我在启动我的应用程序时遇到问题。

当我启动mvn jetty:run时，出现以下异常：

2013-08-21 12:14:59.977:WARN:oejw.WebAppContext:Failed startup of context

我的 DChars 课程：

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 Spring 版本是：3.2.3.RELEASE

据我了解，at.itn.shadowrun.domain.DChars找不到该类，但我不明白为什么。它肯定在正确的包装中！

任何帮助将非常感激！谢谢你！

编辑：我更改了@XStreamAlias("DChars")（调用了 db 类D_CHARS，但在 applicationContext 中我将其称为DChars。但不幸的是它没有帮助

edit2：因为我不知道问题出在哪里，并且想确保我没有忽略applicationContext.xml中的一个严重错误，所以我将在此处添加完整文件：

我仍然没有得到问题，因为文件DChars肯定在at.itn.shadowrun.domain包中。如果有人有任何想法帮助将不胜感激！

更改 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>

并确保在 DChars 类的应用程序上下文中有相应的 bean。
