CSV ファイルを生成する Java クラスを作成しました。
public class CSVGenerator {
private static String REFERRAL_HEADER = "Position,Mail,Invitations,Qualified invitations";
private static String TOPS_HEADER = "Position,Mail,Number of conferences,Number of new contacts, Average conf duration";
public static String generate(String source, JsonNode root) throws IOException {
String result = "";
CSVWriter writer = new CSVWriter(new FileWriter(source+".csv"));
if (source.compareTo("referral") == 0)
result = REFERRAL_HEADER;
else if (source.compareTo("tops") == 0)
result = TOPS_HEADER;
writer.writeNext(result.split(","));
Iterator<JsonNode> it = root.getElements();
while (it.hasNext()) {
Iterator<JsonNode> it2 = it.next().getElements();
result = "";
while (it2.hasNext())
{
result += it2.next().asText();
if (it2.hasNext())
result += ",";
}
writer.writeNext(result.split(","));
}
writer.close();
return result;
}
}
結果のファイルは整形式ではありません。次のように、すべてのセルと区切りコンマを含む、行ごとに 1 つのセルしかありません。
header1,header2,header3
1,support,test
2,alpha,gamma
私は何を間違っていますか?
編集:
出力をより正確にするには
私は持っています: "header1、header2、header3"、""、""
私が欲しい:「header1」、「header2」、「header3」
これが私の出力です。1 つの一意のセル内の各行。
