太棒了！你已经非常接近成功了，而且这次我们有关键进展： --- ## ✅ 重要确认：你这次的 `RestApiPlugin.java` 写入是正确的！ 运行命令： ```bash cat src/RestApiPlugin.java ``` 输出如下（已格式化）： ```java public class RestApiPlugin implements org.jivesoftware.openfire.container.Plugin { static { System.out.println("[PLUGIN-DEBUG] 💡 静态块执行：RestApiPlugin 类已被 JVM 加载！"); System.out.println("[PLUGIN-DEBUG] 📦 类资源位置: " + RestApiPlugin.class.getResource("RestApiPlugin.class")); } public RestApiPlugin() { System.out.println("[PLUGIN-DEBUG] 🆕 构造函数执行：RestApiPlugin 实例已创建"); } @Override public void initializePlugin(org.jivesoftware.openfire.container.PluginManager manager, java.io.File pluginDirectory) { System.out.println("[PLUGIN-DEBUG] 🎉 插件初始化成功！插件目录: " + pluginDirectory.getAbsolutePath()); } @Override public void destroyPlugin() { System.out.println("[PLUGIN-DEBUG] 🔌 插件已销毁"); } } ``` ✅ **完全正确**！没有断行、没有拼接错误。这意味着编译出来的 `.class` 文件中确实包含调试日志。 --- ## ❌ 但是：Openfire 仍然没有加载它 你在日志中看到的是： ``` 2025.10.03 04:49:05.867 INFO [PluginMonitorTask-2]: org.jivesoftware.openfire.container.PluginMonitor - Plugin 'restapi' was removed from the file system. 2025.10.03 04:49:05.868 ERROR [PluginMonitorTask-2]: ... java.lang.NullPointerException: null at PluginManager.unloadPlugin(PluginManager.java:883) ``` 这说明 Openfire 扫描到了 `/opt/openfire/plugins/restapi` 目录，但尝试加载失败 → 标记为“已删除” → 触发 NPE。 但我们最关心的是：**为什么看不到任何 `[PLUGIN-DEBUG]` 日志？** --- ## 🔍 原因分析：很可能是因为 `System.out.println` 输出被重定向或未显示在 `openfire.log` Openfire 使用 Log4j 管理日志，而 `System.out` 默认可能不写入 `openfire.log`，尤其是在生产配置下。 👉 即使类被加载、静态块执行了，你也**看不到 `System.out.println` 的输出**！ --- ## ✅ 解决方案：改用 Openfire 的日志系统 —— `Log.debug()` 或 `Log.info()` 我们需要使用 Openfire 自带的日志工具类：`org.slf4j.Logger` 和 `org.slf4j.LoggerFactory` ### 修改后的 `RestApiPlugin.java`（使用 SLF4J 日志） ```bash cd ~/openfire-plugin-build rm -f src/RestApiPlugin.java ``` 然后写入： ```bash echo -e 'import org.slf4j.Logger;\n' \ 'import org.slf4j.LoggerFactory;\n' \ '\n' \ 'public class RestApiPlugin implements org.jivesoftware.openfire.container.Plugin {\n' \ '\n' \ ' private static final Logger Log = LoggerFactory.getLogger(RestApiPlugin.class);\n' \ '\n' \ ' static {\n' \ ' Log.info("[PLUGIN-DEBUG] 💡 静态块执行：RestApiPlugin 类已被 JVM 加载！");\n' \ ' Log.info("[PLUGIN-DEBUG] 📦 类资源位置: {}", RestApiPlugin.class.getResource("RestApiPlugin.class"));\n' \ ' }\n' \ '\n' \ ' public RestApiPlugin() {\n' \ ' Log.info("[PLUGIN-DEBUG] 🆕 构造函数执行：RestApiPlugin 实例已创建");\n' \ ' }\n' \ '\n' \ ' @Override\n' \ ' public void initializePlugin(org.jivesoftware.openfire.container.PluginManager manager, java.io.File pluginDirectory) {\n' \ ' Log.info("[PLUGIN-DEBUG] 🎉 插件初始化成功！插件目录: {}", pluginDirectory.getAbsolutePath());\n' \ ' }\n' \ '\n' \ ' @Override\n' \ ' public void destroyPlugin() {\n' \ ' Log.info("[PLUGIN-DEBUG] 🔌 插件已销毁");\n' \ ' }\n' \ '}' > src/RestApiPlugin.java ``` --- ### ✅ 重新编译 & 部署 ```bash # 编译（保持原有 classpath） /usr/lib/jvm/java-11-openjdk/bin/javac \ -source 11 -target 11 \ -cp "/opt/openfire/lib/xmppserver-4.9.2.jar" \ -d classes \ src/RestApiPlugin.java # 打包 jar cf restapi.jar -C classes . # 删除旧插件和缓存 rm -rf /opt/openfire/plugins/restapi rm -rf /opt/openfire/work/plugins/restapi* # 部署 mkdir -p /opt/openfire/plugins/restapi cp restapi.jar /opt/openfire/plugins/restapi/ # 确保 plugin.xml 正确 cat > /opt/openfire/plugins/restapi/plugin.xml << 'EOF' <?xml version="1.0" encoding="UTF-8"?> <plugin> <className>RestApiPlugin</className> <name>REST API Plugin</name> <description>Simple REST API Plugin with SLF4J Logs</description> <author>Admin</author> <version>1.0.0</version> <date>2025-10-03</date> <minServerVersion>4.0.0</minServerVersion> </plugin> EOF # 权限 chown -R openfire:openfire /opt/openfire/plugins/restapi chmod -R 755 /opt/openfire/plugins/restapi # 重启 systemctl restart openfire # 查看日志 tail -f /opt/openfire/logs/openfire.log ``` --- ## ✅ 成功标志（你会看到这些日志） ``` [PLUGIN-DEBUG] 💡 静态块执行：RestApiPlugin 类已被 JVM 加载！ [PLUGIN-DEBUG] 📦 类资源位置: jar:file:/opt/openfire/plugins/restapi/restapi.jar!/RestApiPlugin.class [PLUGIN-DEBUG] 🆕 构造函数执行：RestApiPlugin 实例已创建 [PLUGIN-DEBUG] 🎉 插件初始化成功！插件目录: /opt/openfire/plugins/restapi INFO [PluginManager] Successfully loaded plugin: restapi ``` 这一次，由于使用了 `Log.info()`，日志一定会出现在 `openfire.log` 中！ --- ## 🛠️ 补充验证：检查 JAR 是否真的包含了新代码 ```bash unzip -p restapi.jar RestApiPlugin.class | strings | grep PLUGIN-DEBUG ``` 你应该能看到所有四条日志字符串。 --- ## 🧩 总结 | 问题 | 原因 | 解决 | |------|------|-------| | ❌ 没有看到调试日志 | 使用了 `System.out.println`，但输出未进入 `openfire.log` | 改用 `Log.info()`（SLF4J） | | ⚠️ `NullPointerException` in `unloadPlugin` | Openfire 尝试卸载一个加载失败的插件 | 是现象不是根本原因 | | 🔁 插件被反复标记“已删除” | 加载失败导致扫描器认为插件消失 | 修复后自动消失 | ---
