("origin") String origin, > @Param("disabled") boolean disabled); > {code} > {code:java} > // Dynamic Projection > @Query(value = > "SELECT DISTINCT m.id, m.name, m.logos FROM #{#entityName} e > USE INDEX (ORIGIN_IDX) INNER JOIN \"flightMerchants\".Merchant m ON m" > + "._key=e" > + ".merchant WHERE e.origin = :origin and e.disabled = > :disabled GROUP BY m.id, m.name, m.logos ORDER BY m.name") > <P> List<P> searchMerchantsByOrigin(Class<P> projection, @Param("origin") > String origin, @Param("disabled") boolean disabled); > {code} -- This message was sent by Atlassian Jira (v8.3.4#803005)
