spring boot security allow post request but only with permission - spring-boot

So my problem is a little different from the rest of the spring boot questions. I want to allow post requests in my security config but only with authentication
here is my config file:
#Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests()
.anyRequest().authenticated()
.and()
.httpBasic();
http.csrf().disable();
}
thanks for helping ;)

You can use antMachers with the following pattern.
antMatchers(HttpMethod.POST)
if you want to authenticate POST method of only certainpath
antMatchers(HttpMethod.POST, "/path")

Spring Security: don't redirect to login page in case unauthorised

I have Spring Security with oAuth2 authorisation.
I use it for REST API.
My configuration:
#Configuration
#EnableWebSecurity
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {
#Override
protected void configure(HttpSecurity httpSecurity) throws Exception {
httpSecurity
.csrf().disable()
.authorizeRequests()
.antMatchers("/health").permitAll()
.antMatchers("/**").authenticated()
.and()
.oauth2Login()
.and()
.httpBasic();
}
}
I need to make all requests return me 401 when I didn't authorise.
But now when I'm not authorised I got redirect to /login page.
I need to use it like usual REST API: if I did authorise then get content, otherwise get 401 Unauthorised.
How I can make it?
Thanks in addition for help.
Basically you need to configure an AuthenticationEntryPoint which is invoked when Spring Security detects a non-authenticated request. Spring also gives you a handy implementation which enables you to return whatever HttpStatus you need:
#Override
protected void configure(HttpSecurity httpSecurity) throws Exception {
httpSecurity
//rest of your config...
.exceptionHandling()
.authenticationEntryPoint(new HttpStatusEntryPoint(HttpStatus.UNAUTHORIZED));
}

Oauth2 security configuration antmatchers request filtering not working as expected

I am working on a simple spring boot project along with spring security oauth2 to use google authentication for a specified endpoint which is /google/login.
With following security configurations everything is working perfectly.
#Configuration
public class SecurityConfigure extends WebSecurityConfigurerAdapter {
#Override
public void configure(HttpSecurity http) throws Exception {
http
.requestMatchers().antMatchers("/**")
.and()
.authorizeRequests().antMatchers("/ldap/login").permitAll()
.anyRequest().fullyAuthenticated()
.and()
.oauth2Login();
}
}
But I need to specify only /google/login endpoint to authenticate with oauth2. Therefore I specified it like this.
#Configuration
public class SecurityConfigure extends WebSecurityConfigurerAdapter {
#Override
public void configure(HttpSecurity http) throws Exception {
http
.requestMatchers().antMatchers("/google/**")
.and()
.authorizeRequests().antMatchers("/ldap/**").permitAll()
.anyRequest().fullyAuthenticated()
.and()
.oauth2Login();
}
}
with this security configuration http://localhost:8080/google/login endpoint call redirects to another endpoint called http://localhost:8081/oauth2/authorization/google which is I haven't defined.
Please help me to overcome this problem. Thank you.
This configuration works for me. I had to allow all endpoints that were redirecting while Google's authentication process was running. 
#Override
protected void configure(HttpSecurity http) throws Exception {
http
.csrf().disable()
.requestMatchers().antMatchers("/google/**","/oauth2/authorization/google","/login/oauth2/code/google")
.and()
.authorizeRequests().antMatchers("/ldap/**").permitAll()
.anyRequest().fullyAuthenticated()
.and()
.oauth2Login();
}

Spring Boot Security - Multiple configurations

I'm working (and struggling a little bit) on an example using spring-boot with spring security.
My system is using a web app and also provide an REST-API, so i would like to have form based security (web) and basic auth (resp api).
As the spring documentation recommend (https://docs.spring.io/spring-security/site/docs/current/reference/htmlsingle/#multiple-httpsecurity), I need to create a multi http web security configuration.
The main code works, but if I use Postman for the test of my RestApi following use-case does not work.
All GET-requests to /restapi/ working without authentication (statuscode 200)
All POST-requests to /restapi/ without the BASIC Auth Header are working (statuscode 401)
All POST-requests to /restapi/ with a correct BASIC Auth Header are work (statuscode 200)
BUT all requests with a wrong BASIC Auth header (f.e. user1/1234567) are returning the HTML-Loginpage defined in the first WebSecurityConfigurerAdapter (FormWebSecurityConfigurerAdapter)
Does anyone has an idea - what is wrong with my configuration?
#EnableWebSecurity
public class MultiHttpSecurityConfig {
#Autowired
private static RestAuthenticationAccessDeniedHandler restAccessDeniedHandler;
#Autowired
public void configureAuth(AuthenticationManagerBuilder auth) throws Exception{
auth.inMemoryAuthentication()
.withUser("admin").password("{noop}12345678").roles("ADMIN").and()
.withUser("user").password("{noop}12345678").roles("USER");
}
#Configuration
#Order(1)
public static class RestWebSecurityConfigurationAdapter extends WebSecurityConfigurerAdapter {
protected void configure(HttpSecurity http) throws Exception {
http
.antMatcher("/restapi/**")
.authorizeRequests()
.antMatchers(HttpMethod.GET, "/restapi/**").permitAll()
.and()
.authorizeRequests().anyRequest().authenticated()
.and()
.httpBasic()
.and()
.csrf().disable()
.exceptionHandling().authenticationEntryPoint(new HttpStatusEntryPoint(UNAUTHORIZED))
.and()
.exceptionHandling().accessDeniedHandler(restAccessDeniedHandler) ;
}
}

