BeanValidationPostProcessor

extends Object
implements InitializingBean BeanPostProcessor
java.lang.Object
   ↳ org.springframework.validation.beanvalidation.BeanValidationPostProcessor

Class Overview

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).

Summary

Public Constructors
BeanValidationPostProcessor()
Public Methods
void afterPropertiesSet()
Invoked by a BeanFactory after it has set all bean properties supplied (and satisfied BeanFactoryAware and ApplicationContextAware).
Object postProcessAfterInitialization(Object bean, String beanName)
Apply this BeanPostProcessor to the given new bean instance after any bean initialization callbacks (like InitializingBean's afterPropertiesSet or a custom init-method).
Object postProcessBeforeInitialization(Object bean, String beanName)
Apply this BeanPostProcessor to the given new bean instance before any bean initialization callbacks (like InitializingBean's afterPropertiesSet or a custom init-method).
void setAfterInitialization(boolean afterInitialization)
Choose whether to perform validation after bean initialization (i.e.
void setValidator(Validator validator)
Set the JSR-303 Validator to delegate to for validating beans.
void setValidatorFactory(ValidatorFactory validatorFactory)
Set the JSR-303 ValidatorFactory to delegate to for validating beans, using its default Validator.

Public Methods

public void afterPropertiesSet ()

Invoked by a BeanFactory after it has set all bean properties supplied (and satisfied BeanFactoryAware and ApplicationContextAware).

This method allows the bean instance to perform initialization only possible when all bean properties have been set and to throw an exception in the event of misconfiguration.

public Object postProcessAfterInitialization (Object bean, String beanName)

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 postProcessBeforeInstantiation(Class, String) method, in contrast to all other BeanPostProcessor callbacks.

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

public Object postProcessBeforeInitialization (Object bean, String beanName)

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.

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

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.

public void setValidator (Validator validator)

Set the JSR-303 Validator to delegate to for validating beans.

Default is the default ValidatorFactory's default Validator.

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.

Parameters
bean the bean instance to validate
