Spring Cloud Config Client not fetching config when Spring Security is active on Spring Cloud Config Server

Question

When I run spring cloud config server without spring security the service fetches the config without issue but when I activate Spring security it won't fetch the config files. It seems to throw a 401 http error. I have checked that the username and password is correct, I have also tried the user:password@url way of authenticating with the same issue.

If i access the url http://localhost:8888/service/default directly in browser and enter the username and password the configs are displayed.

Any help will be appreciated, I am not sure if there is an issue with my cloud config or my security config.

Spring Boot version: '2.2.4.RELEASE'
spring-cloud-config-server version: '2.2.1.RELEASE'
Build system: Gradle
Java 8

This config always fails, I tried adding it to existing services I had and it did not work so I created a new config server and a new client via the spring initializer on https://start.spring.io/ with the below config and still does not work.

Log when security is active:

config server application.yml file
github uri is obscured, connection to the private repo is not the issue.

server:
  port: 8888

spring:
  application:
    name: config-server
  security:
    user:
      name: 'root'
      password: '1234'
  cloud:
    config:
      server:
        git:
          uri: <github-uri>
          ignore-local-ssh-settings: false
          strict-host-key-checking: false
          private-key: 'classpath:resources/id_rsa'

service application.yml file

spring:
  application:
    name: service
  cloud:
    config:
      uri: http://localhost:8888
      username: 'root'
      password: '1234'
      fail-fast: true

The web security is very basic but below is the security config:

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    // Secure the endpoints with HTTP Basic authentication
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests().antMatchers("/**").fullyAuthenticated();
        http.httpBasic().and().exceptionHandling();
    }
}

For everyone who is following any outdated cloud tutorials:- from springboot 2.4 bootstrap starter dependency has to be added, to follow along the tutorial to use bootstrap.properties (bootstrap.yml) for external configuration.

<dependency>
 <groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-bootstrap</artifactId>
</dependency>

You should use bootstrap.yaml (not application.yaml) for the client app.

It works without security only because your client is using default config, which doesn't have username and password. When you enable security it returns 401 because default username and password are empty.

Awesome your answer worked. I am new to spring cloud so in the tutorials the bootsrap.yml was not mentioned. Adding a link to this answer for more info for anyone else that comes across this issue. https://stackoverflow.com/questions/32997352/what-is-the-difference-between-putting-a-property-on-application-yml-or-bootstra – Neco Horne Feb 21 '20 at 06:48
