我试图使用Spring data JDBC将一个名为讲师的实体持久化到H2内存数据库，如果我手动创建表一切都工作正常，否则我会得到这个错误(我在底部添加了整个错误堆栈跟踪):
org.h2.jdbc.JdbcSQLSyntaxErrorException: Table "INSTRUCTOR" not found; SQL statement:
INSERT INTO "INSTRUCTOR" ("NAME") VALUES (?) [42102-200]
是实体类:
import lombok.Data;
import org.springframework.data.annotation.Id;
import org.springframework.data.domain.Persistable;
import org.springframework.data.relational.core.mapping.Table;
@Data
@Table
public class Instructor{
@Id
private String id;
private String name;
}
控制器使用这个存储库:
import org.springframework.data.repository.CrudRepository;
import test.com.small.school.model.Instructor;
public interface InstructorRepository extends CrudRepository<Instructor, String> {
}
控制器:
@Controller
@RequestMapping("/add")
public class AddController implements Serializable {
private static final long serialVersionUID = 1L;
private final InstructorRepository instructorRepo;
@Autowired
public AddController(InstructorRepository instructorRepo) {
this.instructorRepo = instructorRepo;
}
@GetMapping("/instructor")
public String addInstructorForm(Model model) {
model.addAttribute("instructor", new Instructor());
return "instructor";
}
@PostMapping("/instructor")
public String saveInstructor(@ModelAttribute Instructor instructor, Model model) {
model.addAttribute(instructor);
instructorRepo.save(instructor);
return "iresult";
}
这是我的application.yml:
spring:
datasource:
generate-unique-name: false
name: testdb
我认为如果表丢失了，Spring数据JDBC会自动创建表，我错了吗?
这里是我得到的错误的完整长度:

Spring Data JDBC不提供自动模式生成。您需要自己编写DDL。参见https://www.baeldung.com/spring-data-jdbc-intro
您可能正在考虑Spring Data JPA，它确实提供模式生成。
