java JDBC 批量插入的時候報數組下標越界，求大神

代碼：
private static Boolean Function_User(Map resultMap, String sql,String tableType) {
// TODO Auto-generated method stub

    Connection conn=null;
    PreparedStatement insert_st=null;
    int count = 0;
    final int batchSize = 500;
    System.out.println("開始："+Calendar.getInstance().getTime());
    try {
        conn=DriverManager.getConnection(db_url,db_name,db_pwd);
        conn.setAutoCommit(false);
        insert_st = conn.prepareStatement(sql);
        for (int i = 0; i < resultMap.get(tableType).size(); i++) {
            Object obj = resultMap.get(tableType).get(i);               
            OrderUserSnap user = (OrderUserSnap) obj;
            insert_st.setString(1, ZH_S(user.getId()));
            insert_st.addBatch();

             if(++count % batchSize == 0) {
                 insert_st.executeBatch();
                 insert_st.clearBatch();
                }
             System.out.println("tt:"+count);
        }
        insert_st.executeBatch();
        insert_st.clearBatch();
    } catch (SQLException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }finally{
        try {
            insert_st.close();
            conn.close();
             System.out.println("結束："+Calendar.getInstance().getTime());
        } catch (SQLException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }       
    }
    return true;
}

最佳回答：

擦 已經解決：原因是 我insert_st.setString(1, ZH_S(user.getId()));，傳遞的參數過多，Oracle的批處理個數限制為：
count=傳參個數 * 查入的數據條數

上邊設置的1000條數據，進行一次批處理，越界了~
將 final int batchSize = 500; 的值設小一點就屁事沒有
