## org.apache.commons.beanutils
Class BeanUtilsBean2

    java.lang.Object
      org.apache.commons.beanutils.BeanUtilsBean
          org.apache.commons.beanutils.BeanUtilsBean2

    public class BeanUtilsBean2

extends BeanUtilsBean

`BeanUtilsBean` implementation that creates a `ConvertUtilsBean2` and delegates conversion to `ConvertUtilsBean.convert(Object, Class)`.

To configure this implementation for the current context ClassLoader invoke `BeanUtilsBean.setInstance(new BeanUtilsBean2());`

BeanUtils 1.7.0 delegated all conversion to String to the converter registered for the `String.class`. One of the improvements in BeanUtils 1.8.0 was to upgrade the `Converter` implementations so that they could handle conversion to String for their type (e.g. IntegerConverter now handles conversion from an Integer to a String as well as String to Integer).

In order to take advantage of these improvements BeanUtils needs to change how it gets the appropriate `Converter`. This functionality has been implemented in the new `ConvertUtilsBean.lookup(Class, Class)` and `ConvertUtilsBean.convert(Object, Class)` methods. However changing `BeanUtilsBean` to use these methods could create compatibility issues for existing users. In order to avoid that, this new `BeanUtilsBean` implementation has been created (and the associated `ConvertUtilsBean2`).

Since:
  1.8.0
