问题
I was not able to inject HttpServletRequest in ContainerRequestFilter via @Context in Jersey 2.22.1 using weblogic 12.1.3. I researched several places that this issue exists and in many places I see that it is fixed in Jersey 2.4, but I am still seeing this issue. My implementation and code is attached. Please let me know if I am missing anything.
AuthFilter
@Provider
@Priority(Priorities.AUTHENTICATION)
public class AuthFilter implements ContainerRequestFilter {
@Context
HttpServletRequest webRequest;
@Context
HttpServletResponse webResponse;
@Override
public void filter(ContainerRequestContext requestContext) throws IOException {
final HttpSession session = webRequest.getSession();
final String userName = (String)session.getAttribute("USER_NAME");

And the error I see is below

A MultiException has 4 exceptions. They are:

2. java.lang.IllegalArgumentException: While attempting to create a Proxy for javax.servlet.http.HttpServletRequest in scope org.glassfish.jersey.process.internal.RequestScoped an error occured while creating the proxy

Please let me know in case of any workaround for this issue.
回答1:
It seems this is a bug with Weblogic 12.1.3. I tried upgrading to Weblogic 12.2.1 and injecting HttpServletRequest
using @Context
works correctly even inside ContainerRequestFilter
.
回答2:
As an alternative to typically preferred injection by @Context
, @Inject
, or @Autowire
, you can inject HttpServletRequest into a request-scoped bean using Spring's static method:
HttpServletRequest request=
((ServletRequestAttributes) RequestContextHolder.currentRequestAttributes()).getRequest();
Note that this approach is not ideal, because static methods make your code harder to test and make your code more rigid.
