<! DOCTYPE hibernate-mapping Public
"-//hibernate/hibernate Mapping DTD 3.0//en"
"Http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd" >

Then

The <class></class> tag represents the JavaBean feature class for which you want to create a table

<id></id> Configuration Table primary key Id<generator class= "native" ><generator> native:hibernate automatically what kind of database The data is then guaranteed to be unique based on the growth of the primary key from the database type.

<proterty></proterty> to configure a table's fields

<set></set> a one-to-many label to represent that multi-collection

<one-to-one> one-on-one

<one-to-many> one-to-many

<many-to-many> Many-to-many
