使用jsoup爬取了下某個網站中的《冰與火之歌》信息，并將格式保存成了json格式到文本文件中。

具體執行的代碼如下：?

public static void main(String[] args) throws IOException {TestJsoupBingYuHuo tj = new TestJsoupBingYuHuo();tj.test();}static String urlPath = "http://www.bingyuhuozhige.cc";static String srcPath = "D:\\study\\jsoup\\bingyuhuozhige\\";static boolean writeOnOff = true;public void test() throws IOException {Document document = JsoupUtils.getRoot(urlPath);Elements h3lists = document.select("h3");this.analysisH3List(h3lists);}// 解析冊信息private JSONArray analysisH3List(Elements h3List) throws IOException {int n = 0;for (Element h3 : h3List) {n++;if (n < 7) { //改變這里的數字，可以設置從第幾冊開始跑continue;}// h3 是冊名String h3Text = h3.text().trim();System.out.println(h3Text);if(writeOnOff) {FileUtils.createDir(srcPath + h3Text); // 創建冊目錄}// p 是冊的描述Element p = this.analysisPList(h3, srcPath + h3Text);// 解析冊的描述，并存儲到冊對應目錄下的文件中// div class = row 內的 links 是每個章節的首頁this.analysisFirstPageLink(p, srcPath + h3Text);}return null;}// 解析 冊的描述private Element analysisPList(Element h3, String path) {Element p = null;while (p == null || !p.tagName().equals("p")) {if (p != null) {p = p.nextElementSibling();} else {p = h3.nextElementSibling();}System.out.println("=");}String pText = p.text().trim();System.out.println(pText);if(writeOnOff) { FileUtils.writeLine(path + File.separator + "簡述", pText);}return p;}// 解析每章的首頁urlprivate JSONArray analysisFirstPageLink(Element p, String path) throws IOException {Element divRow = null;while (divRow == null || !divRow.tagName().equals("div") || !divRow.hasClass("row")) {if (divRow != null) {divRow = divRow.nextElementSibling();} else {divRow = p.nextElementSibling();}System.out.println("=");}Elements links = divRow.select("a[href]");for (Element link : links) {String url = link.attr("href").trim();String title = link.attr("title").trim();// 為每個 title 創建一個 文本title = title.startsWith("第六十一章 獅鷲的重生") ?
