Cannot inject ResourceInfo into ContainerRequestFilter - jersey

I'm trying to implement a ContainerRequestFilter that checks some stuff. Ultimately, it shall authenicate a token, but I'm not there yet. The filter runs on a Grizzly HTTP Server (Grizzly 2.3.4) and sits in front of a JAX-RS resource (Jersey 2.0). I am also using Guice 3.0.
When I'm trying to inject javax.ws.rs.container.ResourceInfo into the filter, it is null.
import javax.ws.rs.container.ContainerRequestContext;
import javax.ws.rs.container.ContainerRequestFilter;
import javax.ws.rs.container.ResourceInfo;
import javax.ws.rs.core.Context;
import java.io.IOException;
public class MyRequestFilter implements ContainerRequestFilter {
#Context
private ResourceInfo resourceInfo;
public void filter(ContainerRequestContext containerRequestContext) throws IOException {
String method = containerRequestContext.getMethod();
System.out.println("method = " + method);
if("OPTIONS".equals(method)) return;
System.out.println("DO SECURITY");
}
}
Injecting the request into a JAX-RS resource, the injection is successful and I can work with it.
What am I doing wrong?

To enable injection in ContainerRequestFilter you have to annotate it as #Provider, then it works
#Provider
public class MyRequestFilter implements ContainerRequestFilter {
#Context
private ResourceInfo resourceInfo;
...
}

Dependency injection does not work in RestClientBuilderListener

I followed the rest client guide in Quarkus web site. It works fine. But when registering a global provider using the ServiceLoader pattern, as described in the specification, the CDI beans injection did not work, they are all null. I downloaded the example and simply added the following classes:
package org.acme.rest.client;
import org.eclipse.microprofile.rest.client.ext.ResponseExceptionMapper;
import javax.enterprise.context.ApplicationScoped;
import javax.ws.rs.core.Response;
#ApplicationScoped
public class MyExceptionMapper implements ResponseExceptionMapper<Exception> {
#Override
public Exception toThrowable (Response response) {
return new Exception();
}
}
package org.acme.rest.client;
import org.eclipse.microprofile.rest.client.RestClientBuilder;
import org.eclipse.microprofile.rest.client.spi.RestClientBuilderListener;
import javax.enterprise.context.ApplicationScoped;
import javax.inject.Inject;
#ApplicationScoped
public class MyListener implements RestClientBuilderListener {
#Inject MyExceptionMapper myExceptionMapper;
#Override
public void onNewBuilder (RestClientBuilder builder) {
builder.register(myExceptionMapper);
}
}
I also added the file META-INF/services/org.eclipse.microprofile.rest.client.spi.RestClientBuilderListener with the content org.acme.rest.client.MyListener. The MyListener onNewBuilder method is invoked, but the injected provider MyExceptionMapper is null. How to register a global provider in Quarkus client?
Implementation of RestClientBuilderListener are not CDI beans - they are just objects that are created via the normal Java ServiceLoader mechanism when RestClientBuilder is being used.
So if you want to obtain CDI beans when onNewBuilder is called, you can do something like:
CDI.current().select(MyExceptionMapper.class).get()
Furthermore, you need to annotate MyExceptionMapper with #Provider, not #ApplicationScoped.

Using Spring autowired Service classes within a Liferay Indexer

I am using Spring #Service classes in my liferay portlet to get and store data. They are injected using the #autowired annotation. Everything is working as expected. When I am trying to use that same approach in a Liferay BaseIndexer subclass (to put data in the search engine) the #autowired annotated classes are all null (not injected).
Is there a way to get these Service classes in the Indexer ?
Best regards,
Daniel
This indexer is not instantiated by Spring, so you won't be able to autowired your service.
But, you could implement a custom ApplicationContextProvider (implementing Spring ApplicationContextAware) and use it in order to inject your service. It should be easy.
You should start creating this class, and let Spring to discover it (be sure that this class is scanned by spring):
import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
import org.springframework.stereotype.Component;
/**
* Created by Alberto Martínez Ballesteros on 18/03/16.
*/
#Component("applicationContextProvider")
public class ApplicationContextProvider implements ApplicationContextAware {
private static ApplicationContext context = null;
public static ApplicationContext getApplicationContext() {
return context;
}
#Override
public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
context = applicationContext;
}
}
Then, you can use this ApplicationContextProvider to inject your service within the indexer class:
For example:
public class CategoryIndexer extends BaseIndexer {
private CategoryService categoryService;
[....]
#Override
protected void doReindex(String className, long classPK) throws Exception {
if (categoryService == null) {
initService();
}
final Category category = categoryService.get(classPK);
doReindex(category);
}
private void initService() {
categoryService = (CategoryService) ApplicationContextProvider.getApplicationContext()
.getBean("categoryService");
}
[....]
As you can see, you can not use #Autowired in this way, but you can inject your bean anyway.
Regards.

