本文整理了Java中javax.ws.rs.core.Request.selectVariant方法的一些代码示例，展示了Request.selectVariant的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Request.selectVariant方法的具体详情如下：
包路径：javax.ws.rs.core.Request
类名称：Request
方法名：selectVariant

Request.selectVariant介绍

[英]Select the representation variant that best matches the request. Returns null in case there is no matching variant in the list.

More explicit variants are chosen ahead of less explicit ones. A vary header is computed from the supplied list and automatically added to the response.
[中]选择与请求最匹配的表示变量。如果列表中没有匹配的变量，则返回null。
在不太明确的变体之前，选择更明确的变体。根据提供的列表计算vary头，并自动添加到响应中。

@GET
public Response content() {
  if (content.isEmpty()) {
    return Response.noContent().build();
  }

  if (variant == null) {
    return Response.notAcceptable(supportedVariants).build();
  } else {
    return Response.ok(content, variant.getMediaType()).build();
  }

MediaType.APPLICATION_XML_TYPE,
    MediaType.APPLICATION_JSON_TYPE).build();
final Variant variant = request.get().selectVariant(variants);
