Class BeanValidationPostProcessor

java.lang.Object
org.springframework.validation.beanvalidation.BeanValidationPostProcessor
All Implemented Interfaces:
BeanPostProcessor, InitializingBean
public class BeanValidationPostProcessor extends Object implements BeanPostProcessor, InitializingBean
Simple BeanPostProcessor that checks JSR-303 constraint annotations in Spring-managed beans, throwing an initialization exception in case of constraint violations right before calling the bean's init method (if any).
Since:
3.0

  • Method Details

    • setValidator

      public void setValidator(Validator validator)
      Set the JSR-303 Validator to delegate to for validating beans.

      Default is the default ValidatorFactory's default Validator.

    • setValidatorFactory

      public void setValidatorFactory(ValidatorFactory validatorFactory)
      Set the JSR-303 ValidatorFactory to delegate to for validating beans, using its default Validator.

      Default is the default ValidatorFactory's default Validator.

    • setAfterInitialization

      public void setAfterInitialization(boolean afterInitialization)
      Choose whether to perform validation after bean initialization (i.e. after init methods) instead of before (which is the default).

      Default is "false" (before initialization). Switch this to "true" (after initialization) if you would like to give init methods a chance to populate constrained fields before they get validated.

    • afterPropertiesSet

      public void afterPropertiesSet()
      Description copied from interface: 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.

      Specified by:
      afterPropertiesSet in interface InitializingBean

    • postProcessBeforeInitialization

      public Object postProcessBeforeInitialization(Object bean, String beanName) throws BeansException
      Description copied from interface: BeanPostProcessor
      Apply this BeanPostProcessor to the given new bean instance before any bean initialization callbacks (like InitializingBean's afterPropertiesSet or a custom init-method). The bean will already be populated with property values. The returned bean instance may be a wrapper around the original.

      The default implementation returns the given bean as-is.

      Specified by:
      postProcessBeforeInitialization in interface BeanPostProcessor
      Parameters:
      bean - the new bean instance
      beanName - the name of the bean
      Returns:
      the bean instance to use, either the original or a wrapped one; if null, no subsequent BeanPostProcessors will be invoked
      Throws:
      BeansException - in case of errors

    • postProcessAfterInitialization

      public Object postProcessAfterInitialization(Object bean, String beanName) throws BeansException
      Description copied from interface: BeanPostProcessor
      Apply this BeanPostProcessor to the given new bean instance after any bean initialization callbacks (like InitializingBean's afterPropertiesSet or a custom init-method). The bean will already be populated with property values. The returned bean instance may be a wrapper around the original.

      In case of a FactoryBean, this callback will be invoked for both the FactoryBean instance and the objects created by the FactoryBean (as of Spring 2.0). The post-processor can decide whether to apply to either the FactoryBean or created objects or both through corresponding bean instanceof FactoryBean checks.

      This callback will also be invoked after a short-circuiting triggered by a InstantiationAwareBeanPostProcessor.postProcessBeforeInstantiation(java.lang.Class<?>, java.lang.String) method, in contrast to all other BeanPostProcessor callbacks.

      The default implementation returns the given bean as-is.

      Specified by:
      postProcessAfterInitialization in interface BeanPostProcessor
      Parameters:
      bean - the new bean instance
      beanName - the name of the bean
      Returns:
      the bean instance to use, either the original or a wrapped one; if null, no subsequent BeanPostProcessors will be invoked
      Throws:
      BeansException - in case of errors

    • doValidate

      protected void doValidate(Object bean)
      Perform validation of the given bean.
      Parameters:
      bean - the bean instance to validate
