Debug Java Stream in Intellij Idea

Image
Stream is a very powerful feature. it allows you to take full advantage of modern multi-core architectures and lets you process data in a declarative way.  Unfortunately stream API may sometimes be difficult to debug. This happens because they require you to insert additional breakpoints and thoroughly analyze each transformation inside the stream.  IntelliJ IDEA provides a solution to this by letting you visualize what is going on in Java Stream operations. Just install plugin called “Java Stream Debugger”. Once you have enabled this plugin you can simply debug your code. This plugin will bring a trace icon (Trace Current Stream Chain button).   Trace Current Stream Chain button Once you click on that icon you get the visualization of your stream pipeline.  For every stream operation, we have got a dedicated tab. you have to switch to the relevant tab to understand what it is doing.

Logging Request and Response Body In Spring Boot

Image
  I recently read a Gain Java Knowledge article about logging Spring Boot Request and Response. I really like the idea so I decided to test it in practice. How to logging Spring Boot Request and Response? Request and response body for each endpoint we can print using Servlet Filter. Inside our controller class we will not log any statement but our filter class will log the request and response body for each API call. So this approach will reduce the lines of code and we don’t need to worry about to add log statements in each API to print Request and response body. The Filter class will be used to log requests and responses for each API. LoggingFilter class will extends OncePerRequestFilter class because this is Filter base class that aims to guarantee a single execution per request dispatch, on any servlet container. It provides a doFilterInternal method with HttpServletRequest and HttpServletResponse arguments. Conclusion: In my opinion, this is the best solution to log request...
