Spring Boot Security | Role-based Authorization with Example
In This example, Use the Spring Security to authorize users based on their roles for a Spring Boot application.
The credentials and roles are stored dynamically in H2 database(required query is as follows).
Spring Data JPA with Hibernate is used for the data access layer and Thymeleaf integration with Spring Security is used for the view layer.
Steps:
1. Dependencies – in pom.xml file
2. Make class - User and Role
3. Make interface UserRepository
4. Implement UserDetails and UserDetailsService
5. Configure authentication and authorization
