一:文件内容

总笔数:100|总金额:300.03
流水号|基金公司订单号|订单申请时间|普通日期|普通日期时间|普通数字|金额|年龄|长整型|布尔值|备注
seq_0|inst_seq_0|2013-11-09 12:34:56|20131109|20131112 12:23:34|23.33|10.22|22|12345|true|备注1
seq_1|inst_seq_1|2013-11-10 15:56:12|20131110|20131113 12:33:34|23.34|11.88|33|56789|false|
OFDCFEND|20131109|100

二:数据定义模板

{
 	"head":[
	     "totalCount|总笔数|Required|Long",
	     "totalAmount|总金额|BigDecimal|Required"
 	],
 	"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|BigDecimal",
	     "amount|金额|BigDecimal",
	     "age|年龄|Integer",
	     "longN|长整型|Long",
	     "bol|布尔值|Boolean",
	     "memo|备注"
    ],
    "tail": [
    	"fileEnd|数据文件尾部字符",
    	"date|普通日期|Date:yyyyMMdd",
    	"amount|金额|BigDecimal"
    ],
    "protocol":"DE"
}

协议布局模板

DE组件内置协议

示例代码

1.读取数据都会转成 HashMap实例
2.HashMap的key是数据定义模板中key

FileConfig config = new FileConfig(“文件路径”, "数据定义模板路径", new StorageConfig("nas"));
FileReader fileReader = FileFactory.createReader(config);
try {    
      Map<String, Object> tail = fileReader.readTail(HashMap.class);
      Map<String, Object> head = fileReader.readHead(HashMap.class);
      Map<String, Object> row = null;
      while (null != (row = fileReader.readRow(HashMap.class)) {
        // 处理业务
      }
} finally {
    fileReader.close();
}
