Question

我在weblogic 12c（12.1.3）上使用jersey 2.21来提供Rest。 Rest类工作正常，无需注入上下文HTTPServeletRequest / HTTPServletResponse。但是一旦注入上下文，就会抛出＆＃34;接口org.glassfish.hk2.api.ProxyCtl在类加载器中是不可见的＃34;错误，在调用服务时。

这是班级：

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，则在调用tryMe Restful时没有错误当使用两个上下文时，调用tryMe restful会抛出以下错误：

Answer 1

我遇到了同样的问题并找到了解决方法：我将请求注入方法声明并为我工作：

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

Answer 2

我发现将它作为Component似乎存在一些问题，所以我不得不删除注释@Component。然后错误就消失了。我看到glassfish中提到了一些问题：Glassfish issue

但我不确定这些是否已经修复或与泽西岛有关。如果你没有@Component，那么这可能是最好的解决方案。

Answer 3

检查duplicate topic，如果你必须使用静态访问

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

Answer 4

在weblogic 12c中部署rest项目时我也遇到了同样的问题，jediz建议尝试使用该解决方案。此外，您必须在web.xml中添加侦听器。

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

注入上下文HttpServletRequest原因＆＃34;接口org.glassfish.hk2.api.ProxyCtl在类加载器中不可见＆＃34; （球衣2.21，weblogic 12.1.3）
