如何禁用特定URL的安全性以在安全4 xml配置中检索访问令牌

我正在开发一些休息应用程序，并且在弹簧安全性配置方面存在问题。

在我的其他应用程序中帮助我获取spring security 4的xml配置。

    <constructor-arg name="authenticationSuccessHandler">

    </constructor-arg>
</bean>

当我向/ rest / login发送用户名和密码时，我在CustomTokenAuthenticationFilter中捕获并且身份验证失败。如何配置我的xml到/ rest / login请求没有过滤和其他/ rest / **带过滤？

这是我的web.xml：

public class CustomTokenAuthenticationFilter extends AbstractAuthenticationProcessingFilter {

private static final Logger logger = LoggerFactory.getLogger(CustomTokenAuthenticationFilter.class);
private String excludedUrl;

public CustomTokenAuthenticationFilter(String excludedUrl, String defaultFilterProcessesUrl, AuthenticationManager authenticationManager, AuthenticationSuccessHandler authenticationSuccessHandler) {
    super(defaultFilterProcessesUrl);
    this.excludedUrl = excludedUrl;
    super.setRequiresAuthenticationRequestMatcher(new AntPathRequestMatcher(defaultFilterProcessesUrl));
    setAuthenticationManager(authenticationManager);
    setAuthenticationSuccessHandler(authenticationSuccessHandler);
}

public final String HEADER_SECURITY_TOKEN = "X-CustomToken";


/**
 * Attempt to authenticate request - basically just pass over to another method to authenticate request headers
 */
@Override
public Authentication attemptAuthentication(HttpServletRequest request, HttpServletResponse response) throws AuthenticationException, IOException, ServletException {
    String token = request.getHeader(HEADER_SECURITY_TOKEN);
    logger.info("token found:" + token);
    AbstractAuthenticationToken userAuthenticationToken = authUserByToken(token);
    if (userAuthenticationToken == null)
        throw new AuthenticationServiceException(MessageFormat.format("Error | {0}", "Bad Token"));


    return userAuthenticationToken;
}


/**

 */
private AbstractAuthenticationToken authUserByToken(String token) {
    if (token == null) {
        return null;
    }
    AbstractAuthenticationToken authToken = null;//todo
    try {
        return authToken;
    } catch (Exception e) {
        logger.error("Authenticate user by token error: ", e);
    }
    return authToken;
}

@Override
public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException {
    if (((HttpServletRequest) req).getRequestURI().endsWith(excludedUrl)) {
        chain.doFilter(req, res);
    } else {
        super.doFilter(req, res, chain);
    }
}
}

这是日志，当我发送请求时：

您可以在url中添加对customTokenAuthenticationFilter的检查，并在目标为/rest/login的情况下绕过过滤规则。 考虑这个例子：

    @Override
    protected final void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) throws ServletException,
                    IOException {
        if (!request.getRequestURL().toString().endsWith("rest/login")) { 
            ... apply filtering logic...
        }
        filterChain.doFilter(request, response);
    }
