jsp手动分页

注意：

sql语句要写对，jsp显示 List 时的 item的字段名要写对

这里 where uid 要放在前面才能成功执行，否则会报错

SELECT * FROM conn_logs WHERE uid = 0 ORDER BY gid DESC LIMIT 0,15

在写items的时候，如果controller里面已经写了，这里会有提示

成功效果：

分页：

1. 注意顺序

2. start = Integer.parseInt(request.getParameter("start")); // 这里是得到参数的值，不是getsession哦，之前就错在这里

@Controller
public class ConnLogsController {

    @Autowired
    HttpServletRequest request;

    @RequestMapping("showConnLogs")
    public ModelAndView showConnLogs() {
        ModelAndView modelAndView = new ModelAndView();
        RepoDao repoDao = new RepoDaoImp();
        int start = 0;
        int count = 10;

        try {
            start = Integer.parseInt(request.getParameter("start"));
        } catch (Exception e) {
        }

        int next = start + count;

        int userId = (int) request.getSession().getAttribute("userId");

        List<ConnLogs> connLogs = repoDao.showPage(userId, start, count);
        modelAndView.addObject("next", next);
        modelAndView.addObject("connLogs", connLogs);

        modelAndView.setViewName("/jsp/ConnLogs/ConnLogsViewer.jsp");
        return modelAndView;

    }
}
