無法找到XML模式命名空間的Spring NamespaceHandler [http://cxf.apache.org/jaxrs]

Question

我正在嘗試將Apache CXF與Spring集成以創建REST風格的Web服務。但在部署應用程序時，我收到以下例外情況。

SEVERE: Context initialization failed 
org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Unable to locate Spring NamespaceHandler for XML schema namespace [http://cxf.apache.org/jaxrs] 
Offending resource: ServletContext resource [/WEB-INF/beans.xml] 

這是我的beans.xml

<beans xmlns="http://www.springframework.org/schema/beans" 
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
     xmlns:jaxrs="http://cxf.apache.org/jaxrs" 
     xsi:schemaLocation=" 
     http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.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-soap.xml" /> 
    <import resource="classpath:META-INF/cxf/cxf-servlet.xml" /> 
    <jaxrs:server id="empservice" address="/"> 
     <jaxrs:serviceBeans> 
      <ref bean="empservice"/> 
     </jaxrs:serviceBeans> 
    </jaxrs:server> 

</beans> 

，我的pom.xml的是

我不知道我錯過了什麼罐子或配置。

我加入了CXF-RT-前端-JAXRS罐子，但仍然得到同樣的異常

按本guide，你可能要嘗試添加在你的POM以下依賴。

<dependency> 
    <groupId>org.apache.cxf</groupId> 
    <artifactId>cxf-rt-frontend-jaxrs</artifactId> 
    <version>${cxf.version}</version> 
</dependency>
