使用maven自动创建数据库,导入导出数据需要用到两个插件hibernate3-maven-plugin,dbunit-maven-plugin

hibernate3-maven-plugin,有7大功能,(这里我们只使用hbm2ddl,自动生成数据库)
The Maven Hibernate3 Plugin has seven goals.

hibernate3:hbm2cfgxml: Generates hibernate.cfg.xml
hibernate3:hbm2ddl: Generates database schema.
hibernate3:hbm2doc: Generates HTML documentation for the database schema.
hibernate3:hbm2hbmxml: Generates a set of hbm.xml files
hibernate3:hbm2java: Generates Java classes from set of *.hbm.xml files
hibernate3:schema-export: Creates SQL DDL file and generates the database schema from set of *.hbm.xml files
hibernate3:schema-update: Updates the database schema based on the set of *.hbm.xml files

dbunit-maven-plugin,可以实现数据库中数据的导入导出

dbunit:operation: Execute a database operation using an external dataset file.
dbunit:export: Export database tables into a dataset file.
dbunit:compare: Compare a dataset with database.


具体配置,(MYSQL为例)

在pom.xml中添加下面的代码

<build>

  <plugins>

       </executions>
   </plugin>
  
 

</plugins>

</build>

其中jdbc.properties 内容为

hibernate.dialect=org.hibernate.dialect.MySQLInnoDBDialect
hibernate.connection.username=root
hibernate.connection.password=
hibernate.connection.url=jdbc:mysql://localhost/projectStencil?createDatabaseIfNotExist=true&useUnicode=true&characterEncoding=utf-8
hibernate.connection.driver_class=com.mysql.jdbc.Driver



hibernate.cfg.xml 举例如下

<hibernate-configuration>
 <session-factory>
       <mapping class="com...dao.model.User" />

        ...

  </session-factory>
</hibernate-configuration>

sample-data.xml 为要导入数据库的数据

可以使用 mvn dbunit:export -Ddest=sample-data.xml 将数据库的数据导出来
