Resilience4j v0.13.2 发布，面向 Java 8 和函数式编程的容错库

Resilience4j v0.13.2 发布了，Resilience4j 是一个轻量级的容错组件，其灵感来自于Hystrix，但主要为 Java 8 和函数式编程所设计。轻量级体现在其只用 Vavr库（前身是 Javaslang），没有任何外部依赖。而 Hystrix 依赖了 Archaius ，Archaius 本身又依赖很多第三方包，例如 Guava、Apache Commons Configuration 等。

Resilience4j 提供了如下几款核心组件

• resilience4j-circuitbreaker: Circuit breaking

• resilience4j-ratelimiter: Rate limiting

• resilience4j-bulkhead: Bulkheading

• resilience4j-retry: Automatic retrying (sync and async)

• resilience4j-cache: Response caching

限速组件架构：

更新内容包括 bug 修复、新增特性以及移除旧功能，具体如下：

• PR #244 : Corrected link to Prometheus Metrics Integration

• PR #246 : Make async retrofit call not make the request when circuit is open

• PR #248 : Removed rxjava2 dependency for time limiter

• PR #253 : Fixed documentation

• PR #254 : Additional factory methods for Micrometer CircuitBreakerMetrics

• PR #271 : Remove deprecated usage of Mockito Matchers

• PR #276 : Add response predicate to retry sync and async for enhancement

• PR #277 : Generate BOM for resilience4j

• PR #281 : Avoid creating unnecessary logging strings

• PR #284 : Avoiding calling bulkheadConfigSupplier needlessly

• Issue #245 ; PR  #260 : Fix CircuitBreakerSubscriber for Reactor doesn’t count successes when using Mono/Flux.toFuture()

• Issue #263 ; PR  #264 : Fix bulkhead on Single and Maybe
