    <div class="form-group input-login">
        <div ng-if="message.error" class="alert alert-danger">
            <p>Invalid username and password.</p>
        </div>
        <div ng-if="message.logout" class="alert alert-success">

    <input name="_csrf" type="hidden" value="6829b1ae-0a14-4920-aac4-5abbd7eeb9ee" /> 
    <div class="form-group sub-login">
        <div class=" col-md-12">
            <button name="submit" type="submit" class="btn btn-primary btn-login">Login</button>
        </div>
    </div>
</form>

Pero si no desactivo elcsrfsiempre seráaccessDeniedNo sé dónde está el problema.

Mi código de configuración a continuación.

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    private UserDao userDao;

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {

        auth.userDetailsService(new UserService(userDao)).passwordEncoder(new MD5Util());
    }

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

        http.authorizeRequests()
                .antMatchers("/", "/index").access("hasRole('USER')")
                .and()
                    .formLogin()
                    .loginPage("/login")
                    .failureUrl("/login#/signin?error=1")
                    .successHandler(new LoginSuccessHandler())
                    .usernameParameter("username").passwordParameter("password")
                .and()
                    .logout()
                    .logoutUrl("/logout")
                    .logoutSuccessUrl("/login#/signin?logout=1")
                .and()
                    .exceptionHandling().accessDeniedPage("/Access_Denied")
                .and().csrf().disable(); // If I  disable this csrf,it worked!

    }
}
