StringBuffer buf = new StringBuffer();    if (!forObject) {     buf.append("select count(*) ");    }    buf.append("from Agent agent where 1=1 ");             String gradeId = (String)conditions.get("gradeId");             if(gradeId != null && !gradeId.equals("") && gradeId != ""){              buf.append(" and agent.gradeId=").append(gradeId);             }                    buf.append(" and agent.agentId in (:agentIds) ");    Query query = sess.createQuery(buf.toString());        List ids = CommisionInfoDelegateExt.findAgentIdList(conditions);    System.out.println("ids.length=" + ids.size());
     query.setParameterList("agentIds",      ids); 当ids长度为0(空记录)时,query.list()出错.没办法,现在在ids.add("-1"),塞入一条绝对不存在的记录id(绝对是不可能的).
