Easy Rules is a lightweight Java rules engine that provides a Rule abstraction with conditions and actions plus a RulesEngine API to evaluate and execute them. It supports POJO-based annotation rules, composite rules, and expression languages like MVEL, SpEL, and JEXL.
Use cases
- evaluate business rules in a java application
- build a lightweight rules engine without drools
- define conditional logic with annotations on pojos
- compose complex rules from simple ones
- express rules with mvel or spel expressions
- implement if-then decision logic declaratively
When to choose
- you need a simple, lightweight rules engine in Java with minimal learning curve
- you want POJO-based rules with annotation or fluent API definitions
- you prefer expression-language rules (MVEL, SpEL, JEXL) over heavyweight engines like Drools
When to avoid
- you need a project under active development - it is in maintenance mode since December 2020 with only bug fixes
- you need advanced rules engine features like RETE networks, inference chaining, or rule flows
- you are not on the JVM
