[英]Spring Boot & Postgres: relation "sub_comment" does not exist
[英]Column does not exist in spring boot Postgres app
嗨,在我的Spring Boot Postgresql應用程序中,當我使用DAO檢索所有記錄時,顯示列不存在。
錯誤
WARN : org.hibernate.engine.jdbc.spi.SqlExceptionHelper - SQL Error: 0, SQLState: 42703
ERROR: org.hibernate.engine.jdbc.spi.SqlExceptionHelper - ERROR: column merchantit0_.id does not exist

實體域
@Entity
@Table(name = "merchant_item_category")
public class MerchantItemCategory{
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "id", nullable = false, length = 11)
private long id;
@ManyToOne
@JoinColumn(name = "merchant_id", nullable = false)
private Merchant merchant;
// getters and setters
}
道
public List<MerchantItemCategory> getAllMerchantItemCategoryByMerchantId(long id) {
Session session=getSession();
List<MerchantItemCategory>itemCategories=session.createQuery("from MerchantItemCategory where merchant.id=:merchantId and isDelete='0' order by categoryName asc")
.setParameter("merchantId", id)
.list();
return itemCategories;
}
我只是檢查了每個對象,它是正確的,但是該錯誤如何發生..!
導致此錯誤的潛在原因是尚未定義休眠的“默認架構”屬性。
我通過在我的application.properties中添加以下行來解決此問題:
spring.jpa.properties.hibernate.default_schema=${your-default-schema-name}
