# java获取全国各地省份、城市名称 #

自己封装的java工具类，可以用来获取各地的省份城市名称。项目文件存在了云盘，直达链接：[http://pan.baidu.com/s/1o82dPNG][http_pan.baidu.com_s_1o82dPNG] 密码：dgcg

**一、需要准备一下几个东西：**

**1. qq安装目录下的地区xml**

![Center][]![SouthEast][]

**2****.dom4j jar 包**

下载地址：[http://www.dom4j.org/dom4j-1.6.1/][http_www.dom4j.org_dom4j-1.6.1]

**二、代码**

**三、测试**

package test;
    
    import java.util.List;
    
    import cn.wtzvae.util.LocalUtil;
    
    
    public class TestLocalUtil {
    	public static void main(String[] args) {
    		LocalUtil lu =  LocalUtil.getInstance();
    		List<String> list = 	lu.getCities("中国", "广东");
    		for(int i=0; i<list.size(); i++){
    			System.out.print(list.get(i) + " ");
    		}
    	}
    }
