前言：
而今兄弟们对“csvjava”大体比较讲究，看官们都想要剖析一些“csvjava”的相关资讯。那么小编也在网摘上网罗了一些对于“csvjava””的相关知识，希望咱们能喜欢，咱们一起来学习一下吧！Object o = datas.get(0);
String objName = o.getClass().getSimpleName();
DateFormat dateFormat = new SimpleDateFormat("yyyyMMddHHmmss");
String csvFilePath = filePath + objName + dateFormat.format(new Date()) + ".csv";
File file = new File(csvFilePath);
if (!file.exists() && !file.isDirectory()) {
file.mkdirs();
}
//构造头部数据
String[] title = ObjectTransferUtils.generateObjAttr(o);
CSVFormat csvFormat = CSVFormat.DEFAULT.withHeader(title);
OutputStreamWriter ouputStream = new OutputStreamWriter(out, "GBK");
CSVPrinter printer = new CSVPrinter(ouputStream, csvFormat);
for (int i = 0; i < datas.size(); i++) {
Object obj = datas.get(i);
String[] titl = ObjectTransferUtils.generateObjAttr(obj);
Object[] value = new Object[titl.length];
for (int t = 0; t < titl.length; t++) {
if (titl[t] == null) {
continue;
}
value[t] = ObjectTransferUtils.generateAttrValue(titl[t], obj);
}
printer.printRecord(value);
}
