Spring JPA：在此ResultSet中找不到列名**

标签： spring postgresql hibernate spring-boot spring-data-jpa

我使用spring-boot，spring-jpa和postgresql数据库编写程序。我有使用crud存储库向db添加新记录的问题。我在这里重新创建我的问题是简单的程序。如果我删除此行：spring.jpa.properties.hibernate.globally_quoted_identifiers=true 我的程序运行正常但在我的真实程序中我需要这个。怎么了？

如果需要，我也可以添加pom.xml文件的内容。

人：

@Entity
public class Person implements Serializable {
    private static final long serialVersionUID = 1L;
    @Id
    @GeneratedValue(strategy=GenerationType.IDENTITY)
    private Integer id;

    private String name;
    private String lastname;

    protected Person() {}

    public Person(String name, String lastname) {
        this.name = name;
        this.lastname = lastname;
    } 
}

PersonRepository：

public interface PersonRepository extends CrudRepository<Person, Long> {
    List<Person> findByLastname(String lastname);
}

TestApplication：

@SpringBootApplication
public class TestApplication implements CommandLineRunner {

    @Autowired
    PersonRepository repository;

    public static void main(String[] args) {
        SpringApplication.run(TestApplication.class, args);
    }
    @Override
    public void run(String... strings) throws Exception {
        repository.save(new Person("Jonh", "Smith"));
    }
}

application.properties：

spring.jpa.database=POSTGRESQL
spring.datasource.platform=postgres
spring.jpa.hibernate.ddl-auto=create-drop
spring.jpa.properties.hibernate.globally_quoted_identifiers=true
spring.datasource.driver-class-name=org.postgresql.Driver
spring.datasource.url=jdbc:postgresql://localhost:5432/test
spring.datasource.username=postgres
spring.datasource.password=*********
