篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了过程或函数'search_words1'期望参数'@result'，未提供相关的知识，希望对你有一定的参考价值。

我正在尝试从Java Spring Boot调用过程。我将数组作为参数传递给过程，并从过程中将列表作为结果集返回给java。请让我知道我在这里做错了什么。下面是代码：

这是我在其中提供了程序详细信息的实体类

@Entity
@Table(name="article")
@NamedStoredProcedureQuery(
        name = "search_words", 
        procedureName = "dbo.search_words1", 
        parameters = { 
            @StoredProcedureParameter(
                mode = ParameterMode.IN, 
                name = "list", 
                type = Array.class),
            @StoredProcedureParameter(
                mode = ParameterMode.OUT, 
                name = "result", 
                type = Array.class) 
            }
)
public class Article {
//entity class
}

这是我尝试调用透视图的存储库类

//Repository class
@Repository
public interface ArticleRepository extends JpaRepository<Article, Long> {

    public List<Article> findAllByOrderByArticleIdDesc();

    public List<Article> findAllByNavigationOrderByArticleIdDesc(Navigation navigation);

    @Query(nativeQuery = true, value = "exec search_words1")
    public List<Article> find(@Param("list") String[] list);
}

这是在SQL Server中创建的实际过程

    CREATE or ALTER PROCEDURE search_words1 
    @list word_list READONLY,
    @result varchar OUTPUT
AS
BEGIN
SET NOCOUNT ON
    --DECLARE @list as word_list
DECLARE @list_count int;
DECLARE @_count int;
DECLARE @qry varchar(1000);
DECLARE @wording varchar(1000);
set @_count = 0;
--print @list;
--insert into @list values (1,'java');
--insert into @list values (2,'aws');
--insert into @list values (3,'avl');
set @list_count =  (select count(*) from @list)
set @qry = ''
WHILE ( @_count < @list_count )
    BEGIN
    set @_count = @_count + 1;
    set @wording = (select word from @list where id = @_count);
    set @qry = @qry + ' SELECT * FROM article a WHERE LOWER(a.description) like ' + '''%'+@wording+'%'''
    if (@_count <> @list_count)
        set @qry = @qry + ' UNION '
    END;
    EXEC (@qry)
    set @result = @qry
--EXEC dbo.search @list
RETURN @result
END
GO

执行代码时出现以下错误：

答案

在ArticleRepository的find方法上使用@Procedure。还请确保@Procedure中的名称属性与实体中@NamedStoredProcedureQuery中提供的名称属性值匹配。
