Hi,
can any one tell me how
to force maven
to precede mapping .hbm.
xml files in the automatically generated hibernate.cfg.
xml file with package path?
My general idea is, I'd like
to use hibernate-tools via maven
to generate the persistence layer for my application. So, I need the hibernate.cfg.
xml, then all my_table_names.hbm.
xml and at the end the POJO's generated. Yet, the hbm2java goal won't work as I put *.hbm.
xml files into the src/main/resources/package/path/ folder but hbm2cfgxml specifies the mapping files only by table name, i.e.:
<mapping resource="MyTableName.hbm.
xml" />
So the big question is: how can I configure hbm2cfgxml so that hibernate.cfg.
xml looks like below:
<mapping resource="package/path/MyTableName.hbm.
xml" />
My pom.
xml looks like this at the moment:
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>hibernate3-maven-plugin</artifactId>
<version>2.2</version>
<executions>
<execution>
<id>hbm2cfgxml</id>
<phase>generate-sources</phase>
<goals>
<goal>hbm2cfgxml</goal>
</goals>
<inherited>false</inherited>
<configuration>
<components>
<component>
<name>hbm2cfgxml</name>
<implemetation>jdbcconfiguration</implementation>
<outputDirectory>src/main/resources/</outputDirectory>
</component>
</components>
<componentProperties>
<packagename>package.path</packageName>
<configurationFile>src/main/resources/hibernate.cfg.xml</configurationFile>
</componentProperties>
</configuration>
</execution>
</executions>
</plugin>
And then the second question: is there a way
to tell maven
to copy resources
to the target folder before executing hbm2java? At the moment I'm using
mvn clean resources:resources generate-sources
for that, but there must be a better way.
Thanks for any help.
Update:
@Pascal: Thank you for your help. The path
to mappings works fine now, I don't know what was wrong before, though. Maybe there is some issue with writing
to hibernate.cfg.
xml while reading database config from it (though the file gets updated).
I've deleted the file hibernate.cfg.
xml, replaced it with database.properties and run the goals hbm2cfgxml and hbm2hbmxml. I also don't use the outputDirectory nor configurationfile in those goals anymore.
As a result the files hibernate.cfg.
xml and all *.hbm.
xml are being generated into my target/hibernate3/generated-mappings/ folder, which is the default value. Then I updated the hbm2java goal with the following:
<componentProperties>
<packagename>package.name</packagename>
<configurationfile>target/hibernate3/generated-mappings/hibernate.cfg.xml</configurationfile>
</componentProperties>
But then I get the following:
[INFO] --- hibernate3-maven-plugin:2.2:hbm2java (hbm2java) @ project.persistence ---
[INFO] using configuration task.

xml not found
How do I deal with that? Of course I could add:
<outputDirectory>src/main/resources/package/name</outputDirectory>
to the hbm2hbmxml goal, but I think this is not the best approach, or is it? Is there a way
to keep all the generated code and resources away from the src/ folder?
I assume, the goal of this approach is not
to generate any sources into my src/main/java or /resources folder, but
to keep the generated code in the target folder. As I generally agree with this point of view, I'd like
to continue with that eventually executing hbm2dao and packaging the project
to be used as a generated persistence layer component from the business layer. Is this also what you meant?
