可观察性

Spring Security 与 Spring Observability 集成在一起，开箱即用，用于跟踪;尽管配置收集指标也非常简单。spring-doc.cadn.net.cn

描图

当ObservationRegistrybean 存在，则 Spring Security 会为以下对象创建跟踪：spring-doc.cadn.net.cn

引导集成

例如，考虑一个简单的 Boot 应用程序：spring-doc.cadn.net.cn

@SpringBootApplication
public class MyApplication {
	@Bean
	public ReactiveUserDetailsService userDetailsService() {
		return new MapReactiveUserDetailsManager(
				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(): ReactiveUserDetailsService {
		MapReactiveUserDetailsManager(
				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)
	}
}

以及相应的请求：spring-doc.cadn.net.cn

?> http -a user:password :8080

将产生以下输出（为清楚起见，添加了缩进）：spring-doc.cadn.net.cn

手动配置

对于非 Spring Boot 应用程序，或者要覆盖现有的 Boot 配置，你可以发布自己的ObservationRegistrySpring Security 仍将获取它。spring-doc.cadn.net.cn

@SpringBootApplication
public class MyApplication {
	@Bean
	public ReactiveUserDetailsService userDetailsService() {
		return new MapReactiveUserDetailsManager(
				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(): ReactiveUserDetailsService {
		MapReactiveUserDetailsManager(
				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 -->

禁用可观测性

如果您不需要任何 Spring Security 观察，您可以在 Spring Boot 应用程序中发布一个ObservationRegistry.NOOP @Bean. 但是，这可能会关闭 Spring Security 以外的其他 Observations。spring-doc.cadn.net.cn

相反，您可以发布SecurityObservationSettings如下所示：spring-doc.cadn.net.cn

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

然后 Spring Security 不会在其ObservationXXX同行。spring-doc.cadn.net.cn

没有用于禁用具有 XML 支持的观测值的工具。 相反，只需不设置observation-registry-ref属性。

您还可以仅对 Security 的观察子集禁用安全性。 例如，SecurityObservationSettings默认情况下，Bean 排除 Filter Chain 观察值。 因此，您还可以执行以下作：spring-doc.cadn.net.cn

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

或者，您可以根据默认值单独打开和关闭观察：spring-doc.cadn.net.cn

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

为了向后兼容，除非SecurityObservationSettings发布。spring-doc.cadn.net.cn

跟踪列表

Spring Security 在每个请求上跟踪以下 span：spring-doc.cadn.net.cn

  1. spring.security.http.requests- 包装整个过滤器链（包括请求）的 spanspring-doc.cadn.net.cn

  2. spring.security.http.chains.before- 包装安全过滤器的接收部分的 spanspring-doc.cadn.net.cn

  3. spring.security.http.chains.after- 包装安全过滤器的返回部分的 spanspring-doc.cadn.net.cn

  4. spring.security.http.secured.requests- 包装现在保护的应用程序请求的 SPANspring-doc.cadn.net.cn

  5. spring.security.http.unsecured.requests- 包装 Spring Security 不保护的请求的 spanspring-doc.cadn.net.cn

  6. spring.security.authentications- 包装身份验证尝试的 SPANspring-doc.cadn.net.cn

  7. spring.security.authorizations- 包装授权尝试的 SPANspring-doc.cadn.net.cn

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 的请求部分
