让isis支持高德地图

篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了让isis支持高德地图相关的知识,希望对你有一定的参考价值。

概述

由于项目需要用到地图,虽然isis的插件库里有个现成的地图实现,不过用的google地图,虽然google地图可以不用注册Appkey,但完全打不开。所以打算改成国产地图。

效果

先看下运行效果。

实现思路

高德地图的API跟Google地图类似,编程模型也相同,甚至很多类的命名都一样的。所以,从Google迁到高德还是比较容易的。

高德跟Google一样,用一个DIV来渲染地图。根据Vicket的编程方式,这个Div使用一个组件来表示,这个组件包含了相应的属性和呈现出来的模板及脚本。

先看下Google的模板,很简单在Panel里放了一个Div:

<html xmlns:wicket>
    <body>
    <wicket:panel>
        <div wicket:id="map" style="width:100%; height:100%"></div>
    </wicket:panel>
</body>
</html>

 Google的客户端对应的初始化脚本:

 Java部分的实现,可以看出其属性与客户端的JS是一一对应的,这是Vicket的一种机制,将服务端的对象映射到客户端,这样在服务端设置属性就跟在客户端设置一样:

 看下怎么往地图上添加标记,可以看到我们不用直接在客户端写JS,服务端操作即可:

	private GMap buildGui() {

		final EntityModel model = getModel();
		final ObjectAdapter adapter = model.getObject();
		Location l = (Location) adapter.getObject();
		GLatLng latLng = new GLatLng(l.getLatitude(), l.getLongitude());

		final boolean visible = latLng != null;

		final GMap map = new GMap(ID_MAP, apiKey);
		// map.setStreetViewControlEnabled(true);
		map.setScaleControlEnabled(false);
		map.setPanControlEnabled(false);
		map.setDoubleClickZoomEnabled(false);
		map.setZoom(17);

		if (visible) {

			// centre the map on the first object that has a location.
			map.setCenter(latLng);
		}

		addOrReplace(map);

		addMarker(map, adapter);

		return map;
	}

	private void addMarker(final GMap map, ObjectAdapter adapter) {

		ObjectAdapter dereferencedAdapter = dereference(adapter);

		final GMarker gMarker = createGMarker(map, adapter, dereferencedAdapter);
		if (gMarker != null) {
			map.addOverlay(gMarker);
			// addClickListener(gMarker, dereferencedAdapter);
		}
		List<GLatLng> glatLngsToShow = Lists.newArrayList();
		map.fitMarkers(glatLngsToShow);
	}

下边开始尝试替换相应的内容:

GMapHeaderContributor类,改成高德的接口

public class GMapHeaderContributor extends Behavior {

	private static final long serialVersionUID = 1L;
	// URL for Google Maps\' API endpoint.
	private static final String GMAP_API_URL = "%s://webapi.amap.com/maps?v=1.3&key=%s";
	private static final String HTTP = "http";
	// We have some custom Javascript.
	private static final ResourceReference WICKET_GMAP_JS = new JavaScriptResourceReference(GMap.class,
			"wicket-gmap.js");

//...
}

wicket-gmap.js

//...
//地图对象的实例化
function WicketClientGeocoder() {

    this.coder = new AMap.Geocoder();

    this.getLatLng = function(callBack, addressId){
    
        var address = Wicket.$(addressId).value;
        
        this.coder.geocode({
            \'address\': address
        }, function(results, status){
        
            var params = {};
            if (status == AMap.GeocoderStatus.OK) {
                params[\'address\'] = results[0].formatted_address;
                params[\'coordinates\'] = results[0].geometry.location;
                params[\'status\'] = status;
            }
            
            for ( var key in params) {
                callBack = callBack + \'&\' + key + \'=\' + params[key];
            }
            
            Wicket.Ajax.ajax({
                \'u\':callBack, 
                \'ep\': params
            });
        });
    }
}

//其它API有差异的地方也相应的改一下,此处略
//...
