How to copy properties from one Java bean to another?

Question

I have a simple Java POJO that I would copy properties to another instance of same POJO class.

I know I can do that with BeanUtils.copyProperties() but I would like

Answer 1

I ran into some problems with Introspector.getBeanInfo not returning all the properties, so I ended up implementing a field copy instead of property copy.

public static  void copyFields(T target, T source) throws Exception{
    Class clazz = source.getClass();

    for (Field field : clazz.getFields()) {
        Object value = field.get(source);
        field.set(target, value);
    }
}
