As a first step, a client must authenticates itself using a username and password, receiving a signed token (JWT) in exchange. First we need to introduce BCryptPasswordEncoder as a bean in to our application. UserDetails contains necessary information (such as: username, password, authorities) to build an Authentication object. html { JPA Many to Many example with Hibernate in Spring Boot, Unit Test: Here we only have BCryptPasswordEncoder as a custom bean but, we can use these type of configuration class to introduce any number of custom beans inside spring application. OncePerRequestFilter makes a single execution for each request to our API. It has one problem, when this server is restarted or shut down then this user is automatically logged out. You can look at UserDetailsService interface that has only one method: So we implement it and override loadUserByUsername() method. What is JWT?
