Can'；t为标签构建java对象：yaml.org，2002:

当我试图从数据文件创建对象时，当存在

assest

类时，我得到以下异常。我试过用dum；它能够转储数据，但当我尝试读取相同的数据时，出现以下异常：

 [ConstructorException: null; Can't construct a java object for tag:yaml.org,2002:model.Asset; exception=Class not found: model.Asset]

文件读取器：

package utill;

import org.yaml.snakeyaml.Yaml;
import java.io.File;
import java.io.FileInputStream;
import java.io.*;
import java.io.InputStream;
import java.util.*;
import model.*;
import java.util.LinkedHashMap;
import org.yaml.snakeyaml.constructor.Constructor;


public class FileReaderUtill  {

    public static List getAssest(String fileName){
        LinkedHashMap<String,Asset> assest=null;
        List<Asset> data= new ArrayList<Asset>();
        try{
            InputStream input = new FileInputStream(new 
            File("conf/datafile.yaml"));
            Yaml yaml = new Yaml();

            data=(List<Asset>)yaml.load(input);

            //System.out.println(assest.get("Asset0"));
        }catch(IOException e){
             e.printStackTrace();
        }
    return data;
    }
}

java

package model;


public class Asset  {
    public Asset(){
    }
    public Asset(String id,String cid,String name,String internalName,String enable ){
        this.id=id;
        this.name=name;
        this.internalName=internalName;
        this.enable=enable;
    }

    public String id;
    public String cid;
    public String name;
    public String internalName;
    public String enable;   

}

请帮助我解决这个问题。

您的资产类是否实际位于名为Assest.java的文件中？

package model;


public class Asset  {
    public Asset(){
    }
    public Asset(String id,String cid,String name,String internalName,String enable ){
        this.id=id;
        this.name=name;
        this.internalName=internalName;
        this.enable=enable;
    }

    public String id;
    public String cid;
    public String name;
    public String internalName;
    public String enable;   

}
