如何從慰藉中獲得所有隊列和主題

Question

我想從安慰中發現所有目的地（隊列和主題）

我嘗試使用MBeanServerConnection並在名稱后進行查詢（但我沒有找到使用此名稱的正確方法）或JNDI查找Destination dest =（Destination）context.lookup（Dest_name），但我沒有隊列的名稱/主題。 我正在使用solace-jms庫。

我正在搜索這樣的東西：（但要安慰，而不是activeMq） 從activeMQ獲取所有隊列

Answer 1

為此，您將需要通過管理界面使用SEMP。

示例命令：

curl -d '<rpc><show><queue><name>*</name></queue></show></rpc>' -u semp_username:semp_password http://your_management_ip:your_management_port/SEMP
curl -d '<rpc><show><topic-endpoint><name>*</name></topic-endpoint></show></rpc>' -u semp_username:semp_password http://your_management_ip:your_management_port/SEMP

請注意，為了簡化起見，我使用curl ，但是任何應用程序都可以執行HTTP POST來執行這些命令。 如果使用的是Java，則可以參考Solace API示例中的SempHttpSetRequest示例。

關於SEMP的文檔可以在這里找到。

但是，這里更大的問題是為什么您需要發現所有目的地？

消息代理的功能之一是使發布者和使用者脫鈎。

如果您需要了解是否將持久消息發布到沒有使用者的主題中，則可以使用發布應用程序的客戶端配置文件中的“拒絕訂閱的味精到發件人”設置。 這意味着，如果發布者嘗試發布有關主題不匹配的訂閱者的消息，則發布者將獲得否定確認。

您可以參考https://docs.solace.com/Configuring-and-Managing/Configuring-Client-Profiles.htm上的“處理不匹配的保證消息”以獲取更多詳細信息。

這是一些可能有用的源代碼。 正確配置設備后，還可以通過JMS在主題“＃SEMP /（路由器）/ SHOW”上使用SEMP。

Answer 3

您可以使用以下SEMPv2命令獲取特定於消息VPN的隊列和主題。

curl -s -X GET -u semp_user:semp_pass management_host:management_port/SEMP/v2/monitor/msgVpns/{vpn-name}/queues?select="queueName"

curl -s -X GET -u semp_user:semp_pass management_host:management_port/SEMP/v2/monitor/msgVpns/{vpn-name}/topicEndpoints?select="topicEndpointName"
