我使用非常简单的代码返回XML

RestTemplate restTemplate = new RestTemplate();

Source oResponse = restTemplate.postForObject(url, entity, Source.class,
            vars);

XPathOperations xpathTemplate = new Jaxp13XPathTemplate();
String address = xpathTemplate.evaluateAsString("//status", oResponse);

但是，出现以下错误

java.lang.NoSuchMethodError: org.springframework.util.ClassUtils.forName(Ljava/lang/String;)Ljava/lang/Class;
at org.springframework.xml.JaxpVersion.<clinit>(JaxpVersion.java:51)
at org.springframework.xml.transform.TraxUtils.isStaxSource(TraxUtils.java:70)
at org.springframework.xml.xpath.Jaxp13XPathTemplate.evaluate(Jaxp13XPathTemplate.java:131)
at org.springframework.xml.xpath.Jaxp13XPathTemplate.evaluateAsString(Jaxp13XPathTemplate.java:91)

请帮忙。谢谢
