Spring Security，Rest Authentication和CSRF

Question

I would like use authentication with my application. I hava a Spring MVC app and Spring Security applied. Against browser, it is working fine. It means, I authenticate a user to my app and use web page.

Now, I want to use rest. I added on my unsecure controller method @ResponseBody and I receive response in json. But how to connect to my application with user and password with RestTemplate ?

My code in RestClient is (for test) :

public void unsecureProfileTest() {

    String url = articleServiceUrl + "unsecure/profile/test.json";
    url = articleServiceUrl + "secure/profile/wiew.json";
    HttpEntity<Object> entity = new HttpEntity<Object>(getHeaders("user:userpassword"));
    Object s = restTemplate.exchange(url, HttpMethod.GET, entity, Object.class);

}

static HttpHeaders getHeaders(String auth) {
    HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.APPLICATION_JSON);
    headers.setAccept(Arrays.asList(MediaType.APPLICATION_JSON,
            MediaType.TEXT_HTML));

    byte[] encodedAuthorisation = Base64.encode(auth.getBytes());
    headers.add("Authorization", "Basic "
            + new String(encodedAuthorisation));

    return headers;
}

My SecurityConfig :

@Override
protected void configure(HttpSecurity http) throws Exception {

    http.csrf().disable();

    http.authorizeRequests().antMatchers("/*").permitAll().and()
            .formLogin().successHandler(successHandler)
            .defaultSuccessUrl("/").failureHandler(failureHandler)
            .failureUrl("/login?error=true").permitAll().and().logout()
            .permitAll();

    http.authorizeRequests().antMatchers("/resources/**").permitAll();
    http.authorizeRequests().antMatchers("/welcome").permitAll();
    http.authorizeRequests().antMatchers("/unsecure/**").permitAll();

    http.authorizeRequests().antMatchers("/secure/*").authenticated();
    http.authorizeRequests().antMatchers("/admin/**").hasRole("ADMIN")
            .anyRequest().authenticated();
}

The result is : Access is denied. I guess the problem comming from authentication from restTemplate but how can I authenticate ?

My second question is regarding csrf who is disabled but I want to enable it (my forms use it)

I'm using Spring 4.0 and Spring Security 3.2

EDIT I updated my code with

String url = articleServiceUrl + "unsecure/profile/test.json";
url = articleServiceUrl + "secure/profile/wiew.json";
HttpEntity<Object> entity = new HttpEntity<Object>(getHeaders("{user:userpassword, password:userpassword}"));
Object s = restTemplate.exchange(url, HttpMethod.GET, entity, Object.class);

I receive a code 302

EDIT 18022014 - 16:46 I updated to

String url = articleServiceUrl + "login?username=user&password=userpassword";
HttpEntity entity restTemplate;exchange(url, HTTPMethod.POST,null, HttpEntity.class)
system.out.println(entity);

In log of web server, I received a success message (see userdetails on "user").

Now, I would like use authentication to access to other url ("secure/profile/view.json")

How to keep authentication ?

Thank you

I have been playing with spring security and spring boot REST application and I created my own MapCsrfTokenRepository that I used instead of default HttpSessionCsrfTokenRepository .

Then you can enable csrf for your rest URIs with

http.csrf().csrfTokenRepository(tokenRepository)

The main idea is to return new CSRF_TOKEN when client access /login resource with GET , because no csrf token is needed for GET. And then client has to use this token in next calls.

Example is on github
