In the previous blog post, we discussed how to configure a simple OAuth2 authentication. However, our implementation has a major flaw in it: we are using an in-memory token store.
In-Memory token stores should be used only during development or whether your application has a single server, as you can’t easily share them between nodes and, in case of a server restart, you will lose all access tokens in it.
Spring-security-oauth2 already has built-in support for JDBC and JWT. However, if you need to save your tokens somewhere else, you have to create your own spring security token store. Unfortunately, implementing such a thing is not a trivial task, and I hope the following recipe will save you a couple hours of work.
Let’s start by creating the two entities responsible for storing your access and refresh token, and their respective repositories:

Note that OAuth2Authentication is an interface, so I have no option other than serializing the object to store it in the database. Here is the class responsible for serializing/deserializing it:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 |
공공의 class SerializableObjectConverter { 공공의 static 문자열 serialize(OAuth2Authentication object) { 시도하다 { byte[] bytes = SerializationUtils.serialize(object); 반환 베이스64.encodeBase64String(bytes); } catch(Exception e) { e.스택 추적 출력(); throw e; } } 공공의 static OAuth2Authentication deserialize(문자열 encodedObject) { 시도하다 { byte[] bytes = 베이스64.decodeBase64(encodedObject); 반환 (OAuth2Authentication) SerializationUtils.deserialize(bytes); } catch(Exception e) { e.스택 추적 출력(); throw e; } } |
Now, we can finally create our custom spring oauth2 token store. To do that, all we need is to implement the long list of methods of the org.springframework.security.oauth2.provider.token.TokenStore:

Finally, we can slightly change our SecurityConfig class, which we have created in the previous article. It will return now an instance of CouchbaseTokenStore instead of InMemoryTokenStore:
|
1 2 3 4 5 6 7 8 9 10 11 |
@Autowired private CouchbaseAccessTokenRepository couchbaseAccessTokenRepository; @Autowired private CouchbaseRefreshTokenRepository couchbaseRefreshTokenRepository; @Bean 공공의 TokenStore tokenStore() { 반환 새로운 CouchbaseTokenStore(couchbaseAccessTokenRepository, couchbaseRefreshTokenRepository); } |
Here is the complete version of the SecurityConfig class:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 |
@Configuration @EnableWebMvc 공공의 class SecurityConfig 확장합니다 WebSecurityConfigurerAdapter { @Autowired private CustomUserDetailsService customUserDetailsService; @Autowired private CouchbaseAccessTokenRepository couchbaseAccessTokenRepository; @Autowired private CouchbaseRefreshTokenRepository couchbaseRefreshTokenRepository; @Autowired 공공의 무효 globalUserDetails(AuthenticationManagerBuilder auth) throws Exception { auth.userDetailsService(customUserDetailsService) .passwordEncoder(encoder()); } @Override 공공의 무효 configure( WebSecurity web ) throws Exception { web.ignoring().antMatchers( HttpMethod.OPTIONS, “/**” ); } @Override protected 무효 configure(HttpSecurity http) throws Exception { http .csrf().disable() .authorizeRequests() .antMatchers(“/oauth/token”).permitAll() .antMatchers(“/api-docs/**”).permitAll() .anyRequest().authenticated() .그리고().anonymous().disable(); } @Bean 공공의 TokenStore tokenStore() { 반환 새로운 CouchbaseTokenStore(couchbaseAccessTokenRepository, couchbaseRefreshTokenRepository); } @Bean 공공의 PasswordEncoder encoder(){ 반환 NoOpPasswordEncoder.getInstance(); } @Bean 공공의 FilterRegistrationBean corsFilter() { UrlBasedCorsConfigurationSource source = 새로운 UrlBasedCorsConfigurationSource(); CorsConfiguration 설정 = 새로운 CorsConfiguration(); 설정.setAllowCredentials(true); 설정.addAllowedOrigin(“*”); 설정.addAllowedHeader(“*”); 설정.addAllowedMethod(“*”); source.registerCorsConfiguration(“/**”, 설정); FilterRegistrationBean bean = 새로운 FilterRegistrationBean(새로운 CorsFilter(source)); bean.setOrder(0); 반환 bean; } @Bean @Override 공공의 AuthenticationManager authenticationManagerBean() throws Exception { 반환 super.authenticationManagerBean(); } } |
Well Done! That is all we had to do.
Your access token will look like the following in your database:

Hi Denis,
First of all, thank you for the very brief but concise tutorial. Although it is over a year, it is well explained, and I must acknowledge that you are an excellent teacher.
Please, I have one question and a request to make. Is it possible to add JWT to this implementation OAuth2, and if yes,can you please provide a guide?
Waiting for a reply.
Thank you so much.
