How to check if bean property exist win BeanUtils or similar?

Question

Is there ready made routine to check if bean has getter for specific property name given by string?

Answer 1

You could do this, from BeanUtils:

static boolean propertyExists (Object bean, String property) {
    return PropertyUtils.isReadable(bean, property) && 
           PropertyUtils.isWriteable(bean, property); 
}

As far as I know there isn't a one-liner that encapsulates both of those, since readability / writeability are independent.

If you're only interested in the getter, PropertyUtils.isReadable() alone will work.
