Class PersistenceExceptionTranslationInterceptor

java.lang.Object

org.springframework.dao.support.PersistenceExceptionTranslationInterceptor

All Implemented Interfaces:

Advice, Interceptor, MethodInterceptor, org.springframework.beans.factory.Aware, org.springframework.beans.factory.BeanFactoryAware, org.springframework.beans.factory.InitializingBean

public class PersistenceExceptionTranslationInterceptor
extends Object
implements MethodInterceptor, org.springframework.beans.factory.BeanFactoryAware, org.springframework.beans.factory.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 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(org.springframework.beans.factory.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)

setAlwaysTranslate

public void setAlwaysTranslate(boolean alwaysTranslate)

Specify whether to always translate the exception ("true"), or whether throw the raw exception when declared, i.e. when the originating method signature's exception declarations allow for the raw exception to be thrown ("false").

Default is "false". Switch this flag to "true" in order to always translate applicable exceptions, independent from the originating method signature.

Note that the originating method does not have to declare the specific exception. Any base class will do as well, even throws Exception: As long as the originating method does explicitly declare compatible exceptions, the raw exception will be rethrown. If you would like to avoid throwing raw exceptions in any case, switch this flag to "true".

setBeanFactory

public void setBeanFactory(org.springframework.beans.factory.BeanFactory beanFactory)
                    throws org.springframework.beans.BeansException

Specified by:

setBeanFactory in interface org.springframework.beans.factory.BeanFactoryAware

Throws:

org.springframework.beans.BeansException

afterPropertiesSet

public void afterPropertiesSet()

Specified by:

afterPropertiesSet in interface org.springframework.beans.factory.InitializingBean

detectPersistenceExceptionTranslators

protected PersistenceExceptionTranslator detectPersistenceExceptionTranslators(org.springframework.beans.factory.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

invoke

public Object invoke(MethodInvocation mi)
              throws Throwable

Specified by:

invoke in interface MethodInterceptor

Throws:

Throwable
