[beanutils]how can I use BeanUtils.populate to set value to my property with diff-argument type between setter and getter?

[Yang Diddy <io...@gmail.com>]

Please help:
if property of my class's setter and setter method arguments type doesn’t match, how can i populate bean object?

public class Foo extends SomeClass{
private int id;

@Override
public Object getId() {
  return id;
}

public void setId(int id) {
   this.id = id;
}
}

// testing
Foo foot = new Foo();
Map<String,Object> values = new HashMap<String,Object>();
values.put(“id”,”1000”);
BeanUtils.populate(foo, values);
logger.debug(foo);

Per default, BeanUtils only supports classes complying to the Java Beans
specification. This is obviously not the case for your class.

>From version 1.9.x onwards, BeanUtils allows extending the introspection
facilities so that non-conform properties could be detected, too. This
is described in the user guide [1].

I am not sure whether this is an option for you because it requires some
effort to implement a custom BeanIntrospector just to add support for
these properties with incompatible argument types. But AFAIK, this is
the only way to make BeanUtils recognize them.
