-### Docker镜像源设置
-
-```bash
-# 创建目录
-sudo mkdir -p /etc/docker
-# 写入配置文件
-sudo tee /etc/docker/daemon.json <<-'EOF'
-{
-    "registry-mirrors": [
-    	"https://docker-0.unsee.tech",
-        "https://docker-cf.registry.cyou",
-        "https://docker.1panel.live"
-    ]
-}
-EOF
-
-# 重启docker服务
-sudo systemctl daemon-reload && sudo systemctl restart docker
-```
-
-使用docker-compose有的时候会因为版本不同，但是配置文件主要内容就是这些。需要注意版本问题
-
-### 配置相关
-
-#### MySQL配置问题
-
-| **特性**   | `**my.cnf**`        | `**conf.d**` **目录** |
-|----------|:--------------------|:-------------------:|
-| **文件类型** | 单个文件                |  目录，包含多个 `.cnf` 文件  |
-| **配置方式** | 集中式配置               |        分布式配置        |
-| **优先级**  | 高（覆盖 `conf.d` 中的配置） |  低（被 `my.cnf` 覆盖）   |
-| **适用场景** | 全局配置，核心配置           |    模块化配置，便于扩展和维护    |
-
-#### MongoDB配置
-
-```bash
-sudo mkdir -p ~/docker/docker_data/mongo/conf
-sudo mkdir -p ~/docker/docker_data/mongo/logs
-sudo chmod 777 ~/docker/docker_data/mongo/logs
-sudo chmod 777 ~/docker/docker_data/mongo/conf
-
-cd ~/docker/docker_data/mongo/logs
-sudo touch mongod.log
-sudo chmod 777 mongod.log
-
-cd ~/docker/docker_data/mongo/conf
-sudo vim mongod.conf
-
-cd ~
-```
-
-##### 配置文件
-
-```bash
-# 数据库文件存储位置
-dbpath = /data/db
-# log文件存储位置
-logpath = /data/log/mongod.log
-# 使用追加的方式写日志
-logappend = true
-# 是否以守护进程方式运行
-# fork = true
-# 全部ip可以访问
-bind_ip = 0.0.0.0
-# 端口号
-port = 27017
-# 是否启用认证
-auth = true
-# 设置oplog的大小(MB)
-oplogSize=2048
-```
-
-##### 设置账户密码
-
-```shell
-#进入容器
-docker exec -it mongodb /bin/bash
-
-#进入mongodb shell
-mongosh --port 27017
-
-#切换到admin库
-use admin
-
-#创建账号/密码
-db.createUser({ user: 'admin', pwd: '02120212', roles: [ { role: "root", db: "admin" } ] });
-# db.createUser({ user: 'admin', pwd: '123456', roles: [ { role: "userAdminAnyDatabase", db: "admin" } ] });

+![数据隔离架构图](./images/image-20250526160251551.png)
+
+### 命名空间管理
 
 #### 创建命名空间
 
 > [!TIP]
->
-> 如果需要导入和我一样的命名空间，可以在项目目录下的samples文件找到相关配置
+> 预配置的命名空间示例可在项目 `samples/namespace-config` 目录下找到。
 
-分别创建：test、prod、dev
+建议创建以下标准命名空间：
 
-![image-20250526160457765](./images/image-20250526160457765.png)
+- `dev` - 开发环境
+- `test` - 测试环境
+- `prod` - 生产环境
 
-![image-20250526160718723](./images/image-20250526160718723.png)
+**操作步骤**：
 
-之后到配置列表中创建配置（dev命名空间）
+1. 进入Nacos控制台命名空间管理
+2. 点击"新建命名空间"
+3. 填写命名空间信息（ID和名称）

+![命名空间列表](./images/image-20250526160718723.png)
 
-```yml
+#### 配置管理
+
+**开发环境配置示例**：
+
+1. 基础配置：
+
+```yaml
 order:
   timeout: 1min
   auto-confirm: 1h
 ```
 
-![image-20250526160842062](./images/image-20250526160842062.png)
+2. 数据库配置：
 
-```yml
+```yaml
 order:
-  db-url: order_dev
+  db-url: jdbc:mysql://dev-db:3306/order_dev
 ```
 
-#### 克隆命名空间

+
+### 动态环境配置
+
+#### Spring Boot 配置方案
+
+**基础配置**：
+
+```yaml
+server:
+  port: 8000
+spring:
+  application:
+    name: service-order
+  profiles:
+    active: dev
+  cloud:
+    nacos:
+      server-addr: ${NACOS_HOST:192.168.95.135}:8848
+      config:
+        namespace: ${spring.profiles.active:dev} # 动态匹配当前profile
+        group: DEFAULT_GROUP
+```
+
+**多环境配置加载**：
+
+```yaml
+spring:
+  config:
+    import:
+      - optional:nacos:service-order.yml
+      - optional:nacos:common.yml?group=order
+      - optional:nacos:database.yml?group=order
+```
+
+> [!NOTE]
+> 使用`optional:`前缀可避免配置不存在时启动失败
+
+### 配置读取实现
+
+**配置类**：
+
+```java
+@Configuration
+@ConfigurationProperties(prefix = "order")
+@Getter
+@Setter
+public class OrderProperties {
+    private String timeout;
+    private String autoConfirm;
+    private String dbUrl; // 自动映射db-url
+}
+```
+
+**REST接口**：
+
+```java
+@RestController
+@RequestMapping("/api/order")
+@RequiredArgsConstructor
+public class OrderController {
+    private final OrderProperties orderProperties;
+
+    @GetMapping("/config")
+    public Map<String, String> getConfig() {
+        return Map.of(
+            "timeout", orderProperties.getTimeout(),
+            "autoConfirm", orderProperties.getAutoConfirm(),
+            "dbUrl", orderProperties.getDbUrl()
+        );
+    }
+}
+```
