对 list 集合进行分页操作

Page<PersonalReport> reportPage = new Page<>();
reportPage.setTotal(personalReportList.size());
 //对结果进行分页操作
 if (CollectionUtil.isNotEmpty(personalReportList)) {
    
    
     int fromIndex = (page.getCurrent() - 1) * page.getSize();
     int toIndex = (page.getCurrent() - 1) * page.getSize() + page.getSize();

     //判断下标是否超过集合的大小，防止下标越界
     if (toIndex > personalReportList.size()) {
    
    
         toIndex = personalReportList.size();
     }
     reportPage.setRecords(personalReportList.subList(fromIndex, toIndex));
 } else {
    
    
     page.setRecords(personalReportList);
 }
 return reportPage;
