我已经成功地生成了在Kotlin中实现的Spring Cloud Gateway（2022.0.0 - Sping Boot 3.0.0）应用程序的本机映像。
我有以下安全配置：
@EnableReactiveMethodSecurity
@Configuration(proxyBeanMethods = false)
class SecurityConfiguration(private val clientService: ClientService,
private val env: Environment) {
@Bean
fun springSecurityFilterChain(http: ServerHttpSecurity): SecurityWebFilterChain {
return http.requestCache {
it.requestCache(NoOpServerRequestCache.getInstance())
}.headers { headers ->
headers.frameOptions { frameOptions ->
frameOptions.disable()
}
}.csrf { it.disable() }
.securityContextRepository(NoOpServerSecurityContextRepository.getInstance())
.addFilterAt(basicAuthenticationFilter(), SecurityWebFiltersOrder.HTTP_BASIC)
.authorizeExchange()
.pathMatchers("/actuator/health").permitAll()
...
.and()
.build()
}
@Bean
fun passwordEncoder(): PasswordEncoder {
return createDelegatingPasswordEncoder()
}
private fun basicAuthenticationFilter(): AuthenticationWebFilter {
val authManager = ApiAuthenticationManager(clientService)
val apiAuthenticationFilter = AuthenticationWebFilter(authManager)
return apiAuthenticationFilter
}
}当我运行本机映像时，它崩溃，并出现以下异常：
kotlin.reflect.jvm.internal.KotlinReflectionInternalError: Could not compute caller for function: private open fun basicAuthenticationFilter(): org.springframework.security.web.server.authentication.AuthenticationWebFilter defined in xxx.configuration.SecurityConfiguration[DeserializedSimpleFunctionDescriptor@3ff718f] (member = null)

有什么办法解决这个问题吗？

Spring Security使用反射来获取自定义过滤器的类，以便跟踪过滤器链中的顺序。
要将代码作为本机映像运行，需要一个反射提示来告诉GraalVM私有方法
basicAuthenticationFilter需要在本机映像中可用。可以使用
RuntimeHintsRegistrar添加自定义提示。在这种情况下，可以使用以下命令注册basicAuthenticationFilter以进行反射：
