Spring OAuth2 - There is no client authentication. Try adding an appropriate authentication filter

Question

We have an application which is using spring-security-oauth2:1.0. I was trying to change it to a newer version, spring-security-oauth2:2.0.7.RELEASE

Answer 1

The problem can be because of opening all requests. You should remove it.

 @Override
public void configure(WebSecurity web) throws Exception {
    web
            .ignoring()
            .antMatchers("/**");
}
