Explain hibernate mapping file

1.	Explain hibernate mapping file
Answer» Hibernate mapping file is an XML file that is used for defining the entity bean fields and corresponding database column mappings. These files are useful when the project uses third-party classes where JPA annotations provided by hibernating cannot be used. In the previous example, we have defined the mapping resource as “InterviewBitEmployee.hbm.xml” in the config file. Let us SEE what that sample hbm.xml file looks like: <?xml version = "1.0" encoding = "utf-8"?><!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD//EN""HTTP://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd"><hibernate-mapping> <!-- What class is mapped to what database table--> <class name = "InterviewBitEmployee" table = "InterviewBitEmployee"> <meta attribute = "class-description"> This class CONTAINS the details of employees of InterviewBit. </meta> <ID name = "id" type = "INT" column = "employee_id"> <generator class="native"/> </id> <property name = "fullName" column = "full_name" type = "string"/> <property name = "email" column = "email" type = "string"/> </class></hibernate-mapping>
