全新 Admin 操作控制台

Admin Console 控制改版，提供更便捷的操作方式，提升更具观赏性的界面。

支持打开多个配置编辑窗口
全新 DARK 主题
优化 JS 加载方式，提高访问速度

怎样迁移

如题

数据库不可用时给予更明确的错误提示

数据库连接失败，给予用户明确的错误信息反馈。目前信息很笼统，用户无法明确了解数据库错误的异常。

关于配置实时更新的问题

请问一下配置实时更新的实现,是通过client实时发送http请求根据state的值判断是否重载来实现的么

如果你接入 duic 请在这留下联系方式(公司名称: 公司网站URL), 仅作为开源参考, 不作其它用途

请不要在该 issue 提交任何问题, 谢谢配合

启动配置增加固定目录支持

启动配置增加默认扫描 /etc/duic 目录中的配置文件。

目前启动配置扫描的配置在工作目录下的 config 在不同的目录下启动 duic 时需要用户手动设置 user.dir 造成不必要的困扰。现提供固定的配置目录扫描，降低部署的成本，提高应用统一性。

区分开发、测试、正式环境

一点建议，dev级别支持克隆：
-- 应用
|
-- dev（令牌）[config1,config2...]
|
--test（令牌）[config1,config2...]
|
--online（令牌）[config1,config2...]

增加健康检查接口

增加 /api/health 接口，用于检查服务可用状态。

启动增加基本参数校验

在启动前检查必要的参数配置。

如未配置 spring.data.mongo.uri 参数时，提供更加明确的错误信息。

支持 Oracle 存储配置

在 firefox 中配置编辑器一直闪烁

增加获取服务信息接口

增加 /api/info 接口用于获取服务信息。

服务启动报错

第一次启动自动创建表之后，由于我的mysql数据库是InnoDB，不支持FULLTEXT，所以手动将 DUIC_APP表的引擎改成了MyISAM，再次启动服务时就报以下错误说表DUIC_APP已存在，已存在难道就不能再启动？

Reason: liquibase.exception.DatabaseException: (conn=139828) Table 'DUIC_APP' already exists [Failed SQL: CREATE TABLE configcenter.DUIC_APP (ID INT AUTO_INCREMENT NOT NULL, NAME VARCHAR(64) NOT NULL COMMENT '应用名称', PROFILE VARCHAR(64) NOT NULL COMMENT '应用环境', DESCRIPTION VARCHAR(1024) NOT NULL COMMENT '应用描述', TOKEN VARCHAR(64) NULL COMMENT '访问令牌', IP_LIMIT VARCHAR(1024) NULL COMMENT '可访问 IP', V INT NOT NULL COMMENT '应用版本', CREATED_AT timestamp NULL COMMENT '创建时间', UPDATED_AT timestamp NULL COMMENT '修改时间', CONTENT LONGTEXT NULL COMMENT '应用配置内容', USERS VARCHAR(1024) NULL COMMENT '应用所属用户', CONSTRAINT PK_DUIC_APP PRIMARY KEY (ID))]

Deadlock

我使用的是duic 2.2.2版本和MySQL 部署，但是在启动日志中会出现死锁的提示。如下：
