Spring Boot OAuth2 authentication with login form - spring-boot

Question

i am new to Spring Boot and OAuth2 , i found ressources on github and trying to practice to understand more the architecture and flows, so i have the configuration as follow :
OAuth2Configuration.java
#Configuration
public class OAuth2Configuration {
#Configuration
#EnableResourceServer
protected static class ResourceServerConfiguration extends ResourceServerConfigurerAdapter {
#Autowired
private CustomAuthenticationEntryPoint customAuthenticationEntryPoint;
#Autowired
private CustomLogoutSuccessHandler customLogoutSuccessHandler;
#Override
public void configure(HttpSecurity http) throws Exception {
http
.exceptionHandling()
.authenticationEntryPoint(customAuthenticationEntryPoint)
.and()
.logout()
.logoutUrl("/oauth/logout")
.logoutSuccessHandler(customLogoutSuccessHandler)
.and()
.csrf()
.requireCsrfProtectionMatcher(new AntPathRequestMatcher("/oauth/authorize"))
.disable()
.headers()
.frameOptions().disable()
.sessionManagement()
.sessionCreationPolicy(SessionCreationPolicy.STATELESS)
.and()
.authorizeRequests()
.antMatchers("/secure/**", "/person/**", "/product/**").authenticated()
.antMatchers(HttpMethod.GET, "/user/**").authenticated()
.antMatchers(HttpMethod.PUT, "/user/**").authenticated()
.antMatchers(HttpMethod.DELETE, "/user/**").authenticated()
.antMatchers(HttpMethod.POST, "/user").permitAll();
}
}
#Configuration
#EnableAuthorizationServer
protected static class AuthorizationServerConfiguration extends AuthorizationServerConfigurerAdapter implements EnvironmentAware {
private static final String ENV_OAUTH = "authentication.oauth.";
private static final String PROP_CLIENTID = "clientid";
private static final String PROP_SECRET = "secret";
private static final String PROP_TOKEN_VALIDITY_SECONDS = "tokenValidityInSeconds";
private RelaxedPropertyResolver propertyResolver;
#Autowired
private DataSource dataSource;
#Bean
public TokenStore tokenStore() {
return new JdbcTokenStore(dataSource);
}
#Autowired
#Qualifier("authenticationManagerBean")
private AuthenticationManager authenticationManager;
#Override
public void configure(AuthorizationServerEndpointsConfigurer endpoints)
throws Exception {
endpoints
.tokenStore(tokenStore())
.authenticationManager(authenticationManager);
}
#Override
public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
clients
.inMemory()
.withClient(propertyResolver.getProperty(PROP_CLIENTID))
.scopes("read", "write")
.authorities(Authorities.ROLE_ADMIN.name(), Authorities.ROLE_USER.name())
.authorizedGrantTypes("password", "refresh_token")
.secret(propertyResolver.getProperty(PROP_SECRET))
.redirectUris("http://localhost:8080/login")
.accessTokenValiditySeconds(propertyResolver.getProperty(PROP_TOKEN_VALIDITY_SECONDS, Integer.class, 1800));
}
#Override
public void setEnvironment(Environment environment) {
this.propertyResolver = new RelaxedPropertyResolver(environment, ENV_OAUTH);
}
}
}
SecurityConfiguration.java
#Configuration
#EnableWebSecurity
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {
#Autowired
private UserDetailsService userDetailsService;
#Bean
public PasswordEncoder passwordEncoder() {
// Define the type of encode
return new BCryptPasswordEncoder();
}
#Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
auth
.userDetailsService(userDetailsService)
.passwordEncoder(passwordEncoder());
}
#Override
public void configure(WebSecurity web) throws Exception {
web
.ignoring()
//.antMatchers("/h2console/**")
.antMatchers("/register")
.antMatchers("/activate")
.antMatchers("/lostpassword")
.antMatchers("/resetpassword")
//.antMatchers("/hello")
.antMatchers("/person")
.antMatchers("/product");
}
#Override
#Bean
public AuthenticationManager authenticationManagerBean() throws Exception {
return super.authenticationManagerBean();
}
#EnableGlobalMethodSecurity(prePostEnabled = true, jsr250Enabled = true)
private static class GlobalSecurityConfiguration extends GlobalMethodSecurityConfiguration {
#Override
protected MethodSecurityExpressionHandler createExpressionHandler() {
return new OAuth2MethodSecurityExpressionHandler();
}
}
}
CustomAuthenticationEntryPoint.java
#Component
public class CustomAuthenticationEntryPoint implements AuthenticationEntryPoint {
private final Logger log = LoggerFactory.getLogger(CustomAuthenticationEntryPoint.class);
public void commence(HttpServletRequest request,
HttpServletResponse response,
AuthenticationException ae) throws IOException, ServletException {
log.info("Pre-authenticated entry point called. Rejecting access");
response.sendError(HttpServletResponse.SC_UNAUTHORIZED, "Access Denied");
}
}
what i want to achieve is authenticate users using loging form on browser in order to access protected ressources , but i don't know how in this configuration.
example :
when i access to /product , it shows all products cos it's not secured , but /product/3 for example is protected so it shows a blank webpage with error access denied , i want to show loging form.
when
