参考DEMO：

import { map, mapCommon, MapComponent } from '@kit.MapKit'
import { AsyncCallback } from '@kit.BasicServicesKit'

@Entry
@Component
export struct Test {
  private mapOption?: mapCommon.MapOptions;
  private mapController?: map.MapComponentController;
  private callback?: AsyncCallback<map.MapComponentController>;
  private markers: map.Marker[] = []
  private nums: string = ''

  aboutToAppear(): void {
    this.mapOption = {
      position: {
        target: {
          latitude: 32.120750,
          longitude: 118.788765
        },
        zoom: 15
      }
    }

    // 地图初始化的回调
    this.callback = async (err, mapController) => {
      if (!err) {
        // 获取地图的控制器类，用来操作地图
        this.mapController?.setMyLocationEnabled(true)
        this.mapController?.setMyLocationControlsEnabled(true)
        this.mapController = mapController;

        this.mapController.on("mapClick", (position) => {
          console.info("mapClick", `on-mapClick position = ${position.longitude}`);
        });
        this.mapController.on("markerClick", (marker) => {
          console.info(`on-markerClick position = ${JSON.stringify(marker)}`)
          marker.setInfoWindowVisible(true);
        });

      }
    }
  }

  async setMarkerWithHotels() {
    // this.mapController?.clear()

    for (let i = 0; i < 10; i++) {
      let markerOptions: mapCommon.MarkerOptions = {
        position: {
          latitude: 32.120750 + i * 0.01,
          longitude: 118.788765 + i * 0.01
        },
        rotation: 0,
        title: String(i),
        visible: true,
        zIndex: 0,
        alpha: 1,
        anchorU: 0.5,
        anchorV: 1,
        clickable: true,
        draggable: false,
        flat: false,

        icon: $r("app.media.startIcon")
      };
      console.log(`markerOptions+${JSON.stringify(markerOptions)}`)
      // 新建marker
      let marker = await this.mapController?.addMarker(markerOptions);
      console.log(`marker+${JSON.stringify(marker)}`)
      if (marker) {
        this.markers.push(marker)
        console.log(`marker+${JSON.stringify(this.markers.push(marker))}`)
      }
    }
  }

  build() {
    NavDestination() {
      Stack() {
        Column() {
          MapComponent({
            mapOptions: this.mapOption,
            mapCallback: this.callback,
            // 自定义信息窗
            customInfoWindow: this.customInfoWindow
          })
            .width('100%')
            .height('100%');
        }.width('100%')

        Button() {
          Text('setMarkerWithHotels')
        }.onClick(() => {
          this.setMarkerWithHotels()
        })
      }.height('100%')
    }
  }

  // 自定义信息窗BuilderParam
  @BuilderParam customInfoWindow: ($$: map.MarkerDelegate) => void = this.customInfoWindowBuilder;

  // 自定义信息窗Builder
  @Builder
  customInfoWindowBuilder($$: map.MarkerDelegate) {
    if ($$.marker) {
      Text($$.marker.getTitle())
        .width("50%")
        .height(50)
        .backgroundColor(Color.Green)
        .textAlign(TextAlign.Center)
        .fontColor(Color.Black)
        .font({ size: 25, weight: 10, style: FontStyle.Italic })
        .border({
          width: 3,
          color: Color.Black,
          radius: 25,
          style: BorderStyle.Dashed
        })
    }
  }
