java - 丢失新行符号 (\r\n)

Question

我有一个宏，它从 JIRA 获取整个问题信息(作为 JSON 对象)并将其打印在 Confluence 中。但在 Confluence 中，新行丢失，格式也乱了。

这是 Jira 中的文本(及其外观):

Reports are afterwards sent via ftp to Aviva Risk Management team.

Aviva risk team use the daily reports to extract some of the numbers and for a report on the risk performance of the portfolio.

这是它在 JSON 中的样子:

Reports are afterwards sent via ftp to Aviva Risk Management team.\r\n\r\nAviva risk team use the daily reports to extract some of the numbers and for a report on the risk performance of the portfolio.

这是之后打印的内容:

Reports are afterwards sent via ftp to Aviva Risk Management team. Aviva risk team use the daily reports to extract some of the numbers and for a report on the risk performance of the portfolio.

基本上，我从中得到的是 \n\r 符号丢失或者没有按照 Confluence 中应有的方式进行转换。我该如何解决这个问题？

编辑:@Octopus 这是代码。

public class FieldinfoMacro implements Macro {

    @Override
    @SuppressWarnings("unchecked")
    // This macro gets the issue's field values from the page's context so you don't have to
    // make new requests to Jira for each field seperately

            throws MacroExecutionException {

        // parameters

                            } else temp.append(((JSONArray) output).getString(i));
                            result = temp;
                        }

            } catch (JSONException je) {
                je.printStackTrace();
         }

        return result.toString();
    }

你不必担心这个。 JSON完全能够代表任何 UTF-8特点。收到 JSON 字符串后，您肯定会在代码中执行某些操作，从而消除 \r\n人物。您应该能够转换 \r\n到新行，例如添加 <br>通过编写你的逻辑来创建 html 标签。请在帖子中添加如何从 JSON 获取数据并将其打印在页面中

此行从字符串中删除所有“\r\n”

 result = ((String) result).replaceAll("\\W", " ");

这就是为什么字符串文字没有任何 \r和\n人物。请删除该行并进行测试。请注意\W意思是“任何非单词字符”。即排除这些 [a-zA-Z0-9_] 的字符人物。希望这有帮助
