fastjson反序列化成泛型对象失败，不支持吗？

import com.alibaba.fastjson.JSON;
import com.alibaba.fastjson.TypeReference;

public class SS
{
    public static void main(String[] args)
    {
        SS s = new SS();
        
        Book book = s.StrToObject();
        
        System.out.println(book.toString());
    }
    
    public <T> T StrToObject()
    {
        Book book = new Book();
        
        book.setName("java");
        book.setAuthor("Tom");
        book.setAuthor("100");
        
        String str = JSON.toJSONString(book);
        
        T t = JSON.parseObject(str, new TypeReference<T>()
        {
        });
        
        Book newbook = JSON.parseObject(str, Book.class);
        
        System.out.println(newbook.toString()); // 这样是可以的
        
        return t;
    }
}

class Book
{
    private String name;
    
    private String author;
    
    private int price;
    
    public String getName()
    {
        return name;
    }
    
    public void setName(String name)
    {
        this.name = name;
    }
    
    public String getAuthor()
    {
        return author;
    }
    
    public void setAuthor(String author)
    {
        this.author = author;
    }
    
    public int getPrice()
    {
        return price;
    }
    
    public void setPrice(int price)
    {
        this.price = price;
    }
    
    @Override
    public String toString()
    {
        return "Book [name=" + name + ", author=" + author + ", price=" + price + "]";
    }
}

代码编译不会报错，运行时报

Book [name=java, author=100, price=0]
Exception in thread "main" java.lang.ClassCastException: com.alibaba.fastjson.JSONObject cannot be cast to Book
	at SS.main(SS.java:10)

很明显类型转换失败，问题时方法是泛型方法，编译也过了。

已经自行解决，原来需要打开autotype，但是据说有安全漏洞。
