Mybatis PageHelper
Mybatis-PageHelper is a pagination plugin and persistence framework extension for MyBatis. It functions as a physical pagination engine that automatically appends limit and offset clauses to SQL queries to retrieve specific record subsets from a data source.
The project optimizes data retrieval by modifying SQL statements at runtime to reduce memory overhead. It implements database pagination and data set windowing to manage the retrieval of paginated data within Java applications.
The system utilizes a MyBatis interceptor chain for dynamic SQL rewriting and employs database dialects to ensure correct pagination syntax across different vendors. It also handles automatic count query execution to determine total record counts.
Features
- Database Pagination Adapters - Provides a dedicated engine for implementing offset and limit pagination across various database dialects.
- SQL Rewriting - Dynamically rewrites SQL statements to append limit and offset clauses based on pagination parameters.
- Pagination - Manages the retrieval of paginated data specifically for Java applications using the MyBatis framework.
- Database Pagination Engines - Functions as a physical pagination engine that fetches specific record subsets to minimize memory overhead.
- Pagination - Implements physical pagination by appending limit and offset clauses to retrieve specific record subsets.
- SQL Dialect Adapters - Employs database-specific dialect adapters to ensure correct pagination syntax across different database vendors.
- SQL Persistence Frameworks - Extends the MyBatis persistence framework to provide runtime SQL modification and optimized data retrieval.
- SQL Interceptors - Uses a MyBatis interceptor chain to modify SQL queries at runtime before they are sent to the database.
- Data Set Windowing - Implements page-based data retrieval to enable efficient record navigation in user interfaces.
- Record Counting - Provides automatic generation and execution of count queries to determine the total number of records for pagination.
- Query Optimizations - Optimizes performance by limiting the amount of data fetched from the database during large record requests.
