写文件之正常写
协议布局模板
使用内置的布局文件： rdf-file-core-2.2.10.jar!/META-INF/rdf-file/protocol/fund.xml
数据定义模板
{"head":["identity|信息标识|[8,0]|default:OFDCFDAT","version|协议版本号|[4,0]|default:20","msgCreator|信息创建人|[9,0]|default:H0","msgRecipient|信息接收人|[9,0]","sendDate|传送发生日期|[8,0]|Date:yyyyMMdd","summaryTableNo|汇总表号|[3,0]","fileTypeCode|文件类型代码 |[2,0]","sender|发送人|[8,0]|default:H0","recipient|接收人|[8,0]"],"body":["TransactionCfmDate|对帐日期|[8,0]|Date:yyyyMMdd","FundCode|基金代码|[8,0]","AvailableVol|基金可用份数|Integer|[6,2]"],"tail":["fileEnd|数据文件尾部字符|default:OFDCFEND|[8,0]"],"protocol":"FUND"
}
示例程序
String filePath = new File("/Users/mengday/Temp", "demofund.txt").getAbsolutePath();
FileConfig fileConfig = new FileConfig(filePath, "templates/demofund.json", new StorageConfig("nas"));
FileWriter fileWriter = FileFactory.createWriter(fileConfig);
try {//构建文件头Map<String, Object> head = new HashMap<>();head.put("msgRecipient", "xxx");head.put("sendDate", "20231122");head.put("summaryTableNo", "aa");head.put("fileTypeCode", "bb");head.put("recipient", "ll");head.put("totalCount", 1);fileWriter.writeHead(head);// 文件数据内容Map<String, Object> row = new HashMap<>();row.put("TransactionCfmDate", "20231122");row.put("FundCode", "中国1");row.put("AvailableVol", 42.11);fileWriter.writeRow(row);// 文件尾，没有数据，是取了数据定义模板中默认值fileWriter.writeTail(new HashMap<String, Object>());

写文件之汇总写
协议布局模板
rdf-file-core-2.2.10.jar!/META-INF/rdf-file/protocol/sp.xml
数据定义模板
tail：定义字段，summaryColumnPairs：定义对什么字段进行汇总，汇总的值赋给tail的什么字段上。"totalAmount|amount"表示对totalAmount=sum(amount)，totalCount是系统预定义好的总条数。
{"head": ["fileStart|数据文件头部字符|default:汇总文件测试"],"body": ["seq|流水号","instSeq|基金公司订单号|Required","gmtApply|订单申请时间|Date:yyyy-MM-dd HH:mm:ss","date|普通日期|Date:yyyyMMdd","dateTime|普通日期时间|Date:yyyyMMdd HH:mm:ss","applyNumber|普通数字|Long","amount|金额|BigDecimal","age|年龄|Integer","longN|长整型|Long","bol|布尔值|Boolean","memo|备注"],"tail": ["totalCount|总笔数|Required|Integer","totalAmount|总金额|BigDecimal|Required"],"protocol": "SP","lineBreak": "\r\n","summaryColumnPairs": ["totalAmount|amount"]
