eclipse用Hibernate3-maven-plugin插件反转生成实体类

根据数据表生成实体和映射

Hibernate Tools插件

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。

Hibernate3-maven-plugin插件

插件配置和使用的步骤：

1.引入和配置hibernate3-maven-plugin插件

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>

2.建立和配置src/main/resources/hibernate.properties文件（hibernate核心属性配置）

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

3.建立和配置src/main/resources/reveng.xml文件

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！

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-reverse-engineering PUBLIC "-//Hibernate/Hibernate Reverse Engineering DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-reverse-engineering-3.0.dtd" >

<hibernate-reverse-engineering>
<!--match-schema:匹配（要反转的）方案名(用户名)， match-table：匹配表名（支持正则表达式，.*：任意字符串） -->
<schema-selection match-table="T_USER" match-schema="BOS"/>
<schema-selection match-table="T_BC_.*" match-schema="BOS"/>
<!-- 将BOS下的T_BC_DECIDEDZONE表反转生成bc包下的 DecidedZone类，主键策略为uuid-->
<table name="T_BC_DECIDEDZONE" schema="BOS"
class="cn.aric.bos.domain.bc.DecidedZone">
<primary-key>
<generator class="uuid"></generator>
</primary-key>
</table>
<table name="T_BC_REGION" schema="BOS"
class="cn.aric.bos.domain.bc.Region">
<primary-key>
<generator class="uuid"></generator>
</primary-key>
</table>
<table name="T_BC_STAFF" schema="BOS"
class="cn.aric.bos.domain.bc.Staff">
<primary-key>
<generator class="uuid"></generator>
</primary-key>
</table>
<table name="T_BC_SUBAREA" schema="BOS"
class="cn.aric.bos.domain.bc.Subarea">
<primary-key>
<generator class="uuid"></generator>
</primary-key>
</table>
<table name="T_USER" schema="BOS"
class="cn.aric.bos.domain.user.User">
<primary-key>
<generator class="uuid"></generator>
</primary-key>
</table>
</hibernate-reverse-engineering>

4. 执行maven命令：mvn hibernate3:hbm2java
