上述问题的解决方案：

roomsLayerEventMouserOver(layer)  {
    if( this.select ){
        this.map.removeInteraction(this.select);
    }

    this.select = new ol.interaction.Select({
        condition: ol.events.condition.pointerMove,
        layers: [
            layer
        ],
        style: (feature) => { return this.roomsSelectedFeatureStyle(feature); }

    });

    this.map.addInteraction(this.select);
}


roomsSelectedFeatureStyle(feature) {
    let roomNumber = feature.getProperties().name ? feature.getProperties().name : " ";
    let style;

    style = new ol.style.Style({
        text: new ol.style.Text({
            text: roomNumber
        }),
        stroke: new ol.style.Stroke({
            color: LAYER_ROOM_HIGHLIGTH_COLOR_BORDER,
            width: 1
        }),
        fill: new ol.style.Fill({
            color: LAYER_ROOM_HIGHLIGTH_COLOR_FILL
        })

    });

    return style;
