我在WSO2 ESB 4.5.0中有一个代理服务,它应该处理来自webclient的SOAP请求,将信息发送到JMS主题,然后响应webclient。
问题在于,当我使用JMS-sender时,它默认等待临时队列的响应。
要更改JMS-Sender的行为,我可以将OUT_ONLY设置为true,但是webclient根本没有得到响应。
即使我将OUT_ONLY设置为true,有没有办法返回响应?
OR
我可以将JMS-Sender设置为在不将OUT_ONLY发送到true的情况下不期待回复吗?

根据您的要求,您可能需要使用Messagestore,请参考以下配置,该消息将消息存储在JMSStore中并将确认发送回客户端(成功或失败),然后ESB使用forward schedul处理器,保证JMSStore中的商店消息将被传递到后端,并且在真实BE(可能是JMS)失败的情况下,它会退出,因此util会传递消息,因此它不会从Message存储中删除,这是一个部分如何使用WSO2 ESB完成DEAD LATTER CHANNELING
