java后台实现简单分页

1.分页

public String selectObjects(UserVo userVo,@RequestParam(defaultValue="1")int cpage,Model model){
		//分页单位 cpage代表当前页
		int pageSize = 3;
		//总条数
		int count = userService.selectCount(userVo);
		if(count==0){
			count = 3;
		}
		//总页数
		int pageCount = count%pageSize==0?count/pageSize:count/pageSize+1;
		if(cpage>pageCount){
			cpage = pageCount;
		}
		int startIndex = (cpage-1)*pageSize;
		List<UserExtends> userList = userService.selectObjects(userVo,startIndex,pageSize);
		model.addAttribute("pageCount", pageCount);
		model.addAttribute("cpage", cpage);
		model.addAttribute("userList", userList);
		model.addAttribute("userVo", userVo);
		return "userList";
	}
