Kotlin spring安全配置

1.0.0-beta-3595从1.0.0-beta-242以下代码升级到Kotlin后不编译:

@Throws(Exception::class)
override fun configure(http: HttpSecurity)
{
    http.addFilterBefore(AuthenticationFilter(authenticationManager()), BasicAuthenticationFilter::class.java)

    http.csrf().disable()
            .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS)
            .and().authorizeRequests()
            .antMatchers("/authorization/**", "/public/**").permitAll()
            .antMatchers("/**").authenticated()
}

返回的错误是:

SecurityAssembly.kt: (48, 65): Unresolved reference: permitAll

编辑:

permitAll方法的签名来自流行的Spring Security框架:

public ExpressionInterceptUrlRegistry permitAll() {
    return access(permitAll);
}

我错过了什么或这是一个错误吗？
