openfire插件入门学习

 

我在网络上找了很多openfire插件的制作的案例  但是都是不全 以下实例来源于

非常感谢这位前辈的分享，解决了偶的燃眉之急

 

openfire 版本3.6.4

关于插件开发的基本信息，可以参考其自带的文档页plugin-dev-guide.html

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<iq id="xxx" type="set"><b xmlns="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. package test.plugin; 
9. import org.dom4j.Element; 
10. import org.jivesoftware.openfire.IQHandlerInfo; 
11. import org.jivesoftware.openfire.XMPPServer; 
12. import org.jivesoftware.openfire.auth.UnauthorizedException; 
13. import org.jivesoftware.openfire.handler.IQHandler; 
14. import org.xmpp.packet.IQ; 
16. public class BroadcastsIQ extends IQHandler { 
18. private IQHandlerInfo info; 
19. public BroadcastsIQ() { 
20. super("用户广播模块"); 
21.         info = new IQHandlerInfo("b", "com:message:broadcasts"); 
22.     } 
24. @Override
25. public IQHandlerInfo getInfo() { 
26. return info; 
27.     } 
29. @Override
30. public IQ handleIQ(IQ packet) throws UnauthorizedException { 
31.         Element iq = packet.getElement(); 
32.         Element b = iq.element("b"); 
33.         String text = b.getText(); 
34.         XMPPServer.getInstance().getSessionManager().sendServerMessage(null, text);//广播信息
35. return null; 
36.     } 
38. } 
40. 建立org.jivesoftware.openfire.container.Plugin的实现类 
41. package test.plugin; 
43. import java.io.File; 
44. import java.util.List; 
46. import org.jivesoftware.openfire.XMPPServer; 
47. import org.jivesoftware.openfire.container.Plugin; 
48. import org.jivesoftware.openfire.container.PluginManager; 
49. import org.jivesoftware.openfire.handler.IQHandler; 
51. public class MyPlugin implements Plugin { 
53. private IQHandler iQHandler; 
54. @Override
55. public void destroyPlugin() { 
56.         XMPPServer.getInstance().getIQRouter().removeHandler(iQHandler); 
57.         System.out.println("插件停止成功"); 
58.     } 
60. @Override
61. public void initializePlugin(PluginManager manager, File pluginDirectory) { 
62.         iQHandler = new BroadcastsIQ(); 
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. <?xml version="1.0" encoding="UTF-8"?> 
70. <plugin> 
71.     <class>test.plugin.MyPlugin</class> 
72.     <name>Broadcasts messages</name> 
73.     <description>This is an Broadcasts messages plugin.</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. package test.xmpp; 
106. import org.jivesoftware.smack.packet.IQ; 
108. public class Broadcasts extends IQ { 
110. private String body; 
111. public String getElementName() { 
112. return "b"; 
113.     } 
115. public String getNamespace() { 
116. return "com:message:broadcasts"; 
117.     } 
119. public void setBody(String body) { 
120. this.body = body; 
121.     } 
123. public String getBody() { 
124. return body; 
125.     } 
127. @Override
128. public String getChildElementXML() { 
129. if(getBody() == null){ 
130. throw new RuntimeException("Broadcasts body is empty"); 
131.         } 
132.         StringBuilder sb = new StringBuilder(); 
133.         sb.append("<").append(getElementName()).append(" xmlns=\"").append(getNamespace()).append("\">").append(getBody()).append("</").append(getElementName()).append(">"); 
134. return sb.toString(); 
135.     } 
137. } 
139. 然后在程序中 
141. Broadcasts b = new Broadcasts(); 
142. b.setBody("测试广播内容"); 
143. b.setType(IQ.Type.SET); 
144. conn.sendPacket(b);
