import com.sl.sys.entity.Department;
import com.sl.sys.entity.Employee;
public class TestBeanUtils {
public static void main(String[] args) throws Exception {
Department dept = new Department();
dept.setId(1);
dept.setName("IT");
Employee emp = new Employee();
emp.setId(1);
emp.setDept(dept);
emp.setName("Mr Wang");
Employee emp2 = new Employee();
BeanUtils.copyProperties(emp2, emp);
dept.setName("Sale");
System.out.println(emp2);//此时emp2的dept名称字段name为Sale
}
}
由此可看拷贝的是属性若是为对象，则拷贝的为地址
