Handles drag-and-drop row sorting for the JVxeTable component with support for virtual scrolling and fixed columns. Demonstrates a reusable pattern for implementing sortable tables in Vue 3 that can be extracted and adapted to other table libraries.

Generates MyBatis-Plus QueryWrapper instances from entity annotations and request parameters, supporting complex query conditions (EQ, LIKE, BETWEEN, etc.) with SQL injection prevention. This utility is self-contained and can be reused in any Spring Boot project to eliminate boilerplate query code.

AOP aspect that validates API request signatures using HMAC-SHA256, preventing tampering and replay attacks. It is configurable via annotation and can be extracted as a standalone security module for any REST API.

Aspect that automatically encrypts/decrypts sensitive fields (e.g., phone, ID card) on database read/write using annotations. Implements a clean separation of concerns and can be reused in any Java application requiring data desensitization.

Provides a reactive table instance with methods for reload, column manipulation, selection, pagination, and export. This composable encapsulates common table operations and can be reused across Vue 3 projects with any table component.
