+### 🧭 dev 与 dev_local_backend 巡航指南
+
+在需要本地 IDE 启动后端、而容器只提供 MySQL、Redis、RabbitMQ、OpenSearch 等依赖时，可切换到 `dev_local_backend` Profile：
+
+```bash
+docker compose \
+  -f docker/docker-compose.yaml \
+  --env-file .env \
+  --profile dev_local_backend up -d
+```
+
+> [!TIP]
+> 该 Profile 不会启动 Docker 内的 Spring Boot 服务，`frontend_dev_local_backend` 会通过 `host.docker.internal` 访问你本机正在运行的后端。非常适合用 IDEA/VS Code 调试 Java 服务的场景！
+
+| 想要的体验 | 推荐 Profile | 会启动的关键容器 | 备注 |
+| --- | --- | --- | --- |
+| 🚀 一键启动前后端 | `dev` | `springboot`、`frontend_dev`、`mysql`… | 纯容器内跑全链路，省心省力 |
+| 🛠️ IDE 启动后端 + 容器托管依赖 | `dev_local_backend` | `frontend_dev_local_backend`、`mysql`、`redis`… | 记得本地后端监听 `8080`/`8082` 等端口 |
+
+切换 Profile 时，请先停掉当前组合再启动另一组，避免端口占用或容器命名冲突：
+
+```bash
+docker compose -f docker/docker-compose.yaml --env-file .env --profile dev down
+# 或者
+docker compose -f docker/docker-compose.yaml --env-file .env --profile dev_local_backend down
+```
+
+常见小贴士：
+
+- 🧹 需要彻底清理依赖时，别忘了追加 `-v` 清除持久化数据卷。
+- 🪄 仅切换 Profile 时通常无需重新 `build`，除非你更新了镜像依赖。
+- 🧪 如需确认前端容器访问的是本机后端，可在 IDE 控制台查看请求日志或执行 `curl http://localhost:8080/actuator/health` 进行自检。

 ## 启动后端服务
 
 启动后端服务有多种方式，选择一种即可。

+> [!WARNING]
+> 如果你通过 `dev_local_backend` Profile 启动了数据库/缓存等依赖，却让后端由 IDEA 在宿主机运行，请务必将 `open-isle.env`（或 IDEA 的环境变量面板）中的主机名改成 `localhost`：
+>
+> ```ini
+> MYSQL_HOST=localhost
+> REDIS_HOST=localhost
+> RABBITMQ_HOST=localhost
+> ```
+>
+> 对应的容器端口均已映射到宿主机，无需额外配置。若仍保留默认的 `mysql`、`redis`、`rabbitmq`，IDEA 将尝试解析容器网络内的别名而导致连接失败。
+
 也可以修改 `src/main/resources/application.properties`，但该文件会被 Git 追踪，通常不推荐。
