java.lang.ClassNotFoundException in Spring project

Каким-то образом, похоже, у меня есть класс, который нельзя увидеть весной. Я новичок в структуре, и я не вижу, где проблема. Это проблема из версии, которую я использовал в зависимостях, или это другая вещь? Это трассировки стека:java.lang.ClassNotFoundException in Spring project

класс, который вызывает проблему:

@Entity 
@Table(name="stock") 
public class Stock implements Serializable { 

private Integer stockId; 
private String stockCode; 
private String stockName; 
public Stock() { 
    // TODO Auto-generated constructor stub 
} 

@Id 
@GeneratedValue(strategy=GenerationType.AUTO) 
@Column(name="stock_id") 
public Integer getStockId() { 
    return stockId; 
} 
public void setStockId(Integer stockId) { 
    this.stockId = stockId; 
} 

@Column(name="stock_code") 
public String getStockCode() { 
    return stockCode; 
} 
public void setStockCode(String stockCode) { 
    this.stockCode = stockCode; 
} 

@Column(name="stock_name") 
public String getStockName() { 
    return stockName; 
} 
public void setStockName(String stockName) { 
    this.stockName = stockName; 
} 


}

есть все, что я должен добавить?

Попробуйте удалить '.java' в файле' hibernate.cfg.xml' (''). – Tunaki

Я попробовал. он не имеет никакого эффекта – dskfdskjgds

Выделить исключение для пружины сервлета java.lang.ClassNotFoundException: com.sss.model.Stock – dskfdskjgds

Вам не нужно использовать файл сопоставления спящего режима, если вы уже используете аннотации в Entity. Как и в одном из комментариев выше, вы смешиваете аннотации и конфигурацию xml.

, которая решила мою проблему. Спасибо – dskfdskjgds

Похоже, у вас есть опечатка в файле hibernate.cfg.xml.

<session-factory> 
    <mapping class="com.sss.model.Stock" /> 
</session-factory>

Нет необходимости заканчивать .java.

еще Выделяет исключение для сервлета весной java.lang.ClassNotFoundException: com.sss.model.Stock \t на org.apache.catalina.loader.WebappClassLoader.loadClass – dskfdskjgds

я попытался удалить .java end – dskfdskjgds

ваше исключение говорит: java.lang.ClassNotFoundException: com.sss.model.Stock.java. Что такое пакет вашего класса? – SWiggels
