Persism is a light weight, auto discovery, autoconfiguration, and convention over configuration ORM (Object Relational Mapping) library for Java 17 or later.
Persism uses a standard Connection object so all you need to do is create the Session object passing in the Connection.
This is free and open source software.
Key Features
- Supports most common databases – Derby, Firebird, H2, HSQLDB, Informix, MSAccess, MSSQL, MySQL/MariaDB, Oracle (12+), PostgreSQL, SQLite.
- No special configuration. Drop the JAR into your project and go.
- Small API.
- Auto-Discovery – create a table, write a JavaBean, run a query. Persism uses simple mapping rules to find your table and column names and only requires an annotation where something is outside convention.
- Small – About 100k is size and has no dependencies.
