Class PersistenceExceptionTranslationInterceptor

java.lang.Object
  org.springframework.dao.support.PersistenceExceptionTranslationInterceptor

All Implemented Interfaces:

Advice, Interceptor, MethodInterceptor, BeanFactoryAware, InitializingBean

---

public class PersistenceExceptionTranslationInterceptor
extends Object
implements MethodInterceptor, BeanFactoryAware, InitializingBean

AOP Alliance MethodInterceptor that provides persistence exception translation based on a given PersistenceExceptionTranslator.

Delegates to the given PersistenceExceptionTranslator to translate a RuntimeException thrown into Spring's DataAccessException hierarchy (if appropriate). If the RuntimeException in question is declared on the target method, it is always propagated as-is (with no translation applied).

Since:

2.0

Constructor Summary
PersistenceExceptionTranslationInterceptor()           Create a new PersistenceExceptionTranslationInterceptor.
PersistenceExceptionTranslationInterceptor(ListableBeanFactory beanFactory)           Create a new PersistenceExceptionTranslationInterceptor, autodetecting PersistenceExceptionTranslators in the given BeanFactory.
PersistenceExceptionTranslationInterceptor(PersistenceExceptionTranslator persistenceExceptionTranslator)           Create a new PersistenceExceptionTranslationInterceptor for the given PersistenceExceptionTranslator.

 

Method Summary
void	afterPropertiesSet()           Invoked by a BeanFactory after it has set all bean properties supplied (and satisfied BeanFactoryAware and ApplicationContextAware).
protected  PersistenceExceptionTranslator	detectPersistenceExceptionTranslators(ListableBeanFactory beanFactory)           Detect all PersistenceExceptionTranslators in the given BeanFactory.
Object	invoke(MethodInvocation mi)
void	setBeanFactory(BeanFactory beanFactory)           Callback that supplies the owning factory to a bean instance.
void	setPersistenceExceptionTranslator(PersistenceExceptionTranslator pet)           Specify the PersistenceExceptionTranslator to use.

Constructor Detail

PersistenceExceptionTranslationInterceptor

public PersistenceExceptionTranslationInterceptor()

Create a new PersistenceExceptionTranslationInterceptor. Needs to be configured with a PersistenceExceptionTranslator afterwards.

See Also:

setPersistenceExceptionTranslator(org.springframework.dao.support.PersistenceExceptionTranslator)

---

PersistenceExceptionTranslationInterceptor

public PersistenceExceptionTranslationInterceptor(PersistenceExceptionTranslator persistenceExceptionTranslator)

Create a new PersistenceExceptionTranslationInterceptor for the given PersistenceExceptionTranslator.

Parameters:

persistenceExceptionTranslator - the PersistenceExceptionTranslator to use

---

PersistenceExceptionTranslationInterceptor

public PersistenceExceptionTranslationInterceptor(ListableBeanFactory beanFactory)

Create a new PersistenceExceptionTranslationInterceptor, autodetecting PersistenceExceptionTranslators in the given BeanFactory.

Parameters:

beanFactory - the ListableBeanFactory to obtaining all PersistenceExceptionTranslators from

Method Detail

setPersistenceExceptionTranslator

public void setPersistenceExceptionTranslator(PersistenceExceptionTranslator pet)

Specify the PersistenceExceptionTranslator to use.

Default is to autodetect all PersistenceExceptionTranslators in the containing BeanFactory, using them in a chain.

See Also:

detectPersistenceExceptionTranslators(org.springframework.beans.factory.ListableBeanFactory)

---

setBeanFactory

public void setBeanFactory(BeanFactory beanFactory)
                    throws BeansException

Description copied from interface: BeanFactoryAware

Callback that supplies the owning factory to a bean instance.

Invoked after the population of normal bean properties but before an initialization callback such as InitializingBean.afterPropertiesSet() or a custom init-method.

Specified by:

setBeanFactory in interface BeanFactoryAware

Parameters:

beanFactory - owning BeanFactory (never null). The bean can immediately call methods on the factory.

Throws:

BeansException - in case of initialization errors

See Also:

BeanInitializationException

---

afterPropertiesSet

public void afterPropertiesSet()

Description copied from interface: InitializingBean

Invoked by a BeanFactory after it has set all bean properties supplied (and satisfied BeanFactoryAware and ApplicationContextAware).

This method allows the bean instance to perform initialization only possible when all bean properties have been set and to throw an exception in the event of misconfiguration.

Specified by:

afterPropertiesSet in interface InitializingBean

---

detectPersistenceExceptionTranslators

protected PersistenceExceptionTranslator detectPersistenceExceptionTranslators(ListableBeanFactory beanFactory)

Detect all PersistenceExceptionTranslators in the given BeanFactory.

Parameters:

beanFactory - the ListableBeanFactory to obtaining all PersistenceExceptionTranslators from

Returns:

a chained PersistenceExceptionTranslator, combining all PersistenceExceptionTranslators found in the factory

See Also:

ChainedPersistenceExceptionTranslator

---

invoke

public Object invoke(MethodInvocation mi)
              throws Throwable

Specified by:

invoke in interface MethodInterceptor

Throws:

Throwable
