我如何从连接jsonarray中获取键connectionid的值？

Question

服务器的输出...。

{
 "code": 201,
 "message": "Connection ROH_DB|rsh266939369 created",
 "connections": {"connectionid": "ROH_DB|rsh266939369"},
 "status": "Created"
}

System.out.println("Output from Server .... \n");
String output = response.getEntity(String.class);
System.out.println(output);
