Spring AOP vs AspectJ
Considerations
- Compatibility with project
- Overhead
- How quickly can it be integrated
- Where can it be implemented
Concepts
| Term | Definition |
|---|---|
| Aspect | Standard / reusable code piece / feature |
| Joinpoint | Particular point of execution (method execution, constructor / field assignment) |
| Advice | Action taken by aspect in specific joinpoint |
| Pointcut | Regex that matches joinpoint |
| Weaving | process of linking aspects with targeted objects |
| Advised Object | Generated object after weaving |
Capabilities and Goals
| Spring AOP | Aspect J |
|---|---|
| Simple | More complete (but complicated) |
| Run-time weaving | Compile / Post-Compile / Load-time weaving |
| Better performance |
info
Compile-time weaving: (Source code, aspect) => woven class files
Post-compile (binary) weaving: Weave existing class files
Load-time weaving: Similar to post-compile, only done when loaded into JVM
