ActiveMQ Broker Factory 找不到用于故障转移的工厂 class

Question

我在尝试使用 BrokerFactory 创建 ActiveMQ 代理时遇到此错误：

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
    at org.apache.activemq.util.IOExceptionSupport.create(IOExceptionSupport.java:27)

似乎是路径错误或类似的问题，我无法找出根本原因。

这是导致它的代码：

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

这是我正在呼叫的 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？我不包括所需的罐子吗？ url 格式不正确吗？我迷路了。

这不是类路径或 jar 问题。根据活动的 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。
