类 PersistenceExceptionTranslationInterceptor

构造器详细资料

• PersistenceExceptionTranslationInterceptor

  public PersistenceExceptionTranslationInterceptor()

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

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

• PersistenceExceptionTranslationInterceptor

  public PersistenceExceptionTranslationInterceptor​(PersistenceExceptionTranslator pet)

  Create a new PersistenceExceptionTranslationInterceptor for the given PersistenceExceptionTranslator.

  参数:

  pet - the PersistenceExceptionTranslator to use

• PersistenceExceptionTranslationInterceptor

  public PersistenceExceptionTranslationInterceptor​(ListableBeanFactory beanFactory)

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

  参数:

  beanFactory - the ListableBeanFactory to obtaining all PersistenceExceptionTranslators from

方法详细资料

• 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.

  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​(BeanFactory beanFactory)
                      throws BeansException

  从接口复制的说明: 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.

  指定者:

  setBeanFactory 在接口中 BeanFactoryAware

  参数:

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

  抛出:

  BeansException - in case of initialization errors

  BeanInitializationException

• afterPropertiesSet

  public void afterPropertiesSet()

  从接口复制的说明: InitializingBean
  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.

  指定者:

  afterPropertiesSet 在接口中 InitializingBean

• invoke

  public Object invoke​(MethodInvocation mi)
                throws Throwable

  从接口复制的说明: MethodInterceptor
  Implement this method to perform extra treatments before and after the invocation. Polite implementations would certainly like to invoke Joinpoint.proceed().

  指定者:

  invoke 在接口中 MethodInterceptor

  参数:

  mi - the method invocation joinpoint

  返回:

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

  抛出:

  Throwable - if the interceptors or the target object throws an exception

• detectPersistenceExceptionTranslators

  protected PersistenceExceptionTranslator detectPersistenceExceptionTranslators​(ListableBeanFactory bf)

  Detect all PersistenceExceptionTranslators in the given BeanFactory.

  参数:

  bf - the ListableBeanFactory to obtain PersistenceExceptionTranslators from

  返回:

  a chained PersistenceExceptionTranslator, combining all PersistenceExceptionTranslators found in the given bean factory
