ng-security | A security module for AngularJS | Frontend Framework library

I'm trying to get all information from Database inside a rest API in Sprint Boot, but I got the following error. I think Spring Boot doesn't recognize the Repository file I've created.

InstallationsRestController.java

I got the task to implement jwks on the project. On our project, we have implemented a token validation check with oauth2. We use a jks format certificate to obtain a public key. the private key is not used in our project, since we need to check the validity of the token. Our goal is to get rid of the .jks file. There are too few resources for jwks and therefore some points are not clear. If I understand correctly, then jwks mean that there is a jwks.json file in the resources with keys inside, which we select by kid from the token header. Based on the documentation, it is not clear what kind of file it is and how it is loaded for checking by kid, that is, at what moment it happens.Does anyone have a project that can be used as an example? thanks in advance

Sorry folks, this may be a newb question. I'm a little lost.

My Spring-boot environment provides me with keycloak for client authorization, it gives me these.

I am updating the my existing springboot project from 2.1.4 -> 2.3.11

The exiting code of class which extends WebSecurityConfigurerAdapter is as below

i'm using spring security with keycloak and if i do a request on a specific endpoint with an invalid token, it looks like the token validation is done 2 times, i've also tried to implement my own authentication provider which uses the logic of the keycloak authentication provider and overrided the BearerTokenRequestAuthenticator which does the token validation but it still does the same thing..i'm not sure if maybe the problem comes from some sort of bean definitions Here are same logs where you can see that the string "Verifying access_token" appears 2 times.

I am trying to run a project in Java and came across the following issues:

We have a spring-security filter chain as below where we provide the list of filters for each url pattern in the applicationContext.xml

I am desperately trying to migrate a Spring MVC 4.3.4.RELEASE application with Hibernate 4.3.8.Final to the latest version of Spring Boot, i.e. Spring Boot 2.5

The idea is to turn it into a Restful API and to drop all views.

Note : I did not create a custom configuration on the new spring-boot project.

My architecture looks like :

1. The controller
2. The DTO
3. The service
4. The DAO
5. The entity

Here is my pom.xml file :

Firstly: Yes, i know there's lots of this question already asked but no one really helped me much.

Secondly:

-I've tried making a simple Auth with my username+password from MySQL credentials into the Postman but didn't worked

I've tried to remove the cookies from postman and that did not work.

link where i got the idea: youtube link for this crud web app

I'm trying to develop an simple CRUD web app with Spring Boot, Lombok, JPA and Hibernate, MySQL. Everytime i try to make a POST request into Postman it doesn't give me anything(401 Unathorized), as shown here:

It only gives me "401 Unauthorized".

Of course when i run the project it gives me the DB shown in MYSQL

Here's the project content:(That YML file has nothing in it)

Here's some code:
