spring boot security + rest not working [closed]

Hello. I have never worked with spring boot before and now I decided to try making a simple spring boot application + security + rest + hibernate + postgreSQL. A snag occurred with access to the rest address of the registration of a new user writes:

"status": 404, "error": "Not Found", "message": "No message available", "path": "/rest/registration/save" 

When I turn off spring security, access to the address is carried out without problems.

Springsecurity.java

 @Configuration @EnableWebSecurity(debug=true) @EnableGlobalMethodSecurity(securedEnabled = true) public class SecurityConfig extends WebSecurityConfigurerAdapter { @Autowired @Qualifier("IUserDetailsService") private UserDetailsService detailsService; @Override protected void configure(AuthenticationManagerBuilder auth) throws Exception { auth.inMemoryAuthentication().withUser("user").password("1234").roles("USER"); auth.userDetailsService(detailsService).passwordEncoder(passwordEncoder()); } @Override protected void configure(HttpSecurity http) throws Exception { http.authorizeRequests().antMatchers("/**", "/login/**", "/registration/**").permitAll(); http.authorizeRequests().antMatchers("/admin").access("hasAnyRole('ADMIN')"); http.formLogin() .loginPage("/login") .loginProcessingUrl("/j_spring_security_check") .usernameParameter("j_username") .passwordParameter("j_password") .defaultSuccessUrl("/") .permitAll(); http.logout() .permitAll() .logoutUrl("/logout") .logoutSuccessUrl("/") .invalidateHttpSession(true) .and() .exceptionHandling().accessDeniedPage("/403"); } @Bean public BCryptPasswordEncoder passwordEncoder() { return new BCryptPasswordEncoder(); } @Bean public AuthenticationManager authenticationManagerBean() throws Exception { return super.authenticationManagerBean(); } } 

RegistrationRestController.java

 @RestController @AllArgsConstructor @RequestMapping(value = "/rest/registration") public class RegistrationRestController { private final UsersService usersService; @PostMapping(value = "/save") public void registrationNewUser(@RequestBody Users user) { usersService.saveNewUser(user); } } 

Application.java

 @SpringBootApplication public class Application extends SpringBootServletInitializer { @Override protected SpringApplicationBuilder configure(SpringApplicationBuilder springApplicationBuilder) { return springApplicationBuilder.sources(Application.class); } public static void main(String[] args) { SpringApplication.run(Application.class, args); } } 

I don’t post all the code because there’s no point in models or repositories and other classes. What may be missing in the application for the normal functioning of the class annotated @RestController?
