Class AbstractMethodValidationInterceptor

java.lang.Object

io.quarkus.hibernate.validator.runtime.interceptor.AbstractMethodValidationInterceptor

All Implemented Interfaces:

Serializable

Direct Known Subclasses:

JaxrsEndPointValidationInterceptor, MethodValidationInterceptor, ResteasyReactiveEndPointValidationInterceptor

public abstract class AbstractMethodValidationInterceptor
extends Object
implements Serializable

NOTE: this is a copy of the interceptor present in hibernate-validator-cdi. For now, I prefer not depending on this artifact but this might change in the future.

An interceptor which performs a validation of the Bean Validation constraints specified at the parameters and/or return values of intercepted methods using the method validation functionality provided by Hibernate Validator.

Field Detail

validatorInstance

@Inject
javax.enterprise.inject.Instance<javax.validation.Validator> validatorInstance

The validator to be used for method validation.

Although the concrete validator is not necessarily serializable (and HV's implementation indeed isn't) it is still alright to have it as non-transient field here. Upon passivation not the validator itself will be serialized, but the proxy injected here, which in turn is serializable.

Instance is used to make the resolution dynamic and working at runtime, this delays Validator injection enough to enable it to work for beans that observe @Initialized(ApplicationScoped.class) event.

Method Detail

validateMethodInvocation

protected Object validateMethodInvocation(javax.interceptor.InvocationContext ctx)
                                   throws Exception

Validates the Bean Validation constraints specified at the parameters and/or return value of the intercepted method.

Parameters:

ctx - The context of the intercepted method invocation.

Returns:

The result of the method invocation.

Throws:

Exception - Any exception caused by the intercepted method invocation. A ConstraintViolationException in case at least one constraint violation occurred either during parameter or return value validation.

validateConstructorInvocation

protected void validateConstructorInvocation(javax.interceptor.InvocationContext ctx)
                                      throws Exception

Validates the Bean Validation constraints specified at the parameters and/or return value of the intercepted constructor.

Parameters:

ctx - The context of the intercepted constructor invocation.

Throws:

Exception - Any exception caused by the intercepted constructor invocation. A ConstraintViolationException in case at least one constraint violation occurred either during parameter or return value validation.
