Question

我正在构建Java Jersey 2 Rest API（爬虫）。抓取工具从文章中检索文本并在json中返回。该API稍后将被其他开发人员使用。

所以我的问题是 - 如何在json输出中的字符串中“保留”换行符？

处理此问题的另一项服务示例（json输出）：

"text": "When Etsy bought Grand St. last April, . But that’s about to change. At the end of this month, Grand St. will stop processing orders and on October 1, listings on the site will become inactive. At that point, Grand St.’s site will just be a gallery of content and photos.\nThat’s because the Grand St. team has taken on a lot more projects at Etsy, so from a user experience and maintenance perspective, it made sense to move Grand St. away from commerce, Etsy Senior PR Manager Nicole Summer told TechCrunch.\n“We at Etsy and Grand St. have truly appreciated all the hard work from Grand St. makers, and we welcome them to learn more about joining the Etsy community,” Summer said. “The Grand St. team has become an integral part of the Etsy organization, working on innovative projects to help our sellers scale. We’re grateful to have them on board and excited to continue the work we’re doing to empower our sellers to achieve their creative business goals on their own terms.”\nFor background, Grand St. sells things like solar chargers, a smart light for nighttime bike rides and The Cash Cannon for making it rain. Before the acquisition, Grand St. had raised $1.3 million in seed funding from First Round Capital, David Tisch, Gary Vaynerchuk, betaworks, Collaborative Fund, MESA+, Quotidian Ventures, and Undercurrent.\nFeatured Image: Dennis Skley/Flickr UNDER A CC BY-ND 2.0 LICENSE",

你可以看到他们在json中使用\ n。

我也在使用杰克逊并按照以下方式进行操作（此处仅粘贴特定部分）。对我来说，事情是有效的，根据你的需要改变它。

@GET
@Path("/getLocale")
@Produces({ MediaType.APPLICATION_JSON} )
public Response getLocale(@Context HttpServletRequest request) {
    ResponseBuilder responseBuilder = Response.status(200);

    String str=null;
    byte[] bytes=null;

    String appLocation = SystemParameters.getInstance().getParameter("application.home.dir")+"/WEB-INF/lang/";

    InputStream is = new FileInputStream(appLocation+"/en_US.json");

    try {
        bytes = IOUtils.toByteArray(is);
    } catch (IOException e) {
        //ERROR
    }

    str = new String(bytes, "UTF-8");
    str = str.replaceAll("\\r\\n", "");
    str = str.replaceAll("\\t", "");
    str = str.replaceAll("\\\"", "\"");

    return responseBuilder.entity(str).build();
}

JSON文件：

"CERTIFICATE_STATUS_PASSWORD_INVALID":"Unable to read certificate with the given password.\nUpload the certificate with a valid password."

在JSON中“保留”换行符的好方法？
