如何使用Spring Jdbc获取游标结果？

Question

我是新来的春天。 我正试图调用存储过程返回结果的形式游标。我试图用rowMapper甚至OracleTypes.CURSOR. 但每次我得到error.I使用Oracle数据库。我没有权利更改数据库程序，所以只有选项才能实现使用java代码。请指导我。我在哪里做错了。我尝试了所有的jdbc选项来传递参数，但无法弄清楚。

程序

create or replace PROCEDURE SELECT_DETAILS 
(IN_Logged_User_ID NUMBER) 
AS 
cursor SELECT_ALL_DATA is 
    select 
     type, 
     type_desc, 
     file_format, 
     decode(active_flg, 'Y',1,0) as active_flg, 
     to_char(modified_date, 'mm/dd/yyyy hh24miss') as modified_date 
    from documentType 
    order by doc_type; 
ERR_MSG varchar2(600); 
APP_ERROR exception; 
Err_no  NUMBER; 
BEGIN 
    IF Err_no = -1 THEN 
    RAISE APP_ERROR; 
    RETURN; 
    END IF; 

    BufferMgr.ClearBuffer; 
    BufferMgr.MaxColumns(6); 
    for dttRow in SELECT_ALL_DATA 
    loop 
     BufferMgr.PutColumn(dttRow.doc_type); 
     BufferMgr.PutColumn(dttRow.doc_type); 
     BufferMgr.PutColumn(dttRow.doc_type_desc); 
     BufferMgr.PutColumn(dttRow.def_file_format); 
     BufferMgr.PutColumn(dttRow.active_flg); 
     BufferMgr.PutColumn(dttRow.modified_date); 
     BufferMgr.NewRow; 
    end loop; 

    exception 
    when APP_ERROR then 
     Rollback; 
     BufferMgr.PutColumn('!@#$' || ERR_MSG); 
     BufferMgr.NewRow; 
     RAISE BufferMgr.app_errors_exit; 
    when others then 
     Rollback; 
     BufferMgr.PutColumn('!@#$' || TrackORAError(SQLCODE,SQLERRM)); 
     BufferMgr.NewRow; 
     RAISE BufferMgr.app_errors_exit; 
END; 

的Java

public Map<?, ?> simpleProcedureCall(String procedureName,Long loginId){ 
     SimpleJdbcCall procReader = new SimpleJdbcCall(jdbcTemplate); 
     procReader.withProcedureName(procedureName).declareParameters(new SqlOutParameter("SELECT_ALL_DATA",OracleTypes.CURSOR, new DocTypeMapper()), 
       new SqlParameter("IN_Logged_User_ID", Types.NUMERIC)); 
     SqlParameterSource inParams = new MapSqlParameterSource().addValue("IN_LOGGED_USER_ID", loginId,Types.NUMERIC); 
     Map<String, Object> simpleJdbcCallResult = procReader.execute(inParams); 
     return simpleJdbcCallResult; 
    } 

    private class DocTypeMapper implements RowMapper<DocumentType> 
    { 
     @Override 
     public DocumentType mapRow(ResultSet rs, int rowNum) throws SQLException { 

      DocumentType docTypeObject = new DocumentType(); 
      docTypeObject.setDocType(rs.getString("type")); 
      docTypeObject.setDescription("type_desc"); 
      docTypeObject.setFileFormat("file_format"); 
      docTypeObject.setIsActive("active_flg"); 
      docTypeObject.setLastModified("modified_date"); 
      return docTypeObject; 
     } 

    } 

错误。

那么，在您的Java您声明从中似乎并不在程序中声明本身存在的程序的输出参数（SELECT_ALL_DATA）。你可能会想尝试类似：

create or replace PROCEDURE SELECT_DETAILS 
    (IN_Logged_User_ID NUMBER, SELECT_ALL_DATA OUT SYS_REFCURSOR) 
    AS 
    OPEN SELECT_ALL_DATA FOR 
     select 
      type, 
      type_desc, 
      file_format, 
      decode(active_flg, 'Y',1,0) as active_flg, 
      to_char(modified_date, 'mm/dd/yyyy hh24miss') as modified_date 
     from dtt 
     order by doc_type; 
    --etc 

我不知道所有的BufferMgr的东西是什么，所以无法在部分评论...
