mysql - Spring StoredProcedure Object 返回对象列表

Question

我使用 mysql 存储过程来检索对象列表。这可能吗 ？

我在关注这篇文章

问题：

1. 如何使用结果集在 select 语句中检索对象列表？

2. 如何将结果集映射到对象列表？

   CREATE DEFINER= root@ localhostPROCEDURE generateLCRReport(IN countryCodeParamINT, OUT countryCodeINT, OUT dialCodeINT, OUT custPrefixVARCHAR(50), OUT vendorPrefixVARCHAR(50), OUT custPriceFLOAT, OUT vendorCostFLOAT, OUT profitFLOAT) 语言 SQL 确定性读取 SQL 数据 SQL 安全定义器注释“generateLCRReport”开始选择 c.country_code 作为 countryCode，c.dial_code 作为 dialCode，c.customer_prefix 作为 custPrefix，c.vendor_prefix 作为 vendorPrefix，max(cust_rate.rate) 作为 custPrice，min(ven_rate.rate) 作为 vendorCost，round(max(cust_rate.rate) ) - min(ven_rate.rate), 3) 作为 cdr c 的利润

   inner join (select a.id, r.rate, re.country_code, re.dial_code, ap.prefix from rate r inner join region re on r.region_id = re.id inner join account_prefix ap on r.account_prefix_id = ap.id a.id = ap.account_id 上的内部加入帐户 a，其中 ap.prefix_type = 0 ）作为 cust_rate

   在 c.country_code = cust_rate.country_code 和 c.dial_code = cust_rate.dial_code 和 c.customer_prefix = cust_rate.prefix 和 c.customer_id = cust_rate.id

   inner join (select a.id, r.rate, re.country_code, re.dial_code, ap.prefix from rate r inner join region re on r.region_id = re.id inner join account_prefix ap on r.account_prefix_id = ap.id内部加入帐户 a on a.id = ap.account_id where ap.prefix_type = 1 ) as ven_rate

   在 c.country_code = ven_rate.country_code 和 c.dial_code = ven_rate.dial_code 和 c.vendor_prefix = ven_rate.prefix 和 c.vendor_id = ven_rate.id 其中 c.country_code = countryCodeParam 组由 c.country_code 和 c.dial_code 顺序由 c .country_code 升序限制 5000；

       SqlOutParameter outParam4 = new SqlOutParameter("custPrice", Types.FLOAT);
       SqlOutParameter outParam5 = new SqlOutParameter("vendorCost", Types.FLOAT);
       SqlOutParameter outParam6 = new SqlOutParameter("profit", Types.FLOAT);
   
       this.declareParameter(rs);
       this.declareParameter(outParam);
       this.declareParameter(outParam1);
       this.declareParameter(outParam2);
       this.declareParameter(outParam3);
       this.declareParameter(outParam4);
       this.declareParameter(outParam5);
       this.declareParameter(outParam6);
   
       this.setFunction(false);
       this.compile();
   }
   
   /**
    * @param countryCode
    * @return

   public Map<String, ?> generateLCRReport(int countryCode) {
   
       Map<String, Object> inParam = new HashMap<String, Object>();
   
       inParam.put("countryCodeParam", new Integer(countryCode));
   
       return this.execute(inParam);
   }
   

   }

请帮忙。

谢谢。

我正在使用 RowMapper 并声明参数 SqlReturnResultSet。
