//设置属性
Map<String, Object> map = new HashMap<>();
BeanUtils.setProperty(map, "name", "张三");
//读取属性
String name = BeanUtils.getProperty(map, "name");
System.out.println("name=" + name);复制对象的所有属性
Student s1 = new Student();
s1.setAge(1);
s1.setName("张三");
Student s2 = new Student();
BeanUtils.copyProperties(s2, s1);
System.out.println(s2.getName() + ":" + s2.getAge());
//输出：张三:1克隆对象（浅克隆）
Student s1 = new Student();
s1.setAge(1);
s1.setName("张三");
Student s2 = (Student) BeanUtils.cloneBean(s1);
System.out.println(s2.getName() + ":" + s2.getAge());
//输出：张三:1将map数据拷贝到对象中
Map<String, Object> map = new HashMap<>();
map.put("name", "张三");
