I am new with RESTful web services in spring,whenever i am requesting the URL through postman,i am getting random generated token from server side, here you are controller code,through this i am getting random generated token.
#RequestMapping(value = "/api/authenticate", method = RequestMethod.POST)
public #ResponseBody
Result doLogIn(#RequestParam("BulkData") String bulkData, HttpServletResponse response) throws Exception {
ObjectMapper mapper = new ObjectMapper();
JsonNode actualObj = null;
try {
actualObj = mapper.readTree(bulkData);
} catch (IOException e1) {
e1.printStackTrace();
return new Result("Invalid Request", ResultCodes.LOGIN_FAILURE);
}
String userName = actualObj.get("userName").asText();
String password = actualObj.get("password").asText();
logger.debug("[REST]: Attempting login for -> " + userName);
UserDetails details = userDetailService.loadUserByUsername(userName);
// validate password
if (details != null && !details.getPassword().equals(password)) {
logger.debug("[REST]: Invalid username/password");
try {
response.sendError(HttpServletResponse.SC_UNAUTHORIZED, "Invalid username/password");
} catch (IOException e) {
e.printStackTrace();
}
return new Result("Invalid username or password", ResultCodes.LOGIN_FAILURE);
}
// Generate token. ATM, use only username
String generatedToken = Jwts.builder().setSubject(userName)
.setIssuedAt(new Date())
// set token expiration time
.setExpiration(new Date(System.currentTimeMillis() + Config.TOKEN_EXPIRY_PERIOD))
.signWith(SignatureAlgorithm.HS256, servletContext.getInitParameter("API_SECRET_KEY"))
.compact();
// provide token to user in form of a Http Header
response.addHeader(Config.AUTH_TOKEN_HEADER_NAME, generatedToken);
return new Result("Login Success", ResultCodes.LOGIN_SUCCESS_TOKEN_GENERATED);
}
and here is the code for authorization , to do so i am using AuthenticationTokenProcessingFilter,
public class AuthenticationTokenProcessingFilter extends GenericFilterBean {
#Autowired
private UserDetailService userDetailService;
#Autowired
private AuthenticationManager authenticationManager;
private static Logger logger = Logger.getLogger(AuthenticationTokenProcessingFilter.class);
#Override
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
throws IOException, ServletException {
HttpServletRequest req = (HttpServletRequest) request;
// Exclude login URL
if(req.getRequestURI().endsWith("/api/authenticate")) {
chain.doFilter(req, response);
return;
}
// Client must send token in header
String authHeader = req.getHeader(Config.AUTH_TOKEN_HEADER_NAME);
if (authHeader == null) {
logger.error("[REST]: Authentication header was null...");
throw new ServletException("Missing or invalid Authorization header.");
}
// Parse token, fetch user and reload Security Context
try {
String SECRET_KEY = getServletContext().getInitParameter("API_SECRET_KEY");
Jws<Claims> claims = Jwts.parser().setSigningKey(SECRET_KEY).parseClaimsJws(authHeader);
Claims claim = claims.getBody();
String userName = claim.getSubject();
logger.debug("[REST]: Token of user -> " + userName + " expires: " + claim.getExpiration());
UsernamePasswordAuthenticationToken token = new UsernamePasswordAuthenticationToken(userName, userDetailService.loadUserByUsername(userName).getPassword());
token.setDetails(new WebAuthenticationDetails(req));
Authentication authentication = authenticationManager.authenticate(token);
SecurityContextHolder.getContext().setAuthentication(authentication);
} catch (SignatureException e) {
logger.debug("[REST]: Invalid token");
throw new ServletException("Invalid token.");
}
chain.doFilter(req, response);
// clear security context now because we are going for Stateless Web Services
SecurityContextHolder.getContext().setAuthentication(null);
}
now i want to use this generated token to call this method ,
#RequestMapping(value="/api/admin/getEmployeerole", method=RequestMethod.POST)
public List<EmployeeRole> EmployeeRoleList() {
List<EmployeeRole> getRole=employeeRoleService.getAll();
return getRole;
}
now what is happening here when i am writing this URL to postman and adding generated token into header ,and i have used authorization type (No auth), i have also tried with basic Authorization, still my request is going to customAuthenticationEntrypoint and it throws Access denied exception,that the user Role is annonymous, at server side i am getting status 401 unauthorized.it would be great if someone can help to get over from this..
here You are my spring security configuration..

