我在项目中同时使用Java和Kotlin,因此可能存在依赖问题,我尝试了不同的实现和kapt,但没有成功。
我的依赖项(请参见room持久性库的最后)

我的实体类
@Entity(tableName = "product")
public class Product
{
@PrimaryKey
@ColumnInfo(name = "id")
public Integer id;
@ColumnInfo(name = "category")
public String category;
@ColumnInfo(name = "name")
public String name;
@ColumnInfo(name = "price")
public Double price;
@ColumnInfo(name = "desc")
public String desc;
@ColumnInfo(name = "img_url")
public String img_url;
public Product(Integer id, String category, String name, Double price, String desc, String img_url) {
this.id = id;
this.category = category;
this.name = name;
this.price = price;
this.desc = desc;
this.img_url = img_url;
}
}
当不使用@Query时,我的Dao类构建得很好,但是当使用@Query时,会导致构建错误。
@Dao
public interface CartDao
{
@Query("SELECT * FROM product")
ArrayList<Product> getAllProduct();
@Delete
void delete(Product cart);
}
构建错误
