我正在尝试将 Apache CXF 与 Spring 集成以创建 RESTful 网络服务。但是在部署应用程序时，我遇到了以下异常。

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]

这是我的 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://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 是

我不确定我缺少什么 jar 或配置。

我添加了 cxf-rt-frontend-jaxrs jar，但仍然出现相同的异常

最佳答案

据此guide ，您可能想尝试在您的 pom 中添加以下依赖项。

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