我是新手MuleESB
。我对流量了解不多。我找不到Mule
. 我正在尝试使用以下代码从数据库中获取数据,但我无法获取数据。没有显示错误,所以我不知道该怎么办。我的流程正确吗?
这是我的流程配置。

我正在像这样从 curl 客户端发送请求
curl -H "Content-Type: application/json" -d '{"id":"5"}' http://192.168.25.24:8081/selectdb
它不提供和响应。
我期待像下面这样的回应。
{"Body":{"Datalist":{"firstname":"ff","lastname":"ggg","id":"5"}},"Status":"200"}}
请帮我实现这一点。
甚至记录器语句也没有打印
<logger message="message of payload#[message.payload]" level="INFO" doc:name="Logger"/>
感谢任何帮助。
