Spring Security 3.2在HttpSecurity中设置authenticationEntryPoint无效（Java-Config）

Question

我想将spring安全配置从xml转换为java config。 几乎没有完成，最后一个问题是AuthenticationEntryPoint。 HttpSecurity中的设置将被忽略。

我使用Spring security 3.2.0.M2

Snipped of SecurityConfig.class

@Override
    protected void configure(HttpSecurity http) throws Exception {
        http
            .addFilterAfter(httpPayloadFilter(), ChannelProcessingFilter.class)
            .addFilterAfter(httpRestLoginFilter(), SecurityContextPersistenceFilter.class)
            .authorizeUrls()
                .antMatchers("/**").hasRole("USER")
                .antMatchers("/secure/clientident/**").hasRole("REQUESTVALID")
                .and()
            .httpBasic().authenticationEntryPoint(delegatingAuthenticationEntryPoint());
    }

@Bean
    public DelegatingAuthenticationEntryPoint delegatingAuthenticationEntryPoint() {

        ELRequestMatcher matcher = new ELRequestMatcher("hasHeader('user-agent', 'Mozilla') or " +
                "hasHeader('user-agent', 'Chromium') or " +
                "hasHeader('user-agent', 'Chrome') or " +
                "hasHeader('user-agent', 'Safari')");


        LinkedHashMap<RequestMatcher, AuthenticationEntryPoint> map = 
                new LinkedHashMap<RequestMatcher, AuthenticationEntryPoint>();
        map.put(matcher, new BasicAuthenticationEntryPoint());

        DelegatingAuthenticationEntryPoint delegatingAuthenticationEntryPoint = new DelegatingAuthenticationEntryPoint(map);
        delegatingAuthenticationEntryPoint.setDefaultEntryPoint(new Http403ForbiddenEntryPoint());


        return delegatingAuthenticationEntryPoint;
    }

我总是在客户端获得“HTTP 403”（猜测Http403ForbiddenEntryPoint）。 我也尝试过一个更简单的配置，而没有委托像身份验证这样的。

.httpBasic().authenticationEntryPoint(new BasicAuthenticationEntryPoint())

这也行不通。 有谁知道我做错了什么？

添加：
应该锁定得更好。找到关于这个问题的另一篇文章 need spring security java config example showing basic auth only
票证SEC-2198也已被放置。

当前的解决方法。

.exceptionHandling()
   .authenticationEntryPoint(delegatingAuthenticationEntryPoint())
   .and()
.httpBasic();
