本篇讲解一下 如何在Vue 中使用 Echarts + 百度地图 统计 博客访问量 并且通过QQWry 解析 ip 地址 利用Echarts 展示出来
效果图如下：
1.纯真Ip地址库 QQWry
这是我在github上找的 java版本的 解析 qqwry的
1.1 maven 引入 qqwry
<dependency> <groupId>com.github.jarodgroupId> <artifactId>qqwry-javaartifactId> <version>0.7.0version> dependency>引入后可以看到 该jar 包其实内部已经引入了 qqwry.dat 库了
使用教程：
QQWry qqwry = new QQWry(); // load qqwry.dat from classpathQQWry qqwry = new QQWry(Paths.get("path/to/qqwry.dat")); // load qqwry.dat from java.nio.file.Pathbyte[] data = Files.readAllBytes(Paths.get("path/to/qqwry.dat"));QQWry qqwry = new QQWry(data); // create QQWry with provided dataString myIP = "127.0.0.1";IPZone ipzone = qqwry.findIP(myIP);System.out.printf("%s, %s", ipzone.getMainInfo(), ipzone.getSubInfo()); // 江苏省无锡市, 电信// IANA, 保留地址用于本地回送1.2 QQWryUtils
用于提供 一个静态的 QQWry 加载 qqwry.dat ，并且提供根据ip 获取 IpZone
public class QQWryUtils { private static QQWry qqWry; static { try { qqWry = new QQWry(); } catch (IOException e) { e.printStackTrace(); } } public static IPZone getIpZoneByIp(String ip) { return qqWry.findIP(ip); }}2.提供拦截器解析Ip并放入队列
给SpringMVC 提供一个拦截器，在拦截器中 用于获取当前的请求ip 并且通过 QQWryUtils 解析该ip ，封装成IpAccessInfo 对象 存入 linkedBlockingQueue 队列中去，这里只是简单处理下
@Slf4jpublic class AccessRecordInterceptor extends HandlerInterceptorAdapter { /** * 目前是 解析 ip 并且生成 IpAccessInfo 放入 linkedBlockingQueue 队列中去 * * @param request * @param response * @param handler * @return * @throws Exception */ @Override public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception { String ip = IpUtil.getIpAddress(request); log.info("【请求者 ip : {} 】", ip); IPZone ipZone = QQWryUtils.getIpZoneByIp(ip); log.info("【解析到 城市: {}】", ipZone.getMainInfo()); IpAccessInfo ipAccessInfo = new IpAccessInfo(); ipAccessInfo.setCity(ipZone.getMainInfo()); ipAccessInfo.setIp(ip); ipAccessInfo.setOperators(ipZone.getSubInfo()); try { IpQueue.linkedBlockingQueue.add(ipAccessInfo); //这里使用 add方法 当添队列满的时候 直接捕获异常 } catch (IllegalStateException e) { log.warn("队列已满 "); } return true; }}IpAccessInfo 我这里入库ip 信息
@Data@Entity@EntityListeners(AuditingEntityListener.class)public class IpAccessInfo { @Id @GeneratedValue(strategy = GenerationType.IDENTITY) private Long id; private String ip; private String city; /** * 运营商 */ private String operators;}3.提供线程消费队列，并且根据城市记录访问量
这里提供 线程消费 队列 并且使用redis的自增 记录每个城市的访问量，并且使用SpringBoot的 CommandLineRunner 接口，在项目启动的时候 加载初始数据
/** * @author johnny * @create 2020-08-15 下午1:56 **/@Component@Order(value = 1)@Slf4jpublic class IpQueue implements CommandLineRunner { public static final LinkedBlockingQueue<IpAccessInfo> linkedBlockingQueue = new LinkedBlockingQueue(10000); @Autowired private ThreadPoolTaskExecutor threadPoolTaskExecutor; @Autowired private IpAccessInfoRepository ipAccessInfoRepository; @Autowired private IpAccessCountRepository ipAccessCountRepository; @Autowired private StringRedisTemplate redisTemplate; @Override public void run(String... args) throws Exception { //SpringBoot CommandLineRunner 接口启动后 该方法会被调用， 进行初始化数据，并且启动线程监听队列 ipAccessCountRepository.findAll().forEach(ipAccessCount -> { if (!redisTemplate.hasKey(ipAccessCount.getCity())) { redisTemplate.opsForValue().set(ipAccessCount.getCity(), String.valueOf(ipAccessCount.getCount())); } else { log.info("【Redis 存在：{} 】", ipAccessCount.getCity()); } }); log.info("【服务启动 -------------- 监听 队列 IpQueue 】"); IpAccessThread ipAccessThread = new IpAccessThread(linkedBlockingQueue, ipAccessInfoRepository, redisTemplate); threadPoolTaskExecutor.submit(ipAccessThread); //使用线程池 提交任务 } static class IpAccessThread implements Runnable { private LinkedBlockingQueue<IpAccessInfo> linkedBlockingQueue; private IpAccessInfoRepository ipAccessInfoRepository; private RedisTemplate redisTemplate; public IpAccessThread(LinkedBlockingQueue<IpAccessInfo> linkedBlockingQueue, IpAccessInfoRepository ipAccessInfoRepository, RedisTemplate redisTemplate) { this.linkedBlockingQueue = linkedBlockingQueue; this.ipAccessInfoRepository = ipAccessInfoRepository; this.redisTemplate = redisTemplate; } @Override public void run() { while (true) { try { System.out.println("开始获取 : "); IpAccessInfo accessInfo = linkedBlockingQueue.take(); System.out.println("监听到 : " + accessInfo); //江苏省无锡市 if (accessInfo.getCity().contains("省") && accessInfo.getCity().contains("市")) { String city = accessInfo.getCity(); city = city.substring(city.indexOf("省") + 1, city.indexOf("市")); if (redisTemplate.hasKey(city)) { redisTemplate.opsForValue().increment(city); //根据城市 key 进行自增 } } else { log.error("【异常 地理位置 {} 】", accessInfo.getCity()); } ipAccessInfoRepository.save(accessInfo); } catch (InterruptedException e) { e.printStackTrace(); } } } }}4. Echarts + 百度地图
由于本博客前端是用Vue 编写的，所以下面的引入就是在Vue下引入的方式
4.1 在public/index.html中添加以下代码
ak密钥：就是百度地图AK密钥，需要自己去百度地图申请，或者网上找可用的ak
53oVIOgmSIejwV7EfphPgTynOZbIiVYu 网上找的可用的密钥
<script type="text/javascript" src="http://api.map.baidu.com/api?v=2.0&ak=你的密钥"></script>4.2 在vue.config.js中添加配置
主要是 externals 部分
module.exports = {publicPath: './',outputDir: 'dist',assetsDir: 'static',indexPath: 'index.html',productionSourceMap: false, configureWebpack: { // provide the app's title in webpack's name field, so that // it can be accessed in index.html to inject the correct title. name: name, resolve: { alias: { '@': resolve('src') } }, externals: { 'BMap': 'BMap', 'BMap_Symbol_SHAPE_POINT':'BMap_Symbol_SHAPE_POINT' } },}4.3 最后在vue main.js 文件中引入
import BMap from 'BMaprequire('echarts/extension/bmap/bmap')
4.4 编写展示Echarts+百度地图的组件
可以参考echarts 网站https://echarts.apache.org/zh/index.html
需要注意 我这里是从后台拿的数据 ，是通过上面拦截器解析ip 后 记录每个城市对应的访问量存入 redis中的。
注意如果需要扩展其他城市，可以找到城市的经纬度，然后扩展 geoCoordMap 就行了。。

本篇主要记录一下 关于如何统计网站访问量，并且利用Echarts + 百度地图 友好的展示出来
1.提供拦截器 拦截Ip 请求，获取到 对应的 城市 我这里使用 纯真qqwry，网上也有其他方法。。
2.解析后 可以根据 key = 城市 存入redis中，利用redis 的 自增操作来 统计城市的 访问量，或者也可以通过Map 等去统计，然后刷入到存储中 。。方式很多
3.利用echarts+百度地图案例，暂时统计的数据，可以参考echarts官网
