仅将字符串属性从一个对象复制到另一个对象

I was working with dozer and I had a special scenario which I think dozer doesn't support. Suppose I have a class with different type of properties like String,Ingeger and other primitive types. Now I want to copy only string property from this class to another. Here s a example code :(Its very brief, but it will give proper understanding of problem.)

我正在使用推土机,我有一个特殊的场景,我认为推土机不支持。假设我有一个具有不同类型属性的类,如String,Ingeger和其他基本类型。现在我想只将此类的字符串属性复制到另一个类。这是一个示例代码:(非常简短,但它会正确理解问题。)

Class Source{
private int a;
private boolean b;
private String s1;
//more properties with primitive type.

}
Class Destination{
//    same structure
}

Now I want somethink like,

现在我想要一些想法,

DozerBeanMapper mapper = new DozerBeanMapper();
//    initialize Object of source
//   initialize Object of destination
mapper.map(source,destination);

Is it possible with any dozer ? I am familiar with dozer. But Oper to other APIs like apache beanutil or ModelMapper. Feel free to answer in any of this technology.

是否可以使用任何推土机?推土机我很熟悉。但是对其他API如Oache beanutil或ModelMapper。随意回答任何这项技术。

Use populate() and setProperty() of Apache Commons BeanUtils.

使用Apache Commons BeanUtils的populate()和setProperty()。

First populate() an empty bean, than, you can apply an if condition as:

首先populate()一个空bean,你可以将if条件应用为:

if (urBean.getAParameter() instanceof String){
    setProperty(newBeanObject, "propertyName", urBean.getParameter());
}
