可觀測性

Spring Security 開箱即用地與 Spring Observability 整合以進行追蹤；同時，配置度量收集也相當簡單。

追蹤

當存在 ObservationRegistry bean 時，Spring Security 會為以下內容建立追蹤：

  • 過濾器鏈

  • AuthenticationManager，以及

  • AuthorizationManager

Boot 整合

例如，考慮一個簡單的 Boot 應用程式

  • Java

  • Kotlin

@SpringBootApplication
public class MyApplication {
	@Bean
	public UserDetailsService userDetailsService() {
		return new InMemoryUserDetailsManager(
				User.withDefaultPasswordEncoder()
						.username("user")
						.password("password")
						.authorities("app")
						.build()
		);
	}

	@Bean
	ObservationRegistryCustomizer<ObservationRegistry> addTextHandler() {
		return (registry) -> registry.observationConfig().observationHandler(new ObservationTextPublisher());
	}

	public static void main(String[] args) {
		SpringApplication.run(ListenerSamplesApplication.class, args);
	}
}
@SpringBootApplication
class MyApplication {
	@Bean
	fun userDetailsService(): UserDetailsService {
		InMemoryUserDetailsManager(
				User.withDefaultPasswordEncoder()
						.username("user")
						.password("password")
						.authorities("app")
						.build()
		);
	}

	@Bean
	fun addTextHandler(): ObservationRegistryCustomizer<ObservationRegistry> {
		return registry: ObservationRegistry -> registry.observationConfig()
				.observationHandler(ObservationTextPublisher());
	}

	fun main(args: Array<String>) {
		runApplication<MyApplication>(*args)
	}
}

以及相應的請求

?> http -a user:password :8080

將產生以下輸出（為清晰起見添加了縮排）

手動配置

對於非 Spring Boot 應用程式，或者要覆蓋現有的 Boot 配置，您可以釋出自己的 ObservationRegistry，Spring Security 仍會將其拾取。

  • Java

  • Kotlin

  • Xml

@SpringBootApplication
public class MyApplication {
	@Bean
	public UserDetailsService userDetailsService() {
		return new InMemoryUserDetailsManager(
				User.withDefaultPasswordEncoder()
						.username("user")
						.password("password")
						.authorities("app")
						.build()
		);
	}

	@Bean
	ObservationRegistry observationRegistry() {
		ObservationRegistry registry = ObservationRegistry.create();
		registry.observationConfig().observationHandler(new ObservationTextPublisher());
		return registry;
	}

	public static void main(String[] args) {
		SpringApplication.run(ListenerSamplesApplication.class, args);
	}
}
@SpringBootApplication
class MyApplication {
	@Bean
	fun userDetailsService(): UserDetailsService {
		InMemoryUserDetailsManager(
				User.withDefaultPasswordEncoder()
						.username("user")
						.password("password")
						.authorities("app")
						.build()
		);
	}

	@Bean
	fun observationRegistry(): ObservationRegistry {
		ObservationRegistry registry = ObservationRegistry.create()
		registry.observationConfig().observationHandler(ObservationTextPublisher())
		return registry
	}

	fun main(args: Array<String>) {
		runApplication<MyApplication>(*args)
	}
}
<sec:http auto-config="true" observation-registry-ref="ref">
	<sec:intercept-url pattern="/**" access="authenticated"/>
</sec:http>

<!-- define and configure ObservationRegistry bean -->

停用可觀測性

如果您不希望有任何 Spring Security 觀測，在 Spring Boot 應用程式中，您可以釋出一個 ObservationRegistry.NOOP @Bean。然而，這可能會停用不僅僅是 Spring Security 的觀測。

相反，您可以釋出一個如下所示的 SecurityObservationSettings

  • Java

  • Kotlin

@Bean
SecurityObservationSettings noSpringSecurityObservations() {
	return SecurityObservationSettings.noObservations();
}
@Bean
fun noSpringSecurityObservations(): SecurityObservationSettings {
	return SecurityObservationSettings.noObservations()
}

然後 Spring Security 將不會將任何過濾器鏈、認證或授權包裝到其 ObservationXXX 對應項中。

XML 支援沒有停用觀測的功能。相反，只需不設定 observation-registry-ref 屬性。

您還可以僅停用部分 Security 觀測。例如，SecurityObservationSettings bean 預設排除過濾器鏈觀測。因此，您也可以這樣做：

  • Java

  • Kotlin

@Bean
SecurityObservationSettings defaultSpringSecurityObservations() {
	return SecurityObservationSettings.withDefaults().build();
}
@Bean
fun defaultSpringSecurityObservations(): SecurityObservationSettings {
	return SecurityObservationSettings.withDefaults().build()
}

或者您可以根據預設設定單獨開啟和關閉觀測

  • Java

  • Kotlin

@Bean
SecurityObservationSettings allSpringSecurityObservations() {
	return SecurityObservationSettings.withDefaults()
            .shouldObserveFilterChains(true).build();
}
@Bean
fun allSpringSecurityObservations(): SecurityObservationSettings {
    return SecurityObservationSettings.builder()
            .shouldObserveFilterChains(true).build()
}

為了向後相容，除非釋出 SecurityObservationSettings，否則會進行所有 Spring Security 觀測。

追蹤列表

Spring Security 在每個請求上跟蹤以下 span：

  1. spring.security.http.requests - 一個包裝整個過濾器鏈（包括請求）的 span

  2. spring.security.http.chains.before - 一個包裝安全過濾器接收部分的 span

  3. spring.security.http.chains.after - 一個包裝安全過濾器返回部分的 span

  4. spring.security.http.secured.requests - 一個包裝現在已受保護的應用程式請求的 span

  5. spring.security.http.unsecured.requests - 一個包裝 Spring Security 未受保護請求的 span

  6. spring.security.authentications - 一個包裝認證嘗試的 span

  7. spring.security.authorizations - 一個包裝授權嘗試的 span

spring.security.http.chains.before + spring.security.http.secured.requests + spring.security.http.chains.after = spring.security.http.requests
spring.security.http.chains.before + spring.security.http.chains.after = Spring Security 的請求部分
