I am trying to implement Spring security using google's oauth server. Application is very simple.

application.property has oauth configuration :
security.oauth2.client.id=xxxx.apps.googleusercontent.com
security.oauth2.client.client-secret=XXYYXXX
security.oauth2.client.access-token-uri=https://www.googleapis.com/oauth2/v4/token
security.oauth2.client.user-authorization-uri=https://accounts.google.com/o/oauth2/v2/auth
security.oauth2.client.token-name=oauth_token
security.oauth2.client.authentication-scheme=query
security.oauth2.client.client-authentication-scheme=form
security.oauth2.client.scope=profile email
security.oauth2.resource.user-info-uri=https://www.googleapis.com/oauth2/v3/userinfo
security.oauth2.resource.prefer-token-info=false
Then implemented basic websecurity :
package com.example.blog;
import org.springframework.boot.autoconfigure.security.oauth2.client.EnableOAuth2Sso;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
@Configuration
@EnableOAuth2Sso
public class WebSecurity extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception
{
http.csrf().disable()
.antMatcher("/**").authorizeRequests()
.antMatchers("/", "/index.html").permitAll()
.anyRequest().authenticated();
}
}
index.html file is very basic :
<!DOCTYPE html>
<html>
<head>
<meta charset="ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
<a href="user"> Google Login</a>
</body>
</html>
Main application class :
package com.example.blog;
import java.security.Principal;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
@SpringBootApplication
@RestController
public class GoogleOAuthLogin4Application {
public static void main(String[] args) {
SpringApplication.run(GoogleOAuthLogin4Application.class, args);
}
@GetMapping("/user")
public Principal get(Principal p)
{
return p;
}
}
After starting the server, when I hit http://localhost:8080 it loads index.html. When I click the link it shows following error page :
Server logs are as follows : UserRedirectRequiredException: A redirect is required to get the users approval
2018-07-24 23:15:01.174 ERROR 13452 --- [nio-8080-exec-5] o.a.c.c.C.[.[.[/].[dispatcherServlet] : Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception

I spent lot of time and tried to find the solution but i did not succeeded. But I found similar unanswered issues here :
1) Spring Security Facebook Oauth2 redirected too many times 2) Spring Boot UserRedirectRequiredException- A redirect is required to get the users approval
So I believe that lot of people are facing same issue. It would be of great help to me and many others if you can help. Thanks in advance.
There is a problem with your application.properties file code for Oauth2
Use below properties same as here means copy and paste in your application properties file and put your client id and secret key ,so it will work fine..try once
security.oauth2.client.clientId= ****Your ClientId **********************
security.oauth2.client.clientSecret= ****Your Secret ********************
security.oauth2.client.accessTokenUri = https://www.googleapis.com/oauth2/v3/token
security.oauth2.client.userAuthorizationUri = https://accounts.google.com/o/oauth2/auth
security.oauth2.client.tokenName = oauth_token
security.oauth2.client.authenticationScheme = query
security.oauth2.client.clientAuthenticationScheme = form
security.oauth2.client.scope = profile email
security.oauth2.resource.userInfoUri = https://www.googleapis.com/userinfo/v2/me
security.oauth2.resource.preferTokenInfo = false