I have a problem. Suppose I login into the application and accessing different pages and leaving the application ideal for 5 min in http://localhost:8080/InformationManagement/smartapp/allFileNetStatus and then trying to access once the session get expired and get redirected to login page.
Once I enter the credentials it get logged in it get me to http://localhost:8080/InformationManagement/smartapp/allFileNetStatus instead of home page(http://localhost:8080/InformationManagement/)
Note: My Login page and Home page URL is same
How can I control this in spring security.
Code:
<http pattern="/resources" security="none" />
<http auto-config="true" use-expressions="true">
<intercept-url pattern="/login" access="permitAll" />
<intercept-url pattern="/logout" access="permitAll" />

You should implement your own AuthenticationSuccessHandler for that.
<!-- Add to your form login the handler-->
<form-login login-page="/login" authentication-failure-url="/login/failure"
default-target-url="/" authentication-success-handler-ref="homeRedirectSuccessHandler" />
<beans:bean id="homeRedirectSuccessHandler"
class="your.package.HomeRedirectSuccessHandler" />
And in your HomeRedirectSuccessHandler:
protected void handle(HttpServletRequest request,
HttpServletResponse response, Authentication authentication) throws IOException {
redirectStrategy.sendRedirect(request, response, "yourHomepage.html);
}
My web application uses spring security to authenticate user on login. I also have concurrency control to avoid user to login twice on different machine. This is working fine but my problem is that:
If user is login on a machine, then close the browser. And he reopen the web app , try to login again he gets the following msg 'Maximum sessions of 1 for this principal exceeded' . I want to invalidate the session on browser closed. How can I do this?

Use this filter How to get session time out message using Spring security
I am using java config for spring security and I am trying to replace this code with no luck
<security:custom-filter ref="authenticationTokenProcessingFilter" position="FORM_LOGIN_FILTER" />
cant find any info about how to use the position in java config
Update i am trying to replace this code by java config but with no luck
<security:http

and this is my AuthenticationTokenProcessingFilter
public class AuthenticationTokenProcessingFilter extends UsernamePasswordAuthenticationFilter

private final UserDetailsService userService;
public AuthenticationTokenProcessingFilter(UserDetailsService userService)
{
this.userService = userService;
}
#Override
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException,

String authToken = this.extractAuthTokenFromRequest(httpRequest);
String userName = TokenUtils.getUserNameFromToken(authToken);
if (userName != null) {
UserDetails userDetails = this.userService.loadUserByUsername(userName);
if (TokenUtils.validateToken(authToken, userDetails)) {
UsernamePasswordAuthenticationToken authentication =
new UsernamePasswordAuthenticationToken(userDetails, null, userDetails.getAuthorities());
authentication.setDetails(new WebAuthenticationDetailsSource().buildDetails(httpRequest));
SecurityContextHolder.getContext().setAuthentication(authentication);
}
}
chain.doFilter(request, response);
}
private HttpServletRequest getAsHttpRequest(ServletRequest request)
{
if (!(request instanceof HttpServletRequest)) {
throw new RuntimeException("Expecting an HTTP request");
}
return (HttpServletRequest) request;
}
private String extractAuthTokenFromRequest(HttpServletRequest httpRequest)
{
/* Get token from header */
String authToken = httpRequest.getHeader("X-Auth-Token");
/* If token not found get it from request parameter */
if (authToken == null) {
authToken = httpRequest.getParameter("token");
}
return authToken;
}
Hope this is clearer
Here are the filter classes in the order of execution and with the addFilter method of the HttpSecurity class you add your own filters:
#Override
public void configure(HttpSecurity http) throws Exception {
http.addFilter(new AuthenticationTokenProcessingFilter());
...
You have to either extend or provide an instance of the defined Spring filters. The order is based on the class or superclass so you don't have to add the position:

