我正在尝试按照此示例使用 RestTemplate 解析 RESTFull 调用的结果http://thekspace.com/home/component/content/article/57-restful-clients-in-spring-3.html http://thekspace.com/home/component/content/article/57-restful-clients-in-spring-3.html
XML 响应类似于:
<brands>
<brand>
<nodeRef>1111111</nodeRef>
<name>Test</name>
</brand>
</brands>
首先,我像这样配置了 application-context.xml:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd">
<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="brand">com.kipcast.dataModel.drugs.bean.BrandViewList</prop>
</props>
</property>
</bean>
</beans>
com.kipcast.dataModel.drugs.bean.BrandViewList 类是一个定义了 @XStreamAlias("brand") 的 bean。
这是我如何进行其余的调用:
ApplicationContext applicationContext = new ClassPathXmlApplicationContext("application-context.xml", WebscriptCaller.class);
RestTemplate restTemplate = applicationContext.getBean("restTemplate", RestTemplate.class);
String url = "http://localhost:8081/alfresco/service/search/brand.xml?q={keyword}&alf_ticket={ticket}";
List<BrandViewList> results = (List<BrandViewList>) restTemplate.getForObject(url, List.class, params);
WebscriptCaller.class 是我执行这些指令的类。
当我尝试执行该操作时, getForObject() 失败并且出现该异常:
XStream unmarshalling exception; nested exception is com.thoughtworks.xstream.mapper.CannotResolveClassException: brands
我的问题是,我该如何解决这个问题?为什么我会收到这种异常?我怎样才能告诉他跳过根标签?

修复了一些问题,特别是:
List<Brand> brandViewList = (List<Brand>) restTemplate.getForObject(url, Brand.class, params);
但现在的结果是:
org.springframework.http.converter.HttpMessageNotReadableException: Could not read [class com.kipcast.dataModel.drugs.bean.Brand]; nested exception is org.springframework.oxm.UnmarshallingFailureException: XStream unmarshalling exception; nested exception is com.thoughtworks.xstream.converters.ConversionException: nodeRef : nodeRef
