public class BeanCopyTest {

    public static void main(String[] args){
        Student student = null;
        objectCopy(student);

        System.out.print(autoTenderSetDTO);
    }

    public static void objectCopy(Student student){
        student = new Student();
        student.setName("张三");
    }
}
