Because the class you are using for POST request is VerifyLoginDto and the response type of this POST request is VerifyLoginRespDto.

The VerifyLoginRespDto must have property accessToken which is mapped to access_token.

NOTE : Please DON'T USE property name like this private String access_token;. You should follow camel case , because java and Spring follow this very sensitively. All the bean will be created according to camel case only.
