Java解析省份城市

• json文件：

	public String formatAddr(String address){


		if (address == null){
			return null;
		}

		//匹配特殊字符
		String regEx = "[ _`~!@#$%^&*()+=|{}':;',\[\].<>/?~！@#￥%……&*-（）——+|{}【】‘；：”“’。，、？]|n|r|t";
		Pattern p = Pattern.compile(regEx);
		Matcher m1 = p.matcher(address);

		//处理特殊字符
		if (m1.find()){
			for (char c : regEx.toCharArray()) {
				String value = String.valueOf(c);
				if (address.contains(value)){
					address = address.replace(value,"");
				}
			}
		}
		String regex="(?[^省]+自治区|.*?省|.*?行政区|.*?市)(?[^市]+自治州|.*?地区|.*?行政单位|.+盟|市辖区|.*?市|.*?县)";
		Matcher m=Pattern.compile(regex).matcher(address);
		String province=null,city=null;
		while(m.find()){
			province=m.group("province");
			city=m.group("city");
		}

		if (province == null || city == null){
			return null;
		}

		JSONArray jsonArray = readJson();

		for (Object obj: jsonArray) {
			JSONObject jsonObject = JSONUtil.parseObj(obj);
			String label = jsonObject.getStr("label");
			if (label.equals(province)){
				//如果省份一致则对比城市是否一致
				JSONArray childrens = jsonObject.getJSONArray("children");
				if (childrens != null){
					for (Object children : childrens) {
						JSONObject cityObj = JSONUtil.parseObj(children);
						if (cityObj.getStr("label").equals(city)){
							return province + "-" + city;
						}
					}
				}
			}
		}

		return null;

	}

	public static JSONArray readJson(){

		cn.hutool.core.io.resource.ClassPathResource classPathResource = new cn.hutool.core.io.resource.ClassPathResource("city.json");
		InputStream inputStream = classPathResource.getStream();
		try {
			Reader reader = new InputStreamReader(inputStream,"UTF-8");
			int ch = 0;
			StringBuffer sb = new StringBuffer();
			while ((ch = reader.read()) != -1) {
				sb.append((char) ch);
			}
			String toString = sb.toString();
			JSONArray jsonArray = JSONUtil.parseArray(toString);
			return jsonArray;
		} catch (Exception e) {
			e.printStackTrace();
		}

		return null;
	}

将文件放在静态目录下即可
