Extract Currently Logged in User information from JWT token using Spring Security

Question

I have implemented JWT and LDAP Authentication using Spring Security Oauth2. It seems to be working fine and I can login with my LDAP credentials.

Now, there is one req

Answer 1

In your REST Service, add the OAuth2Authentication Class as an argument

@RequestMapping(value = "/{id}/products", method = RequestMethod.POST)
    public ResourceResponse processProducts(OAuth2Authentication auth) {

Springboot will automatically map the logged-in user details to this object. Now, you can do the following to access the username

auth.getPrincipal().toString()
