java Jax-ws、spring 和 SpringBeanAutowiringSupport

Jax-ws, spring and SpringBeanAutowiringSupport

提问by EugeneP

although in my @Webservice class I extend SpringBeanAutowiringSupport, autowiring simply does not work for Spring 2.5, tomcat6.

尽管在我的@Webservice 类中我扩展了 SpringBeanAutowiringSupport，但自动装配对于 Spring 2.5、tomcat6 根本不起作用。

nothing is injected.

什么都没有注入。

I tested those beans autowiring in main method, using classpathcontext, everything is injected fine. But not for jax-ws endpoint.

我在 main 方法中测试了这些 bean 的自动装配，使用 classpathcontext，一切都被注入了。但不适用于 jax-ws 端点。

do you have ideas?

你有想法吗？

I'm guessing that you're using this config element:

我猜你正在使用这个配置元素：

<context:annotation-config />

But to enable support for the @Endpoint annotation, you must add this element:

但是要启用对 @Endpoint 注释的支持，您必须添加此元素：

<context:component-scan base-package="" />

I've found the solution. The problem is that Spring doesn't autowire beans for @WebServiceclasses (as found on other forums it might be a current bug).

我找到了解决方案。问题是 Spring 不会为@WebService类自动装配 bean （如在其他论坛上发现的那样，它可能是当前的错误）。

The solution:

解决办法：

Use org.springframework.beans.factory.config.AutowireCapableBeanFactory.classinstead of using @Autowiredannotation for injecting your beans (e.g. @Service, @Repositoryetc).

使用org.springframework.beans.factory.config.AutowireCapableBeanFactory.class而不是使用@Autowired注解来注入您的 bean（例如@Service，@Repository等）。

So:

所以：

1. include @ResourceWebServiceContext

   @Resource
   private WebServiceContext context;  
   

2. use it for getting your bean

   MyDAO myDAO = null;
   ServletContext servletContext = (ServletContext) context
       .getMessageContext().get("javax.xml.ws.servlet.context");
   WebApplicationContext webApplicationContext = WebApplicationContextUtils
       .getRequiredWebApplicationContext(servletContext);
   myDAO = (MyDAO) webApplicationContext
       .getAutowireCapableBeanFactory().getBean("myDAO");
   

   MyDAOclass can be as follows:

   @Service
   @Qualifier("myDAO")    
   @Transactional
   public class MyDAO {
       private HibernateTemplate hibernateTemplate;
   
       @Required
       @Autowired
       public void setSessionFactory(SessionFactory sessionFactory) {
           this.hibernateTemplate = new HibernateTemplate(sessionFactory);
       }
   
       public MyInfo getMyInfo(Long id){
           return this.hibernateTemplate.get(MyInfo.class, id);
       }
   
       //...
   }
   

3. after this you can use myDAOobject in the @WebMethodmethod.

1. 包括 @ResourceWebServiceContext

   @Resource
   private WebServiceContext context;  
   

2. 用它来获取你的豆子

   MyDAO myDAO = null;
   ServletContext servletContext = (ServletContext) context
       .getMessageContext().get("javax.xml.ws.servlet.context");
   WebApplicationContext webApplicationContext = WebApplicationContextUtils
       .getRequiredWebApplicationContext(servletContext);
   myDAO = (MyDAO) webApplicationContext
       .getAutowireCapableBeanFactory().getBean("myDAO");
   

   MyDAO类可以如下：

   @Service
   @Qualifier("myDAO")    
   @Transactional
   public class MyDAO {
       private HibernateTemplate hibernateTemplate;
   
       @Required
       @Autowired
       public void setSessionFactory(SessionFactory sessionFactory) {
           this.hibernateTemplate = new HibernateTemplate(sessionFactory);
       }
   
       public MyInfo getMyInfo(Long id){
           return this.hibernateTemplate.get(MyInfo.class, id);
       }
   
       //...
   }
   

3. 在此之后，您可以myDAO在@WebMethod方法中使用对象。

I don't know if it's the same case as everyone else. It worked for me by changing the order of the listeners in web.xml. Putting the ContextLoaderListener before WSServletContextListener resolved the issue.

不知道是不是和大家一样。它通过更改 web.xml 中侦听器的顺序对我有用。将 ContextLoaderListener 放在 WSServletContextListener 之前解决了这个问题。

It would be better if you used some reference implementation, like Metro, Axis2, apache-cxf for easy configuration of such endpoint on web service.

如果您使用一些参考实现会更好，例如 Metro、Axis2、apache-cxf 以便在 Web 服务上轻松配置此类端点。
