Need suggestion to use Interceptor for logging

[aanshu_2302]

Hi,

I am planning to use Interceptors to logging each method call in EJB. I have large no of EJB's say currently more than 100..

Does it makes sense to use Interceptor to wrtie logs for each methods or use normal Logging API such as log4j?

I want to know the performance benefits or implications for both.

Thanks.

Keeping aside performance considerations, what kind of logging do you expect from the interceptor? All it can do is perhaps log certain generic log messages like "entering method" kind of stuff. If you want real/detailed logging from the beans, then directly using the logger within the bean implementation is a better way to do it.

Yes. I was thinking of implementing so that I get proper logs before each EJB call that doSoemthing() called and then I could figure out the from the logs where some problem occured.

This was my scenario.

For detailed, logging of exception, I think loggers are better. I just wanted to seek opinion if anybody came across some benefits with Interceptors.

When should be use Interceptors?

1. For logging, business critical methods.?

2. Security authentication?

Any other use cases that you can suggest?

I've worked on projects that use the org.springframework.ejb.interceptor.SpringBeanAutowiringInterceptor to set up @Autowired annotations on EJBs.
