cxf和spring集成的一些事
环境：
cxf-2.1.3，jdk6，jboss7.0.2，spring3.0.6
用cxf+spring开发web service程序很简单，不过有一些集成问题要注意。在此把这几天发现的一些总结一下，最后有一个遗留的问题
1、关于bean的声明
要发布或者要调用的web service接口，需要用@WebService注解声明。不过要注意的是，@WebService注解不会把类声明为spring的bean
可以声明为bean的方式有以下4个：
<jaxws:endpoint>
<jaxws:client>
<bean id="" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:jaxws="http://cxf.apache.org/jaxws"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/jaxws http://cxf.apache.org/schemas/jaxws.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" /><context:component-scan base-package="com.huawei.framework" /><bean id="helloWorldImpl" ref="remedy" /></bean><jaxws:endpoint id="helloWorld" address="/HelloWorld"implementor="#helloWorldImpl" /><jaxws:client id="remedy"service/></beans>
用这种写法，虽然HelloWorldImpl类已经被声明成bean了，但是注入是失败的
准确来说，在spring容器中存在有HelloWorldImpl对应的bean，并且相关的依赖也已经注入了。但是cxf框架得到的HelloWorldImpl，与上述的bean不是同一个对象，这个HelloWorldImpl对象可能是用反射或者其他机制创建出来的，没有任何组件被注入
正确的写法：
在implementor属性中，用#beanName，这样的话，cxf框架得到的HelloWorldImpl，就是spring容器持有的那个bean。当然这有个前提，就是系统中已经存在这个bean。用<bean id="">或者@Component都是OK的，这里支持注解
3、上面说的是<jaxws:endpoint>，比较简单。但是<jaxws:client>就比较麻烦
我目前感觉，<jaxws:client>声明的bean，没办法在别的bean里用@Autowired注入，只能用<bean id="">的方式来注入
用这种<bean id="">的方式就可以
用@Autowired加@Component的方式来做，就不行，报以下异常：

说自动注入失败，因为找不到RemedyWebServiceCM类型的bean
试了很久，完全搞不定。也想不通是为啥，因为RemedyWebServiceCM这个类型的bean，明明已经用<jaxws:client>声明了，而且用配置文件的方式也是能搞定的 implementor="com.huawei.framework.webservice.HelloWorldImpl" />
cxf2.5.2已经支持了这种写法了
