问题 Most of the examples I've seen is using entityManager.createQuery or .createNativeQuery etc. Is there a way to have something like the following working? data class SummaryDto(val employeeName: String, val employerName: String) @Query("select e.name as employeeName, emp.name as employerName " + "from Employer e " + "inner join Employee emp on emp.employer_id = e.id ", nativeQuery = true) fun findSummaries(): List<SummaryDto> When I ran the above code I got this error No converter found

问题 I was confident that Spring Data and Spring Data JPA refers as same, but then I watched a tutorial on youtube about Spring Data and he is using JdbcTemplate in that tutorial. So I got confused there. I want to clarify that what is difference between Spring Data and JdbcTemplate ? JdbcTemplate and Spring Data JPA are parts of Spring Data ? 回答1: JdbcTemplate is part of the Spring Framework itself. Spring Data is the project which consists of multiple sub-projects where Spring Data JPA is one of

问题 I am trying to fetch records using custome query in SpringData repository. I want to use IN keyword to fetch objects according to ids of a nested object.

AND (t.businessType.text like ? or t.businessname like ?)") ArrayList<Business> findAllByAddressAddressidInAndBusinessTypeTextLikeOrBusinessnameLike(ArrayList<Long> ids,

问题 In my current project I'm using Spring Data JPA and I have more than 20 @Entity classes. I want to create repositories for them, but creating another classes, each for any model, with @Repository annotation seems to be some kind of overkill and a lot of "repeated" code - all repository classes will look like: @Repository public interface SomeModelRepository extends CrudRepository<SomeModel, Long> { } There is any way to create "automagically" those repositories? And specify only those that I

问题 There doesn't seem to be a specific standard way I can find online that makes @DataJpaTest to run correctly. Is it true that @DataJpaTest is not being used nowadays and all tests are run at the service or controller level using @SpringBootTest ? @Repository public interface MyBeanRepository extends JpaRepository<MyBean, Long> { } @Configuration @EnableJpaRepositories("com.app.repository.*") @ComponentScan(basePackages = { "com.app.repository.*" }) public class ConfigurationRepository { }
