Mybatis Plus
MyBatis-Plus is a persistence framework extension for Java that simplifies data access by reducing boilerplate code. It provides a toolkit for automating common database operations, utilizing dynamic query wrappers and a system for automated CRUD generation.
The project distinguishes itself through a code generation system that produces mapper, model, service, and controller layers based on database metadata. It also implements a security layer that prevents SQL injection through input sanitization and blocks dangerous global update or delete operations to prevent accidental data loss.
The framework covers broad capability areas including database pagination management, strategy-based primary key generation, and an ActiveRecord pattern for executing operations directly within entity classes. It additionally provides tools for query performance analysis to identify and resolve slow database queries.
Features
- Java Persistence Toolkits - Provides a comprehensive set of tools for Java applications to handle database pagination, primary key generation, and ActiveRecord patterns.
- CRUD Interfaces - Provides a set of built-in mappers and services for performing automated create, read, update, and delete tasks.
- Fluent Query Builders - Uses lambda-based object wrappers to dynamically generate SQL WHERE clauses without manual XML or string concatenations.
- Persistence Frameworks - Extends the MyBatis framework to simplify data access through automated CRUD and dynamic query generation.
- Persistence Layers - Simplifies the creation of Java data access layers by reducing manual SQL and boilerplate code.
- Query Condition Builders - Offers a mechanism for constructing complex SQL WHERE clauses and filtering criteria using lambda expressions.
- SQL Query Builders - Provides lambda-based object wrappers to dynamically construct SQL queries without writing manual SQL strings.
- ActiveRecord Patterns - Implements the ActiveRecord pattern by integrating data access logic directly into entity models through base classes.
- Dangerous Operation Guards - Intercepts and blocks global update or delete actions that lack specific constraints to prevent accidental data loss.
- Unique Identifier Generators - Implements various strategies to automatically create unique record identifiers during the data insertion process.
- Distributed Identifier Generators - Provides swappable primary key generators, including snowflake and distributed identifiers, for diverse database environments.
- Pagination - Automatically slices large result sets into pages to improve application performance and user experience.
- Query Performance Monitors - Includes tools to output executed SQL statements and their processing times to identify and resolve slow queries.
- SQL Interceptors - Allows modification of executed SQL statements at runtime to inject pagination and safety constraints via a plugin system.
- Boilerplate Generators - Includes a command-line utility that scaffolds mapper, model, service, and controller layer code.
- Source Generation Templates - Uses predefined templates to automate the generation of boilerplate source files for multiple application layers.
- Database Injection Prevention - Provides automated cleaning and parameterization of database queries to protect against SQL injection vulnerabilities.
- Security Hardening and Protection - Protects applications from SQL injection and prevents accidental bulk data loss through global operation blocking.
- SQL Injection Prevention - Implements a security layer that filters and sanitizes inputs to prevent SQL injection attacks within the persistence layer.
- ORM - Enhanced toolkit for simplifying MyBatis development.
