Class BeanValidationPostProcessor
- java.lang.Object
- org.springframework.validation.beanvalidation.BeanValidationPostProcessor
- All Implemented Interfaces:
BeanPostProcessor
,InitializingBean
public class BeanValidationPostProcessor extends Object implements BeanPostProcessor, InitializingBean
SimpleBeanPostProcessor
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 Detail
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.
- See Also:
ValidatorFactory.getValidator()
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 containingBeanFactory
after it has set all bean properties and satisfiedBeanFactoryAware
,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.

in interfaceInitializingBean
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'safterPropertiesSet
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.- Specified by:
postProcessBeforeInitialization
in interfaceBeanPostProcessor
- Parameters:
bean
- the new bean instancebeanName
- 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- See Also:
InitializingBean.afterPropertiesSet()
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'safterPropertiesSet
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.- Specified by:
postProcessAfterInitialization
in interfaceBeanPostProcessor
- Parameters:
bean
- the new bean instancebeanName
- 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- See Also:
InitializingBean.afterPropertiesSet()
,FactoryBean
doValidate
protected void doValidate(Object bean)
Perform validation of the given bean.- Parameters:
bean
- the bean instance to validate- See Also:
