**基于Spring Boot的海南自贸港一体化智慧服务平台设计与实现**
海南自贸港建设涉及国际贸易、投资管理、政务服务等多元业务场景,传统服务平台存在系统孤岛、流程繁琐等问题。本文设计并实现了一个基于Spring Boot的海南自贸港智慧服务平台,通过微服务架构与智能技术融合,构建跨部门协同、全流程覆盖的综合性 服务枢纽。
### 一、 系统架构设计
系统采用“平台+应用”的中台架构,构建统一技术底座与业务能力中心。
**技术架构**:
- 后端框架:Spring Boot 2.7 + Spring Cloud Alibaba 2021 + Spring Security
- 服务治理:Nacos 2.1(服务发现与配置中心)
- 分布式事务:Seata 1.5(分布式事务管理)
- 数据存储:OceanBase 3.2(分布式数据库)+ Redis 7.0(缓存)+ Elasticsearch 7.17(搜索)
- 区块链服务:FISCO BCOS 3.0(贸易数据存证)
- API网关:Spring Cloud Gateway
- 业务流程:Camunda 7.17(工作流引擎)
- 前端框架:Vue 3 + Ant Design Pro
**核心能力中心**:
1. 统一身份认证与权限中心
2. 国际贸易单一窗口服务
3. 跨境投资一站式办理
4. 智慧税务与海关协同
5. 数据共享与分析决策
### 二、 核心功能模块实现
