Spring 使用resttemplate从xml解组对象时出错

我正在使用spring的resttemplate调用rest api获取错误以解组xml对象我的代码是：-

String  uri = "http://devd.webservice.com/devpl/api/1.0/credential?apiKey=" + apiKey + "&signature=" + signature + "&timeStamp=" + timeStamp;
        HttpHeaders requestHeaders = new HttpHeaders();
        requestHeaders.set("accountName", accountName);
        requestHeaders.set("containerName", containerName);
        requestHeaders.set("folderPath", folderPath);
        requestHeaders.set("Content-Type","application/xml");
        requestHeaders.set("Accept","application/xml");
        RestTemplate template = getRestTemplate();
        HttpEntity<String> requestEntity = new HttpEntity<String>(requestHeaders);
        Credential result =(Credential)template.postForObject(uri,requestEntity,Credential.class);

我的spring配置文件：-

<bean id="restTemplate" class="org.springframework.web.client.RestTemplate">
    <property name="messageConverters">
    <list>
      <bean id="messageConverter" class="org.springframework.http.converter.xml.MarshallingHttpMessageConverter">
        <property name="marshaller" ref="xstreamMarshaller" />
        <property name="unmarshaller" ref="xstreamMarshaller" />
      </bean>
    </list>
    </property>
  </bean>

 <bean id="xstreamMarshaller" class="org.springframework.oxm.xstream.XStreamMarshaller">
  <property name="aliases">
    <props>
      <prop key="credential">com.simplidrivechn.netmagicsolutions.bean.Credential</prop>
    </props>
  </property>
 </bean>
</beans>

请帮助我解决此错误

查看您的异常，您的spring上下文中似乎没有正确设置

XStreamMarshaller的

别名。您必须确保键是“别名”，即案例中的根元素。“凭证”是您试图反序列化的xml响应的根元素吗？请注意，别名区分大小写。下面的代码适合我。注意

别名.put（“person”，person.class）我的xml响应具有根元素“person”。如果我把这个键改成“Person”，比如
aliases.put（“Person”，Person.class）我和你一样也有例外

XStreamMarshaller marshaller = new XStreamMarshaller();
Map<String, Class> aliases = new HashMap<String, Class>();
aliases.put("person", Person.class);
marshaller.setAliases(aliases);
MarshallingHttpMessageConverter converter = new MarshallingHttpMessageConverter(
                marshaller, marshaller);
List<HttpMessageConverter<?>> converters = new ArrayList<HttpMessageConverter<?>>();
converters.add(converter);
template.setMessageConverters(converters);
HttpEntity request = new HttpEntity(null, headers);
ResponseEntity<Person> response = template.exchange(url,
                HttpMethod.GET, request, Person.class);

XStreamMarshaller marshaller=new XStreamMarshaller（）；
映射别名=新HashMap（）；
别名.put（“person”，person.class）；
marshaller.setalias（别名）；
MarshallingHttpMessageConverter=新的MarshallingHttpMessageConverter(
马歇尔勒，马歇尔勒）；
列表>（）；
转换器。添加（转换器）；
模板.setMessageConverters（转换器）；
HttpEntity请求=新的HttpEntity（空，标题）；
ResponseEntity response=template.exchange（url，
HttpMethod.GET、请求、Person.class）；
另一种定义别名的方法是自动扫描

<bean id="xstreamMarshaller" class="org.springframework.oxm.xstream.XStreamMarshaller">
    <property name="autodetectAnnotations" value="true"/>
    <property name="annotatedClasses">
        <array>
            <value>com.simplidrivechn.netmagicsolutions.bean.Credential</value>
        </array>
    </property>
</bean>


com.simplidrivechn.netmagicsolutions.bean.Credential

XStreamMarshaller marshaller = new XStreamMarshaller();
Map<String, Class> aliases = new HashMap<String, Class>();
aliases.put("person", Person.class);
marshaller.setAliases(aliases);
MarshallingHttpMessageConverter converter = new MarshallingHttpMessageConverter(
                marshaller, marshaller);
List<HttpMessageConverter<?>> converters = new ArrayList<HttpMessageConverter<?>>();
converters.add(converter);
template.setMessageConverters(converters);
HttpEntity request = new HttpEntity(null, headers);
ResponseEntity<Person> response = template.exchange(url,
                HttpMethod.GET, request, Person.class);

<bean id="xstreamMarshaller" class="org.springframework.oxm.xstream.XStreamMarshaller">
    <property name="autodetectAnnotations" value="true"/>
    <property name="annotatedClasses">
        <array>
            <value>com.simplidrivechn.netmagicsolutions.bean.Credential</value>
        </array>
    </property>
