分页

一、

public class PageObject {

   public PageObject(Integer page, Integer size) {

      this.page = page;

      if (page < 1) {
         page = 1;
      }
      this.pageSize = size;
   }

   public PageObject() {
      super();
   }

   // 开始索引
   private Integer page;

   // 一页行数
   private Integer pageSize;

   // 总行数
   private Integer totalCount;

   public PageObject(Integer page, Integer size, Integer totalCount) {

      this.page = page;

      if (page < 1) {
         page = 1;
      }
      this.pageSize = size;

      this.totalCount = totalCount;
   }

   @Override
   public String toString() {
      StringBuilder builder = new StringBuilder();
      builder.append("PageObject [page=").append(page).append(", pageSize=")
            .append(pageSize).append(", totalCount=").append(totalCount)
            .append("]");
      return builder.toString();
   }

   public Integer getPage() {
      return page;
   }

   public void setPage(Integer page) {
      this.page = page;
   }

   public Integer getPageSize() {
      return pageSize;
   }

   public void setPageSize(Integer pageSize) {
      this.pageSize = pageSize;
   }

   /*
    * 获取总页数
    */
   public Integer getTotalCount() {
      int count = 0;
      if (this.totalCount > 0) {
         count = this.totalCount % pageSize == 0 ? (this.totalCount / this.pageSize)
               : (this.totalCount / this.pageSize + 1);
      }
      return count;
   }

   public void setTotalCount(Integer totalCount) {
      this.totalCount = totalCount;
   }

   /*
    * 获取起始位置
    */
   public Integer getStartIndex() {
      int startIndex = (page - 1) * pageSize;
      return startIndex;
   }

   /*
    * 获取结束位置
    */
   public Integer getEndIndex() {
      int endIndex = this.page * this.pageSize;
      return endIndex;
   }
}

二、

Integer total=mobileService.getTotal();

PageObject pageObj = new PageObject();
pageObj.setTotalCount(total);
pageObj.setPageSize(synchronizeNum);
int pageNum = pageObj.getTotalCount();

for (int i=0;i<pageNum;i++){

pageObj.setPage(i);
map.put("startIndex", i*synchronizeNum);
map.put("endIndex", (i+1)*synchronizeNum);
List<Mobile> list= mobileService.list(map);

for (Mobile u:list) {

 xxxxxxxxxxxxxxxxxxx
 
}
