这具有任何用户使用“授权”标头发出请求以访问所有资源的结果。没有Authorization标头的用户无法请求使用令牌。
我花了很多时间尝试从其他示例中提取，并从HTTPSecurity类及其相关类中读取文档，但我无法理解如何实现此配置。
非常感谢任何帮助！
由于项目的性质，我不得不遵循一个涉及oauth2略微缩减版本的协议。不幸的是，这意味着实现了Spring Security中已经提供的许多东西（即我无法使用Spring-Security-oauth2或Spring Security 5）。以满足我的特定需求。我真的很感激您的任何建议。

我找到了tutorial的解决方案，该解决方案涉及实现我自己的整个授权流程版本。但它的确有效！
我的SecurityConfig.java类变为：
@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
private final AuthenticationSuccessHandler loginSuccessfulHandler;
private final AuthenticationFailureHandler loginFailureHandler;
private final AccessDeniedHandler customAccessDeniedHandler;
private final AuthenticationEntryPoint customAuthenticationEntryPoint;
@Autowired
public SecurityConfig(AuthenticationSuccessHandler loginSuccessfulHandler, AuthenticationFailureHandler loginFailureHandler, AccessDeniedHandler customAccessDeniedHandler, AuthenticationEntryPoint customAuthenticationEntryPoint) {
this.loginSuccessfulHandler = loginSuccessfulHandler;
this.loginFailureHandler = loginFailureHandler;
this.customAccessDeniedHandler = customAccessDeniedHandler;
this.customAuthenticationEntryPoint = customAuthenticationEntryPoint;
}
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.inMemoryAuthentication()
.withUser("user").password("password").roles("USER")
.and()
.withUser("admin").password("password").roles("ADMIN");
}
@Override
protected void configure(HttpSecurity http) throws Exception {
http
.csrf().disable() // disable CSRF for this application
.formLogin() // Using form based login instead of Basic Authentication
.loginProcessingUrl("/oauth/token") // Endpoint which will process the authentication request. This is where we will post our credentials to authenticate
.successHandler(loginSuccessfulHandler)
.failureHandler(loginFailureHandler)
.and()
.authorizeRequests()
.antMatchers("/oauth/token").permitAll() // Enabling URL to be accessed by all users (even un-authenticated)
.antMatchers("/swagger-ui.html").permitAll()
//.antMatchers("/secure/admin").access("hasRole('ADMIN')") // Configures specified URL to be accessed with user having role as ADMIN
.anyRequest().authenticated() // Any resources not mentioned above needs to be authenticated
.and()
.exceptionHandling().accessDeniedHandler(customAccessDeniedHandler)
.authenticationEntryPoint(customAuthenticationEntryPoint)
.and()
.anonymous().disable(); // Disables anonymous authentication with anonymous role.
}
所以我必须通过实现现有的接口来实现我的登录（成功/失败）处理程序等。现在我只需要实现我自己的AuthenticationMangager而不是当前正在使用的内存中配置。
@dur感谢您的帮助！ :)
