Java 注入上下文HttpServletRequest原因“；接口org.glassfish.hk2.api.ProxyCtl在类加载器中不可见；（泽西岛2.21，weblogic 12.1.3）

我在WebLogic12c（12.1.3）上使用jersey 2.21来提供Rest。Rest类在不注入上下文HttpServletRequest/HTTPServletResponse的情况下工作正常。但是一旦注入上下文，调用服务时会抛出“interface org.glassfish.hk2.api.ProxyCtl不可见于类加载器”错误

下面是课堂：

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.QueryParam;
import javax.ws.rs.core.Context;
import javax.ws.rs.core.MediaType;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Component;

@Component
@Path("test")
public class TestResource {
Logger logger = LoggerFactory.getLogger(TestResource.class);


@Context HttpServletResponse resp; 
@Context HttpServletRequest request; 


/**
 * Test site connectivity. Return parameter txt's content in reply
 * @param content
 * @return 
 */
@GET
@Path("/tryMe")
@Produces(MediaType.TEXT_PLAIN)
public String echoTest(@QueryParam("txt") String content) { 
    System.out.println("Try me reach.");
    System.out.println("from client: "+request.getRemoteAddr()); 


    return content;
}

}

如果注释掉这两个上下文，则调用tryMe Restful时不会出错。
使用两个上下文时，调用tryMe restful将抛出以下错误：

我遇到了同样的问题，并找到了解决办法：我将请求注入移动到方法声明，这对我来说是可行的：

    @GET
    public void test(@Context HttpServletRequest request){
        ...
    }

---

我发现将其作为组件似乎存在一些问题，因此我不得不删除注释@Component。然后错误消失了。我看到glassfish中提到了一些问题：

但我不确定这些是否已经修复或与泽西岛有关。如果您可以不使用@Component，那么这可能是目前最好的解决方案。

检查，如果您必须使用静态访问，您可以使用静态访问

HttpServletRequest request= 
((ServletRequestAttributes) RequestContextHolder.currentRequestAttributes()).getRequest();

---

在WebLogic12c中部署rest项目时，我也遇到了同样的问题，正如jediz所建议的那样，尝试使用该解决方案。此外，还必须在web.xml中添加侦听器

 <listener>
    <listener-class>org.springframework.web.context.request.RequestContextListener</listener-class>
  </listener>

org.springframework.web.context.request.RequestContextListener

您找到解决此异常的解决方案了吗？找到解决方案了吗？可能是重复的一个Jersey bug，但它仍然存在：此解决方案不足以解决注射问题。@Mohammad Abdullah。，添加此项后，问题也存在。org.glassfish.jersey.internal.Errors日志错误警告：已检测到以下警告：警告：检测到未知HK2故障：4个java.lang.IllegalArgumentException中的多异常堆栈1：接口org.glassfish.HK2.api.ProxyCtl在类中不可见loader@Madhesh ,在部署RESTfulWeb服务应用程序之前，v必须在weblogic中注册web服务。部署此war后，请遵循此操作，然后重新启动托管web服务器并部署web服务应用程序。
