Description

This project is the PoC of injecting AspectJ aspects into already built Spring Boot application through Java agent

How to run

Create demo application with Spring Initializr

Build this project and modify starting script of your Spring Boot application like that:

  1. #!/usr/bin/env bash
  3. java -javaagent:aspectjweaver-1.9.7.jar \
  4.      -javaagent:spring-aop-java-agent-inject-1.0.0.jar \
  5.      -jar demo-1.0.0.jar

You should see aspect execution in the log just before main() method:
