how can i validate user name and password using jersey restful API.
Here is the code Below:
I tried using the HttpRequest and HttpResponse
#POST
#Path("/login")
#Consumes(MediaType.APPLICATION_FORM_URLENCODED)
#Produces(MediaType.APPLICATION_JSON)
public String postLoginJson(#FormParam("userName") String userName,
#FormParam("password") String password) {
String user = null;
try {
user = userObjectJson();
} catch (JSONException e) {
e.printStackTrace();
}
System.out.println("User Name = " + userName);
System.out.println("Password = " + password);
return user;
}
Security is best handled as an aspect independent of your REST resources.
I suggest letting your hosting container or context handle this. Your resources can access this information, as provided by the container.
For information on how to configure your application using JavaEE realms, see https://jersey.java.net/documentation/latest/security.html
For using Spring as a security solution, see

I'm new to spring-security. I understood basics of spring-security about authentication-manager and other stuff.
I'm using angularjs as front end, and spring 3.0.5 as backend.
I want to add spring security for role based authorization to my existing project.
I also want to authenticate user using office 365. So, i created application in https://apps.dev.microsoft.com/ and given redirect URI as my localhost action.
Using my code, I'm able to authenticate using office 365 and able to get username in redirected action.
#RequestMapping(value="/getCodeAndProcess", method=RequestMethod.POST)
private ModelAndView getCodeAndProcess(#RequestParam("code") String code, HttpServletRequest request) throws Exception {
HttpSession session = null;
try {
session = request.getSession(false);
session.setMaxInactiveInterval(45*60);
String username = helper.processCodeAndGetUsername(code); //this is I'm getting using office 365.
String userRole = helper.getUserRoleBasedOnUsername(username);
System.out.println("================userRole================="+userRole);
if(username != "") {
session.setAttribute("username", username);
session.setAttribute("userRole", userRole);
}else {
session.invalidate();
throw new Exception("username not found");
}
return new ModelAndView("redirect:/adminDashboard/showDashboard");
}catch(Exception e) {
log.error("Error while processing on users authentication.",e );
session.invalidate();
return new ModelAndView("redirect:/login/loginPage");
}
}
Now, I don't get how to configure username and roles in security-context.xml, so that i can use #PreAuthorize("hasRole('ROLE_USER')") , isAuthenticated(), <sec:authorize in my application. (What to add in security-context.xml? So, that it bind username with role as it doing in form login scenario.)
Can you please help to understand this workflow?
I'm trying to secure my rest services written using dropwizard by Apache Shiro. First I initialized the security manager in the main method.
Factory<SecurityManager> factory = new IniSecurityManagerFactory("classpath:shiro.ini");
SecurityManager securityManager = factory.getInstance();
SecurityUtils.setSecurityManager(securityManager);
Then I wrote a service for user login.
if (!currentUser.isAuthenticated()) {
UsernamePasswordToken token = new UsernamePasswordToken(username, password);
token.setRememberMe(true);
try {
currentUser.login(token);
System.out.println("USER AUTHENTICATED!!!!!!!!");
} catch (Exception uae) {
System.out.println("Error logging in .................");
}
}
Then I declared a method with some java annotations.
#RequiresAuthentication
#RequiresRoles("admin")
#GET
#Path("/account")
#ApiOperation(value = "getAccount")
public void getAccount() {
//do something
}
But when I accessed this resource without logging in, I was successful.
What mistake am I doing? Or should I add something more? Like in the web.xml?
I found this repo very useful. https://github.com/silb/dropwizard-shiro/tree/release-0.2. I followed the instructions given in this. But there is one more thing I added in the configuration file.
#Valid
#JsonProperty("shiro-configuration")
public ShiroConfiguration shiro = new ShiroConfiguration();
Then in the resources class, I wrote login and logout as two services.
#POST
#Path("/session")
#Produces(MediaType.TEXT_PLAIN)
public String login(#FormParam("username") String username, #FormParam("password") String password, #Auth Subject subject) {
subject.login(new UsernamePasswordToken(username, password));
return username;
}
#PUT
#Path("/logout")
#Produces(MediaType.TEXT_PLAIN)
public String logout(#Auth Subject subject){
subject.logout();
return "Successfully logged out!";
}
And then I annotated the secured resources with #RequiresAuthentication annotation.
