spring-security-oauth2

I am trying to implement the above architecture in the workflow with Spring Boot. Web client makes a request to Resource Server (Microservices Endpoints) through Zuul Proxy. Zuul Proxy redirects to oauth2 server for authentication. Oauth2 redirects to Zuul Proxy if the request is authenticated or not. If not authenticated, Zuul redirects Web client with an unauthenticated response. If Authenticated, Zull proxy redirects to the requested microservice endpoint. Microservice endpoint checks if the user is authorized (user level access) to access the resource or not. Microservice also could make

I am new to Spring Boot, and I am trying to configure OAuth 2.0. The problem I am having at this moment is that I keep getting the following message when I attempt to request for an access token: { "error": "invalid_grant", "error_description": "Bad credentials" } The error message in the Spring Boot console says that the user cannot be found. : Authentication attempt using org.springframework.security.authentication.dao.DaoAuthenticationProvider : User 'stromero' not found : Returning cached instance of singleton bean 'authenticationAuditListener' I have implemented a custom user that has

I have implemented oAuth2 with spring security and it is working fine for me. But Now I want to create user token from back-end manually without password. Because I have only username of user. Can any one help me. Got Answer!!!

I am doing an in-depth study of Spring OAuth, and I found some conflicting information. Can someone please clarify? Specifically, this tutorial states that the /oauth/token endpoint handles the username and password before granting a refresh token to the client app. By contrast, the Spring OAuth Developer Guide mentions the /oauth/authorize and /oauth/token endpoints, but yet does not get specific about how they work. Does the /oauth/authorize do 100% of the username/password/nOtherFactors check and then signal the /oauth/token endpoint to send a refresh token to the client, so that the client

I'm using Spring Oauth2 and Spring Pre-post Annotations With Spring-boot I Have a service class MyService . one of MyService methods is: @PreAuthorize("#id.equals(authentication.principal.id)") public SomeResponse getExampleResponse(String id){...} can i control in some manner the json that is returned by the caller Controller? the json that is returned by default is: {error : "access_denied" , error_message: ".."} I Want to be able to control the error_message param. I'm looking for something similar to: @PreAuthorize(value ="#id.equals(authentication.principal.id)", onError ="throw new
