Skip a database column so that is does not show up in generated schema
As seen in the previous Intermediate example, a user can provide a custom NamingConventionTransformer
.
The following NamingConventionTransformer
will:
- name the schema element 'simple'
- make the element names lowercase
- skip the SINCE field
package foo.bar.blah; import org.eclipse.persistence.tools.dbws.DefaultNamingConventionTransformer; import static org.eclipse.persistence.tools.dbws.NamingConventionTransformer.ElementStyle.ELEMENT; import static org.eclipse.persistence.tools.dbws.NamingConventionTransformer.ElementStyle.NONE; public class MyNamingConventionTransformer extends DefaultNamingConventionTransformer { @Override public String generateSchemaAlias(String tableName) { return super.generateSchemaAlias("simple"); } @Override public String generateElementAlias(String originalElementName) { return super.generateElementAlias(originalElementName.toLowerCase()); } @Override public ElementStyle styleForElement(String elementName) { if ("since".equalsIgnoreCase(elementName)) { return NONE; } return ELEMENT; } }
