java 调用远程接口返回的List如何分页

Question

远程访问调用接口访问数据查询出来的数据保存在List中，如何进行分页

Answer 1

自己计算分页吧；
/**

• Range *
• @author littlehow

• @time 2016-06-02 14:45
  */
  public class RangeUtils {

  /**

  • 获取分页信息
  • @param pageNo
  • @param pageSize
  • @return */ public static Range getPageRange (int pageNo, int pageSize) { Range range = new Range(); if (pageNo < 1 || pageSize < 1) return range; int start = (pageNo - 1) * pageSize + 1; int end = start + pageSize - 1; range.setEnd(end); range.setStart(start); range.setDistance(pageSize); return range; }

  public static class Range {
  private int start = 0;
  private int end = 0;
  private int distance;

  public boolean isValid() {
      return start >=0 & end > 0 & end > start;
  }
  
  public boolean outRange(int num) {
      return start > num;
  }
  
  public int getStart() {
      return start;
  }
  
  public void setStart(int start) {
      this.start = start;
  }
  
  public int getEnd() {
      return end;
  }
  
  public void setEnd(int end) {
      this.end = end;
  }
  
  public int getDistance() {
      return distance;
  }
  
  public void setDistance(int distance) {
      this.distance = distance;
  }
  

  }
  }

int end = range.getEnd();
totalCount就是你list的size；
/** 数据超出最后范围 */
if (end > totalCount) {
end = totalCount;
}
最后对list进行subList

如果有帮助，希望采纳
