org.springframework.orm.jdo.DefaultJdoDialect

Default implementation of the {@link JdoDialect} interface.Updated to build on JDO 2.0 or higher, as of Spring 2.5. Used as default dialect by {@link JdoAccessor} and {@link JdoTransactionManager}.

Simply begins a standard JDO transaction in beginTransaction. Returns a handle for a JDO2 DataStoreConnection on getJdbcConnection. Calls the corresponding JDO2 PersistenceManager operation on flush Ignores a given query timeout in applyQueryTimeout. Uses a Spring SQLExceptionTranslator for exception translation, if applicable.

Note that, even with JDO2, vendor-specific subclasses are still necessary for special transaction semantics and more sophisticated exception translation. Furthermore, vendor-specific subclasses are encouraged to expose the native JDBC Connection on getJdbcConnection, rather than JDO2's wrapper handle.

This class also implements the PersistenceExceptionTranslator interface, as autodetected by Spring's PersistenceExceptionTranslationPostProcessor, for AOP-based translation of native exceptions to Spring DataAccessExceptions. Hence, the presence of a standard DefaultJdoDialect bean automatically enables a PersistenceExceptionTranslationPostProcessor to translate JDO exceptions. @author Juergen Hoeller @since 1.1 @see #setJdbcExceptionTranslator @see JdoAccessor#setJdoDialect @see JdoTransactionManager#setJdoDialect @see org.springframework.dao.annotation.PersistenceExceptionTranslationPostProcessor