I am working on a Java desktop application and after some search I was able to authenticate the user using RestTemplate. Now the situation is I have the cookie String at the desktop side(code given below). Now what I would like to do is to do two important things, get which user logged in using that cookie and access(GET,POST,DELETE) secured resources which are marked with #Secured or #PreAuthorize annotation.
here is my authentication code :
#Override
public void initialize(URL location, ResourceBundle resources) {
submitButton.setOnAction(event -> {
if(!(usernameField.getText().isEmpty() && passwordField.getText().isEmpty())){
try {
RestTemplate rest = new RestTemplate();
String jsessionid = rest.execute("http://localhost:8080/j_spring_security_check", HttpMethod.POST,
new RequestCallback() {
#Override
public void doWithRequest(ClientHttpRequest request) throws IOException {
request.getBody().write(("j_username=" + usernameField.getText() + "&j_password=" + passwordField.getText()).getBytes());
}
}, new ResponseExtractor<String>() {
#Override
public String extractData(ClientHttpResponse response) throws IOException {
List<String> cookies = response.getHeaders().get("Cookie");
// assuming only one cookie with jsessionid as the only value
if (cookies == null) {
cookies = response.getHeaders().get("Set-Cookie");
}
String cookie = cookies.get(cookies.size() - 1);
System.out.println("Cookie is "+cookie);
int start = cookie.indexOf('=');
int end = cookie.indexOf(';');
return cookie.substring(start + 1, end);
}
});
// rest.put("http://localhost:8080/rest/program.json;jsessionid=" + jsessionid, new DAO("REST Test").asJSON());
} catch (AuthenticationException e) {
System.out.println("AuthenticationException");
}
} else {
System.out.println("Fields are empty");
}
});
}
Output of program is :
DEBUG: org.springframework.web.client.RestTemplate - Created POST request for "http://localhost:8080/j_spring_security_check"
DEBUG: org.springframework.web.client.RestTemplate - POST request for "http://localhost:8080/j_spring_security_check" resulted in 302 (Found)
Cookie is JSESSIONID=903B2924CCC84421931D52A4F0AA3C7E; Path=/; HttpOnly
If I was on server-side, I would have simply called the below method to get the currently authenticated user :
#Override
public Person getCurrentlyAuthenticatedUser() {
Authentication authentication = SecurityContextHolder.getContext().getAuthentication();
if (authentication == null) {
return null;
} else {
return personDAO.findPersonByUsername(authentication.getName());
}
}
How can I get the currently authenticate user on desktop based java app so I can just use below method and authenticate on desktop java app. :
Collection<GrantedAuthority> authorities = new ArrayList<>();
authorities.add(new SimpleGrantedAuthority("ROLE_USER"));
Authentication authentication = new UsernamePasswordAuthenticationToken(person1, null, authorities);
SecurityContextHolder.getContext().setAuthentication(authentication);
This way, I can use #Secured annotations for the desktop java app as well. Thanks a lot.
Update
So on the server side I have created a method which gives me the logged in user. As suggested in an answer, I can use the same rest template, but I would like to store the cookie in users local db instead of passing the Resttemplates object around when user clicks here and there.
Server side method :
#Secured("ROLE_USER")
#RequestMapping(value = "/rest/getloggedinuser", method = RequestMethod.GET)
public
#ResponseBody
ResponseEntity<RestPerson> getLoggedInRestUser() {
Person person = this.personService.getCurrentlyAuthenticatedUser();
RestPerson restPerson = new RestPerson();
restPerson.setFirstname(person.getFirstName());
restPerson.setUsername(person.getUsername());
restPerson.setPassword("PROTECTED");
return new ResponseEntity<RestPerson>(restPerson, HttpStatus.OK);
}
Now, next for now, I am trying to use the same RestTemplate to check if this method works with code below, but I would really like to know how I can do this with just a cookie :
HttpHeaders requestHeaders = new HttpHeaders();
requestHeaders.add("Cookie", cookie);
HttpEntity requestEntity = new HttpEntity(null, requestHeaders);
ResponseEntity rssResponse = rest.exchange(
"/rest/getloggedinuser",
HttpMethod.GET,
requestEntity,
Person.class);
String rssResponseBody = (String)rssResponse.getBody();
System.out.println("Response body is ");
Is there a way to cast the Object in the ResponseBody to the Person object???
If you want to get some user information which is stored on the server-side, you should create a new service, for example "getUserInformation" on your server, which will provide such information.
You should not extract cookies manually, just reuse the same RestTemplate, it stores cookies internally (specifically in the underlying HttpClient). That's how you can reach secure resources.
UPDATE:
You don't need to pass around the RestTemplate, just make it a singleton and use it everywhere.
And rssResponse.getBody(); should return you a Person object, not String.
I'm using this ContainerRequestFilter to check HTTP Basic credentials.
private class Filter implements ResourceFilter, ContainerRequestFilter {
#Override
public ContainerRequest filter(ContainerRequest request) {
String auth = request.getHeaderValue("Authorization");
if (auth == null || !auth.startsWith("Basic ")) {
throw new NotAuthorizedException("FAILED\n");
}
auth = Base64.base64Decode(auth.substring("Basic ".length()));
String[] vals = auth.split(":");
String username = vals[0];
String password = vals[1];
boolean validUser = database.Users.validate(username, password);
if (!validUser) {
throw new NotAuthorizedException("FAILED\n");
}
return request;
}
...
