IllegalStateException after trying to access a specific URL with AbstractPreAuthenticatedProcessingFilter implementation

We have extended AbstractPreAuthenticatedProcessingFilter to authenticate shibboleth users, it does nothing special but obtain the user name from a specific request attribute and return a PreAuthenticatedAuthenticationToken.
If we access the root context of our application it works ok, but if we request a specific URL within our application we get "java.lang.IllegalStateException: Response already commited".
In SecurityConfig we have:
#Override
protected void configure(final HttpSecurity http) throws SecurityException {
try {
http.authorizeRequests().antMatchers("/favicon.ico", "/resources/**", "/signin**").permitAll()
.anyRequest().authenticated().and().formLogin().loginPage("/signin").permitAll()
.failureUrl("/signin?error=1").successHandler(new CustomAuthenticationSuccessHandler())
.loginProcessingUrl("/authenticate").and().sessionManagement().invalidSessionUrl("/signin")
.and().exceptionHandling().accessDeniedHandler(new AccessDeniedHandler()).and().headers()
.frameOptions().disable();
http.addFilterBefore(
new ShibbolethPreAuthenticatedProcessingFilter(new ShibbolethAuthenticationManager(),
new CustomAuthenticationSuccessHandler()),
AbstractPreAuthenticatedProcessingFilter.class);
http.logout().logoutUrl("/logout")
.logoutSuccessUrl(environment.getProperty(Constantes.CT_SHIBBOLETH_LOGOUT_URL))
.clearAuthentication(true).invalidateHttpSession(true);
} catch (final Exception e) {
throw new SecurityException(e);
}
}
ShibbolethAuthenticationManager implements AuthenticationManager and just loads UserDetails and GrantedAuthorities into a PreAuthenticatedAuthenticationToken
CustomAuthenticationSuccessHandler extends SavedRequestAwareAuthenticationSuccessHandler and loads the user language into the LocaleProvider and loads the current license details into the session.
If we request for "/" in our application it takes us to:
#ResponseStatus(HttpStatus.MOVED_PERMANENTLY)
#RequestMapping("/")
public String index(HttpServletRequest httpRequest, HttpSession session, Authentication auth) {
if (auth.getAuthorities().contains(new SimpleGrantedAuthority(Constants.CONTROL_PANEL_PERMISSION))) {
return "redirect:/controlpanel/dashboard";
} else if (auth.getAuthorities().contains(new SimpleGrantedAuthority(Constants.CONFIG_PERMISSION)))
{
return "redirect:/config";
} else {
return "redirect:/userpage";
}
}
I don't know why those redirects work, but not when we request another URL, for example if we request to go directly to /controlpanel/dashboard we get the error.
#RequestMapping("/controlpanel/dashboard")
public String dashboard(Model model, HttpServletRequest httpRequest, HttpSession session,
#RequestParam(name = "comite", defaultValue = "-1") Long comite,
#RequestParam(required = false) final Boolean tasksToDo) {
// This method does nothing but add things to the model object, such as:
model.addAttribute("tasks", tasksToDo);
// and then it takes the user to the view page
return "cuadromando/dashboard";
}

In the end I solved it by implementing AuthenticationSuccessHandler instead of extending SavedRequestAwareAuthenticationSuccessHandler:
CustomSuccessHandler implements AuthenticationSuccessHandler
So I get rid of the commited response, because both SavedRequestAwareAuthenticationSuccessHandler and SimpleUrlAuthenticationSuccessHandler called getRedirectStrategy().sendRedirect(request, response, targetUrl); so they commited the response before we could do the actual redirect we needed.

