java - ActiveMQ Broker Factory 找不到用于故障转移的工厂类

Question

尝试使用 BrokerFactory 创建 ActiveMQ 代理时出现此错误:

java.io.IOException: Could not load failover factory:java.io.IOException: Could not find factory class for resource: META-INF/services/org/apache/activemq/broker/failover

似乎是路径错误或类似的问题，我只是无法找出根本原因。

这是导致它的代码:

URI brokerUri = new URI(bean.getBrokerConfigUrl());
broker = BrokerFactory.createBroker(brokerUri);

这是我调用的 url:

failover:(tcp://internalUrl.net:port#,tcp://internalUrl.net:port#)?randomize=false&timeout=30000&jms.redeliveryPolicy.maximumRedeliveries=-1&jms.prefetchPolicy.all=0

这可能是路径错误吗？我不包括所需的 jar 吗？ url 格式不正确？我在这里迷路了。

这不是类路径或 jar 问题。根据 Activity 的 MQ 文档，BrokerFactory 仅支持 xbean、代理或属性的 URI，不支持故障转移 URI。

以下两个文档应该为您提供有关设置和配置代理工厂的更多信息。
