spring mvc - org.hibernate.validator.constraints not picking reloaded messages -

i trying use spring's reloadableresourcebundlemessagesource localvalidatorfactorybean when update error message should reflect without requiring server restarted. using spring 4.1.4, hibernate-validator 4.3.2.final. below code details -

context.xml -

<mvc:annotation-driven validator="validator" /> <bean id="messagesource" class="org.springframework.context.support.reloadableresourcebundlemessagesource">        <property name="basenames">           <list>               <value>file:../conf/fileapplication</value> <!-- messages here override below properties file-->             <value>/web-inf/application</value>         </list>       </property>     <property name="cacheseconds" value="10"></property> <!-- check refresh every 10 seconds --> </bean> <bean name="validator"     class="org.springframework.validation.beanvalidation.localvalidatorfactorybean">     <property name="validationmessagesource">         <ref bean="messagesource"/>     </property> </bean> 

model -

import org.hibernate.validator.constraints.notblank; public class inputform {  @notblank ( message = "{required.string.blank}") string requiredstring; 

controller -

@requestmapping(value = "/check/string", method = requestmethod.post) public string checkstring(         @modelattribute("formmodel") @valid inputform  inputform ,         bindingresult result, model model, httpservletresponse response,         httpservletrequest request) {         if (result.haserrors()) {         model.addattribute("formmodel", inputform);         return "userinput";         }       // backend validation string         result.reject("string.not.valid",                 "string invalid");         model.addattribute("formmodel", inputform);         return "userinput"; } 

application.properties (in /web_inf/ folder)

required.string.blank=please enter required string. string.not.valid=please enter valid string. 

fileapplication.properties (in /conf/ folder. override above file)

required.string.blank=you did not enter required string. #does not reflect when change here string.not.valid=you did not enter valid string. #reflects when change here 

now problem facing is, when update "string.not.valid" in fileapplication.properties reflects @ runtime , see updated message. when update "required.string.blank" in fileapplication.properties not reflect @ runtime. note overriding part working fine both messages upon application start up. "reloading" part not working fine "required.string.blank".

this figured out based on research - need create our own messageinterpolator , add dependency validator instead of message source. because when add messagesource dependency, cached default validator , message reloads spring won't take effect in validator's cached instance of messagesource.

below details:

in context.xml, add custom messageinterpolator dependency localvalidatorfactorybean instead of messagesource:

<mvc:annotation-driven validator="validator" /> <bean id="messagesource" class="org.springframework.context.support.reloadableresourcebundlemessagesource">    <property name="basenames">       <list>           <value>file:../conf/fileapplication</value> <!-- messages here override below properties file-->         <value>/web-inf/application</value>     </list>   </property> <property name="cacheseconds" value="10"></property> <!-- check refresh every 10 seconds --> </bean>  <bean name="validator" class="org.springframework.validation.beanvalidation.localvalidatorfactorybean">     <property name="messageinterpolator">         <ref bean="messageinterpolator"/>     </property> </bean>  <bean name="messageinterpolator"     class="com.my.org.support.mycustomresourcebundlemessageinterpolator">     <constructor-arg ref="messagesource" /> </bean> 

create custom messageinterpolator extending hibernate's org.hibernate.validator.messageinterpolation.resourcebundlemessageinterpolator.

public class mycustomresourcebundlemessageinterpolatorextends     resourcebundlemessageinterpolator {     public mycustomresourcebundlemessageinterpolator(messagesource messagesource)     {     // passing false second argument      // in super() constructor avoids messages being cached.     super(new messagesourceresourcebundlelocator(messagesource), false);         } } 

model, controller , properties file can same in question.