Spring boot with spring session and security. RMI fails with 401

I'm using Spring boot with spring security and Spring Session with redis for authentication and authorization. There are two separate projects running and I want to connect them with RMI tunneled over HTTP.
Even though I've used setRemoteInvocationFactory in HttpInvokerProxyFactoryBean Since the 2nd service throws 401. I'm getting Internal server error. What's the workaround?
I'm passing session id in the header as x-auth-token. Should I pass the same through service invoker?
Here is the code
Exporter:
#Configuration
#EnableAutoConfiguration
public class ServiceExporter {
#Bean(name = "/rmi")
HttpInvokerServiceExporter accountService(#Autowired rmiimpl rmi) {
HttpInvokerServiceExporter exporter = new HttpInvokerServiceExporter();
exporter.setServiceInterface(rmiinterface.class);
exporter.setService(rmi);
return exporter;
}
}
Invoker:
#Configuration
#EnableAutoConfiguration
public class test {
#Bean
public HttpInvokerProxyFactoryBean invoker() {
HttpInvokerProxyFactoryBean invoker = new HttpInvokerProxyFactoryBean();
String serviceURL = "http://localhost:8081/rmi";
invoker.setServiceUrl(serviceURL);
invoker.setServiceInterface(rmiinterface.class);
invoker.setRemoteInvocationFactory(remoteinvocation());
return invoker;
}
#Bean
RemoteInvocationFactory remoteinvocation() {
return new ContextPropagatingRemoteInvocationFactory();
}
}
SecurityConfig:
#Configuration
#EnableWebSecurity
public class SessionSecurityConfig extends WebSecurityConfigurerAdapter {
#Bean
public HttpSessionStrategy httpSessionStrategy() {
return new HeaderHttpSessionStrategy();
}
#Override
protected void configure(final AuthenticationManagerBuilder auth) throws Exception {
auth.inMemoryAuthentication().withUser("admin").password("adminPass").roles("ADMIN");
}
#Override
protected void configure(HttpSecurity http) throws Exception {
// https://www.baeldung.com/spring-security-session
http.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.IF_REQUIRED);
http.csrf().disable().authorizeRequests() //
.antMatchers("/auth/*").fullyAuthenticated() //
.and().requestCache() //
.requestCache(new NullRequestCache()) //
.and().httpBasic();
}
}
Exception:
java.io.IOException: Did not receive successful HTTP response: status code = 401, status message = [null]

Not sure what's missing.

Finally Figured out.
AS we all know that Spring Security reads Session Id from cookie by default. In this case, since I've used #Bean public HttpSessionStrategy it reads from header x-auth-token.
Whenever HttpInvokerProxyFactoryBean tries to connect the authentication context is propagated but since it's an HTTP call the default spring session filter tries reading the session ID and validate the same. Since here session Id is not transmitted it throws 401.
In order to fix it. I need to set the header in HTTP invoker. The same applies if cookie is used. Since HttpInvokerProxyFactoryBean uses SimpleHttpInvokerRequestExecutor. I created a new class by extending it and added the header by overriding prepareConnection. I used setHttpInvokerRequestExecutor in invoker to set the executor to call the new class.
Here is the code.
Invoker:
#Configuration
#EnableAutoConfiguration
public class test {
#Bean
public HttpInvokerProxyFactoryBean invoker() {
HttpInvokerProxyFactoryBean invoker = new HttpInvokerProxyFactoryBean();
String serviceURL = "http://localhost:8081/rmi";
invoker.setServiceUrl(serviceURL);
invoker.setServiceInterface(rmiinterface.class);
invoker.setHttpInvokerRequestExecutor(httpInvokerRequestExecutor()); //call to the bean
return invoker;
}
#Bean
public SimpleHttpInvokerRequestExecutor httpInvokerRequestExecutor() {
return new CustomHttpInvokerRequestExecutor();
}
}
class CustomHttpInvokerRequestExecutor extends SimpleHttpInvokerRequestExecutor {
#Autowired
HttpSession session;
#Override
protected void prepareConnection(HttpURLConnection connection, int contentLength) throws IOException {
// adding header.
connection.addRequestProperty("x-auth-token", session.getId());
super.prepareConnection(connection, contentLength);
}
}
Now it started working.

MethodArgumentTypeMismatchException: How to find the controller method

I am finding below error happening in my log file, but this error message does not provide enough details to about the controller method which is causing this error. I have a lot of controllers in the application and thus it is difficult to say which method is responsible for the error. Could anybody advise me how I could improve logs to get more details about which controller method is throwing this error

