A lightweight application configuration management method based on JDBC

Abstract

This invention discloses a lightweight application configuration management method based on JDBC. It initializes a configuration table in a relational database, storing configuration class identifiers, configuration item keys, configuration item values, and environment variables. Upon application startup, it queries a set of configuration information based on environment variables using JDBC. The set is then traversed, and the configuration item keys are converted to target attribute names using string splitting and camelCase algorithms to obtain read / write methods and attribute types. Configuration item values ​​are dynamically injected into configuration class instances via reflection. During runtime, a scheduled task periodically detects database configuration changes, identifies changed items, and temporarily stores them in a thread-safe map. Hot configuration updates are then achieved again via reflection. This invention eliminates the need for a separate configuration center service, achieving multi-environment isolation, automatic encryption / decryption, and dynamic hot updates. It offers advantages such as lightweight design, database independence, low learning curve, and flexible deployment.
