Question

当我尝试将Chrome浏览器的POSTMAN插件中的JSON有效负载发送到作为REST URL公开的控制器时，我收到以下错误 - http://localhost:8080/services/acc/create

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

我选择BasicAuth作为授权类型，并在POSTMAN中将JSON有效负载发送到REST URL时输入用户名和密码。

1）控制器类

@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）安全配置类

@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）Spring安全依赖

<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>

我在POSTMAN中发送身份验证凭据。但仍然为什么我得到上述例外。

您使用springSecurityFilterChain创建了WebSecurityConfigurerAdapter，请参阅Spring Security Reference：

第一步是创建Spring Security Java配置。该配置创建一个称为springSecurityFilterChain的Servlet过滤器，它负责应用程序中的所有安全性（保护应用程序URL，验证提交的用户名和密码，重定向到登录表单等）。

但你没有使用它（它不在你的堆栈跟踪中）。

您必须注册springSecurityFilterChain。如果您有Servlet 3.0+环境，请参阅Spring Security Reference：

使用Spring MVC的AbstractSecurityWebApplicationInitializer

如果我们在我们的应用程序的其他地方使用Spring，我们可能已经有一个WebApplicationInitializer正在加载我们的Spring配置。如果我们使用以前的配置，我们会收到错误。相反，我们应该使用现有的ApplicationContext注册Spring Security。例如，如果我们使用Spring MVC，我们的SecurityWebApplicationInitializer将如下所示：
import org.springframework.security.web.context.*;

public class SecurityWebApplicationInitializer
  extends AbstractSecurityWebApplicationInitializer {

}
这只会为应用程序中的每个URL注册springSecurityFilterChain过滤器。之后，我们将确保在现有的ApplicationInitializer中加载WebSecurityConfig。例如，如果我们使用Spring MVC，它将被添加到getRootConfigClasses()
中
public class MvcWebApplicationInitializer extends
      AbstractAnnotationConfigDispatcherServletInitializer {

  @Override
  protected Class<?>[] getRootConfigClasses() {
      return new Class[] { WebSecurityConfig.class };
  }

  // ... other overrides ...
}

AuthenticationCredentialsNotFoundException：在安全上下文中找不到Authentication对象
