我是Apache CXF的新手。我看到框架提供了自动发现功能，因此我更改了我的工作沙盒Web应用程序的cxf（版本3.1.9）配置文件cxf.config.xml：
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:jaxrs="http://cxf.apache.org/jaxrs"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://cxf.apache.org/jaxrs http://cxf.apache.org/schemas/jaxrs.xsd">
<!-- <jaxrs:server id="sec" address="/"> -->
<!-- <jaxrs:serviceBeans> -->
<!-- <bean id="fence" class="edu.pezzati.sec.WebBoundary"/> -->
<!-- <bean id="auth" class="edu.pezzati.sec.SSOIdentityService"/> -->
<!-- </jaxrs:serviceBeans> -->
<!-- <jaxrs:providers> -->
<!-- <ref bean="secjsonprovider"/> -->
<!-- </jaxrs:providers> -->
<!-- </jaxrs:server> -->
<!-- <bean id="secjsonprovider" class="com.fasterxml.jackson.jaxrs.json.JacksonJsonProvider"/> -->
<jaxrs:server id="sec" address="/" basePackages="edu.pezzati.sec"/>
</beans>
正如您所看到的，我评论了jaxrs:server的先前定义，以便将新功能与自动发现结合使用（作为doc shows）。新配置为我提供了一个我无法获得的堆栈跟踪：
