I'm trying to configure hbm2java
with maven to generate POJO classes and DAO objects. One of the issues I'm dealing with is package names aren't generated. I'm using the following pom for that:
<execution>
<id>hbm2java</id>
<phase>generate-sources</phase>
<goals>
<goal>hbm2java</goal>
</goals>
<inherited>false</inherited>
<configuration>
<components>
<component>
<name>hbm2java</name>
<implementation>configuration</implementation>
</component>
</components>
<componentProperties>
<packagename>package.name</packagename>
<configurationfile>target/hibernate3/generated-mappings/hibernate.cfg.xml</configurationfile>
</componentProperties>
</configuration>
</execution>
Yet the generated code begins with the following:
// default package
// Generated 2010-05-17 13:11:51 by Hibernate Tools 3.2.2.GA
/**
* Messages generated by hbm2java
*/
public class Messages implements java.io.Serializable {
Is there a way to force maven to generate the package part as defined in packagename?
Update:
Here is my hibernate.cfg.xml, also automatically generated by hibernate-tools (hbm2cfgxml):
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<property name="hibernate.c3p0.max_statements">50</property>

<property name="hibernate.c3p0.timeout">1800</property>

<property name="hibernate.dialect">org.hibernate.dialect.PostgreSQLDialect</property>
<mapping resource="package/name/Messages.hbm.xml" />
</session-factory>
</hibernate-configuration>
Just in case, here is a working configuration of the hibernate3-maven-plugin for a bottom-up approach:
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>hibernate3-maven-plugin</artifactId>
<version>2.2</version>
<executions>
<execution>
<id>generate-xml-files</id>
<phase>generate-resources</phase>
<goals>
<goal>hbm2hbmxml</goal>
<goal>hbm2cfgxml</goal>
</goals>
</execution>
<execution>
<id>generate-entities</id>
<phase>generate-sources</phase>
<goals>
<goal>hbm2java</goal>
</goals>
</execution>
</executions>
<configuration>
<components>
<component>
<name>hbm2hbmxml</name>
<implementation>jdbcconfiguration</implementation>
<outputDirectory>target/classes</outputDirectory>
</component>
<component>
<name>hbm2cfgxml</name>
<implementation>jdbcconfiguration</implementation>
<outputDirectory>target/classes</outputDirectory>
</component>
<component>
<name>hbm2java</name>
<implementation>configuration</implementation>
<outputDirectory>target/generated-sources/hibernate3</outputDirectory>
</component>
</components>
<componentProperties>
<propertyfile>src/main/resources/database.properties</propertyfile>
<jdk5>true</jdk5>
<ejb3>false</ejb3>
<packagename>com.mycompany.myapp</packagename>

<haltonerror>true</haltonerror>
</componentProperties>
</configuration>
<dependencies>
<dependency>
<groupId>org.apache.derby</groupId>
<artifactId>derby</artifactId>
<version>10.5.3.0_1</version>
</dependency>
</dependencies>
</plugin>
And here is the content of my src/main/database.properties
file:
hibernate.connection.driver_class=org.apache.derby.jdbc.EmbeddedDriver
hibernate.connection.url=jdbc:derby:./derbyDBs/EMPLDB
hibernate.connection.username=APP
hibernate.connection.password=APP
hibernate.dialect=org.hibernate.dialect.DerbyDialect
#workaround for http://opensource.atlassian.com/projects/hibernate/browse/HBX-1145
hibernate.connection.autocommit=true
This setup:
*.hbm.xml
in target/classes
(with the package) during generate-resources
.hibernate.cfg.xml
in target/classes
with entries for the mapping files.target/generated-sources/hibernate3
(I recommend following the target/generated-sources/<tool>
convention for generated sources so that they will get auto-detected by IDEs).Here is a the result of clean compile
against a sample database with two tables:
$ mvn clean compile ... $ tree target/ target/ ├── classes │ ├── com │ │ └── mycompany │ │ └── myapp │ │ ├── Department.class │ │ ├── Department.hbm.xml │ │ ├── Employee.class │ │ └── Employee.hbm.xml │ ├── database.properties │ └── hibernate.cfg.xml └── generated-sources └── hibernate3 └── com └── mycompany └── myapp ├── Department.java └── Employee.java
