Registering a custom WebBindingInitializer

[aurelije]

Hello,

I am having a problem with registering a custom WebBindingInitializer. I need it because I want @DateTimeFormat on JodaTime DateTime fields in command object to work (shouldn't it work automatically? but it doesn't). So I need to set conversion service. I managed to set it in @InitBinder annotated method in Controller and it works as expected, but I would like to have global setting so I made WebBindingInitializer to do the same logic as @InitBinder:

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.core.convert.ConversionService;
import org.springframework.web.bind.WebDataBinder;
import org.springframework.web.bind.support.WebBindingInitializer;
import org.springframework.web.context.request.WebRequest;

public class CommonWebBindingInitializer implements WebBindingInitializer {

    @Autowired
    private ConversionService conversionService;

    @Override
    public final void initBinder(final WebDataBinder p_binder, final WebRequest p_request) {
        p_binder.setConversionService(conversionService);
    }
}

My spring configuration is like in documentation. I read that using <mvc:annotation-driven> can make a problem but I am not using that tag. I tried to debug and found that initBinder method of CommonWebBindingInitializer is not called at all. This is my configuration:

<bean id="conversionService"
      class="org.springframework.format.support.FormattingConversionServiceFactoryBean"/>

<bean id="localeChangeInterceptor" class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor">
   <property name="paramName" value="language" />
</bean>

<bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping">
   <property name="alwaysUseFullPath" value="true" />
   <property name="interceptors">
      <list>
            <ref bean="localeChangeInterceptor" />
            <bean class="bla.truc.buc.common.util.web.interceptor.ViewNameResolverInterceptor" />
      </list>
   </property>
   <property name="order" value="1" />
</bean>

<bean class="org.springframework.webflow.mvc.servlet.FlowHandlerMapping">
   <property name="flowRegistry" ref="flowRegistry" />
   <property name="order" value="2" />
</bean>

<bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter">
</bean>

<bean class="org.springframework.webflow.mvc.servlet.FlowHandlerAdapter">
   <property name="flowExecutor" ref="flowExecutor" />
</bean>

<mvc:default-servlet-handler />

<bean id="fileDownloadView" class="bla.truc.buc.retail.web.view.FileDownloadView" />

<context:component-scan base-package="bla.truc.buc.retail.web.validator, bla.truc.buc.retail.web.property.editor"/>

<bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping">
   <property name="alwaysUseFullPath" value="true" />
   <property name="interceptors">
      <list>
            <ref bean="localeChangeInterceptor" />
      </list>
   </property>
</bean>

<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
   <property name="maxUploadSize" value="5000000" />
</bean>

<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
   <property name="cacheSeconds" value="0" />
   <property name="webBindingInitializer">
      <bean class="bla.truc.buc.retail.web.util.CommonWebBindingInitializer" />
   </property>
</bean

Thank you!

I'm actually having the exact same problem, were you able to figure this out? I also tried to debug this and I put in a constructor in the class that implements WebBindingInitializer and found that the constructor is being called, but never the initBinder method which is overwritten.

I managed to resolve problem using <mvc:annotation-driven /> meta tag. I could not do it manually.

So now I don't need bla.truc.buc.retail.web.util.CommonWebBindingIniti alizer class, everything runs OK
