CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Project Overview

Weather data management system -- a multi-module Maven project with a Spring Boot backend and Vue 3 frontend for managing meteorological monitoring data from weather stations.

Backend: Spring Boot 3.5.11, Java 17, Apache Shiro, MyBatis-Plus, Quartz
Frontend: Vue 3 + TypeScript + Vite 5, Element Plus, ECharts, Pinia
Database: MySQL 8.0 (primary), supports Oracle / SQL Server / PostgreSQL / Dameng via dynamic datasource
Cache: Redis (Lettuce client)

Project Conventions

No emoji: Avoid using emoji in code (including variable names, comments, commit messages) and in response messages. Use plain text instead.
Keep CLAUDE.md files current: Any operation that adds, deletes, or modifies files affecting project structure (new modules, new packages, renamed components, dependency changes, config changes, schema changes, etc.) must update the relevant CLAUDE.md file(s) -- top-level for cross-cutting changes, module-level for module-specific changes.

Module Index

Module	Path	Purpose
system-common	`system-common/`	Shared library: base classes, Redis, validation, XSS, utilities
system-dynamic-datasource	`system-dynamic-datasource/`	Multi-datasource support via AbstractRoutingDataSource
system-admin	`system-admin/`	Main Spring Boot application, REST API, jobs, security
weather-data-ui	`weather-data-ui/`	Vue 3 frontend

Each module has its own CLAUDE.md with module-specific architecture and conventions. When working in a module, read that module's CLAUDE.md for context.

Build & Run Commands

Backend

# Build everything (skip tests)
mvn clean package -DskipTests

# Build only system-admin module
cd system-admin && mvn package -DskipTests

# Run with dev profile
cd system-admin && mvn spring-boot:run -Dspring-boot.run.profiles=dev

Main entry: system-admin/src/main/java/com/weather/AdminApplication.java

Frontend

cd weather-data-ui
npm install
npm run dev          # dev server on port 8001
npm run build        # production build
npm run lint         # ESLint on src/**/*.{vue,ts}

Key Configuration

Dev profile: system-admin/src/main/resources/application-dev.yml -- local MySQL (weather_data_system), Redis 127.0.0.1:6379
Prod profile: application-prod.yml -- production configuration with external DB/Redis
project-options.redis.open: toggles Redis caching globally (set via sys_params)
