How to fix infinite redirect when using Spring Oauth2?

Question

Java

I'm setting up OAuth2 through spring boot 2, but after entering my login and password, I'm constantly being redirected to the login form. In the http client, I traced the cap, but I did not see an error that would indicate that the password was not correct.
1) localhost:4002/hello/user [GET]
2) localhost:4002/login [GET]
3) localhost:5000/oauth/authorize?client_id=browser&r... [GET]
4) localhost:5000/login [GET] ]
5) localhost:5000/login [POST] form username=bleser;password=123
6) localhost:5000/oauth/authorize?client_id=browser&r... [GET]
7) localhost:4002/login?code=GnffIl&state= c7jCbQ
8) item 2
