可观测性

DeepSeek V3 中英对照 Observability

Spring Security 与 Spring Observability 开箱即用，支持追踪功能；同时配置以收集指标也相当简单。

追踪

当存在 ObservationRegistry bean 时，Spring Security 会为以下操作创建追踪：

过滤器链
AuthenticationManager（认证管理器），以及
AuthorizationManager（授权管理器）

启动集成

例如，考虑一个简单的Boot应用程序：

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)
	}
}

以及相应的请求：

?> http -a user:password :8080

将产生以下输出（为清晰起见，已添加缩进）：

手动配置

对于非Spring Boot应用程序，或者需要覆盖现有的Boot配置，您可以发布自己的ObservationRegistry，Spring Security仍会识别并使用它。

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 -->

禁用可观测性

如果你不希望启用任何 Spring Security 观测功能，在 Spring Boot 应用中，你可以发布一个 ObservationRegistry.NOOP 类型的 @Bean。然而，这可能会关闭不仅仅是 Spring Security 的观测功能。

相反，你可以发布一个如下所示的 SecurityObservationSettings：

Java
Kotlin

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

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

然后Spring Security将不会将任何过滤器链、认证或授权包装到它们的ObservationXXX对应版本中。

提示

目前没有通过 XML 配置来禁用观测功能的机制。只需不设置 observation-registry-ref 属性即可。

你也可以仅针对Security的部分观测项禁用安全功能。例如，默认情况下，SecurityObservationSettings bean会排除过滤器链的观测。因此，你也可以这样做：

Java
Kotlin

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

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

或者，您可以根据默认设置单独开启或关闭观测功能：

Java
Kotlin

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

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

备注

为了向后兼容，除非发布了一个 SecurityObservationSettings，否则所有 Spring Security 的观测都会被启用。

跟踪列表

Spring Security 会在每个请求中追踪以下跨度：

spring.security.http.requests - 一个包装整个过滤器链（包括请求）的跨度
spring.security.http.chains.before - 一个包装安全过滤器接收部分的跨度
spring.security.http.chains.after - 一个包装安全过滤器返回部分的跨度
spring.security.http.secured.requests - 一个包装现已受保护的应用请求的跨度
spring.security.http.unsecured.requests - 一个包装 Spring Security 未保护请求的跨度
spring.security.authentications - 一个包装身份验证尝试的跨度
spring.security.authorizations - 一个包装授权尝试的跨度

提示

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 在请求处理中的部分
