废话不多说，直接上代码：

package com.gamesvr.framework.util;
    
    import java.io.BufferedReader;
    import java.io.IOException;
    import java.io.InputStreamReader;
    import java.net.MalformedURLException;
    import java.net.URL;
    import java.net.URLConnection;
    
    import net.sf.json.JSONObject;
    
    public class GetLatAndLngByBaidu { 
    	
    	    public static String getCoordinate(String lng,String lat) throws IOException { 
    	    	StringBuilder resultData = new StringBuilder();
    	    	//秘钥换成你的秘钥，申请地址在下边
    	        String url ="http://api.map.baidu.com/geocoder/v2/?ak="+"你的秘钥"+"&location=" + lat + ","+ lng + "&output=json&pois=1";
    	        URL myURL = null; 
    	        URLConnection httpsConn = null;
    	        try { 
    	            myURL = new URL(url); 
    	        } catch (MalformedURLException e) { 
    	            e.printStackTrace(); 
    	        } 
    	        InputStreamReader insr = null;
    	        BufferedReader br = null;
    	        try { 
    	            httpsConn = (URLConnection) myURL.openConnection();// 不使用代理 
    	            if (httpsConn != null) { 
    	                insr = new InputStreamReader( httpsConn.getInputStream(), "UTF-8"); 
    	                br = new BufferedReader(insr); 
    	                String data = null; 
    	                while((data= br.readLine())!=null){ 
    	                	 resultData.append(data);
    	                } 
    	            } 
    	        } catch (IOException e) { 
    	            e.printStackTrace(); 
    	        } finally {
    	            if(insr!=null){
    	                insr.close();
    	            }
    	            if(br!=null){
    	                br.close();
    	            }
    	        }
    	        String province= JSONObject.fromObject(resultData.toString()).getJSONObject("result")
    	        		.getJSONObject("addressComponent").getString("province"); 
    	        return province;
    	    }
    	    
    	    public static void main(String[] args) throws IOException {
    	        String o = GetLatAndLngByBaidu.getCoordinate("117.2317","39.5427");
    	    }
    	}

这里是获取的省一级的名字，如果是想获取城市的名字，把下边这句话的province改成city即可

String city= JSONObject.fromObject(resultData.toString()).getJSONObject("result")
    	        		.getJSONObject("addressComponent").getString("city");

运行结果：
