Question

为什么以下CDI在glassfish 3.x.x中的JAX-WS端点中不起作用？从端点访问服务时，我得到一个NPE。

@WebService
public class JaxWsTestEndpoint {

    @Inject
    private MyService service;

    @WebMethod
        public String sayHello(String name) {
        System.out.println("injected service:" + service);
        service.callService();
        return "Hello, " + name + ".";
    }
}

“服务”类定义如下：

@Named("myService")
public class MyService {
     public MyService() {
        System.out.println("init myService.");
     }

    public void callService() {
            System.out.println("calling Service.");
    }
 }

我在WEB-INF中有一个空的beans.xml文件。我用完整的空内容和空的

尝试了它

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://java.sun.com/xml/ns/javaee"  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"      xsi:schemaLocation="http://java.sun.com/xml/ns/javaee      http://java.sun.com/xml/ns/javaee/beans_1_0.xsd">

</beans>

标签。但不知何故，JAX-WS端点中的服务字段在部署之后和接收Web服务请求期间仍为NULL，从而在调用服务时产生NPE。我在这里缺少什么？

Answer 1

您可以尝试从WEB-INF目录中删除sun-jaxws.xml。这种方式帮助了我！

Answer 2

是的，我通过删除sun-jaxws.xml并修改web.xml直接指向我的webservice而不是WSServlet来实现它。

http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd“＆GT;

 <!-- This listener parses a sun specific configuration file (sun-jaxws.xml), which provides the web service
endpoints and connects the WSServlet instance to the services' implementation classes -->
<!--<listener>
    <listener-class>com.sun.xml.ws.transport.http.servlet.WSServletContextListener</listener-class>
</listener> -->

<!-- Delegate requests whose URLs end with the path '/StakeholderWebService' to a WSServlet instance provided by container, which in turn is linked to the JWS runtime --> 
<servlet>
    <servlet-name>StakeholderWebService</servlet-name>
<!--     <servlet-class>com.sun.xml.ws.transport.http.servlet.WSServlet</servlet-class> -->
    <servlet-class>com.werner.stakeholder.webservices.StakeholderWebServiceImpl</servlet-class>
</servlet>
<servlet-mapping>
    <servlet-name>StakeholderWebService</servlet-name>
    <url-pattern>/stakeholderWebService</url-pattern>
</servlet-mapping>
<session-config>
    <session-timeout>120</session-timeout>
</session-config>

在JAX-WS端点中的CDI注入不起作用，导致NPE
