测试示例：

public void testSerialize(){
        Person person = new Person();
        person.setName("LULU");
        person.setSex("bitch");
        person.setAddress("北京海淀");
        person.setAge(20);
        person.setTel("1231312");
        person.setEducation("小学");
        String str=serializeObject(person);
        Person newP= (Person) deSerializeObject(str);
        if(newP!=null){
            String s=newP.toString();
        }
    User user=new User("192.168.0.30",8080);
        String userStr=serializeObject(user);
        User deUser= (User) deSerializeObject(userStr);
        int p=deUser.query_port;
        List<User> users=new ArrayList<>();//序列化集合，只需要集合类的数据可以被序列化就行，序列化的方法跟其他的类序列化的方法一样
        users.add(user);
        String l=serializeObject(users);
        List<User> newL= (List<User>) deSerializeObject(l);
        newL.toString();
    }
