推荐答案

要压缩你的字符串你可以使用：

To compress your String you can use:

public static String compress(String str) throws IOException {
    if (str == null || str.length() == 0) {
        return str;
    }
    ByteArrayOutputStream out = new ByteArrayOutputStream();
    GZIPOutputStream gzip = new GZIPOutputStream(out);
    gzip.write(str.getBytes());
    gzip.close();
    String outStr = out.toString("UTF-8");
    return outStr;
 }

GZIPOutputStream来自java.util.zip

GZIPOutputStream is from java.util.zip

大多数浏览器应该能够处理gzip压缩内容而无需手动解压缩。

Most browsers should be able to handle gzip compressed content without the need of manual decompression.

文档： GZIPOutputStream

如果您使用的是Ajax，请参阅使用AJAX加载GZIP JSON文件客户端的数据采集。有必要将响应的标题设置为 @hgoebl 。

See Loading GZIP JSON file using AJAX if you're using Ajax for the data acquisition on the client-side. It is necessary to set the headers for your response as @hgoebl mentioned.
