I am trying to implement HTTP Basic Auth using Spring Security Annotations.
I have a REST endpoint, defined as below:
@RequestMapping("/foo/")
I want people only in Admin role to access /foo/ endpoint.
Next, I am configuring Spring Security, as shown below:
@Configuration
@EnableWebSecurity
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {
private static String REALM="MY_TEST_REALM";
@Autowired
public void configureGlobalSecurity(AuthenticationManagerBuilder auth) throws Exception {
auth.inMemoryAuthentication().withUser("bill").password("abc123").roles("ADMIN");
auth.inMemoryAuthentication().withUser("tom").password("abc123").roles("USER");
}
@Override
protected void configure(HttpSecurity http) throws Exception {
//http.csrf().disable()
http
.authorizeRequests()
.antMatchers("/foo/").hasRole("ADMIN")
.and().httpBasic().realmName(REALM).authenticationEntryPoint(getBasicAuthEntryPoint())
.and().sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS);//We don't need sessions to be created.
}
@Bean
public CustomBasicAuthenticationEntryPoint getBasicAuthEntryPoint(){
return new CustomBasicAuthenticationEntryPoint();
}
/* To allow Pre-flight [OPTIONS] request from browser */
@Override
public void configure(WebSecurity web) throws Exception {
web.ignoring().antMatchers(HttpMethod.OPTIONS, "/**");
}
}
So, I only want bill username with password abc123 to be able to call the REST endpoint.
Next, I define the error that should be returned
public class CustomBasicAuthenticationEntryPoint extends BasicAuthenticationEntryPoint {
@Override
public void commence(final HttpServletRequest request,
final HttpServletResponse response,
final AuthenticationException authException) throws IOException, ServletException {
//Authentication failed, send error response.
response.setStatus(HttpServletResponse.SC_UNAUTHORIZED);
response.addHeader("WWW-Authenticate", "Basic realm=" + getRealmName() + "");
PrintWriter writer = response.getWriter();
writer.println("HTTP Status 401 : " + authException.getMessage());
}
@Override
public void afterPropertiesSet() throws Exception {
setRealmName("MY_TEST_REALM");
super.afterPropertiesSet();
}
}
I tried testing with Postman, I am using Basic Auth with the correct credentials but I always get the 401 Error. Am I missing any step?
Please see the screenshot below from Postman. Am I missing any header?
and, here's the Header section
(I am hiding base URL in the above screenshot)