}
So by the time I get to this point, I've authenticated the user. Now how I can get the username?
#GET
#Path("some_kind_of_report_or_something")
#Produces(MediaType.TEXT_PLAIN)
public String fetchAReportOrSomething() {
// At this point, I know that the user has provided good credentials,
// now I need get the user's username as a String
String username = ???;
}
I suppose I could use HttpContext.getRequest() and do the same thing as in the AuthFilter (I'd move that username/password extraction logic to its own method). In the filter, can I somehow store the extracted username somewhere in the request object so it gets passed on to this handler?
(By the way, is there a better way to extract the username and password than what I've done in the filter? If so, let me know in a comment.)
This blog entry should enlighten you:
http://plaincode.blogspot.pt/2011/07/openid-authentication-example-in-jersey.html
Take a look how it's done in a working application: www.s3auth.com. The source code is available at github. As you can see on the site, facebook and google authentication mechanisms are used. The application is using JAX-RS/Jersey.
Please, at least pseudo (but from working environment not "maybe this should work") application context and controller/filter that will authenticate and/or auto-register Facebook users.
This link: http://blog.kadirpekel.com/2009/11/09/facebook-connect-integration-with-spring-security/ will not do. Actually I will put minus point to anyone who will post it as answer. I spend 2 hours with the thing and I didn't get it to work. I ended bit more bolder and feeling more stupid than usual after this endeavor :-(
I would really like to see OAuth 2.0 solution for facebook connect. And restrict the use of Facebook JavaScript API to absolute minimum.
Following link shows about what I need:
http://www.richardnichols.net/2010/06/implementing-facebook-oauth-2-0-authentication-in-java/
Please post only code to this question. I already got all the advice I can handle.
UPDATE
I have servlet solution and posted answer here if anyone is interested:

Here's an MVC implementation of facebook OAuth 2.0
The code's in C# and hopefully its similarity with java helps you out.
Controller(Entry point):Controller(in MVC) is the point in the code where the control reaches after someone clicks on the login link.
public ActionResult Authenticate()

var oauthFacebook = new FacebookOAuth();
if (Request["code"] == null)
{
//Redirect the user to Facebook for authorization.
Response.Redirect(oauthFacebook.AuthorizationLinkGet());
}
else
{
//Get the access token and secret.
oauthFacebook.AccessTokenGet(Request["code"]);
if (oauthFacebook.Token.Length > 0)
{
//We can now make our api calls
var user = oauthFacebook.GetAttributes();
}
}
}

I actually just finished my non-javascript, implementation of the Facebook Graph API Authentication last night. I was a gargantuan pain in the a**, but it works and it's working fairly well.
I used the example from the link you posted above as a starting point, as well as, the code from here as a starting point. I had to write my own implementation of their FacebookGraphAuthenticationProvider and their FacebookGraphAuthenticationFilter, but now it works the way I want it to.
You need to create implementations of both of these files, put your filter in the filter chain, and create a implementation of the Spring Security UserDetailsService that the Provider can use to manage your user account information. I have some code on my machine at home that I can send you via email if you like.
Here are the steps I had to use to get the authentication to work:
Get an "code" for a user, this is done by making the following call: https://www.facebook.com/dialog/oauth?client_id=YOUR_APP_ID&redirect_uri=YOUR_URL&scope=email,read_stream (The scope is all the permissions you want to request from FB). This call will create an "authentication code" which will then be sent back to your "redirect_uri" (which I stated as http://{my fb app registered domain}/j_spring_security_authentication_check.
Once you have this "code", you need to make a call within your AuthenticationProvider that will retrieve an access_token for your user's session: this URL looks like: https://graph.facebook.com/oauth/access_token? client_id=YOUR_APP_ID&redirect_uri=YOUR_URL&client_secret=YOUR_APP_SECRET&code=THE_CODE_FROM_ABOVE. You have to make sure your "redirect_uri" is the same as the one you did in #1. You'll make the above call using something like Apache's HttpClient, or the like.
Now with this access_token (which comes in the body of above response), you can get your user's profile information with the following URL: https://graph.facebook.com/me?access_token={ACCESS_TOKEN from above). The response will be in JSON. You can also use the access_token with all of the graph API to post status, pictures, etc.
I have some code at home that has my full implementation that I would be happy to share.
I hope this helps at least a bit. I suggest using the Spring Social app to get started with posting status, pictures, wall stuff, etc. This will be a good place to start looking at FB-Spring interaction.
