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).

Constructor Summary

AccessConstructor and Description
public
PersistenceExceptionTranslationInterceptor()

Create a new PersistenceExceptionTranslationInterceptor.

public
PersistenceExceptionTranslationInterceptor(PersistenceExceptionTranslator
the PersistenceExceptionTranslator to use
pet)

Create a new PersistenceExceptionTranslationInterceptor for the given PersistenceExceptionTranslator.

public
PersistenceExceptionTranslationInterceptor(ListableBeanFactory
the ListableBeanFactory to obtaining all PersistenceExceptionTranslators from
beanFactory)

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

Method Summary

Modifier and TypeMethod and Description
public void
afterPropertiesSet()

Implements org.springframework.beans.factory.InitializingBean.afterPropertiesSet.

Invoked by the containing BeanFactory after it has set all bean properties and satisfied BeanFactoryAware, ApplicationContextAware etc.

This method allows the bean instance to perform validation of its overall configuration and final initialization when all bean properties have been set.

protected PersistenceExceptionTranslator

Returns:

a chained PersistenceExceptionTranslator, combining all PersistenceExceptionTranslators found in the given bean factory
detectPersistenceExceptionTranslators(ListableBeanFactory
the ListableBeanFactory to obtain PersistenceExceptionTranslators from
bf)

Detect all PersistenceExceptionTranslators in the given BeanFactory.

invoke(MethodInvocation
the method invocation joinpoint
mi)

Implements org.aopalliance.intercept.MethodInterceptor.invoke.

Implement this method to perform extra treatments before and after the invocation.
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").

public void
setBeanFactory(BeanFactory
owning BeanFactory (never null). The bean can immediately call methods on the factory.

Implements org.springframework.beans.factory.BeanFactoryAware.setBeanFactory.

Callback that supplies the owning factory to a bean instance.

Specify the PersistenceExceptionTranslator to use.

public Object invoke(MethodInvocation mi) throws Throwable

Implements org.aopalliance.intercept.MethodInterceptor.invoke.

Doc from org.aopalliance.intercept.MethodInterceptor.invoke.

Implement this method to perform extra treatments before and after the invocation. Polite implementations would certainly like to invoke Joinpoint#proceed().

Parameters
mi:MethodInvocation

the method invocation joinpoint

Returns:Object

the result of the call to Joinpoint#proceed(); might be intercepted by the interceptor

setAlwaysTranslateback to summary
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 of 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".

setBeanFactoryback to summary
public void setBeanFactory(BeanFactory beanFactory) throws BeansException

Implements org.springframework.beans.factory.BeanFactoryAware.setBeanFactory.

Doc from org.springframework.beans.factory.BeanFactoryAware.setBeanFactory.

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.

Parameters
beanFactory:BeanFactory

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

setPersistenceExceptionTranslatorback to summary
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.
