复制该内容到json文件,保存。

复制JSON文件到项目

1. 在resources下创建一个json文件夹，复制json文件到文件夹中
2. 配置一下，我直接放在 启动类 中配置的，也可以自行构建配置类

    /*** 读取JSON文件* @return* @throws IOException*/@Beanpublic List<CarAreaModel> getCarAreaJSON() throws IOException {InputStream inputStream = getClass().getResourceAsStream("/json/carArea.json");if(inputStream==null){throw new RuntimeException("读取车牌归属地json文件失败！！！");}else{JSONObject json = JSON.parseObject(inputStream, JSONObject.class);JSONArray array = json.getJSONArray("codeInfo");return array.toJavaList(CarAreaModel.class);}}

3. CarAreaModel实体类

public class CarAreaModel implements Serializable {/*** 车牌前两位*/private String Hp;/*** 城市*/private String city;/*** 省*/private String province;/*** 拼音缩写*/private String Pcode;/*** 地区代码*/private String AreaCode;
}

使用

1. 在需要使用的地方注入

    /*** 车牌号归属地JSON*/@Autowiredprivate List<CarAreaModel> areaJsonList;

2. 获取地区

    /*** 根据车牌号计算归属地* @param cph* @return*/private String getGsd(String cph){String msg = "";//号牌前2位，例如陕AString hp = cph.substring(0, 2);for (CarAreaModel carAreaModel : areaJsonList) {if (hp.equals(carAreaModel.getHp())){msg = carAreaModel.getProvince()+carAreaModel.getCity();break;}}return msg;}

到此就完事了！！！
