Hibernate Tools是Hibernate官方提供的。该插件要安装跟Eclipse的版本有关系。反转引擎是插件的功能之一。
插件配置和使用的步骤：
a. 在pom.xml中引入和配置hibernate3-maven-plugin插件，并引入Hibernate Tools的依赖项目。 配置hibernate3-maven-plugin插件：
<plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>hibernate3-maven-plugin</artifactId> <version>2.2</version> <!-- <groupId>com.dayatang.maven.mojo</groupId> <artifactId>hibernate3-maven-plugin</artifactId> <version>2.9</version> --> <configuration> <components> <component> <name>hbm2hbmxml</name> <implementation>jdbcconfiguration</implementation> <outputDirectory>target/generated-resources/hibernate</outputDirectory> </component> <component> <name>hbm2java</name> <implementation>jdbcconfiguration</implementation> <outputDirectory>target/generated-sources/hibernate</outputDirectory> </component> </components> <componentPRoperties> <!-- 反转规则配置文件 --> <revengfile>src/main/resources/reveng.xml</revengfile> <!-- Hibernate数据库连接属性文件 --> <propertyfile>src/main/resources/hibernate.properties</propertyfile> <!-- 生成实体类默认包 --> <packagename>cn.aric.bos.domain</packagename> <jdk5>true</jdk5> <!-- 如果设置为true则生成JPA注解，若设置为false则生成hbml.xml --> <ejb3>true</ejb3> </componentProperties> </configuration> <dependencies> <dependency> <groupId>cglib</groupId> <artifactId>cglib-nodep</artifactId> <version>2.2.2</version> </dependency> <dependency> <groupId>com.Oracle</groupId> <artifactId>ojdbc14</artifactId> <version>${oracle.version}</version> <scope>runtime</scope> </dependency> </dependencies> </plugin>b. hibernate3-maven-plugin插件底层需要依赖于Hibernate Tools。 注意包冲突问题，可以排除低版本的jar。配置Hibernate Tools:
<properties> <hibernate-tools.version>3.6.0.CR1</hibernate-tools.version> </properties> <dependencies> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-tools</artifactId> <version>${hibernate-tools.version}</version> </dependency> </dependencies>hibernate.connection.driver_class=oracle.jdbc.driver.OracleDriver hibernate.connection.url=jdbc:oracle:thin:@localhost:1521:study hibernate.connection.username=BOS hibernate.connection.passWord=bos
建立和配置src/main/resources/reveng.xml文件（反转规则文件，独立规则语法，myeclipse的反转引擎中也会生成该文件）。注意：方案名和表名必须大写!否则无法反转成功！
