仅在第二次编译时 Hibernate 搜索程序错误

Question

如果我将运行这个休眠搜索程序第一次正确运行，而如果我第二次编译它会产生错误：

Answer 1

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

此外，如果您运行 Windows 如果您没有正确关闭第一个实例，您也可能会遇到此错误。

请记住，正确关闭任何 Hibernate 应用程序需要您调用 Hibernate SessionFactory 上的 "close()" 方法，或者如果您使用的是 JPA，则必须关闭 EntityManagerFactory.
