New Cross-Border E-Commerce System | Multi-Language Mall + Merchant Registration + One-Click Product Distribution Complete Deployment Guide

Honestly, the first time I deployed this cross-border e-commerce system, I was confused by its architectural complexity. Four dimensions — user end, merchant end, registration end, and backend — all developed with VUE, with the server-side powered by JAVA. This combination is indeed impressive. After spending some time getting through it, today I am explaining the complete deployment process and core functionalities to everyone.

1. System Architecture and Core Modules

This cross-border e-commerce system adopts a standard front-end and back-end separated architecture. The front-end is unified by VUE, covering four ports: user end, merchant end, registration end, and backend management. The backend is powerfully powered by JAVA, with source code fully open source and available for secondary development. The system natively supports multi-language switching. The merchant registration process is simple and efficient. The one-click product distribution function greatly reduces merchant operating costs, making it an excellent choice for cross-border e-commerce projects.

1. Multi-Language Mall System: Natively supports multi-language switching. All front-end interface copy is internationally configured, enabling quick adaptation to language needs of multiple countries and regions worldwide
2. Merchant Registration System: Complete merchant registration process, including qualification review, contract signing, and store activation. Supports custom registration conditions and review rules
3. One-Click Product Distribution: Supports merchants in quickly distributing products to the platform. Supports batch operations, greatly improving the efficiency of merchants listing products
4. Backend Manual Order Creation: Supports backend manual order creation. Suitable for virtual products, testing scenarios, and special customer service needs
5. Merchant Data Management: Supports setting merchant visits, credit scores, follower counts, and other key metrics. The backend can control the entire process

2. Deployment Preparation and Environment Requirements

• Server: Recommended starting from 4 cores 8G, CentOS 7.x or Ubuntu 20.04 LTS. For cross-border business, it is recommended to choose overseas servers
• JDK version: JDK 1.8 or JDK 11, need to configure JAVA_HOME
• Database: MySQL 5.7+. It is recommended to enable binlog for data synchronization
• Cache: Redis 6.0+ for session caching and queue processing
• Message queue: RabbitMQ for order asynchronous processing
• Node.js: 14.x or 16.x, used for VUE front-end project build
• Nginx: Used for front-end static resource hosting and reverse proxy
• SSL certificate: Let us Encrypt free certificate or commercial certificate
• Storage: Alibaba Cloud OSS or MinIO object storage, used for product images and attachment storage

3. Common Issues and Solutions

3.1 Multi-Language Switching Not Effective

Multi-language configuration check: Confirm that language pack files are placed in the /src/locales/ directory, with file names corresponding to language codes (such as zh-CN.js, en.js). Second, check whether the Vue-i18n plugin is correctly mounted. The import order in main.js is very important.

3.2 Merchant Registration Review Failure

Registration review exceptions are usually caused by failed qualification image upload or unsupported file format. The system supports JPG, PNG, and WebP formats, with a single file size limit of 10MB. It is recommended to check whether OSS configuration is correct and whether the callback address is reachable.

3.3 One-Click Product Distribution Function Exception

The system does not have pre-installed product data by default. Merchants need to add their own products before they can use the one-click product distribution function. If distribution fails, please check whether the product category is set correctly and whether the inventory is sufficient.

3.4 Backend Manual Order Creation Failure

Manual order creation requires selecting a product, buyer, and shipping address. None can be missing. If order creation fails, please check whether the order service is normal and whether the inventory is sufficient. After order creation, it will trigger message queue asynchronous processing. Pay attention to checking the consumer service status.

4. Secondary Development and Customization Guide

The system back-end uses the Spring Boot plus MyBatis Plus framework, with a clear code structure and complete comments. The front-end VUE uses Vue3 plus Vite development, with a high degree of componentization. When conducting secondary development, it is recommended to first familiarize yourself with the project structure: user end code is in /src/views/user/, merchant end is in /src/views/merchant/, and backend is in /src/views/admin/. When adding new features, follow the established directory structure and naming conventions.

The most common customization requirement for cross-border e-commerce systems is payment interface integration. The system has integrated Alipay and WeChat Pay SDKs. If you need to integrate other payment channels (such as PayPal or Stripe), you only need to add an adapter for the corresponding channel in the /src/payment/ directory.

Important Tip: The cross-border e-commerce system involves cross-border transactions and payment functions. Before deployment, please make sure your business qualifications include relevant permits, especially cross-border payment and foreign exchange settlement related qualifications. It is recommended to consult a professional legal consultant to ensure the business model complies with Chinese and target market local laws and regulations requirements.

5. FAQ

Q1: Which languages does the system support?
A1: The system natively supports Simplified Chinese, Traditional Chinese, English, Japanese, and Korean five languages. If you need to add other languages, you only need to add a new language pack file in the /src/locales/ directory and register it in the language configuration file.

Q2: What qualifications are needed for merchant registration?
A2: The system supports custom registration condition configuration. The default requirements include business license, legal person ID card, and bank account information. If you need to add other qualification requirements, you can configure them in Backend – Registration Settings.

Q3: Does one-click product distribution support batch operations?
A3: Yes. Merchants can check multiple products and then one-click distribute them to the store. You can also set up automatic distribution rules so that when new products are listed, they are automatically synchronized to specified stores.

Q4: How to trace backend manually created orders?
A4: Manually created orders will be marked with “Backend Manual Creation” for easy identification in order details where you can view the creator and creation time, facilitating business tracing and reconciliation.

Q5: How is merchant credit score calculated?
A5: Merchant credit scores are automatically calculated by the system based on order completion rate, refund rate, positive review rate, and other metrics. Backend administrators can also manually adjust scores. Credit scores directly affect the merchant display weight on the platform.
