问题原因 #

• 空模型文件触发解析失败
  日志中的java.io.EOFException: input contained no data是核心线索：Solr的ModelTracker在加载持久化的Alfresco模型文件时，读取到了一个空的XML文件。Alfresco的字典服务依赖这些模型定义处理元数据，空文件直接导致字典解析失败，抛出DictionaryException，进而让Solr的CoreWatcher任务崩溃。

• Solr异常导致系统核心服务失效
  Alfresco的登录验证、权限管理等核心功能依赖Solr提供的索引和元数据支撑。当Solr的模型跟踪器无法正常工作时，Alfresco无法完成必要的元数据初始化流程，虽然服务器进程能启动，但核心服务处于异常状态，最终导致用户无法登录系统。

• 可能的诱因

  • 异常关机（如强制终止进程、服务器断电）导致Solr的模型持久化文件损坏或为空
  • 文件系统权限不足：Solr进程没有足够权限写入完整的模型文件，导致生成空文件
  • 模型同步过程中出现网络或IO故障，导致模型文件未完整同步到Solr端
