Unable to resolve Configuration with the provided Issuer of "/oauth2/default"

I’m using spring boot with vuejs, I’ve added the okta-vue sdk and its working fine. tried configuring the resource server but it kept throwing the below error;

Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'securityConfiguration': Unsatisfied dependency expressed through method 'setContentNegotationStrategy' parameter 0; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'org.springframework.boot.autoconfigure.web.servlet

what I did:

  1. Added Okta dependency

      <dependency>
             <groupId>com.okta.spring</groupId>
             <artifactId>okta-spring-boot-starter</artifactId>
             <version>1.4.0</version>
         </dependency>
    

then added

    @EnableWebSecurity
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
                .anyRequest().authenticated()
                .and()
                .oauth2ResourceServer().jwt();
    }
}

added the issuer and client id in the properties:

okta.oauth2.issuer=https:///oauth2/default
okta.oauth2.client-id=
****

ERRORS:

Exception in thread "task-2" org.springframework.beans.factory.BeanCreationNotAllowedException: Error creating bean with name 'delegatingApplicationListener': Singleton bean creation not allowed while singletons of this factory are in destruction (Do not request a bean from a BeanFactory in a destroy method implementation!)

  1. Added both okta spring boot starter and

    org.springframework.security.oauth.boot spring-security-oauth2-autoconfigure 2.3.3.RELEASE

then added the
@EnableResourceServer annotation to my class.

also, added corsfilter.

but i keep getting the same error.

what am i missing, someone should please help.

Ok, I changed my JDK from java 8 to 11 and it’s now working fine.

@chairmo Thanks for the update . It sounds like the issue is gone after you upgrade JDK.
