该实体的存储库:
package pl.umcs.lessonwiz.infrastructure;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.stereotype.Repository;
import pl.umcs.lessonwiz.domain.Course;
@Repository
public interface CourseRepository extends JpaRepository<Course, Integer> {
}
枚举类型:
package pl.umcs.lessonwiz.domain.enumeration;
public enum Days
{
FRIDAY, MONDAY, SATURDAY, SUNDAY, THURSDAY, TUESDAY, WEDNESDAY;
}

@Component
public class Test {
@Autowired

@Autowired
StudentFactory studentFactory;
@Autowired

@EventListener(ApplicationReadyEvent.class)
public void test()
{
System.out.println("Test method");
LocalTime time = LocalTime.now();
Course course = new Course("Title", time, time, Days.FRIDAY, 40, 1, 1);
System.out.println(course);
//studentRepository.save(studentFactory.createStudent("TEST", "TEST", "TEST"));
courseRepository.save(course);
}
}
看起来 Hibernate 无法理解我的枚举类型。我使用postgresql数据库。如果有人可以查看我的代码并给我一些建议，我将不胜感激。感谢您的回答。
最佳答案
只需将以下内容添加到您的 SQL 中:
CREATE CAST (character varying as days) WITH INOUT AS IMPLICIT;
这样，JPA 就可以继续将 Java Enum 类型 Days 的对象转换为 SQL 类型“varchar”，正如您用 @Enumerated(STRING) 告诉它的那样。然后 Postgres 会默默地将该 varchar 转换为其“days”类型。
