Question

我正在尝试使用Spring引导应用程序中的PostGreSQL数据库进行全文搜索。

以下是我为全文搜索撰写的查询。

public interface ProductSubCategoryRepository extends JpaRepository<ProductSubCategory, Long>{

           @Query(name = "SELECT product_category, product_subcategory, "
            + "product_level_category, product, product_attribute "
            + "FROM public.product_category "
            + "INNER JOIN public.product_subcategory "
            + "ON (product_category.id = product_subcategory.product_category_id) "
            + "INNER JOIN public.product_level_category "
            + "ON (product_subcategory.id = product_level_category.product_sub_category_id) "
            + "INNER JOIN public.product "
            + "ON (product_level_category.id = product.product_level_category_id) "
            + "INNER JOIN product_attribute "
            + "ON (product.id = product_attribute.product_id) "
            + "WHERE to_tsvector(product.name) @@ to_tsquery(:query) "
            + "OR to_tsvector(product_attribute.name) @@ to_tsquery(:query) "
            + "OR to_tsvector(product_level_category.name) @@ to_tsquery(:query) "
            + "OR to_tsvector(product_subcategory.name) @@ to_tsquery(:query)", nativeQuery = true)
            public List<ProductSubCategory> findProductSubCategoriesByName(@Param("query") String query);
    }

但是在数据库GUI工具（pgAdmin）上运行以下查询时。它取得了一些成果。但是当我尝试这个类似的查询时，没有结果。

控制台日志显示我错误地创建了查询

查询构建不正确用于全文搜索的Spring Data JPA存储库
