这是我的GetLastTrade，我想获得另一个方法的int结果 int stockdata count在这里被调用：
public StockData GetLastTrade(String UserName, String SymbolName, StockData stockData)
{
System.out.println("error in GetLastTrade " + SymbolName + "username==" + UserName + "TRANSDATE ==" + stockData.getTRANSDATE() + "OPENPRICE==" + stockData.getOPENPRICE());
try
{
System.out.println("GetLastTrade done==" + stockData.getTRANSDATE());
return stockDataService.GetLastTrade(UserName, SymbolName, stockData);
}
catch(Exception e)
{
System.out.println("stockDataService.GetLastTrade error" +e);
e.printStackTrace();
}
return stockData;
}
这是我的代码中的int countStockData：
public int countStockData(String UserName, String SymbolName, StockData stockData)
{
String transdateforquery = stockData.getTRANSDATE();
try
{
return template.queryForInt(
"SELECT COUNT(TRANSDATE) FROM stockdata WHERE transdate= ? AND symbolname = ?",
rowMapper,transdateforquery, SymbolName);
}
catch (TransientDataAccessResourceException e)
{
System.out.println("TransientDataAccessResourceExc eption====");
// TODO Auto-generated catch block
e.printStackTrace();
return 0;
}
}
IM收到此错误：

上面代码中的问题是什么，以及新代码是什么。我是新手，因此遇到问题
答案 0 :(得分：0)
我猜你的rowMapper（无论是什么，因为它没有显示）是不可序列化的。我也猜测方法调用不需要它，因为它只在语句中定义了t个变量。
仅供参考：您的命名约定遍及getTRANSDATE（），一些方法名称和变量的上限。你甚至不符合你正在使用的不良做法。
答案 1 :(得分：0)
看起来transdateforquery被定义为字符串。如果数据库列transdate被定义为日期，则这可能不起作用。尝试将transdateforquery转换为java.sql.Date并将其传递给您的查询。
