Maven users will need to add the following dependency to their pom.xml for this component:

Code Block

	xml
	xml


<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-bean-validator</artifactId>
    <version>x.xy.x<z</version>
    <!-- use the same version as your Camel core version -->
</dependency>

URI format

Code Block
bean-validator:somethinglabel[?options]

or

Code Block
bean-validator://somethinglabel[?options]

Where something must be present to provide a valid url label is an arbitrary text value describing the endpoint.
You can append query options to the URI in the following format, ?option=value&option=value&...

...

Assumed we have a java bean with the following annotations

Code Block

title	Car.java


public class Car {

    @NotNull
    private String manufacturer;

    @NotNull
    @Size(min = 5, max = 14, groups = OptionalChecks.class)
    private String licensePlate;
    
    // getter and setter
}

...

Code Block

title	OptionalChecks.java


public interface OptionalChecks {
}

with the following Camel route, only the @NotNull constraints on the attributes manufacturer and licensePlate will be validated (Camel uses the default group javax.validation.groups.Default).

Code Block
from("direct:start") .to("bean-validator://x") .to("mock:end")

If you want to check the constraints from the group OptionalChecks, you have to define the route like this

Code Block
from("direct:start") .to("bean-validator://x?group=OptionalChecks") .to("mock:end")

...

Code Block

title	AllChecks.java


@GroupSequence({Default.class, OptionalChecks.class})
public interface AllChecks {
}

and then your route definition should looks like this

Code Block
from("direct:start") .to("bean-validator://x?group=AllChecks") .to("mock:end")

And if you have to provide your own message interpolator, traversable resolver and constraint validator factory, you have to write a route like this

Code Block


<bean id="myMessageInterpolator" class="my.ConstraintValidatorFactory" />
<bean id="myTraversableResolver" class="my.TraversableResolver" />
<bean id="myConstraintValidatorFactory" class="my.ConstraintValidatorFactory" />

from("direct:start")
.to("bean-validator://x?group=AllChecks&messageInterpolator=#myMessageInterpolator
&traversableResolver=#myTraversableResolver&constraintValidatorFactory=#myConstraintValidatorFactory")
.to("mock:end")

...
