MDC Logger

What is MDC?
- MDC stands for Mapped Diagnostic Context.
- It is a map which stores the context data of the particular thread where the context is running
Where do we use it ?
- For Jersey: ContainerRequestFilter, ContainerResponseFilter
- For Spring MVC : HttpServletRequest, HttpServletResponse
Why do we use it ?
- It helps you to distinguish inter-leaving logs from multiple sources.
- When we have multiple user-requests coming in for a given servlet, each request of an user is serviced using a thread. This leaves multiple users logging to the same log file and the log statements get inter-mixed.
- Now, to filter out logs of a particular user, we need to append the user-id to the log statements so that we can search them in the log file easily.
- An obvious way of logging, is to append the user-id in the log statements i.e. log.info(userId+” logged something “);
- A non-invasive way of logging is to use MDC.
- With MDC, you put the user-id in a context-map which is attached to the thread (of each user request) by the logger.

Using SOAP UI vs RestClient

I-Using RestClient tool:
II-Using SOAP UI tool:
- I have just uploaded TestCases for using SOAP UI. And, i have added GET/POST testCases,but not DELETE/PUT method.
- Dowload SOAP UI tool
- File/Import Project
- Hopefully, you enjoy.
