Error notes in Hibernate

1. In writing Student.hbm.xml, when the table field in the Hibernate-mapping class and database is specified, the property is accidentally written as properties, error:

ERROR:HHH000196:Error parsing XML (2): The content of element type "class" must match "(Meta*,subselect?,cache?,synchro nize*,comment?,tuplizer*, (Id|composite-id), Discriminator?,natural-id?, (Version|timestamp)?, (property| Many-to-one|one-to-one|component|dynamic-component|properties|any|map|set|list|bag|idbag|array|primitive-array ) *, ((join*,subclass*) |joined-subclass*|union-subclass*), loader?,sql-insert?,sql-update?,sql-delete?,filter*, fetch-profile*,resultset*, (query|sql-query) *) ".

The reason: property is written in the properties

Property and properties are the same meaning, what is the difference between them?

The properties are used for importing external resources, followed by a path to the properties file,

2. In the Hibernate.cfg.xml file, specify the class

<mapping resource= "Com/bjsxt/hibernate/student.hbm.xml"/>

Is '/' not '. '

<mapping resource= "Com.bjsxt.hibernate/student.hbm.xml"/>
