本文整理了Java中org.springframework.data.mongodb.core.query.Query.with方法的一些代码示例，展示了Query.with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。Query.with方法的具体详情如下：
包路径：org.springframework.data.mongodb.core.query.Query
类名称：Query
方法名：with

Query.with介绍

[英]Sets the given pagination information on the Query instance. Will transparently set skip and limit as well as applying the Sort instance defined with the Pageable.
[中]设置查询实例上的给定分页信息。将透明地设置skip和limit，并应用使用Pageable定义的排序实例。

代码示例

@Override
protected Query complete(Criteria criteria, Sort sort) {
  Query query = (criteria == null ? new Query() : new Query(criteria)).with(sort);
  if (LOG.isDebugEnabled()) {
    LOG.debug("Created query " + query);
  }
  return query;
}
