1. 业务开发

2. 将github数据库文件转换成city表步骤

2.1. 下载sql文件

2.2. sqlLite迁移到mysql

2.2.1. navicat新建sqlLite数据库

2.2.2. 执行sql

CREATE TABLE "cms_city" (
  "id" integer NOT NULL PRIMARY KEY AUTOINCREMENT,
  "province_id" integer(20),
  "province_name" text(64),
  "city_id" integer(20),
  "city_name" text(64),
  "county_id" integer(20),
  "county_name" text(64),
  "town_id" integer(20),
  "town_name" text(64),
  "village_id" integer(20),
  "village_name" text(64)
);


INSERT INTO cms_city(village_id,village_name,town_id,county_id,city_id,province_id,town_name,county_name,city_name,province_name) SELECT * FROM (

(SELECT
    vsac.*,
    province.`name` AS province_name 
FROM
    (
        (
        SELECT
            vsa.*,
            city.`name` AS city_name 
        FROM
            (
                (
                SELECT
                    vs.*,
                    area.`name` AS county_name
                FROM
                    (
                        (
                        SELECT
                            village.`code` AS village_id,
                            village.`name` AS village_name,
                            village.streetCode AS town_id,
                            village.areaCode AS county_id,
                            village.cityCode AS city_id,
                            village.provinceCode AS province_id,
                            street.`name` AS town_name
                        FROM
                            village
                            LEFT JOIN street ON village.streetCode = street.`code` 
                        ) AS vs 
                    )
                    LEFT JOIN area ON area.`code` = vs.county_id 
                ) AS vsa 
            )
            LEFT JOIN city ON city.`code` = vsa.city_id 
        ) AS vsac 
    )
    LEFT JOIN province ON province.`code` = vsac.province_id) as city

);

update cms_city set city_id = city_id *100000000,county_id = county_id*1000000,town_id = town_id*1000;

2.2.3. 导出cms_city

2.2.4. 在mysql创建city表

CREATE TABLE `city` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `province_id` bigint(20) unsigned DEFAULT NULL COMMENT '省编号',
  `province_name` varchar(64) DEFAULT NULL COMMENT '省名称',
  `city_id` bigint(20) unsigned DEFAULT NULL COMMENT '城市编号',
  `city_name` varchar(64) DEFAULT NULL COMMENT '城市名称',
  `county_id` bigint(20) unsigned DEFAULT NULL COMMENT '区编号',
  `county_name` varchar(64) DEFAULT NULL COMMENT '区名称',
  `town_id` bigint(20) unsigned DEFAULT NULL COMMENT '镇\\县编号',
  `town_name` varchar(64) DEFAULT NULL COMMENT '镇\\县名称',
  `village_id` bigint(20) unsigned DEFAULT NULL COMMENT '街道编号',
  `village_name` varchar(64) DEFAULT NULL COMMENT '街道名称',
  PRIMARY KEY (`id`) USING BTREE,
  KEY `province_id` (`province_id`) USING BTREE,
  KEY `city_id` (`city_id`) USING BTREE,
  KEY `county_id` (`county_id`) USING BTREE,
  KEY `town_id` (`town_id`) USING BTREE,
  KEY `village_id` (`village_id`) USING BTREE,
  KEY `id` (`id`) USING BTREE
) ENGINE=InnoDB AUTO_INCREMENT=604852 DEFAULT CHARSET=utf8mb4 ROW_FORMAT=DYNAMIC COMMENT='省市县镇村数据';

2.2.5.

2.2.6. 在mysql数据库还原

2.2.7.

通过代码生成器拖拽城市控件自动生成城市业务代码。

2.3. /static/json/city.json

通过城市管理手动生成city.json文件，可以减少城市的数据查询效率问题

ms.http.get("/static/json/city.json").then(function (data) {

   if (data.result) {

     that.provinces = data.data;

   }

});
