找不到线程绑定请求

Question

使用 Apache CXF 依赖cxf-rt-transports-http-jetty-3.1.4.jar来测试 JAXRS 服务。以下是Junit注释-

@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
@ContextConfiguration(locations = {"classpath:test-spring-context.xml"})

web.xml(不要认为web.xml是由@WebAppConfiguration加载的，但它在标准目录src/main/webapp/WEB-INF/web.xml中(

    <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!-- listener to inject HttpServlet Request -->
 <listener>
    <listener-class>org.springframework.web.context.request.RequestContextListener</listener-class>
</listener>
<!-- CXF Servlet -->
<servlet>
    <servlet-name>CXFServlet</servlet-name>
    <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
</servlet>
<servlet-mapping>
    <servlet-name>CXFServlet</servlet-name>
    <url-pattern>/service/*</url-pattern>
</servlet-mapping>

码头配置-

<httpj:engine-factory bus="cxf" id="port9191">
    <httpj:engine port="9191">
        <httpj:threadingParameters minThreads="5"
            maxThreads="15" />
        <httpj:handlers>
            <bean class="org.eclipse.jetty.server.handler.DefaultHandler" />
        </httpj:handlers>
        <httpj:sessionSupport>true</httpj:sessionSupport>
    </httpj:engine>
</httpj:engine-factory>

尝试从对象读取标头时出现以下异常@Autowired HttpServletRequest request request.getHeader("ApplicationName"); -

java.lang.IllegalStateException: No thread-bound request found: Are you referring to request attributes outside of an actual web request, or processing a request outside of the originally receiving thread? If you are actually operating within a web request and still receive this message, your code is probably running outside of DispatcherServlet/DispatcherPortlet: In this case, use RequestContextListener or RequestContextFilter to expose the current request.

任何帮助将不胜感激！

通过 JAX-RS ContainerRequestFilter 注入的 HttpServletRequest。

import java.io.IOException;
import javax.servlet.http.HttpServletRequest;
import javax.ws.rs.container.ContainerRequestContext;
import javax.ws.rs.container.ContainerRequestFilter;
import javax.ws.rs.core.Context;
import javax.ws.rs.ext.Provider;
import org.springframework.context.i18n.LocaleContextHolder;
import org.springframework.web.context.request.RequestContextHolder;
import org.springframework.web.context.request.RequestContextListener;
import org.springframework.web.context.request.ServletRequestAttributes;
@Provider
public class RequestFilter implements ContainerRequestFilter {
    private static final String REQUEST_ATTRIBUTES_ATTRIBUTE =
            RequestFilter.class.getName() + ".REQUEST_ATTRIBUTES";
    @Context private HttpServletRequest httpRequest;
    @Override
    public void filter(ContainerRequestContext requestContext) throws IOException {
        ServletRequestAttributes attributes = new ServletRequestAttributes(httpRequest);
        httpRequest.setAttribute(REQUEST_ATTRIBUTES_ATTRIBUTE, attributes);
        LocaleContextHolder.setLocale(httpRequest.getLocale());
        RequestContextHolder.setRequestAttributes(attributes);
    }
}
