# scaffold 项目之配置管理

# 简介

在一个业务中,难免需要动态修改某个配置,比如可能需要更换新的 地图key , 或者创建用户的时候的默认密码等等。

# 使用

在 [基础设施 -> 配置管理] 菜单,可以查看和管理配置,适合业务上需要动态的管理某个配置。

# 配置的表结构

CREATE TABLE `infra_config` (
  `id` int NOT NULL AUTO_INCREMENT COMMENT '参数主键',
  `group` varchar(50) CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci NOT NULL COMMENT '参数分组',
  `type` tinyint NOT NULL COMMENT '参数类型',
  `name` varchar(100) CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci NOT NULL DEFAULT '' COMMENT '参数名称',
  `key` varchar(100) CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci NOT NULL DEFAULT '' COMMENT '参数键名',
  `value` varchar(500) CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci NOT NULL DEFAULT '' COMMENT '参数键值',
  `sensitive` bit(1) NOT NULL COMMENT '是否敏感',
  `remark` varchar(500) CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci DEFAULT NULL COMMENT '备注',
  `creator` varchar(64) CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci DEFAULT '' COMMENT '创建者',
  `create_time` datetime NOT NULL DEFAULT CURRENT_TIMESTAMP COMMENT '创建时间',
  `updater` varchar(64) CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci DEFAULT '' COMMENT '更新者',
  `update_time` datetime NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP COMMENT '更新时间',
  `deleted` bit(1) NOT NULL DEFAULT b'0' COMMENT '是否删除',
  PRIMARY KEY (`id`) USING BTREE
) ENGINE=InnoDB AUTO_INCREMENT=8 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci COMMENT='参数配置表';

key 字段,对应到 Spring Boot 配置文件的配置项,例如说 scaffold.captcha.enablesys.user.init-password 等等

简要说明:

  1. 可以查询对应的配置
  2. 可以修改对应的配置
