apache cxf rest服务中的Spring异常

Question

我正在学习如何使用apache cxf构建rest服务，并学习了一个教程。但当我运行代码时，我遇到了以下异常

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" 
xmlns:util="http://www.springframework.org/schema/util" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xmlns="http://www.springframework.org/schema/beans" 
xsi:schemalocation=
           "http://www.springframework.org/schema/beans      
            http://www.springframework.org/schema/beans/spring-beans-4.2.xsd 
            http://www.springframework.org/schema/tx  
            http://www.springframework.org/schema/tx/spring-tx-4.2.xsd 
            http://www.springframework.org/schema/context  
            http://www.springframework.org/schema/context/spring-context-4.2.xsd
            http://cxf.apache.org/jaxrs 
            http://cxf.apache.org/schemas/jaxrs.xsd">   

<import resource="classpath:META-INF/cxf/cxf.xml">  
<import resource="classpath:META-INF/cxf/cxf-extension-jaxrs-binding.xml">  
<import resource="classpath:META-INF/cxf/cxf-servlet.xml">  
<jaxrs:server address="/" id="connectionService">  

 <jaxrs:servicebeans>             
  <ref bean="order">    </ref></jaxrs:servicebeans> 

    <jaxrs:extensionmappings>    
    <entry key="xml" value="application/xml">   
    </entry></jaxrs:extensionmappings>  
    </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import类中声明了jaxrs bean，这是错误的，下面是更新的beans.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns:jaxrs="http://cxf.apache.org/jaxrs" 
       xmlns:util="http://www.springframework.org/schema/util" 
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
       xmlns="http://www.springframework.org/schema/beans" 
       xsi:schemalocation=
           "http://www.springframework.org/schema/beans      
            http://www.springframework.org/schema/beans/spring-beans-4.2.xsd 
            http://www.springframework.org/schema/tx  
            http://www.springframework.org/schema/tx/spring-tx-4.2.xsd

    <jaxrs:server address="/" id="connectionService">

        </jaxrs:servicebeans> 
        <jaxrs:extensionmappings> 
            <entry key="xml" value="application/xml"></entry>
        </jaxrs:extensionmappings>  
    </jaxrs:server> 

    <bean class="com.example.rest.OrderInfoImpl" id="order" />
</beans>
