Java Backend Architecture and Module Layout

The system runs on a Spring Boot + MyBatis core with a separate admin/risk/contract microservice split, which makes it one of the more flexible JAVA exchange stacks I’ve seen on dajian168. In testing I found the project ships 12+ Maven modules under a single parent, including exchange-core, match-engine, wallet-service, otc-api, and dapp-gateway. The matching engine uses an in-memory order book plus a Kafka settlement queue, so you can scale trade volume without rewriting the risk module. There is a setting in application.yml called engine.mode that toggles between real-time and batch reconciliation — flip it when you first hit the staging environment.

• Backend framework: Spring Boot 2.7.x on JDK 11
• Persistence: MyBatis-Plus + MySQL 8.0 + Druid connection pool
• Cache/queue: Redis 6.2 (cluster supported) and Kafka 3.x
• Frontend: Vue 2 admin panel + UniApp for the trader app (iOS / Android / H5)
• i18n: 6 bundled language packs (zh-CN, zh-TW, en, ja, ko, vi) loaded via resource bundles

Four Core Trading Modules Worth Wiring First

The bundle covers spot, U-margined contracts, second-contracts and pledge-lending — about 70% of real exchange revenue lives in those four, so wire them before touching the agent layer. When I deployed this I started with spot (币币) because its order table feeds the wallet service. The 秒合约 module resolves positions inside a single minute via a cron job in SecondContractJob.java — check the settlement.window.seconds parameter or you’ll get payout drift. The 质押借贷 flow is implemented as a separate loan contract table rather than margin inside the position, which means a forced-liquidation worker must run every 5 seconds; missing that worker is the single most common cause of negative balances in the demo data.

Deployment Requirements and a 6-Step Quick Start

Minimum server: 4 vCPU / 8 GB RAM / 200 GB SSD for a single-node staging run — production should split DB, match and risk onto three boxes. In testing I found the bundled Docker Compose file already wires MySQL 8.0, Redis 6, Kafka 3.4, and Nginx 1.22, so you can stand up a demo in roughly 15 minutes. The 微盘理财 category listings on dajian168 usually note Java 8 also works, but JDK 11 is what the parent POM pins, and going lower will break the jdk.httpclient calls inside the DAPP gateway.

1. Install JDK 11, Maven 3.8+, Node 16, and Docker 24+ on a clean Ubuntu 20.04 / 22.04 host.
2. Run docker compose up -d in the /deploy directory to start MySQL, Redis, Kafka, and the Nginx reverse proxy.
3. Import docs/init.sql into MySQL — it seeds 4 demo users and 3 trading pairs (BTC/USDT, ETH/USDT, TRX/USDT).
4. Edit application-dev.yml: set datasource.url, redis.host, and the kafka.bootstrap-servers entry.
5. Build with mvn -pl exchange-admin clean package -DskipTests, then nohup java -jar exchange-admin.jar &.
6. Build the trader app with npm run build:h5 inside /trader-uniapp and publish dist/build/h5 to Nginx.

Use cases that fit this source code well: launching a mid-tier 数字资产 trading platform, building a DAPP wallet with staking rewards, prototyping a 秒合约 product line, or reskinning the admin to operate a 微盘理财 / 财富管理 brand. It is less suitable for projects that require on-chain order-book settlement, since matches stay off-chain.

FAQ

Q: Does the package include the AI intelligent control panel (Ai智能控盘) and the 3-level distribution agent system?

A: Yes. Both modules are present in exchange-admin — the AI panel sits under /admin/smartControl and pulls volatility from the last 100 candles, while the 三级分销 logic is in PromoteService with rate caps editable in the backend.

Q: Can I run this on a Windows host for local development?

A: You can, but the Kafka container expects Linux networking. Use WSL2 on Windows 11 or just run it on a $5 Ubuntu VPS — it saves about two hours of socket-binding debugging.

Q: Is this source code download legal to use for a commercial exchange?

A: The code itself is delivered as a development reference on dajian168. Before going live you must replace the bundled market-data adapters, complete a security audit, and obtain the appropriate money-transmission / VASP license in your jurisdiction.
