string格式轉化出錯，求高手指導

代碼如下：
public class TEST implements Extractable {

   private String getSqlStr() {

          StringBuffer buf = new StringBuffer();
          buf.append("  SELECT nvl(ROUND(J.AMOUNT),’0’) AS SHIHARAIKIN1, ");

          buf.append("    FROM T_WL_TAX_PRINCIPAL  J ");

          return buf.toString();
   }

   private List<Map> execQuery() {

          PreparedStatement ps = null;
          ResultSet rs = null;
          DBean db = new DBean();
          List<Map> resultList = new LinkedList<Map>();
          Connection con = null;
          try {
                 db.connect();
                 con = db.getConnection();
                 ps = con.prepareStatement(getSqlStr());
                 rs = ps.executeQuery();
                 int i = 0;
                 while (rs.next()) {
                        Map<String, String> mapData = new HashMap<String, String>();
                 int ShiHaRaiKin = Integer.valueOf(rs.get("SHIHARAIKIN1"));
          }
                 }
          } catch (Exception e) {

                 resultList.add(mapData);
          } finally {
                 DBean.closeAll(null, ps, db);
          }
          return resultList;
   }

}

在 int ShiHaRaiKin = Integer.valueOf(rs.get("SHIHARAIKIN1")); 語句的時候報出下面錯誤：
For input string at java.lang.NumberFormatException.forInputString(Unknown Source)

我試過在rs.get("SHIHARAIKIN1")後面加個trim方法，還是會出這個錯誤，求高手指導~~~~~~~~

最佳回答：

你的select語句中“SHIHARAIKIN1,”為什麼要有個","號啊？
