springboot mybatis pagehelper 分页问题

Posted 2021-01-15 YSHY

1：添加依赖

compile group: ‘com.github.pagehelper‘, name: ‘pagehelper-spring-boot-starter‘, version: ‘1.2.9‘
注意：在spring-boot中一定要使用 pagehelper-spring-boot-starter而不是pagehelper，否则分页不起作用。

2：应用案例

@RequestMapping(
            value = "/page",
            method = RequestMethod.GET
    )
    public ResultVo getUserPages(@RequestParam Integer pageNum, @RequestParam Integer pageSize){
        PageHelper.startPage(pageNum, pageSize);//一定要在userMapper.getUsers()之前执行
        List<UserVo> list = userMapper.getUsers();
        PageInfo<UserVo> pageInfo = new PageInfo<>(list,pageSize);

        return ResultUtil.dealPageResult(pageInfo, "用户分页信息");
    }
