Recently while working on a project, I needed to get the table names associated with a particular domain as I needed to perform complex join operations on a particular table. The database that my team was working on was a legacy database. The domains that were created were mapped to particular tables to provide backward compatibility with the existing system’s database and, hence the table names were specified in the mapping closure. Now I needed a way to get the names of the tables that were associated with a particular domain.
The SessionFactoryProxy can be directly used to get the table name associated with the domain. So the code is as follows:
import org.hibernate.metadata.ClassMetadata import org.codehaus.groovy.grails.orm.hibernate.cfg.GrailsDomainBinder import org.codehaus.groovy.grails.commons.ApplicationHolder Class clazz = Class.forName("com.intelligrape.domain.Album", true, Thread.currentThread().getContextClassLoader()) String mappedTable def sessionFactory = ApplicationHolder.application.mainContext.getBean("sessionFactory") ClassMetadata hibernateMetaClass = sessionFactory.getClassMetadata(clazz) mappedTable = hibernateMetaClass.getTableName() println "Mapped table name: " + mappedTable
Now the above modified code returns the table name associated with a domain.
