将Spring Security身份验证与Oauth2服务器集成

Question

我为Spring Boot（1.3.0）上托管的AngularJS应用程序提供了以下Web安全配置类：

@Configuration
@Order(SecurityProperties.ACCESS_OVERRIDE_ORDER)
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.httpBasic().and().authorizeRequests()
                .antMatchers("/index.html", "/", "/js/**", "/css/**", "/img/**", "/bower_components/**", "/templates/login/**",
                        "/fonts/**", "/user")
                .permitAll().anyRequest().authenticated().and()
                .addFilterAfter(new CsrfHeaderFilter(), CsrfFilter.class)
                .csrf().csrfTokenRepository(csrfTokenRepository()).and().logout().logoutSuccessUrl("/");

    }

     @Autowired
        public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
            auth.inMemoryAuthentication().withUser("myuser").password("password").roles("USER");
        }

    private CsrfTokenRepository csrfTokenRepository() {
        HttpSessionCsrfTokenRepository repository = new HttpSessionCsrfTokenRepository();
        repository.setHeaderName("X-XSRF-TOKEN");
        return repository;
    }
}

如何使用仅具有“refresh_token”和“password”授权类型的Oauth2服务器来替换configureGlobal方法进行身份验证？
