[SPRING] AuthenticationCredentialsNotFoundException : 보안 컨텍스트에서 인증 개체를 찾을 수 없습니다.

AuthenticationCredentialsNotFoundException : 보안 컨텍스트에서 인증 개체를 찾을 수 없습니다.

크롬 브라우저의 POSTMAN 플러그인에서 JSON 페이로드를 REST URL (http : // localhost : 8080 / services / acc / create)로 표시된 컨트롤러로 보내려고 할 때 아래 오류가 발생합니다.

SEVERE: Servlet.service() for servlet [dispatcher] in context with path [/services] threw exception [Request processing failed; nested exception is org.springframework.security.authentication.AuthenticationCredentialsNotFoundException: An Authentication object was not found in the SecurityContext] with root cause

JSON 페이로드를 POSTMAN의 REST URL로 보내는 동안 권한 유형으로 BasicAuth를 선택하고 사용자 이름과 암호를 입력했습니다.

1) 컨트롤러 클래스

@RestController
public class AccountRestController {

    @Autowired
    private AccountService accountService;

    @PreAuthorize("hasAnyRole('ADMINISTRATOR')")
    @RequestMapping(value= "/acc/create", method=RequestMethod.POST)
    public HotelDTO createHotel(@RequestBody AccountDTO accDTO) throws Exception{
        return accountService.create(accDTO);
    }
} 

2) 보안 구성 클래스

@Configuration
@EnableGlobalMethodSecurity(prePostEnabled = true)
@EnableWebSecurity
@ComponentScan(basePackages = "com.freelance", scopedProxy = ScopedProxyMode.INTERFACES)
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    @Qualifier("authenticationService")
    private UserDetailsService userDetailsService;

    @Bean
    @Override
    public AuthenticationManager authenticationManagerBean() throws Exception {
        return super.authenticationManagerBean();
    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService(userDetailsService);
        auth.authenticationProvider(authenticationProvider());
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
       http
                .authorizeRequests()
                .antMatchers("/user/**").permitAll()
                .anyRequest().fullyAuthenticated();
        http.httpBasic();
        http.csrf().disable();
    }

    @Bean
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }

    @Bean
    public DaoAuthenticationProvider authenticationProvider() {
        DaoAuthenticationProvider authenticationProvider = new DaoAuthenticationProvider();
        authenticationProvider.setUserDetailsService(userDetailsService);
        authenticationProvider.setPasswordEncoder(passwordEncoder());
        return authenticationProvider;
    }
}

3) 스프링 보안 의존성

<dependency>
    <groupId>org.springframework.security</groupId>
        <artifactId>spring-security-config</artifactId>
        <version>3.2.3.RELEASE</version>
   </dependency>
   <dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-web</artifactId>
    <version>3.2.3.RELEASE</version>
</dependency>

나는 POSTMAN에 인증 증명서를 보내고 있습니다. 하지만 여전히 위의 예외가 발생하는 이유는 무엇입니까?

해결법

1. ==============================

   1.WebSecurityConfigurerAdapter를 사용하여 springSecurityFilterChain을 만들었습니다. Spring Security Reference :

   WebSecurityConfigurerAdapter를 사용하여 springSecurityFilterChain을 만들었습니다. Spring Security Reference :

   하지만 당신은 그것을 사용하지 않았다 (당신의 스택 트레이스에는 없다).

   springSecurityFilterChain을 등록해야합니다. Servlet 3.0+ 환경을 가지고 있다면, Spring Security Reference :
