我有以下代碼：@Controllerpublic class GatesController { @RequestMapping ("/gates") public static String qualityGates(String x) throws IOException { try { System.out.println("\n------QualityGates------"); URL toConnect = new URL(x); HttpURLConnection con = (HttpURLConnection) toConnect.openConnection(); System.out.println("Sending 'GET' request to URL : " + x); BufferedReader in = new BufferedReader( new InputStreamReader(con.getInputStream())); String inputLine; StringBuffer response = new StringBuffer(); while ((inputLine = in.readLine()) != null) { response.append(inputLine); } in.close(); //Cast the JSON-File to a JSONObject JSONObject res = new JSONObject(response.toString()); JSONArray gates = new JSONArray(res.getJSONObject("projectStatus").getJSONArray("conditions").toString()); JSONObject test = new JSONObject(res.getJSONObject("projectStatus").toString()); String a = ("\nThe current Project-Status is: " + test.get("status") + "\n"); String b = ""; for (int i = 0; i < gates.length(); i++) { String status = gates.getJSONObject(i).getString("status"); String metric = gates.getJSONObject(i).getString("metricKey"); b = b + ("<\b>Status: " + status + " | Metric: " + metric); } System.out.println(a+b); return a + b; } catch (Exception e) { System.out.println(e); return String.format("Error"); } }問(wèn)題是目前該網(wǎng)站如下所示：網(wǎng)站_當(dāng)前但我希望每個(gè)指標(biāo)都換行，而不是在一行中。正如您所看到的，我嘗試在字符串內(nèi)涵處添加 <\b> 您知道如何解決這個(gè)問(wèn)題嗎？這是我的第一個(gè)網(wǎng)絡(luò)應(yīng)用程序，我有點(diǎn)卡住了。我感謝每一個(gè)幫助！

你的“<\b>”打破了它。如果刪除它并添加換行符“\n”，它應(yīng)該可以工作。像這樣：
String a = ("\nThe current Project-Status is: " + test.get("status") + "\n");
String b = "";
for (int i = 0; i < gates.length(); i++) {
status = gates.getJSONObject(i).getString("status");
String metric = gates.getJSONObject(i).getString("metricKey");
b = b + ("Status: " + status + " | Metric: " + metric + "\n");
}
您還返回純文本。因此，要正確顯示它，請(qǐng)?zhí)砑印皃roducts =”text/plain”以返回格式化的字符串。
@GetMapping(value = "/gates", produces = "text/plain")
然后你的輸出將顯示換行符。這樣您就可以應(yīng)用進(jìn)一步的格式。
