java-使用@Query Room Persistence Library时的org.gradle.execution.MultipleBuildFailures

在Dao类(房间持久性库)中使用@Query时出现生成错误

 

我在项目中同时使用java和kotlin,因此可能存在依赖关系问题,我尝试了不同的实现和kapt,但没有运气.

我的依赖项(有关房间持久性库的更多信息,请参见)

我的实体班

 

    @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;
        }
    }

我的Dao类在不使用@Query时构建良好,
但是使用@Query时,会导致构建错误.

 

    @Dao
    public interface CartDao
    {
        @Query("SELECT * FROM product")
        ArrayList getAllProduct();


        @Delete
        void delete(Product cart);
    }

构建错误

最佳答案

@Dao
public interface CartDao
{
    @Query("SELECT * FROM product")
    ArrayList getAllProduct();


    @Delete
    void delete(Product cart);
}

代替ArrayList使用列表
