PageHelper is a MyBatis plugin that adds pagination support to database queries.
The plugin solves the problem of implementing pagination in MyBatis applications by intercepting query execution and automatically rewriting SQL statements to add physical pagination logic specific to the target database. It works as an executor interceptor that modifies queries before they reach the database, supporting both single-table and multi-table pagination scenarios. The tool handles database-specific SQL syntax variations through a dialect system, with built-in support for multiple databases and the ability to configure custom dialects for unsupported systems.
Developers should choose this plugin if they are building MyBatis applications that require pagination functionality. It suits projects of any scale that need to paginate query results without manually writing database-specific SQL. The plugin integrates directly into the MyBatis execution pipeline and requires only the PageHelper JAR and jsqlparser JAR on the classpath. Spring Boot users can use the dedicated Spring Boot starter for simplified configuration.
The project maintains active engagement with its user base through comprehensive documentation covering usage patterns, configuration options, and edge cases. Development follows the MyBatis QueryInterceptor specification, ensuring compatibility with the broader MyBatis ecosystem. The tool supports multiple Java versions across different release lines, with recent versions targeting Java 8 and later while maintaining support for older Java versions in earlier release branches.
