无法通过 @Context jersey2.x 和 weblogic 12.1.3 在 ContainerRequestFilter 中注入 HttpServletRequest

Question

我无法使用 weblogic 12.1.3 在 Jersey 2.22.1 中通过 @Context 在 ContainerRequestFilter 中注入 HttpServletRequest。我研究了几个存在这个问题的地方，在很多地方我发现它在 Jersey 2.4 中得到了修复，但我仍然看到这个问题。附上我的实现和代码。如果我遗漏了什么，请告诉我。

授权过滤器

@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");

我看到的错误如下

Root cause of ServletException.
A MultiException has 4 exceptions.  They are:
1. java.lang.IllegalArgumentException: interface org.glassfish.hk2.api.ProxyCtl is not visible from class loader
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
3. java.lang.IllegalArgumentException: While attempting to resolve the dependencies of xyz.xyz.xyz.xyz.xyz.xyz.xyz.AuthFilter errors were found
4. java.lang.IllegalStateException: Unable to perform operation: resolve on xyz.xyz.xyz.xyz.xyz.xyz.xyz.AuthFilter

如果有任何解决此问题的方法，请告诉我。

Answer 1

这似乎是 Weblogic 12.1.3 的一个错误。我尝试升级到 Weblogic 12.2.1 并使用 @Context 注入 HttpServletRequest 即使在 ContainerRequestFilter 内也能正常工作。

Answer 2

作为@Context、@Inject 或@Autowire 通常首选注入的替代方法，您可以使用 Spring 的静态方法inject HttpServletRequest into a request-scoped bean：

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

请注意，这种方法并不理想，因为静态方法会使您的代码更难测试，并使您的代码更加僵化。
