## Class HibernateExceptionTranslator

- java.lang.Object
- - org.springframework.orm.hibernate3.HibernateExceptionTranslator

All Implemented Interfaces:
  PersistenceExceptionTranslator

Direct Known Subclasses:
  AbstractSessionFactoryBean

    public class HibernateExceptionTranslator
    extends Object
    implements PersistenceExceptionTranslator

`PersistenceExceptionTranslator` capable of translating `HibernateException` instances to Spring's `DataAccessException` hierarchy.

Extended by `LocalSessionFactoryBean`, so there is no need to declare this translator in addition to a `LocalSessionFactoryBean`.

When configuring the container with `@Configuration` classes, a `@Bean` of this type must be registered manually.

Constructor and Description
`HibernateExceptionTranslator()`

### Method Summary

Methods
`protected DataAccessException` `convertHibernateAccessException(HibernateException ex)` Convert the given HibernateException to an appropriate exception from the `org.springframework.dao` hierarchy.
`void` `setJdbcExceptionTranslator(SQLExceptionTranslator jdbcExceptionTranslator)` Set the JDBC exception translator for the SessionFactory, exposed via the PersistenceExceptionTranslator interface.
`DataAccessException` `translateExceptionIfPossible(RuntimeException ex)` Translate the given runtime exception thrown by a persistence framework to a corresponding exception from Spring's generic DataAccessException hierarchy, if possible.

### Constructor Detail

#### HibernateExceptionTranslator

    public HibernateExceptionTranslator()

### Method Detail

#### setJdbcExceptionTranslator

    public void setJdbcExceptionTranslator(SQLExceptionTranslator jdbcExceptionTranslator)

Set the JDBC exception translator for the SessionFactory, exposed via the PersistenceExceptionTranslator interface.

Applied to any SQLException root cause of a Hibernate JDBCException, overriding Hibernate's default SQLException translation (which is based on Hibernate's Dialect for a specific target database).

Parameters:
  `jdbcExceptionTranslator` - the exception translator
See Also:
  `SQLException`, `JDBCException`, `SQLErrorCodeSQLExceptionTranslator`, `SQLStateSQLExceptionTranslator`, `PersistenceExceptionTranslator`

#### translateExceptionIfPossible

    public DataAccessException translateExceptionIfPossible(RuntimeException ex)

Description copied from interface: `PersistenceExceptionTranslator`
Translate the given runtime exception thrown by a persistence framework to a corresponding exception from Spring's generic DataAccessException hierarchy, if possible.

Do not translate exceptions that are not understand by this translator: for example, if coming from another persistence framework, or resulting from user code and unrelated to persistence.

Of particular importance is the correct translation to DataIntegrityViolationException, for example on constraint violation. Implementations may use Spring JDBC's sophisticated exception translation to provide further information in the event of SQLException as a root cause.

Specified by:
  `translateExceptionIfPossible` in interface `PersistenceExceptionTranslator`
Parameters:
  `ex` - a RuntimeException thrown
Returns:
  the corresponding DataAccessException (or `null` if the exception could not be translated, as in this case it may result from user code rather than an actual persistence problem)
See Also:
  `DataIntegrityViolationException`, `SQLExceptionTranslator`

#### convertHibernateAccessException

    protected DataAccessException convertHibernateAccessException(HibernateException ex)

Convert the given HibernateException to an appropriate exception from the `org.springframework.dao` hierarchy.

Will automatically apply a specified SQLExceptionTranslator to a Hibernate JDBCException, else rely on Hibernate's default translation.

Parameters:
  `ex` - HibernateException that occured
Returns:
  a corresponding DataAccessException
