通过扩展SpringBeanAutowiringSupport暴露我的Web服务无法注入@Autowired依赖项。
Web服务部署正常,我可以调用@WebMethod,但由于注入失败,我得到NullPointerException。
我将System.out.println("Consructing XmlContactMapper...");
放在XmlContactMapper的构造函数中(我的一个依赖项是@Autowired)。当我部署Web服务时,我看到调试行,所以我知道正在调用构造函数。但由于某种原因,XmlContactMapper的实例没有被注入到我的ContactServiceImpl xmlMapper属性中。
关于我做错的任何想法?

像@Biji建议的那样,我认为这可能是您的ContactServiceImpl与ContactComponent之间的加载顺序问题
通常,您需要扩展SpringBeanAutowiringSupport的原因是您有一些在Spring容器之外实例化的bean,但您希望它通过Spring解析它的依赖关系。
由于您使用的是Glassfish + Metro,您可以查看Metro Spring集成支持: http://jax-ws-commons.java.net/spring/
使用此路由, com.sun.xml.ws.transport.http.servlet.WSSpringServlet 应该处理与Spring上下文相关的正确加载顺序。

听众的顺序很重要。必须在ContextLoaderListener
之前定义WSServletContextListener
。
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:wsContext.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<listener>
<listener-class>com.sun.xml.ws.transport.http.servlet.WSServletContextListener</listener-class>
</listener>
答案 2 :(得分:0)
正如Zeemee所说,听众定义的顺序至关重要。另外,我必须在<absolute-ordering/>
中添加web.xml
,因为Tomcat 8.0.26不依赖于订单。
