【问题描述】：

我有一个网络应用程序。该应用程序基于 JSF。我的应用程序不是基于 maven。它使用 ant 进行构建。最近我在我的应用程序中实现了 Hystrix 断路器。它工作正常。我收到“java.lang.NoSuchMethodError：rx.subjects.BehaviorSubject.hasValue()Z”。 相同的配置正在开发中。 Hystrix的详细信息如下。

我使用的库是

archaius-core-0.4.1.jar
HdrHistogram-2.1.9.jar
hystrix-core-1.5.6.jar
newrelic-api-2.21.4.jar
rxjava-1.2.0.jar
rxjava-core-0.20.3.jar

############################################################################################################

# Command/Group specific overrides
hystrix.command.lookup.execution.isolation.thread.timeoutInMilliseconds=30000

【问题讨论】：

rxjava-core-0.20.3.jar?尝试不使用它。

成功了，谢谢@akarnokd

【参考方案1】：

只需要从依赖中删除“rxjava-core-0.20.3.jar”即可
