Hibernate connection Database

1. New Project
2. New Hibernate.xml Frame Right-click the project name->myeclipse->add hibernate
3. Create a new name to manipulate the database table. Hbm.xml module Right-click Src->new->xml (Basic Templates)--(change name) next-> (Create XMLFile from a DTD file ) next-> (Select XML Catalog entry) key found in Hibernate Mapping DTD 3.0 next->finish
4. Configure the name of the operation on the database table. Hbm.xml Module View Operations
(1). Right-click the module name->new->class Add name and table (database table name) properties

5. Configuring the Hibernate.xml Framework
Create a DB connection database
Select View Actions in Hibernate.xml
Select the DB database connection you created in DB driver and finally add in mappings Person.hbm.xml
6. Entity class operations that correspond to database tables
Mainly with the database table properties, fields consistent, right-click the space->source->generate Getters and Setters ... Add get and set
