好吧，如果您不想混合使用Ant和Maven ，则可以使用Maven Hibernate3插件（在IMO中，这是个好主意）。它有一个hbm2java目标，默认情况下与该generate- sources阶段绑定。有关更多详细信息，请访问Mojo的网站，但该插件的设置可能类似于以下内容：
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>hibernate3-maven-plugin</artifactId>
<version>2.2</version>
<executions>
<execution>
<phase>generate-sources</phase>
<goals>
<goal>hbm2java</goal>
</goals>
</execution>
</executions>
<configuration>
<components>
<component>
<name>hbm2java</name>
<implementation>configuration</implementation>
<outputDirectory>target/generated-sources/hibernate3</outputDirectory>
</component>
</components>
<componentProperties>
<drop>true</drop>
<jdk5>true</jdk5>
<configurationfile>/src/main/resources/hibernate.cfg.xml</configurationfile>
</componentProperties>
</configuration>
</plugin>
插件实际上.hbm.xml在target/classes寻找生成Java源文件。因此，如果将映射文件放在中src/main/resources，它们将在插件调用target/classes的process- resources阶段被复制到其中，并且一切正常。我刚刚使用以下示例项目对此进行了测试：
Maven的hibernate3测试用例
|-pom.xml
`-src
|-主要
| |-Java
| `-资源
| |-Person.hbm.xml
| `-hibernate.cfg.xml
`-测试
`-Java
在pom.xml几乎是空的，它只是包含了上面和一个JUnit依赖看到的插件配置。该hibernate.cfg.xml包含：
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<!-- Database connection settings -->
<property name="connection.driver_class">org.apache.derby.jdbc.ClientDriver</property>
<property name="connection.url">jdbc:derby://localhost:1527/mydatabase</property>
<property name="connection.username">app</property>
<property name="connection.password">app</property>
<!-- JDBC connection pool (use the built-in) -->
<property name="connection.pool_size">1</property>
<!-- sql dialect -->
<property name="dialect">org.hibernate.dialect.DerbyDialect</property>
<!-- Echo all executed sql to stdout -->
<property name="show_sql">false</property>
<!-- Mapping files -->
<mapping resource="Person.hbm.xml" />
</session-factory>
</hibernate-configuration>
并Person.hbm.xml如下所示：
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-mapping
PUBLIC "-//Hibernate/Hibernate Mapping DTD//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping>
<class name="Person" table="person">
<id name="id" type="int">
<generator class="increment" />
</id>
<property name="name" column="cname" type="string" />
</class>
</hibernate-mapping>
使用此配置，运行mvn install生成Person.java如下所示：
$ cat target/generated-sources/hibernate3/Person.java
// default package
// Generated Dec 14, 2009 2:19:22 PM by Hibernate Tools 3.2.2.GA
/**
* Person generated by hbm2java
*/
public class Person implements java.io.Serializable {
private int id;
private String name;
public Person() {
}
public Person(String name) {
this.name = name;
}
public int getId() {
return this.id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return this.name;
}
public void setName(String name) {
this.name = name;
}
}
一切都按说明进行。
