组合JAX-RS和JAX-WS

Question

是否有框架、库或技术将JAX-RS和JAX-WS (或等效功能)组合成一个组合服务，其方式类似于在WCF中为同一服务使用两个端点(一个SOAP和一个REST)？

Answer 1

Apache CXF可以完成这项工作。有关更多信息，请访问http://cxf.apache.org/docs/frontends.html

Answer 2

这可以通过标准的tomcat配置来实现。只需对服务使用单独的URL即可。我决定把JAX-WS服务放在"SOAP/“后面，把其他的放在小写字母后面。如果你想在URL中使用"rest“，那就更简单了，但是对于终端用户来说就不是那么好了。不要忘了添加sun-jaxws.xml。我保留了‘`init params’，因为它们对于标准化的URL很有用。如果您愿意，您可以将它们全部删除。

添加到Mikhail的答案中，CXF的配置示例。欲了解更多信息，请访问http://cxf.apache.org/docs/jax-rs-and-jax-ws.html#JAX-RSandJAX-WS-JAXRSandJAXWS。

  <!-- JAX-RS -->
  <jaxrs:server id="customerService" address="/">
    <jaxrs:serviceBeans>
      <ref bean="customerService" />
    </jaxrs:serviceBeans>
  </jaxrs:server>

  <!-- JAX-WS -->
  <jaxws:endpoint implementor="#customerService"
    address="/CustomerWorld" wsdlLocation="..."/>

  <bean id="customerService" class="demo.jaxrs.server.CustomerService" />
