java - apache cxf rest 服务中的 Spring 异常

Question

我正在学习如何使用 apache cxf 构建休息服务，并且我遵循了一个教程。但是当我运行代码时出现以下异常

SEVERE: Context initialization failed org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 15 in XML document from class path resource [com/example/rest/cxf.xml] is invalid; nested exception is org.xml.sax.SAXParseException;

我的cxf.xml文件是这样的

    <?xml version="1.0" encoding="UTF-8"?>

<beans xmlns:jaxrs="http://cxf.apache.org/jaxrs"

    </jaxrs:server> <bean class="com.example.rest.OrderInfoImpl" id="order">
    </bean>

    </import></import></import></beans>

请帮我解决这个问题。

您在导入类中声明了 jaxrs bean，这是错误的，这是更新的 beans.xml 文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns:jaxrs="http://cxf.apache.org/jaxrs"
