[FIXED] Provider ID must be specified for oauth2 client?

Issue

I am trying setting up a oauth2 client with spring-boot. I have this dependencies on my pom.xml:

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-oauth2-client</artifactId>
    </dependency>
    <dependency>
       <groupId>org.springframework.security</groupId>
       <artifactId>spring-security-oauth2-jose</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-tomcat</artifactId>
        <scope>provided</scope>
    </dependency>
</dependencies>

this configuration on my application.properties:

spring.security.oauth2.client.registration.mercadolivre.client-id=...
spring.security.oauth2.client.registration.mercadolivre.client-secret=...

and this security configuration class:

@Configuration
public class Security extends WebSecurityConfigurerAdapter {
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
         .anyRequest().authenticated()
         .and()
         .oauth2Login();
    }
}

whe I try run the application, give me this error:

What I am missing here?

Solution

You're missing the OAuth2 provider you'll be authorizing with, as described in the Spring reference.

Thesse are some of the properties you should provide:

spring.security.oauth2.client.registration.mercadolivre.provider=mercadolivre

spring.security.oauth2.client.provider.mercadolivre.authorization-uri=...
spring.security.oauth2.client.provider.mercadolivre.token-uri=...
