jsp页面里写方法

只需向下面那样使用即可(<%! public String paramToString(){...}%>)

<%
	String serviceCode=paramToString(request,"serviceCode");//服务编码
	if(serviceCode!=null&&!serviceCode.trim().equals("")){
		//组合对象，需要发送的消息
		//serviceCode="SC00010300";
		//String orgCode="0200";//机构号
		//String frontOperator="0000000055";//柜员号
		//String serialNumber="Flow0101";//前台流水号
		String orgCode=paramToString(request,"orgCode");//机构号
		String frontOperator=paramToString(request,"frontOperator");//柜员号
		String serialNumber=paramToString(request,"serialNumber");//前台流水号
		
		MessageQueryBean msgQueryBean = new MessageQueryBean();
		msgQueryBean.setFrontOperator(frontOperator); 
		//String outType="notice";//输出类型
		//msgQueryBean.setMsgType(outType);
		msgQueryBean.setSerialNumber(serialNumber);
		msgQueryBean.setOrgCode(orgCode);
		msgQueryBean.setServiceCode(serviceCode);
		
		//把参数值加入到map中，后台会进行校检（根据map的key值与数据库中的keyname字段的值进行检查）
		Map dataMap=new HashMap();		
		//String keyName="senarioNo";
		//String keyValue="SC00010301";
		String keyName=paramToString(request,"keyName");
		String keyValue=paramToString(request,"keyValue");
		
		dataMap.put(keyName,keyValue);
		MessageManagerServiceImpl message=new MessageManagerServiceImpl();	
		message.sendMessage(msgQueryBean, dataMap, new String[]{MsgConstants.MESSAGE_OUTTYPE_NOTICE+"="+MsgConstants.MESSAGE_MSGTYPE_CANCELACCOUNT+";",MsgConstants.MESSAGE_OUTTYPE_PRINT+"="+MsgConstants.MESSAGE_MSGTYPE_FRONTBUSINESS,MsgConstants.MESSAGE_OUTTYPE_MIDDLEDATA+"="+MsgConstants.MESSAGE_MSGTYPE_FRONTBUSINESS});
	}
