spring – 如何从Jersey-2请求过滤器访问wicket会话?

在Jersey 1.x中,我们从(Jersey)会话属性访问了Wicket会话,如https://*.com/a/15767824/1399659所述.

在转向Jersey 2.x时,似乎使用ContainerRequestFilter的正确模式,也允许Spring bean注入.我们成功地通过包括这项工作

<param-name>jersey.config.server.provider.packages</param-name>

作为ServletContainer的init-param并在ContainerRequestFilter实现上使用@Provider批注.但是这个容器过滤器是一个单例,并且不可能将HttpServletRequest注入其中(参见JERSEY-2114)

在filter()方法中,我们可以访问ContainerRequestContext,但无法从那里访问HttpServletRequest.

那么有没有办法:

>在servlet过滤器中启用Spring bean注入(也使用Jersey)?
>从ContainerRequestFilter中访问servlet请求?
>以其他方式从具有泽西过滤能力的Spring-bean感知对象访问wicket会话?

import java.io.IOException;

import javax.servlet.http.HttpSession;
import javax.ws.rs.container.ContainerRequestContext;
import javax.ws.rs.container.ContainerRequestFilter;
import javax.ws.rs.core.Response;
import javax.ws.rs.core.Response.Status;
import javax.ws.rs.ext.Provider;

import org.apache.wicket.injection.Injector;

@Provider
public class SecurityContextFilter implements ContainerRequestFilter {

//@Context
//HttpServletRequest webRequest;

@Override
public void filter(ContainerRequestContext requestContext) throws IOException {
    //HttpSession httpSession = webRequest.getSession();
    //MyWicketSession mySession = (MyWicketSession) httpSession.getAttribute("wicket:" + BaseConstants.WICKET_FILTER_NAME + ":session");
    //doAuthCheck(mySession, requestContext);
}
...
}

解决方法:

泽西岛的Fixed

import javax.annotation.Priority;
import javax.ws.rs.Priorities;

@Provider
@Priority(Priorities.AUTHENTICATION)
public class AuthRequestFilter implements ContainerRequestFilter {
    @Context
    HttpServletRequest webRequest;

    @Override
    public void filter(ContainerRequestContext requestContext) throws IOException {
        final HttpSession session = webRequest.getSession();

        requestContext.setSecurityContext(new SecurityContext() {
            @Override
            public Principal getUserPrincipal() {
                return new PrincipalImpl((String)session.getAttribute("USER_NAME"));
            }

            @Override
            public boolean isUserInRole(String s) {
                return false;
            }

            @Override
            public boolean isSecure() {
                return false;
            }

            @Override
            public String getAuthenticationScheme() {
                return null;
            }
        });
    }
}

您也可以在不使用@Provider注释的情况下注册过滤器:

import org.glassfish.jersey.server.ResourceConfig;
import javax.ws.rs.ApplicationPath;

/**
 * Root REST resource class.
 */
@ApplicationPath("/rest")
public class RootResource  extends ResourceConfig {
    /**
     * Initializes all resources from REST package.
     */
    public RootResource() {
        packages("com.example.rest");
        register(AuthRequestFilter.class);
    }
}

注意:Glassfish 4.0.0使用旧的Jersey 2.0.
你将不得不使用these tips升级泽西岛(它没有被证明效果很好).或者更好的方法是下载nightly build of Glassfish 4.0.1.,但目前还不完全稳定.我希望新版本即将发布.