Option 1
Set debug logging level for org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping
and carefully watch the log file.
You should see something like:
s.w.s.m.m.a.RequestMappingHandlerMapping : Looking up handler method for path /mypath
s.w.s.m.m.a.RequestMappingHandlerMapping : Returning handler method [public java.util.Map<java.lang.String, java.lang.Object> com.my.something.web.MyController.myHandlerMethod(long)]
before the exception stack trace.
Option 2
Catch the exception using HandlerExceptionResolver:
Firstly we need to implement HandlerExceptionResolver:
#Slf4j
public class MethodArgumentTypeMismatchExceptionLoggingExceptionHandler implements HandlerExceptionResolver {
#Override
public ModelAndView resolveException(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) {
if (ex instanceof MethodArgumentTypeMismatchException) {
MethodArgumentTypeMismatchException e = (MethodArgumentTypeMismatchException)ex;
// Do anything you want with it.
// The method can be accessed using e.getParameter().getExecutable()
log.error("Caught MethodArgumentTypeMismatchException method = {}",
e.getParameter().getExecutable(), e);
}
return null;
}
}
and the register it in some kind of MvcConfig:
#Configuration
#Slf4j
public class MvcConfig implements WebMvcConfigurer {
#Override
public void extendHandlerExceptionResolvers(List<HandlerExceptionResolver> resolvers) {
resolvers.add(0, new MethodArgumentTypeMismatchExceptionLoggingExceptionHandler());
}
}

Cannot call sendError() after the response has been committed - Using Keycloak with spring Security + Boot

I Have a spring Boot application which is using spring security and Keycloak for idnetity/access management. When testing keycloak locally everything seems fine but when i am now using the keycloak online i am getting the error Cannot call sendError() after the response has been committed after the user logs in
These are thge Keycload setting within the Spring Boot Application properties file
keycloak.auth-server-url=
keycloak.ssl-required=external
keycloak.realm=
keycloak.resource=
keycloak.enabled=true
keycloak.credentials.secret=
keycloak.principal-attribute=preferred_username
Spring Security Config
#Configuration
#EnableWebSecurity
#ComponentScan(basePackageClasses = KeycloakSecurityComponents.class)
class SecurityConfig extends KeycloakWebSecurityConfigurerAdapter {
// Submits the KeycloakAuthenticationProvider to the AuthenticationManager
#Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
KeycloakAuthenticationProvider keycloakAuthenticationProvider = keycloakAuthenticationProvider();
keycloakAuthenticationProvider.setGrantedAuthoritiesMapper(new SimpleAuthorityMapper());
auth.authenticationProvider(keycloakAuthenticationProvider);
}
#Bean
public KeycloakSpringBootConfigResolver KeycloakConfigResolver() {
return new KeycloakSpringBootConfigResolver();
}
#Bean
#Override
protected SessionAuthenticationStrategy sessionAuthenticationStrategy() {
return new RegisterSessionAuthenticationStrategy(new SessionRegistryImpl());
}
#Override
protected void configure(HttpSecurity http) throws Exception {
super.configure(http);
http.authorizeRequests()
.antMatchers("/customers*")
.hasRole("myrole")
.anyRequest()
.permitAll();
}
}
This is the complete error I'm getting in spring boot. Unfortunatley i do not have access to keycloak's

Here is request mapping, which is used when I try to find some contact in select2..
#RequestMapping(method = GET)
#ResponseBody
public List<Object> findIt(#RequestParam(name = "query", defaultValue = "") String query) {
Map<GroupKey, List<Contact>> groupedContacts = contactRepository.findItByQuery(query)
.stream()
.collect(groupingBy(contact -> new GroupKey(contact)));
return groupedContacts.entrySet()
.stream()
.map(entry -> {
GroupKey key = entry.getKey();
List<Contact> contacts = entry.getValue();
if (contacts.size() == 1) {
return contacts.get(0);
} else {
return new Group(key.toString(), contacts);
}
})
.collect(toList());
}
During the investigation I wasn't able to find answers to my questions. What is Region of Resource: Region of a Resource implementation, materialized by a position within the Resource and a byte count for the length of that region. .
Question 0: Why do I need cast from Contact to ResourceGroup?
Question 1: Why is this casting does not work now?
Before you down vote this question, just please tell me why. Thank you!

This happens because your application fails to find a valid HttpMessageConverter to convert your objects to JSON and defaults to ResourceRegion converter (which is default to octet stream response)
Try to do this:
#Configuration
#EnableWebMvc
public class WebServicesConfig implements WebMvcConfigurer {
#Override
public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
MappingJackson2HttpMessageConverter jsonConverter = new MappingJackson2HttpMessageConverter();
jsonConverter.setSupportedMediaTypes(Collections.singletonList(MediaType.APPLICATION_JSON));
converters.add(jsonConverter);
}
}
