拉勾教育keycloak自定义redirect_uri

在使用keycloak集成springboot的过程中，对于需要授权访问的接口，它会跳到keycloak里进行登录，之前有个redirect_uri,登录成功后会跳回本客户端，而这个地址默认没有修改的地方，需要我们手动开发，这块不是很方便。拉勾IT课小编为大家分解
自定义redirect_uri
一 重写BeanPostProcessor来实现

@Component
public class KeycloackAuthenticationProcessingFilterPostProcessor implements BeanPostProcessor {

  private static final Logger logger = LoggerFactory.getLogger(KeycloackAuthenticationProcessingFilterPostProcessor.class);

  private void process(KeycloakAuthenticationProcessingFilter filter) {
    filter.setRequestAuthenticatorFactory(new SpringSecurityRequestAuthenticatorFactory() {
        @Override
        public RequestAuthenticator createRequestAuthenticator(HttpFacade facade, HttpServletRequest request, KeycloakDeployment deployment, AdapterTokenStore tokenStore, int sslRedirectPort) {
          return new SpringSecurityRequestAuthenticator(facade, request, deployment, tokenStore, sslRedirectPort) {

            @Override
            protected OAuthRequestAuthenticator createOAuthAuthenticator() {
                return new OAuthRequestAuthenticator(this, facade, deployment, sslRedirectPort, tokenStore) {

                  @Override
                  protected String getRequestUrl() {
                    return "http://localhost:8081/callback";
                  }
                };
            }

          };
        }
    });
  }

  @Override
  public Object postProcessAfterInitialization(Object bean, String beanName) throws BeansException {
    if (bean instanceof KeycloakAuthenticationProcessingFilter) {
        l***("Injecting Custom handler...");
        process(((KeycloakAuthenticationProcessingFilter) bean));
    }
    return bean;
  }

二 在没有授权时，直接跳到 授权系统，然后观察地址上redirect_uri已经发生变化了