How to access wicket session from Jersey-2 request filter?

In Jersey 1.x we accessed the Wicket session from a (Jersey) session attribute, as described here https://stackoverflow.com/a/15767824/1399659.
In moving to Jersey 2.x it seems the proper pattern to use a ContainerRequestFilter, which also allows Spring bean injection as well. We have this working successfully by including
<param-name>jersey.config.server.provider.packages</param-name>
as an init-param to the ServletContainer and using the #Provider annotation on a ContainerRequestFilter implementation. But this container filter is a singleton, and it's not possible to inject the HttpServletRequest into this (see JERSEY-2114)
In the filter() method we have access to the ContainerRequestContext but can't access the HttpServletRequest from there.
So is there a way to either:
Enable Spring bean injection within a servlet filter (with Jersey too)?
Access the servlet request from within a ContainerRequestFilter?
Access wicket session from Spring-bean-aware object with Jersey filtering ability some other way?
`
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);
}
...
}
`
Thanks in advance
Fixed in Jersey 2.4:
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;
}
});
}
}
You can also register the filter without using #Provider annotation:
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);
}
}
Note: Glassfish 4.0.0 uses old Jersey 2.0.
You will have to upgrade Jersey using these tips (it's not proven to work well). Or the better way is to download nightly build of Glassfish 4.0.1. but it's not completely stable at the moment. I hope the new version will be released soon.

#Autowired not working on jersey resource

workflowService is null. The bean configuration is correct because manual injection works fine in other portions of the application.
Here's my resource:
#Path("/workflowProcess")
#Consumes({MediaType.APPLICATION_JSON})
#Produces({MediaType.APPLICATION_JSON})
public class WorkflowProcessResource {
#Autowired
WorkflowService workflowService;
#Autowired
WorkflowProcessService workflowProcessService;
#GET
#Path ("/getWorkflowProcesses/{uuid}")
public Collection<WorkflowProcessEntity> getWorkflows (#PathParam("uuid") String uuid) {
WorkflowEntity workflowEntity = workflowService.findByUUID(uuid);
return workflowEntity.getWorkflowProcesses();
}
}
From what I keep finding on Google on sites like http://www.mkyong.com/webservices/jax-rs/jersey-spring-integration-example/, it looks like ContextLoaderListener is the key. But I've already added that to the application context.
import com.sun.jersey.spi.container.servlet.ServletContainer;
import com.sun.jersey.spi.spring.container.servlet.SpringServlet;
import org.atmosphere.cpr.AtmosphereFramework;

final HttpServer server = HttpServer.createSimpleServer(".", 8181);
WebappContext ctx = new WebappContext("Socket", "/");
//enable annotation configuration
ctx.addContextInitParameter("contextClass", "org.springframework.web.context.support.AnnotationConfigWebApplicationContext");
ctx.addContextInitParameter("contextConfigLocation", "com.production");
//allow spring to do all of it's stuff
ctx.addListener("org.springframework.web.context.ContextLoaderListener");
//add jersey servlet support
ServletRegistration jerseyServletRegistration = ctx.addServlet("JerseyServlet", new SpringServlet());
jerseyServletRegistration.setInitParameter("com.sun.jersey.config.property.packages", "com.production.resource");
jerseyServletRegistration.setInitParameter("com.sun.jersey.spi.container.ContainerResponseFilters", "com.production.resource.ResponseCorsFilter");
jerseyServletRegistration.setInitParameter("com.sun.jersey.api.json.POJOMappingFeature", "true");
jerseyServletRegistration.setLoadOnStartup(1);
jerseyServletRegistration.addMapping("/api/*");
What you need here, I think, is #InjectParam instead of #Autowired
#InjectParam worked fine instead of #Autowired, with a slight change
#InjectParam cannot be applied to the constructor itself hence has to be applied to the arguments to the constructor.
public OrderService(#InjectParam OrderValidationService service,
#InjectParam OrderCampaignService campaignService) {
this.service = service;
this.submissionErrorHandler = submissionErrorHandler;
this.campaignService = campaignService;
}

