Changing the login service URL in spring security

Question

Hi I have implemented Spring security in my spring boot web application with JWT filters. But the default authentication is happening at url http://localhost:8080/login . How to change /login to some url I need like /rest/auth/login?

My WebSecurity class is

@EnableWebSecurity
public class WebSecurity extends WebSecurityConfigurerAdapter {

@Autowired
private UserDetailsService userDetailsService;

@Autowired
private BCryptPasswordEncoder bCryptPasswordEncoder;

public WebSecurity( UserDetailsService userDetailsService, BCryptPasswordEncoder bCryptPasswordEncoder )
{
    this.userDetailsService = userDetailsService;
    this.bCryptPasswordEncoder = bCryptPasswordEncoder;
}

@Override
protected void configure( HttpSecurity http ) throws Exception
{
    http.cors().and().csrf().disable().authorizeRequests().antMatchers(HttpMethod.POST, "/rest/auth/**").permitAll()
            .antMatchers("/static/*").permitAll().antMatchers("/").permitAll()
            /* .anyRequest().authenticated() */.and()
            .addFilter(new JWTAuthenticationFilter(authenticationManager()))
            .addFilter(new JWTAuthorizationFilter(authenticationManager()));
}

@Override
public void configure( AuthenticationManagerBuilder auth ) throws Exception
{
    auth.userDetailsService(userDetailsService).passwordEncoder(bCryptPasswordEncoder);
}

@Override
public void configure( org.springframework.security.config.annotation.web.builders.WebSecurity web )
        throws Exception
{

    web.ignoring().antMatchers("/static/**");
}

@Bean
CorsConfigurationSource corsConfigurationSource()
{
    final UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
    source.registerCorsConfiguration("/**", new CorsConfiguration().applyPermitDefaultValues());
    return source;
}
}

I have a login page in my resource folder under static directory. The way Spring security works is, when user sends userName and password from the form, client has to send those credentials to /login path in the server, so that spring security verifies those credentials and creates token. But I want to change that default path /login to /rest/auth/login

In your AuthenticationFilter you can call setFilterProcessesUrl during construction, example:

public class JWTAuthenticationFilter extends UsernamePasswordAuthenticationFilter {

   private AuthenticationManager authenticationManager;

   public JWTAuthenticationFilter(AuthenticationManager authenticationManager) {
      this.authenticationManager = authenticationManager;

      setFilterProcessesUrl("/api/v1/tokens"); // <--- like this
   }

   ...

Hope it helps.
