OAuth 2.0

• OAuth 2.0 is the industry-standard protocol for authorization. OAuth 2.0 focuses on client developer simplicity while providing specific authorization flows for web applications

When we are implementing OAuth 2.0 then there are three component

AuthenticationServer

ResourceOwnerUser

ResourceServer

In AuthenticationServer, we need to defend two config files

WebSecurityConfig.java

OAuth2AuthorizationServerConfig.java

In ResourceOwnerUser,

we need to create User and Roles classes with Many to Many relation and expose Api like UserResource.java

ResourceServer

Now final we need to create ResourceServer.

OAuthConfiguration.java

In controller we need to create end point by using @PreAuthorize

TestResource.java
