1.效果将系统总人数统计显示到大屏 1. 使用dv-digital-flop组件 dv-digital-flop :configconfig1 stylewidth:100%;height:100%; /
number中的元素将被用于替换content内容模版中的{nt}标记其替换顺序与模版标记的顺序一一对应 config1: { number: [], content: {nt}, style: { ...style, fill: #00fdfa, }, }
2. 获取数据并显示 //统计人数 countUsers().then(res { if (!this.timer) { console.log(统计人数, res); } if (res.code 200) { this.countUsers res.countUsers; this.config1 { ...this.config1, number: [this.countUsers] } } })
3. 使用定时器轮询刷新 //轮询 switper() { if (this.timer) { return } let looper (a) { this.getData() }; this.timer setInterval(looper, this.$store.state.settings.echartsAutoTime); }
其中this.$store.state.settings.echartsAutoTime可替换成3000
4. user.js增加api
// 查询用户数
export function countUsers() {return request({url: /system/user/countUsers,method: get})
}
5. 增加controller后端方法
/*** 获取用户数*/GetMapping(/countUsers)
public AjaxResult countUsers()
{AjaxResult ajax AjaxResult.success();Integer count userService.countUsers();ajax.put(countUsers, count);return ajax;
}
6. mapper.xml
select idcountUsers resultTypeIntegerselect count(1) from sys_user where del_flag0
/select7. 最终代码
