java - 无法访问 WSDL 端点

Question

我是 SOAP Web 服务的新手。我正在开发一个项目，该项目使用 Spring 框架进行依赖项注入(inject)，并使用 JAX WS 创建端点并执行一些操作。

我在创建端点的类中使用依赖注入(inject)。 当我运行该应用程序时，出现以下错误。

这是堆栈跟踪

No qualifying bean of type [com.wex.gbp.service.EmployeeService] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

这就是我创建端点的地方。

@WebService(serviceName = "LookUpServiceBeanService", portName = "LookUpServiceBeanPort", name = "LookUpService", targetNamespace = "http://namespaceurl.com/")
@SOAPBinding(style = Style.DOCUMENT)
@HandlerChain(file = "chain.xml")
    @Component
    public class LookUpServiceEndpoint extends SpringBeanAutowiringSupport {

        private static final Logger LOGGER = LoggerFactory.getLogger(LookUpServiceEndpoint.class);



@Autowired
@Qualifier(value="employeeService")
private EmployeeService employeeService;
    // Other methods

    }

我确实有具有相同限定符名称的服务类。 我的 web.xml 包含

 <servlet>
        <servlet-name>LookUpService</servlet-name>
        <servlet-class>com.ws.endpoints.LookUpServiceEndpoint</servlet-class>
    </servlet>

    <servlet-mapping>
        <servlet-name>LookUpService</servlet-name>
        <url-pattern>/services/LookUpService</url-pattern>
    </servlet-mapping>

当我尝试访问 url“http://localhost:8080/Project_WSDL/services/LookUpService?wsdl”时，出现错误。

请帮我解决这个问题？

Answer 1

终于，我能够解决这个问题了。我之前的代码几乎没有问题。

1. Spring 和 Jax ws 集成不依赖。
2. web.xml 中 W 的监听器
3. 在 applicationContext.xml 中配置 Web 服务 URL

对于第一个问题，我添加了以下依赖项

<dependency>
            <groupId>com.sun.xml.ws</groupId>
            <artifactId>jaxws-rt</artifactId>
            <version>2.2.3</version>
        </dependency>

        <!-- Library from java.net, integrate Spring with JAX-WS -->
        <dependency>
            <groupId>org.jvnet.jax-ws-commons.spring</groupId>
            <artifactId>jaxws-spring</artifactId>
            <version>1.8</version>
</dependency>

对于第二个，我在 web.xml 中添加了以下几行

<servlet>
        <servlet-name>jaxws-servlet</servlet-name>
        <servlet-class>
            com.sun.xml.ws.transport.http.servlet.WSSpringServlet
        </servlet-class>
    </servlet>

    <servlet-mapping>
        <servlet-name>jaxws-servlet</servlet-name>
        <url-pattern>/services/LookUpService</url-pattern>
    </servlet-mapping>

最后，我在 applicationContext.xml 中添加了绑定(bind) url

<wss:binding url="/services/LookUpService">
        <wss:service>
            <ws:service bean="#lookUpServiceEndpoint" />
        </wss:service>
    </wss:binding>

对我来说，这就是问题所在。但对其他人来说可能会有所不同。
