Spring(引导)安全预身份验证，允许的资源仍然经过身份验证

我使用的是 Spring Boot 1.5.6(也尝试过 1.5.4).我正在使用

I am using Spring Boot 1.5.6 (also have tried with 1.5.4). I am using a

RequestHeaderAuthenticationFilter 

和一个

PreAuthenticatedAuthenticationProvider 

保护我的 spring mvc web 应用程序，并允许访问控制器路径和静态资源.

to secure my spring mvc web app and also permit access to both a controller path and static resources.

在我的

RequestHeaderAuthenticationFilter

设置我想要

setExceptionIfHeaderMissing(true);

以便我知道请求中是否发送了标头变量.

so that I know if the header variable has been sent in the request.

当我尝试访问任何允许的资源时，Spring Security 总是在请求中查找标头变量并抛出一个

When I try to access any of the permitted resources, Spring Security always looks for the header variable in the request and throws a

PreAuthenticatedCredentialsNotFoundException

为什么即使我试图访问允许的(不受保护的)资源，spring security 仍然试图查找预先验证的主体?我该如何规避这种行为?

Why is spring security still trying to look up the preauthenticated principal even though I am trying to access a permitted (non-protected) resource? How can I circumvent this behaviour?

我的 WebSecurityConfigurerAdapter 的 java 配置如下

My java config for WebSecurityConfigurerAdapter is below

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter{


private static final Logger log = LoggerFactory.getLogger(SecurityConfig.class);


@Autowired
protected UserDetailsService userDetailsService; 



@Bean
public PreAuthenticatedAuthenticationProvider preAuthenticatedAuthenticationProvider(){

    log.info("Configuring pre authentication provider");

    UserDetailsByNameServiceWrapper<PreAuthenticatedAuthenticationToken> wrapper = 
            new UserDetailsByNameServiceWrapper<PreAuthenticatedAuthenticationToken>(
                    userDetailsService);

    PreAuthenticatedAuthenticationProvider it = new PreAuthenticatedAuthenticationProvider();
    it.setPreAuthenticatedUserDetailsService(wrapper);

    return it;      
} 

@Bean
public RequestHeaderAuthenticationFilter requestHeaderAuthenticationFilter() throws Exception{

    RequestHeaderAuthenticationFilter it = new RequestHeaderAuthenticationFilter();
    it.setAuthenticationManager(authenticationManager());
    it.setExceptionIfHeaderMissing(true);
    return it;
}

@Override
public void configure(AuthenticationManagerBuilder auth) throws Exception {
    log.info("configure authentication provider");
    auth.authenticationProvider(preAuthenticatedAuthenticationProvider());

}


@Override
protected void configure(HttpSecurity http) throws Exception {
    log.info("Configure HttpSecurity");
    http
        .authorizeRequests()
            .antMatchers("/permitted/**", "/css/**", "/js/**", "/images/**", "/webjars/**")
                .permitAll()
            .anyRequest()
                    .authenticated()
            .and().addFilter(requestHeaderAuthenticationFilter())

    ;
}    


 @Override
 public void configure(WebSecurity web) throws Exception {
     web
        .ignoring()
            .antMatchers("/permitted/**", "/css/**", "/js/**", "/images/**", "/webjars/**"); 
}   
}
