我知道，有很多关于该主题的文章，但是我有一个问题，我找不到任何解决方案。

我有一个经典的spring security java config：

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

@Autowired
private AuctionAuthenticationProvider auctionAuthenticationProvider;

@Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
    auth.authenticationProvider(auctionAuthenticationProvider);
}

@Override
protected void configure(HttpSecurity http) throws Exception {
    http.httpBasic();

    ExpressionUrlAuthorizationConfigurer<HttpSecurity>.ExpressionInterceptUrlRegistry authorizeRequest = http.authorizeRequests();

    configureAdminPanelAccess(authorizeRequest);
    configureFrontApplicationAccess(authorizeRequest);
    configureCommonAccess(authorizeRequest);

    http.csrf()
        .csrfTokenRepository(csrfTokenRepository()).and()
        .addFilterAfter(csrfHeaderFilter(), CsrfFilter.class);

    http.logout()
        .clearAuthentication(true)
        .invalidateHttpSession(true);
}
...
}

另外，我有两种控制器方法，其中我通过AJAX从Web应用程序登录/注销。

当我想注销时，我首先调用此方法，我希望该方法清除用户会话并清除安全上下文中的所有内容。

@Override
@RequestMapping(value = "/logout", method = GET, produces = APPLICATION_JSON_UTF8_VALUE)
public ResponseEntity<Boolean> logout(final HttpServletRequest request, final HttpServletResponse response) {
    Authentication auth = SecurityContextHolder.getContext().getAuthentication();
    if (auth != null){
        new SecurityContextLogoutHandler().logout(request, response, auth);
    }

    return new ResponseEntity<>(Boolean.TRUE, HttpStatus.OK);
}

之后，我重新加载客户端Web应用程序，并且每次重新加载客户端Web应用程序时，我都会通过调用以下控制器方法来检查用户是否已通过身份验证：

@Override
@RequestMapping(value = "/user", method = GET, produces = APPLICATION_JSON_UTF8_VALUE)
public ResponseEntity<UserDetails> user() {
    Object principal = SecurityContextHolder.getContext().getAuthentication().getPrincipal();
    if (principal instanceof UserDetails) {
        return new ResponseEntity<>((UserDetails) principal, HttpStatus.OK);
    }

    return null;
}

我在这里收到了最后一个经过身份验证的用户。在以前的注销方法中，Spring注销似乎无效。

请记住，我尝试使用以下代码注销，但未成功：

   @Override
   @RequestMapping(value = "/logout", method = GET, produces = APPLICATION_JSON_UTF8_VALUE)
    public ResponseEntity<Boolean> logout(final HttpServletRequest request) {
     try {
         request.logout();

         return new ResponseEntity<>(Boolean.TRUE, HttpStatus.OK);
     } catch (ServletException ex) {
         if (LOG.isDebugEnabled()) {
             LOG.debug("There is a problem with the logout of the user", ex);
         }
    }

您是否知道我在配置和注销过程中错过了什么？
