Spring Boot PostgreSQL JPA @Query не работает

0 голосов
/ 08 октября 2019

Я изучаю spring boot, обращаясь к книге.

Я использовал в книге DB для H2, но я работал с PostgreSQL.

Используя метод запросав книге БД работают хорошо.

Однако, когда я начинаю использовать Annotation Query, она не работает.

Давайте посмотрим на код.

application.properties

spring.datasource.driver-class-name=org.postgresql.Driver
spring.datasource.url=jdbc:postgresql://Heroku Postgres URL
spring.datasource.username=Heroku Postgres username
spring.datasource.password=Heroku Postgres password

spring.jpa.hibernate.ddl-auto=update
spring.jpa.generate-ddl=false
spring.jpa.show-sql=true
spring.jpa.database-platform=org.hibernate.dialect.PostgreSQLDialect
spring.jpa.properties.hibernate.format_sql=true
spring.jpa.properties.hibernate.temp.use_jdbc_metadata_defaults = false

java-код 

public interface BoardRepository extends CrudRepository<Board, Long> {
    @Query("SELECT b FROM study.Board b WHERE b.title like %?1% ORDER BY b.seq DESC")
    List<Board> queryAnnotationTest1(String searchKeyword);

    /*@Query("SELECT b FROM study.Board b " 
    + "WHERE b.title like %:searchKeyword% " 
    + "ORDER BY b.seq DESC")
    List<Board> queryAnnotationTest2(@Param("searchKeyword") String searchKeyword);*/
}

@RunWith(SpringRunner.class)
@SpringBootTest
public class QueryMethodTest {
    @Autowired
    private BoardRepository repository;

    public void testQueryAnnotationTest1() {
        List<Board> boardList = repository.queryAnnotationTest2("test title 10");
        testPrintOutMethod(boardList);
    }


    private void testPrintOutMethod(List<Board> boardList) {
        System.out.println("test result");
        for (Board board : boardList) {
            System.out.println("---> " + board.toString());
        }
    }
}

Сообщение об ошибке.

Ниже приводится бесчисленное количество сообщений, но они не ограничены лимитом букв.

Это проблема запроса? Я пытался ввести запрос напрямую, но он работал нормально.

Но я не знаю, в чем проблема.

Используется ли PostgreSQL вместо H2, или естькакая-то другая ошибка?

Исключения говорят, что: Validation failed for query for method public abstract java.util.List com.limsr.testproject.persistence.BoardRepository.queryAnnotationTest1(java.lang.String)!, поэтому ошибка в синтаксисе запроса.

Я думаю, что ошибка в названии объекта. Попробуйте удалить study из study.Board. Таким образом, запрос будет выглядеть так: SELECT b FROM Board b WHERE b.title like %?1% ORDER BY b.seq DESC

На основе https://www.objectdb.com/java/jpa/entity/types#Entity_Classes_

Классы сущностей представлены в запросах именами сущностей. По умолчанию имя объекта - это неквалифицированное имя класса объекта (т. Е. Краткое имя класса, исключая имя пакета). Другое имя сущности может быть установлено явно с помощью атрибута name аннотации Entity. Имена сущностей должны быть уникальными. Когда два класса сущностей в разных пакетах имеют одно и то же имя класса, требуется явная настройка имени сущности, чтобы избежать коллизии.

Или, если у вас Board в качестве таблицы, а не в качестве имени сущности, и вызапрос является родным (не JPQL), вы можете использовать @Query("SELECT b FROM study.Board b WHERE b.title like %?1% ORDER BY b.seq DESC", nativeQuery = true)
