+Configuration Examples
+
+* Configuration through a hibernate.properties-File
+
+ The most simple way to configure the plugin is, to put all the
+ hibernate-configuration in a <<hibernate.properties>>-file on your
+ classpath. Put the file in the <<<resources>>>-folder. Maven will put
+ it in the <<<class>>>-folder of your webapp, where it will be picked up
+ by this plugin as well as by Hibernate 4.
+
+ Doing so, the only additionally configuration needed, to activat the plugin
+ is the following entry in the <<<plugins>>>-section of your <<<pom.xml>>>:
+
+---------------
+<plugin>
+ <groupId>de.juplo</groupId>
+ <artifactId>hibernate4-maven-plugin</artifactId>
+ <version>${project.version}</version>
+ <executions>
+ <execution>
+ <goals>
+ <goal>export</goal>
+ </goals>
+ </execution>
+ </executions>
+</plugin>
+---------------
+
+ But be aware, that in this case the database-url, that is
+ build in the application is the same that is used while testing, where
+ the database is droped and recreated by the plugin.
+ <<<So, you should never fire up this configuration on your production
+ system, or your database might be erased!>>>
+
+ Hence, you should specify a different url for testing like in the
+ following snippet:
+
+---------------
+<plugin>
+ <groupId>de.juplo</groupId>
+ <artifactId>hibernate4-maven-plugin</artifactId>
+ <version>${project.version}</version>
+ <executions>
+ <execution>
+ <goals>
+ <goal>export</goal>
+ </goals>
+ </execution>
+ </executions>
+ <configuration>
+ <url><![CDATA[jdbc:mysql://localhost/test-db]]></url>
+ </configuration>
+</plugin>
+---------------
+
+ Configuration properties, that are set in the <<<configuration>>>-section
+ of the plugin-configuration cannnot be overwritten elsewere (for details
+ see {{Configuration-Method-Precedence}}).
+ You never can overwrite them by accident when specifying a property on
+ the commandline or in your <<<settings.xml>>>.
+
+* Configuration through maven-properties
+
+ Alternatively, it is possible, to configure the plugin via maven-properties.
+ Each relevant configuration-option has a corresponding maven-property
+ (for a full list see the {{{./export-mojo.html} Documentation of the export-Mojo}}).
+ These are named after the
+ {{{http://docs.jboss.org/hibernate/orm/4.1/manual/en-US/html_single/#configuration-hibernatejdbc} Hibernate JDBC Properties}}:
+
+ * <<<hibernate.connection.driver_class>>>
+
+ * <<<hibernate.dialect>>>
+
+ * <<<hibernate.connection.url>>>
+
+ * <<<hibernate.connection.username>>>
+
+ * <<<hibernate.connection.password>>>
+
+ So, instead of writing the hibernate-configuration in the properties-file,
+ like above, you could put it in the <<<properties>>>-section of your
+ <<<pom.xml>>>.
+
+ Thogether with the plugin-definition from above, the following would
+ be a complete configuration (again, the database-url was overwritten in
+ the plugin-configuration, to be sure to have a separate database for
+ testing):
+
+---------------
+<properties>
+ <hibernate.connection.driver_class>org.hsqldb.jdbcDriver</hibernate.connection.driver_class>
+ <hibernate.dialect>org.hibernate.dialect.HSQLDialect</hibernate.dialect>
+ <hibernate.connection.url><![CDATA[jdbc:hsqldb:res:org.my.path.production_db]]></hibernate.connection.url>
+ <hibernate.connection.username>sa</hibernate.connection.username>
+ <hibernate.connection.password></hibernate.connection.password>
+</properties>
+
+...
+
+<plugins>
+
+ ...
+
+ <plugin>
+ <groupId>de.juplo</groupId>
+ <artifactId>hibernate4-maven-plugin</artifactId>
+ <version>${project.version}</version>
+ <executions>
+ <execution>
+ <goals>
+ <goal>export</goal>
+ </goals>
+ </execution>
+ </executions>
+ <configuration>
+ <url><![CDATA[jdbc:hsqldb:target/db/testdb;shutdown=true]]></url>
+ </configuration>
+ </plugin>
+
+<plugins>
+---------------
+
+* Configuration through the plugin-configuration
+
+ A third way for configuring the plugin is the plugin-configuration.
+ The relevant configuration-parameters are:
+
+ * <<<driverClassName>>>
+
+ * <<<hibernateDialect>>>
+
+ * <<<url>>>
+
+ * <<<username>>>
+
+ * <<<password>>>
+
+ The equivalent of the configuration from the last section would look
+ like this:
+
+---------------
+<plugin>
+ <groupId>de.juplo</groupId>
+ <artifactId>hibernate4-maven-plugin</artifactId>
+ <version>${project.version}</version>
+ <executions>
+ <execution>
+ <goals>
+ <goal>export</goal>
+ </goals>
+ </execution>
+ </executions>
+ <configuration>
+ <driverClassName>org.hsqldb.jdbcDriver</driverClassName>
+ <hibernateDialect>org.hibernate.dialect.HSQLDialect</hibernateDialect>
+ <url><![CDATA[jdbc:hsqldb:target/db/fotos;shutdown=true]]></url>
+ <username>sa</username>
+ <password></password>
+ </configuration>
+</plugin>
+---------------
+
+ There are some seldom used parameters, that can only be configured throug
+ this method:
+
+ * <<delimiter>> the delimiter used in the generated sql-script
+
+ * <<format>> wether the generated sql-script is formatted, or not
+
+ * <<hibernateProperties>> name of the hibernate-properties-file
+
+ * <<outputFile>> name of the generated sql-script
+
+ * <<target>> create database or generate sql-script or both
+
+ * <<type>> create or drop the database or do both or nothing
+ (just validate the annotation-configuration)
+
+ For explanations, see the
+ {{{./export-mojo.html} Documentation of the export-Mojo}}.
+
+{Configuration-Method-Precedence}
+
+ The configuration is gathered in a fix order:
+
+ [[1]] <<<hibernate.properties>>>
+
+ [[2]] maven-properties
+
+ [[3]] plugin-configuration
+
+ If you are in doubt about where a configuration-value comes from, run
+ maven with the {{{./debugging.html}debug-output}} enabled: <<<mvn -X hibernate4:export>>>
+ and be aware, that maven-properties can be overwitten on the command-line,
+ in your <<<~/.m2/settings.xml>>> and in a profile.
+
+ The plugin-configuration comes last and overwrites everything else.
+ That way, you can be sure, that a configuration-value, that is
+ specified in the plugin-configuration will never be overwritten by any
+ other configuration-method.
+
+
+ If you realy need to overwrite plugin-configuration-values with
+ maven-properties, you can use maven-properties in the plugin-configuration:
+
+----------------
+<plugin>
+ <groupId>de.juplo</groupId>
+ <artifactId>hibernate4-maven-plugin</artifactId>
+ <version>${project.version}</version>
+ <executions>
+ <execution>
+ <goals>
+ <goal>export</goal>
+ </goals>
+ </execution>
+ </executions>
+ <configuration>
+ <password>${my-password-property}</password>
+ </configuration>
+</plugin>
