使用mybatis-plus基于BaseMapper的Page对象按条件分页查询

controller层

    /**
     * 分页列表查询
     *
     * @param role
     * @param pageNo
     * @param pageSize
     * @param req
     * @return
     */
    @RequestMapping(value = "/list", method = RequestMethod.POST)
    public ApiResult queryPageList(@RequestBody SysRoleVo sysRoleVo) {
        return service.queryPageList(sysRoleVo);
    }

service层  带有模糊查询

 /*
    分页查询
     */
    public ApiResult queryPageList(SysRoleVo sysRoleVo) {
        try {
            QueryWrapper<SysRole> queryWrapper = new QueryWrapper<>();
            queryWrapper.like("role_name", sysRoleVo.getRoleName());
            Page<SysRole> page = new Page<SysRole>(sysRoleVo.getPage(), sysRoleVo.getPageSize());
            IPage<SysRole> pageList = baseMapper.selectPage(page, queryWrapper);
            return ApiResult.success(pageList);
        } catch (Exception e) {
            log.error("查询失败", e);
            return ApiResult.fail("操作失败");
        }
    }
