彈出錯誤創建bean xStreamMarshaller

我在啓動我的應用程序時遇到了問題。彈出錯誤創建bean xStreamMarshaller

當我開始命令mvn碼頭：運行，我得到以下例外：

我DChars類：

package at.itn.shadowrun.domain; 

@Entity 
@Table(name = "D_CHARS") 
@XStreamAlias("DChars") 
public class DChars implements DomainObject { 

    @Id 
    @GeneratedValue(strategy = GenerationType.AUTO) 
    private Long    id; 
// etc..

我的春天的版本是：3.2.3.RELEASE

從我的理解中找不到類at.itn.shadowrun.domain.DChars，但我不明白爲什麼。這絕對是正確的包裝！

任何幫助將不勝感激！謝謝！

編輯：我改變了@XStreamAlias("DChars")（DB類被稱爲D_CHARS，但在ApplicationContext中我稱其爲DChars但遺憾的是它並沒有幫助

我還是不明白這個問題，因爲文件DChars是肯定一世ñat.itn.shadowrun.domain包。如果有人有任何想法的幫助將不勝感激！

變化xStreamMarshaller如下：

<bean id="xstreamMarshaller" class="org.springframework.oxm.xstream.XStreamMarshaller"> 
    <property name="aliases"> 
     <props> 
      <prop key="D_CHARS">at.itn.shadowrun.domain.DChars </prop> 
     </props> 
    </property> 
    </bean>

，並確保你已經在DChars類應用的上下文相關的bean。

我試過了，但不幸的是問題似乎是一樣的： 'Property'aliases'throw exception;嵌套異常是java.lang.ClassNotFoundException：at.itn.shadowrun.domain.DChars' – Markus

你確切地說，「確保你在應用上下文中有相應的bean爲DChars類。」？我已經把DChars類放在'at.itn.shadowrun.domain'包中，並像你在示例代碼中那樣設置了prop鍵（我也嘗試過'key =「DChars」''因爲我重命名了'@ XStreamAlias'在DChars類中 – Markus

嘗試向xstreamMarshaller bean添加。在我的情況下，我在appcontext中爲Domain對象添加了bean。例如，在您的情況下：在appContext.xml中。 –
