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...

CRUD Goes Even Easier With JPABuddy

Image
Create, Read, Update and Delete are the four basic operations of persistence storage. We can say these operations collectively as an acronym CRUD. These operations can be implemented in JPA. JPA is a standard for ORM. It is an API layer that maps Java objects to the database tables.  ORM stands for Object Relational Mapping. It converts data between incompatible type systems in object-oriented programming languages.  JPA Buddy is an IntelliJ IDEA plugin that helps developers work efficiently. JPA Buddy is a tool that is supposed to become your faithful coding assistant for projects with JPA and everything related. It is an advanced plugin for IntelliJ IDEA intended to simplify and accelerate everything related to JPA and surrounding mainstream technology. In fact, you can develop an entire CRUD application or a simple microservice by spending nearly zero time writing boilerplate code. The video demonstrates the features of JPA Buddy by creating a simple CRUD application from ...

Aspect Oriented Programming to trace the requests and responses to a REST method in Spring Boot.

Image
  Aspect Oriented Programming ( AOP ) is one of the key feature of Spring framework. AOP is similar to OOPS concept where it breaks code into multiple reusable modules. AOP provides the capability to dynamically add module at runtime. This is like injecting complete module(logging, cahcing, etc ) in Spring framework dynamically. Logging, caching, security, monitoring, etc. are some of the examples cross cutting concern from AOP. At any point of time there modules can be added dynamically. Spring AOP has interceptors which can intercept application and its methods. This is to perform some extra action at the time of property initiation, method initialization or destroy. Let's try it to create a custom annotation to trace the requests and responses to a REST method in Spring Boot At first you we need to use spring-boot-starter-web and spring-boot-starter-aop dependencies to make it work. STEP1 : An interface with the annotation name @Traceable Now , in whichever method you add the...