Spring Pre/Post method security annotations not working

I can't seem to get Spring Pre/Post method security annotations to work. I've read every related stackoverflow question on the topic, and the main suggestion is to ensure that global-method-security is enabled in the same context as the beans which you wish to secure. I have the following my dispatcher-servlet.xml:
<context:component-scan base-package="com.package.path" />
<context:annotation-config />
<security:global-method-security pre-post-annotations="enabled" />
The beans in question are in "com.package.path". I know that Spring is creating instances of them correctly, as injection is working just fine and requests are being serviced by the intended classes.
So, here's an example service class in "com.package.path":
#Controller
#RequestMapping("/article")
public class ArticleServiceImpl extends GWTController implements ArticleService {
#Autowired
public ArticleServiceImpl(DataSource ds) {
}
#Override
#PreAuthorize("hasRole('ROLE_BASIC_USER')")
public Article save(Article article) {
}
}
The annotation on the save method does not work. A few important notes:
I'm using GWT, though from what I've read, that shouldn't matter much.
I have method security working perfectly well in another, similar project. The only difference is that there is a DAO layer in the other project, which is not present in this one. It's in this layer that I have annotation security working. However, it shouldn't matter what "layer" this is, as long as Spring is responsible for creation of the beans, right?
The interface "ArticleService" above is a GWT service interface. I've tried putting the annotation there, but that doesn't work either.
Here's my GWTController class, referenced above, if needed:
package com.areahomeschoolers.baconbits.server.spring;
import javax.servlet.ServletConfig;
import javax.servlet.ServletContext;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.context.ServletConfigAware;
import org.springframework.web.context.ServletContextAware;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.Controller;
import com.areahomeschoolers.baconbits.server.util.ServerContext;
import com.google.gwt.user.client.rpc.RemoteService;
import com.google.gwt.user.server.rpc.RemoteServiceServlet;
/**
* Spring controller class that handles all requests and passes them on to GWT. Also initializes server context.
*/
public class GWTController extends RemoteServiceServlet implements ServletConfigAware, ServletContextAware, Controller, RemoteService {
private static final long serialVersionUID = 1L;
protected ServletContext servletContext;
#Override
public ServletContext getServletContext() {
return servletContext;
}
// Call GWT's RemoteService doPost() method and return null.
#Override
public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response) throws Exception {
// load our ServerContext with current request, response, session, user, appContext, etc.
ServerContext.loadContext(request, response, servletContext);
try {
doPost(request, response);
} finally {
ServerContext.unloadContext();
}
return null; // response handled by GWT RPC over XmlHttpRequest
}
#Override
public void setServletConfig(ServletConfig conf) {
try {
super.init(conf);
} catch (ServletException e) {
e.printStackTrace();
}
}
#Override
public void setServletContext(ServletContext servletContext) {
this.servletContext = servletContext;
}
#Override
protected void checkPermutationStrongName() throws SecurityException {
return;
}
#Override
protected void doUnexpectedFailure(Throwable e) {
e.printStackTrace();
super.doUnexpectedFailure(e);
}
}
Security aspect provided by Spring Security inherits all limitations of Spring Framework proxy-based AOP support. In particular, aspects are not applied to calls that happen "inside" the objects (unless you use AspectJ weaving), see 7.6.1 Understanding AOP proxies.
So, if you want to use security aspect this way, you need to use GWT integration mechanism that make calls to your service from the outside, i.e. a mechanism that doesn't require your services to extend RemoteServiceServlet.
Something like spring4gwt should work fine.
