Question

如果我第一次运行这个hibernate搜索程序它正常工作，而如果我第二次编译它会产生错误：

   ERROR: HSEARCH000058: Exception occurred org.apache.lucene.store.LockObtainFailedException: Lock obtain timed out: NativeFSLock@D:\data\index\com.srccodes.example.hibernate.Contact\write.lock

Answer 1

如果您的Hibernate Search应用程序的第一个实例仍在运行（在任何操作系统上），您将收到此类错误。

此外，如果您正在运行Windows，如果没有正确关闭第一个实例，也可能会出现此错误。

请记住，正确关闭任何Hibernate应用程序需要您在Hibernate SessionFactory上调用“close（）”方法，或者如果您使用JPA，则必须关闭{{1 }}

Hibernate搜索程序错误仅在第二次编译时出错
