我正在遵循发布/订阅的Solace教程(链接:
https://dev.solace.com/samples/solace-samples-java/publish-subscribe/
)因此,代码不应该有任何“错误”。
我正在尝试让topicsubscriber连接到云。在构建jar之后,我运行以下命令:
java -cp target/SOM_Enrichment-1.0-SNAPSHOT.jar TopicSubscriber <host:port> <client-username@message-vpn> <password>
(填写适当的字段)
我得到以下错误:
TopicSubscriber initializing...

下面是topicsubscriber.java文件:
