使用工具:
hbm2java
hbm2ddl

hbm2java的属性介绍:
<hbm2ddl
 export="true|false"                                  (1)
 update="true|false"                                  (2)
 drop="true|false"                                    (3)
 create="true|false"                                  (4)
 outputfilename="filename.ddl"                        (5)
 delimiter=";"                                        (6)
 format="true|false"                                  (7)
 haltonerror="true|false"			      (8)
>
(1)

export (default: true): Execute the generated statements against the database
(2)

update(default: false): Try and create an update script representing the "delta" between what is in the database and what the mappings specify. Ignores create/update attributes. (Do *not* use against production databases, no guarantees at all that the proper delta can be generated nor that the underlying database can actually execute the needed operations)
(3)

drop (default: false): Output will contain drop statements for the tables, indices & constraints
(4)

create (default: true): Output will contain create statements for the tables, indices & constraints
(5)

outputfilename (Optional): If specified the statements will be dumped to this file.
(6)

delimiter (default: ";"): What delimter to use to separate statements
(7)

format (default: false): Apply basic formatting to the statements.
(8)

haltonerror (default: false): Halt build process if an error occurs.


hbm2java的属性介绍:
<hbm2java
 jdk5="true|false"                                    (1)
 ejb3="true|false"                                    (2)
>
(1)

jdk (default: false): Code will contain JDK 5 constructs such as generics and static imports
(2)

ejb3 (default: false): Code will contain EJB 3 features, e.g. using annotations from javax.persistence and org.hibernate.annotations
