I have 5 controllers and i would like to register an InitBinder to all of them.
I know i can add this code to each of them.
@InitBinder
public void initBinder(WebDataBinder binder)
{
binder.registerCustomEditor(StringWrapper.class, new StringWrapperEditor());
}
But i would like to define it only once (even create a bean of StringWrapperEditor and use it instead of creating new every time.)
I searched SO and some other places but didn't find any answear. Is it even possible?
Im using spring 3.1.1 with java 1.6.
Implement a PropertyEditorRegistrar which registers all your custom PropertyEditors. Then in your configuration add a ConfigurableWebBindingInitializer which you hookup with the created PropertyEditorRegistrar and hook it to your HandlerAdapter.
public class MyPropertyEditorRegistrar implements PropertyEditorRegistrar {
public void registerCustomEditors(PropertyEditorRegistry registry) {
registry.registerCustomEditor(StringWrapper.class, new StringWrapperEditor());
}
}
If you have a <mvc:annotation-driven /> tag in your configuration, the problem is that with this tag you cannot add the WebBindingInitializer to the adapter next to that there is already a ConfigurableWebBindingInitializer added to the pre-configured HandlerAdapter. You can use a BeanPostProcessor to proces and configure the bean.
public class MyPostProcessor implements BeanPostProcessor {
public Object postProcessBeforeInitialization(Object bean, String name) throws BeansException {
if (bean instanceof RequestMappingHandlerAdapter) {
WebBindingInitializer wbi = ((RequestMappingHandlerAdapter) bean).getWebBindingInitializer();
if (wbi == null) {
wbi = new ConfigurableWebBindingInitializer();
((RequestMappingHandlerAdapter) bean).setWebBindingInitializer(wbi);
}
if (wbi instanceof ConfigurableWebBindingInitializer) {
((ConfigurableWebBindingInitializer) wbi).setPropertyEditorRegistrar(new MyPropertyEditorRegistrar());
}
}
}
}
Requires a bit of work but it is doable. You could also implement your own WebBindingInitializer.
If you don't have the tag you can simply manually configure a RequestMappingHandlerAdapter and wire everything together.
