validation - How to configure custom message interpolation with Hibernate? -

-

i write custom message interpolation. want jpa use custom message interpolation. here http://docs.jboss.org/hibernate/validator/4.2/reference/en-us/html/validator-bootstrapping.html#section-message-interpolator found following description:

configuration<?> configuration = validation.bydefaultprovider().configure(); validatorfactory factory = configuration     .messageinterpolator(new valueformattermessageinterpolator(configuration.getdefaultmessageinterpolator()))     .buildvalidatorfactory();  validator validator = factory.getvalidator();

but should write such code? in web.xml in init-servlet? can provide such code in persistance.xml?

p.s. copy&paste code. in case line

valueformattermessageinterpolator(configuration.getdefaultmessageinterpolator()))

will change on this

custommessageinterpolator(configuration.getdefaultmessageinterpolator()))

see how dynamically resolve message parameters hibernate validator?

the jsr-303 bean validation framework provides possibility configure validatation framework via xml.

e.g. meta-inf/validation.xml

see chapter

4.4.6. xml configuration: meta-inf/validation.xml

of spec details: http://download.oracle.com/otndocs/jcp/bean_validation-1.0-fr-oth-jspec/

4.4.6. xml configuration: meta-inf/validation.xml

<?xml version="1.0" encoding="utf-8"?> <validation-config     xmlns="http://jboss.org/xml/ns/javax/validation/configuration"     xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"     xsi:schemalocation="http://jboss.org/xml/ns/javax/validation/configuration validation-configuration-1.0.xsd">     <default-provider>com.acme.acmeprovider</default-provider>     <message-interpolator>com.acme.acmeawaremessageinterpolator</message-interpolator>     <constraint-mapping>meta-inf/validation/order-constraints.xml</constraint-mapping>     <constraint-mapping>meta-inf/validation/catalog-constraints.xml</constraint-mapping>     <constraint-mapping>meta-inf/validation/customer-constraints.xml</constraint-mapping>     <property name="com.acme.validation.logging">warn</property>     <property name="com.acme.validation.safetychecking">failonerror</property> </validation-config>

package xml file persistence jar (meta-inf/validation.xml) , should work.

depending on deployment packaging (e.g. ear) might necessary put in shared lib in ear's lib folder.

the hibernate documentation says:

the key enable xml configuration hibernate validator file validation.xml. if file exists in classpath configuration applied when validationfactory gets created. example 4.1, “validation-configuration-1.0.xsd” shows model view of xsd valiation.xml has adhere to.