*/
#Configuration
public static class FormWebSecurityConfigurerAdapter extends WebSecurityConfigurerAdapter {
#Override
protected void configure(HttpSecurity http) throws Exception {
http
.authorizeRequests()
.antMatchers("/css/**", "/img/**", "/js/**", "/index.html", "/").permitAll()
.and()
.authorizeRequests().anyRequest().authenticated()
.and()
.formLogin()
.loginPage("/login")
.permitAll()
.and()
.logout()
.logoutUrl("/logout")
.logoutSuccessUrl("/index.html")
.permitAll();
}
}
}
I know it is a question from some time ago but I still want to share the answer for people who are struggling with this issue.
After a lot of searching I found out that the /error endpoint in spring boot 2.x is now secured by default. What I mean to say is in the past the /error was a endpoint what had no security at all (or didn't exist). The solution to this issue is quite straight forward.
antMatchers('/error').permitAll()
within your web security adapter configuration(s).
What happens if you don't do this, the security will check the endpoint against your configuration and if it cannot find this endpoint (/error) it will redirect to the standard login form, hence the 302.

Spring Security Unexpected Behaviour for Public Endpoints

I have a Spring HttpSecurity configuration as
#Override
protected void configure(HttpSecurity http) throws Exception {
http
.sessionManagement()
.sessionCreationPolicy(SessionCreationPolicy.STATELESS);
http.csrf().disable().httpBasic().and()
.authorizeRequests()
.antMatchers("/public/**").permitAll()
.antMatchers("/secure/**").authenticated()
.antMatchers("/backend/**").authenticated()
.antMatchers(HttpMethod.OPTIONS, "/**").permitAll();
}
It might be stupid for the client to set the Authorization Header for '/public/**' endpoints.
However, I noticed Spring Security attempts to authenticate tries to create an authenticated session for even public requests because the Authorization Header was provided.
Should the HttpSecurity config not override this behaviour?
Answered in the comments:
No it shouldn't... Permit all is something different as not secured at all. For the latter override the 'configure(WebSecurity)' and use the 'ignoring' for no security at all.

Mix HttpBasic and FormLogin in Spring Security with Spring-boot-starter

I use spring-boot-starter 0.5.0.M6 with spring security to build my application which contains:
"/admin/"**: should be accessible to anyone have role ADMIN, form-based login
"/api/"**: should be accessible to anyone have role API, http basic login
My first attempt was:
#Override
protected void configure(HttpSecurity http) throws Exception {
http
.authorizeRequests()
.antMatchers("/resources/**").permitAll()
.antMatchers("/admin/**").hasRole("ADMIN")
.and()
.formLogin()
.defaultSuccessUrl("/admin/home")
.loginPage("/login")
.permitAll()
.and()
.logout()
.logoutRequestMatcher(new AntPathRequestMatcher("/logout", "GET"))
.permitAll();
http
.authorizeRequests()
.antMatchers("/api/**").hasRole("API")
.and()
.httpBasic();
}
With this approach:
all the "/admin/" and "/api/" can authentication use both basic & form-based login. This is not a critical issue.
when any security issue occurred, eg: authentication failed, or authorization failed, the login form is shown. This is a critical issue, I want if /api/** get authentication failed or authorization failed, it show the basic authentication popup with 401/403 status code.
Then I try with the solution from https://github.com/spring-projects/spring-security-javaconfig/blob/master/samples-web.md#sample-multi-http-web-configuration, but I only able to secure either /api/** or /admin/** but not both, depends on which one I annotated with #Order.
Please give me a hand.
Thanks much
For your api part, use the following. Note the first ant matcher that limits the scope of what is filtered by this security configuration. That was the part I did not understand at first from your reference.
#Configuration
#Order(1)
public static class ApiWebSecurityConfigurationAdapter extends WebSecurityConfigurerAdapter {
#Override
protected void configure(HttpSecurity http) throws Exception {
http.csrf().disable();
// the ant matcher is what limits the scope of this configuration.
http.antMatcher("/api/**").authorizeRequests()
.antMatchers("/api/**").authenticated()
.and().httpBasic().realmName("Sourcing API");
}
}
