Subject [jira] [Commented] (BEANUTILS-384) ConvertUtilsBean unable to process javassist classes
Date Tue, 22 Mar 2011 11:13:06 GMT

    [ https://issues.apache.org/jira/browse/BEANUTILS-384?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13009616#comment-13009616

Niall Pemberton commented on BEANUTILS-384:
-------------------------------------------

Switching from a straight Map.get() to looping over all entries to find a converter may have
a negative impact where BeanUtils is heavily used.

You can override the ConvertUtilsBean's lookup(Class, Class) method to implement this behaviour
yourself and then register your custom ConvertUtilsBean using:

{code}
BeanUtilsBean.setInstance(new BeanUtilsBean(new CustomConvertUtilsBean()));
{code}

> The ConvertUtils uses ConvertUtils.register(userConverter , User.class) to register a
converter.
> And use converters.get(clazz) in Converter.lookup() to find proper converter.
> It won't work for javassist modified object . 
> for example , the User.class runtime becomes User_$$_javassist_0.class , and Converter
is unable to find the corresponding converter.
> So , I suggest the future version can loop the converters map , and use User.class.isAssignableFrom(clazz_in_map)
to find corresponding converter.
