Class PersistenceExceptionTranslationInterceptor

java.lang.Object
org.springframework.dao.support.PersistenceExceptionTranslationInterceptor
All Implemented Interfaces:
org.aopalliance.aop.Advice, org.aopalliance.intercept.Interceptor, org.aopalliance.intercept.MethodInterceptor, org.springframework.beans.factory.Aware, org.springframework.beans.factory.BeanFactoryAware, org.springframework.beans.factory.InitializingBean
public class PersistenceExceptionTranslationInterceptor extends Object implements org.aopalliance.intercept.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

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

    • PersistenceExceptionTranslationInterceptor

      public PersistenceExceptionTranslationInterceptor(PersistenceExceptionTranslator pet)
      Create a new PersistenceExceptionTranslationInterceptor for the given PersistenceExceptionTranslator.
      Parameters:
      pet - 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 Details

    • 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:

    • 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 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".

    • detectPersistenceExceptionTranslators

      protected PersistenceExceptionTranslator detectPersistenceExceptionTranslators(org.springframework.beans.factory.ListableBeanFactory bf)
      Detect all PersistenceExceptionTranslators in the given BeanFactory.
      Parameters:
      bf - the ListableBeanFactory to obtain PersistenceExceptionTranslators from
      Returns:
      a chained PersistenceExceptionTranslator, combining all PersistenceExceptionTranslators found in the given bean factory
