The Validation Validator component performs bean validation of the message body using the Java Bean Validation API (JSR 303). Camel uses the reference implementation, which is Hibernate Validator.

deployment
To use
The bean-validator when deployed in an OSGi environment requires a little help to accommodate the resource loading specified in JSR303, this was fixed in Servicemix-Specs 1.6-SNAPSHOT.
The other way to load Hibernate Validator in the OSGi environment is to use dedicated ValidationProviderResolver implementation, just as org.apache.camel.component.bean.validator.HibernateValidationProviderResolver. The snippet below demonstrates this approach. Keep in mind that you can use HibernateValidationProviderResolver starting from the Camel 2.13.0.
| Code Block |

from("direct:test").
to("bean-validator://ValidationProviderResolverTest?validationProviderResolver=#myValidationProviderResolver");
...
<bean id="myValidationProviderResolver" class="org.apache.camel.component.bean.validator.HibernateValidationProviderResolver"/> |
If no custom ValidationProviderResolver is defined and the validator component has been deployed into the OSGi environment, the HibernateValidationProviderResolver will be automatically used.
Example
Assumed we have a java bean with the following annotations
