generateEncodedTokenAsJWTAndDecodeIt
Here Claims is a process of reading or parsing JWT details by providing two inputs : Token & Secret Key In order to implement the POC(Proof Of Concept) on ‘How to generate & read Claims back’, we should think of finding a JAVA API for JWT. Undoubtedly, we already have jjwt.jar to make it possible. Now let’s create a POC to implement our functionality step by step.

REST_INVOICE_PROJECT
In this project, we create a Spring Boot REST application that incorporates industry level project design. We are developing CRUD (Create, Retrieve, Update, Delete) operations that can be used by any other even non-java application and write bug free CRUD operations, including exceptions & exception handlers. Equally important, we are used several annotations @RestController, @RequestMapping, @GetMapping, @PostMapping, @PutMapping, @DeleteMapping, @PatchMapping, @Modifying, @Query, @Transactional, @RestControllerAdvice, @ExceptionHandler, @ControllerAdvice, @ResponseBody, @RequestBody, @PathVariable, @Data, @NoArgsConstructor, @AllArgsConstructor, @Entity, @Component, @Service, @Autowired. We are worked with Spring Boot Data JPA repository interface and write modular & reusable code. Moreover, we are implementing dynamic code with minimal changes, keeping future change requests in mind, and we are developing an integration layer to get interoperability. And we are integrating swagger UI to test REST Application.
SpringBoot_MVC_CRUD_APP
Let’s assume we have to develop an Invoice Processing Application. As the application name suggests, we must have an Invoice entity in this application. we will develop CRUD operations for Invoice as an entity.
springSecurityInMemoryV1
In this project we consider an application of a small organization where we have three roles : EMPLOYEE, MANAGER and ADMIN. In addition, we will have role based restricted access to some particular pages. On the one hand, some pages will be accessible to multiple roles and on the other hand some with no restrictions(accessible to all roles). Moreover, we will use thymeleaf to create pages. Additionally, we will have a controller class to serve the user’s request. this application is developped by a code Before Spring Security 5.7.0
