您需要在API中注释您的API serviceBean，带有 javax.ws.rs 的注释，表示HTTP方法，如 GET ， PUT ， POST ， DELETE 等。这会将您的API暴露给您的JAX-RS服务器将需要在CXF配置XML中创建。这样的事情 -

You will need to annotate your APIs in the serviceBean with javax.ws.rs based annotations representing HTTP methods like GET, PUT, POST, DELETE, etc. This will expose your APIs to the JAX-RS server you will need to create in CXF configuration XML. Something like this -

<jaxrs:server id="base" address="/">
    <jaxrs:providers>
        <ref bean="provider1" />
        <ref bean="provider2" />            
    </jaxrs:providers>
    <jaxrs:serviceBeans>
        <ref bean="serviceBean" />
    </jaxrs:serviceBeans>
</jaxrs:server>

此配置文件与<上下文中提到的文件相同-param> web.xml中的contextConfigLocation

This configuration file is the same one that gets mentioned as the <context-param>contextConfigLocation in your web.xml

如果您不使用Spring，可以创建JAX-RS服务器以编程方式使用：

In case you are not using Spring, the creation of the JAX-RS server can be done programmatically using:

JAXRSServerFactoryBean sf = new JAXRSServerFactoryBean();
sf.setResourceClasses(abc.class);

List providers = new ArrayList();
sf.setProviders(providers);
sf.setAddress(ENDPOINT_ADDRESS);

server = sf.create(); 

但是我没有看到没有Spring使用CXF的意义。

But I don't see the point of using CXF without Spring.
