我配置了弹性搜索、Kibana 和日志存储集群。弹性搜索工作正常，但 Kibana 显示错误，指出 Kibana 服务器未就绪。

日志显示

我正在尝试创建一个仪表板结构，通过单击按钮重定向到不同的组件。

我可以更改 URL，但如果没有对该 url 进行硬重新加载，页面仍然无法加载。

我的代码如下： Navigate.JS

import React from 'react';
import {
    BrowserRouter as Router,
    Switch,
    Route,
} from "react-router-dom";
import SalesDashBoard from "./salesDashBoard";
import OrderScreen from "./OrderScreen";


function SDNavigator(){
    return(
        <div>
            <Router>
                <Switch>
                    <Route exact path="/salesDesk" component={SalesDashBoard}/>
                    <Route exact path="/salesDesk/OrderScreen" component={OrderScreen}/>
                </Switch>
            </Router>
        </div>
    )}
export default SDNavigator;

SalesDashBoard.js

import React from 'react';
import {BrowserRouter as Router, Link} from "react-router-dom";
import Button from "@material-ui/core/Button";

function SalesDashBoard() {
    return (
        <Router>
            <div>
                <h3>Dashboard Links</h3>
                    <Button
                        component={Link} to="/salesDesk/OrderScreen"
                        variant="contained"

我正在使用 SQL 查询来获取数据并将列名和值映射到一个元组，然后将一组元组映射到一个映射列表，我需要跳过大小为 0 的映射，只获取带有值的映射。

我的代码和结果如下。

SELECT orbkn_surgery_procedures_order_status,orbkn_surgery_procedures_id,orbkn_surgery_procedures_or_booking,orbkn_surgery_procedures_created_date_time,orbkn_surgery_procedures_order_id FROM OR_Cube_for_surgery

    try {
  NamedDB(Symbol(db)) readOnly { implicit session =>

      Right(

        SQL(sql + " LIMIT 50000")
          .map(_.toMap())
          .list
          .apply()
      )
  }

我得到的结果集

Right(List(Map(), Map(orbkn_surgery_procedures_id -> 41, orbkn_surgery_procedures_or_booking -> 734, orbkn_surgery_procedures_order_id -> 105610),Map(orbkn_surgery_procedures_order_status -> OPD, orbkn_surgery_procedures_id -> 174, orbkn_surgery_procedures_or_booking -> 883, orbkn_surgery_procedures_order_id -> 100788), Map(orbkn_surgery_procedures_order_status -> IPD, orbkn_surgery_procedures_id -> 175, orbkn_surgery_procedures_or_booking -> 884, orbkn_surgery_procedures_order_id -> 106321), Map(orbkn_surgery_procedures_order_status -> IPD, orbkn_surgery_procedures_id -> 176, orbkn_surgery_procedures_or_booking -> 886, orbkn_surgery_procedures_order_id -> 106354),Map(), Map(), Map(), Map(), Map(), Map(), …
