To compress your String you can use:
要压缩您的字符串，您可以使用：
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 is from java.util.zip
GZIPOutputStream 来自 java.util.zip
Most browsers should be able to handle gzip compressed content without the need of manual decompression.
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。

如果您使用 Ajax 在客户端获取数据，请参阅使用 AJAX 加载 GZIP JSON 文件。@hgoebl如上所述，有必要为您的响应设置标头。
