Java代码

1. 实现功能，客户端发送一个IQ包含内容的节给服务器，服务器取得内容，然后广播给所有的在线用户
3. 新定义的iq为<iqid="xxx"type="set"><bxmlns="com:message:broadcasts">输入发言内容</b></iq>
5. 服务器端：
6. 建立org.jivesoftware.openfire.handler.IQHandler的实现类
7. packagetest.plugin;
9. importorg.dom4j.Element;
10. importorg.jivesoftware.openfire.IQHandlerInfo;
11. importorg.jivesoftware.openfire.XMPPServer;
12. importorg.jivesoftware.openfire.auth.UnauthorizedException;
13. importorg.jivesoftware.openfire.handler.IQHandler;
14. importorg.xmpp.packet.IQ;
16. publicclassBroadcastsIQextendsIQHandler{
18. privateIQHandlerInfoinfo;
19. publicBroadcastsIQ(){
20. super("用户广播模块");
21. info=newIQHandlerInfo("b","com:message:broadcasts");
22. }
24. @Override
25. publicIQHandlerInfogetInfo(){
26. returninfo;
27. }
29. @Override
30. publicIQhandleIQ(IQpacket)throwsUnauthorizedException{
31. Elementiq=packet.getElement();
32. Elementb=iq.element("b");
33. Stringtext=b.getText();
34. XMPPServer.getInstance().getSessionManager().sendServerMessage(null,text);//广播信息
35. returnnull;
36. }
38. }
40. 建立org.jivesoftware.openfire.container.Plugin的实现类
41. packagetest.plugin;
43. importjava.io.File;
44. importjava.util.List;
46. importorg.jivesoftware.openfire.XMPPServer;
47. importorg.jivesoftware.openfire.container.Plugin;
48. importorg.jivesoftware.openfire.container.PluginManager;
49. importorg.jivesoftware.openfire.handler.IQHandler;
51. publicclassMyPluginimplementsPlugin{
53. privateIQHandleriQHandler;
54. @Override
55. publicvoiddestroyPlugin(){
56. XMPPServer.getInstance().getIQRouter().removeHandler(iQHandler);
57. System.out.println("插件停止成功");
58. }
60. @Override
61. publicvoidinitializePlugin(PluginManagermanager,FilepluginDirectory){
62. iQHandler=newBroadcastsIQ();
63. XMPPServer.getInstance().getIQRouter().addHandler(iQHandler);
64. System.out.println("插件运行成功");
65. }
66. }
68. 建立plugin.xml文件
69. <?xmlversion="1.0"encoding="UTF-8"?>
70. <plugin>
71. <class>test.plugin.MyPlugin</class>
72. <name>Broadcastsmessages</name>
73. <description>ThisisanBroadcastsmessagesplugin.</description>
74. <author>me</author>
76. <version>1.0</version>
77. <date>01/01/2011/date>
78. <url>none</url>
79. <minServerVersion>3.0.0</minServerVersion>
80. <licenseType>gpl</licenseType>
81. <adminconsole>
82. </adminconsole>
83. </plugin>
85. 打包为任意名称的jar文件
86. 结构如下
87. test.jar
88. --classes
89. --test
90. --plugin
91. --BroadcastsIQ.class
92. --MyPlugin.class
93. --META-INF
94. --MANIFEST.MF
95. --plugin.xml
99. 然后把打好包的jar文件放到openfire的plugins目录下，openfire会自动加载，观察控制台是否输出插件运行成功
102. 客户端：
103. 建立org.jivesoftware.smack.packet.IQ的实现类
104. packagetest.xmpp;
106. importorg.jivesoftware.smack.packet.IQ;
108. publicclassBroadcastsextendsIQ{
110. privateStringbody;
111. publicStringgetElementName(){
112. return"b";
113. }
115. publicStringgetNamespace(){
116. return"com:message:broadcasts";
117. }
119. publicvoidsetBody(Stringbody){
120. this.body=body;
121. }
123. publicStringgetBody(){
124. returnbody;
125. }
127. @Override
128. publicStringgetChildElementXML(){
129. if(getBody()==null){
130. thrownewRuntimeException("Broadcastsbodyisempty");
131. }
132. StringBuildersb=newStringBuilder();
133. sb.append("<").append(getElementName()).append("xmlns=\"").append(getNamespace()).append("\">").append(getBody()).append("</").append(getElementName()).append(">");
134. returnsb.toString();
135. }
137. }
139. 然后在程序中
141. Broadcastsb=newBroadcasts();
142. b.setBody("测试广播内容");
143. b.setType(IQ.Type.SET);
144. conn.sendPacket(b);
