我想弹出一个自定义“/login”端点，该端点检查oauth访问令牌，如果该令牌已验证，则启动会话。
这是我的登录控制器：

@Autowired
private AuthenticationManager authManager;

private final CsrfTokenRepository csrfTokenRepository;

public LoginController() {
    this.csrfTokenRepository = new HttpSessionCsrfTokenRepository();
}

@PostMapping("/login")
public String login(HttpServletRequest req, @RequestBody String accessToken) {
    System.out.println("login");
    try {

        NimbusJwtDecoder jwtDecoder = NimbusJwtDecoder.withJwkSetUri("http://myauthserver/auth/realms/infraserv/protocol/openid-connect/certs").build();
        Jwt jwt = jwtDecoder.decode(accessToken);
        JwtAuthenticationToken authReq = new JwtAuthenticationToken(jwt);
        System.out.println("authManager = " + authManager.getClass());
        Authentication auth = authManager.authenticate(authReq);
        SecurityContext sc = SecurityContextHolder.getContext();
        sc.setAuthentication(auth);
        HttpSession session = req.getSession(true);
        session.setAttribute(SPRING_SECURITY_CONTEXT_KEY, sc);
        return "Authenticated :-)";
    } catch (IllegalArgumentException e) {
        // TODO log
        System.err.println(e.getMessage());
        return "Not Authenticated!!";
    }
}

这是我的网站安全配置：

@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        HttpSessionCsrfTokenRepository csrfTokenRepository = new HttpSessionCsrfTokenRepository();
        http
                .csrf().csrfTokenRepository(csrfTokenRepository)
                .and()
                .authorizeRequests()
                .antMatchers(HttpMethod.POST,"/login").permitAll()
                .antMatchers(HttpMethod.GET,"/csrf").permitAll()
                .anyRequest().authenticated();
    }

    @Bean
    @Override
    public AuthenticationManager authenticationManager() throws Exception {
        return super.authenticationManagerBean();
    }
}

问题是，如果调用“/login/method，就会得到一个StackOverflower错误。

我已经找到了这个，并尝试了所有的组合 authenticationManager 及 authenticationManagerBean 但结果都是一样的。
