我是靠谱客的博主阔达烤鸡，最近开发中收集的这篇文章主要介绍JAVA调用百度地图API获取地理信息百度地图API之JAVA，觉得挺不错的，现在分享给大家，希望可以做个参考。

百度地图API之JAVA

JAVA调用百度地图API获取地理信息工具

注意: 没有认证的(服务器端)AK每天只能使用6000次左右

-- 百度控制台申请AK,注册登录->应用管理->我的应用->创建应用

1.获取指定行政区的中心经纬度 [getLngAndLatByAddress]

@SpringBootTest
@RunWith(SpringRunner.class)
public class BaiduMap {
final static String AK = "登陆百度地图控制台申请服务端AK";
final static String ADDRESS_TO_LONGITUDEA_URL = "http://api.map.baidu.com/geocoding/v3/?output=json";
final static String ADDRESS = "河南省洛阳市";
@Test
public void getLngAndLatByAddress() {
if (!StringUtils.isBlank(ADDRESS)) {
String url = ADDRESS_TO_LONGITUDEA_URL + "&ak=" + AK + "&address=" + ADDRESS;
HttpClient client = HttpClients.createDefault(); // 创建默认http连接
HttpPost post = new HttpPost(url);// 创建一个post请求
try {
HttpResponse response = client.execute(post);// 用http连接去执行get请求并且获得http响应
HttpEntity entity = response.getEntity();// 从response中取到响实体
String json = EntityUtils.toString(entity);// 把响应实体转成文本
// JSON转对象
if (json != null && !"".equals(json)) {
JSONObject obj = JSONObject.fromObject(json);
if ("0".equals(obj.getString("status"))) {
// status 状态码 0-成功
}
}
} catch (Exception e) {
}
}
}
}

响应:

{
"status": 0,
"result": {
"location": {
"lng": 112.4594212983115,
"lat": 34.62426277921943
},
"precise": 0,
"confidence": 20,
"comprehension": 100,
"level": "城市"
}
}

2.获取指定经纬度的行政区信息 [getRegionByLngAndLat]

@SpringBootTest
@RunWith(SpringRunner.class)
public class BaiduMap {
final static String AK = "登陆百度地图控制台申请服务端AK";
final static String LOCATION_TO_LONGITUDEA_URL = "http://api.map.baidu.com/reverse_geocoding/v3/?output=json";
final static String LNG = "112.459420";
final static String LAT = "34.624264";
@Test
public void getRegionByLngAndLat() {
String url = LOCATION_TO_LONGITUDEA_URL+"&ak="+AK+"&location="+LAT+","+LNG;
HttpClient client = HttpClients.createDefault(); // 创建默认http连接
HttpPost post = new HttpPost(url);// 创建一个post请求
try {
HttpResponse response = client.execute(post);// 用http连接去执行get请求并且获得http响应
HttpEntity entity = response.getEntity();// 从response中取到响实体
String json = EntityUtils.toString(entity);// 把响应实体转成文本
// JSON转对象
if (json != null && !"".equals(json)) {
JSONObject obj = JSONObject.fromObject(json);
if ("0".equals(obj.getString("status"))) {
String regionCode = obj.getJSONObject("result").getJSONObject("addressComponent").getString("adcode"); // 区域编码
}else if("302".equals(obj.getString("status"))){
// 302-使用次数超限,认证或第二天继续使用或换一个AK
System.out.println(json);
}
}
} catch (Exception e) {
}
}
}

响应
