【问题分析】

IQRosterHandler——

* Implements the TYPE_IQ jabber:iq:roster protocol. Clients
* use this protocol to retrieve, update, and rosterMonitor roster
* entries (buddy lists). The server manages the basics of
* roster subscriptions and roster updates based on presence
* and iq:roster packets, while the client maintains the user
* interface aspects of rosters such as organizing roster
* entries into groups.

private IQ manageRoster(org.xmpp.packet.Roster packet) throws UnauthorizedException,
UserAlreadyExistsException, SharedGroupException {

......

if ((sender.getNode() == null || !RosterManager.isRosterServiceEnabled() || <--此处isRosterServiceEnabled返回false，导致后面空roster回复
!userManager.isRegisteredUser(sender.getNode())) &&
IQ.Type.get == type) {
// If anonymous user asks for his roster or roster service is disabled then
// return an empty roster
IQ reply = IQ.createResultIQ(packet);
reply.setChildElement("query", "jabber:iq:roster");
return reply;

继续：

public static boolean isRosterServiceEnabled() {
boolean bRet = JiveGlobals.getBooleanProperty("xmpp.client.roster.active", true); <--原来“系统属性”-->"xmpp.client.roster.active"被置为false了

return bRet;
}

【解决方案】

“系统属性”-->"xmpp.client.roster.active"置为true，收发报文正确

C2S - RECV (2944378): <iq id="j9O8X-2" type="get"><query xmlns="jabber:iq:roster"></query></iq>
INTERPRETED: <iq id="j9O8X-2" type="get" from="zjx@10.10.122.171/Spark 2.6.3"><query xmlns="jabber:iq:roster"/></iq>
C2S - SENT (2944378): <iq type="result" id="j9O8X-2" to="zjx@10.10.122.171/Spark 2.6.3"><query xmlns="jabber:iq:roster"><item jid="wfp@10.10.122.171" name="wfp" subscription="both"><group>Friends</group></item></query></iq>

但是spark客户端在A电脑登录还是无法显示其roster，同一账号在B电脑上登录就显示正常；

尝试将C:\Users\lenovo\AppData\Roaming\Spark下的内容删除，同时重装spark，问题依然；

后面尝试在A中Spark面板 -->联系人 -->显示离线用户选项勾选，即能够正常看到roster；但是B中没有勾选却能正常显示。估计此为spark的bug
