JBossWS中的弹簧配置

Question

我想使用JBossWS（本地堆栈）公开Web服务，并利用Spring的依赖注入。这里是我的代码净化的缩小版本：

web.xml中：

<?xml version="1.0" encoding="UTF-8"?> 
<web-app xmlns="http://java.sun.com/xml/ns/j2ee" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd" 
    version="2.4"> 

    <display-name>Test Service</display-name> 

    <context-param> 
     <param-name>contextConfigLocation</param-name> 
     <param-value> 
      /WEB-INF/applicationContext.xml 
     </param-value> 
    </context-param> 

    <listener> 
     <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> 
    </listener> 

    <servlet>  
     <servlet-name>EndpointService</servlet-name> 
     <servlet-class>com.blah.webservice.EndpointService</servlet-class> 
    </servlet> 
    <servlet-mapping> 
     <servlet-name>EndpointService</servlet-name> 
     <url-pattern>/*</url-pattern> 
    </servlet-mapping> 
</web-app> 

的applicationContext.xml：

<?xml version="1.0" encoding="UTF-8"?> 
<beans xmlns="http://www.springframework.org/schema/beans" 
     xmlns:context="http://www.springframework.org/schema/context" 
     xmlns:aop="http://www.springframework.org/schema/aop" 
     xmlns:tx="http://www.springframework.org/schema/tx" 
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
     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"> 

    <context:spring-configured /> 
    <context:load-time-weaver /> 
    <context:annotation-config /> 

    <context:component-scan base-package="com.blah.webservice" /> 
</beans> 

EndpointService.java

package com.blah.webservice; 

import javax.jws.WebMethod; 
import javax.jws.WebService; 
import javax.jws.soap.SOAPBinding; 

import org.springframework.beans.factory.annotation.Autowired; 
import org.springframework.stereotype.Service; 

@Service 
@WebService 
@SOAPBinding(parameterStyle=SOAPBinding.ParameterStyle.BARE) 
public class EndpointService { 

    private TestService testService; 

    public EndpointService() {} 

    @Autowired 
    public EndpointService(TestService testService) { 
     this.testService = testService;   
    } 

    @WebMethod 
    public String endpointEcho(String echo) { 
     return echo; 
    } 

    @WebMethod 
    public String serviceEcho(String echo) { 
     return testService.serviceEcho(echo); 
    } 
} 

TestService.java：

package com.blah.webservice; 

import org.springframework.stereotype.Service; 

@Service 
public class TestService { 

    public TestService() {} 

    public String serviceEcho(String echo) { 
     return echo; 
    } 
} 

当我建立这个并部署到JBoss，它启动就好了，我可以看到春天预实例化我的课，但是当我发布到Web服务调用， endpointEcho按预期工作，而serviceEcho引发NullPointerException。看起来，当JBossWS实例化端点类时，它没有发现我的Spring配置。有没有一种简单的方法可以告诉JBossWS Spring？我觉得我要么缺少一些非常小的细节，要么我接近这一切都是错误的。有任何想法吗？

您的服务必须扩展SpringBeanAutowiringSupport才能够利用自动装配支持。