I've changed the default Authentication Provider for a Custom one.
This is my AuthenticationProvider
public class CustomAuthenticationProvider implements AuthenticationProvider {
#Autowired
private ParamsProperties paramsProperties;
#SuppressWarnings("unchecked")
public Authentication authenticate(Authentication authentication) throws AuthenticationException {
//Check username and passwd
String user = (String) authentication.getPrincipal();
String pass = (String) authentication.getCredentials();
if(StringUtils.isBlank(user) || StringUtils.isBlank(pass) ){
throw new BadCredentialsException("Incorrect username/password");
}
//Create SSO
SingleSignOnService service = new SingleSignOnService(paramsProperties.getServicesServer());
try {
//Check logged
service.setUsername(authentication.getName());
service.setPassword(authentication.getCredentials().toString());
ClientResponse response = service.call();
String result = response.getEntity(String.class);
ObjectMapper mapper = new ObjectMapper();
Map<String,Object> map = mapper.readValue(result, new TypeReference<Map<String,Object>>() {} );
//Read code
String code = (String)map.get("code");
log.debug(" ** [Authenticate] Result: " + code );
for (String s : (List<String>)map.get( "messages" ) ) {
log.debug(" [Authenticate] Message: " + s );
}
if ( code.equals( "SESSION_CREATED" ) || code.equals( "SESSION_UPDATED" ) || code.equals( "SESSION_VERIFIED" ) ) {
UsernamePasswordAuthenticationToken tokenSSO = LoginHelper.getuserSringTokenFromAuthService(map);
return tokenSSO;
} else {
return null;
}
} catch (Exception e) {
e.printStackTrace();
throw new AuthenticationServiceException( e.getMessage() );
}
}
public boolean supports(Class authentication) {
return authentication.equals(UsernamePasswordAuthenticationToken.class);
}
And this is my security.xml
<http>
<form-login default-target-url ="/Login.html" always-use-default-target="true" login-page="/Login.html" login-processing-url="/j_spring_security_check"
authentication-failure-url="/Login.html" />
<http-basic />
<logout logout-success-url="/Login.html" />
</http>
<beans:bean id="localeFilter" class="com.mycomp.comunes.server.spring.controller.login.MyLocaleFilter" lazy-init="true">
<custom-filter position="LAST"/>
</beans:bean>
<beans:bean id="authenticationProvider" class="com.indra.rfef.comunes.server.spring.manager.autenticacion.CustomAuthenticationProvider">
<custom-authentication-provider />
</beans:bean>
It gets over my CustomAuthenticationProvider, and authenticates correctly the user. But when returning tokenSSO, of type UsernamePasswordAuthenticationToken, it seems it's not saving the user on the Security Context, and when I redirect the user (on the callback of the authenticate) to the index.html, I get redirected back to Login.html.
Why could this happen? I'm I forgetting something?
Please fix your configuration:
<http>
<intercept-url pattern="/Login*" access="IS_AUTHENTICATED_ANONYMOUSLY"/>
<intercept-url pattern="/**" access="ROLE_USER"/>
<form-login login-page="/Login.html" login-processing-url="/j_spring_security_check" authentication-failure-url="/Login.html" />
<http-basic />
<logout logout-success-url="/Login.html" />
</http>
Remove default-target-url ="/Login.html". It makes the redirection after login to the same login page. The default is /.
Add security on all URLs <intercept-url pattern="/**" access="ROLE_USER"/>
Do not remove the anonymous access from the login page
Why you need BasicAuthentication? Remove it if not required: <http-basic />
I want to write my own LDAP authentication provider. I am extending AbstractUserDetailsAuthenticationProvider, which has a method retrieveUser(String username, UsernamePasswordAuthenticationToken authentication).
I want to override this method and write my own data retrieving method. How to do that in Java? How to make an LDAP query and how connect to the LDAP server? I was searching in Internet but I didn't find anything that helped.
EDIT: 22.01.2013
#Override
protected UserDetails retrieveUser(String username,
UsernamePasswordAuthenticationToken authentication)
throws AuthenticationException {
LdapUser userDetail = null;
log.entry("retrieveUser", authentication.getPrincipal());
UsernamePasswordAuthenticationToken userToken = authentication;
String userName = userToken.getName();
userName = userName != null ? userName.toLowerCase() : userName;
String password = userToken.getCredentials().toString();
try {
if (password == null || "".equals(password)) {
log.debug("retrieveUser", "no password provided");
throw new AuthenticationCredentialsNotFoundException(
"Invalid login or password");
}
}
catch (AuthenticationCredentialsNotFoundException e) {
log.debug("retrieveUser", "no password provided");
}
// connection with ldap and check retrieved username and password
connect = connection(userName, password);
if (connect) {
log.debug("retrieve user", "correct connection with ldap");
userDetail = new LdapUser();
setUserDetails(userDetail, ctx, username);
} else {
log.error("retrieve user", "Failed connection");
}

return userDetail;

You can connect to LDAP from java:
http://docs.oracle.com/javase/jndi/tutorial/ldap/security/ldap.html
but spring security already has ldap integration, you can use of the methods described here:
http://static.springsource.org/spring-security/site/docs/3.0.x/reference/ldap.html
