spring - 未调用自定义 AuthenticationProvider

Question

我想要一个基本的受身份验证保护的 REST 应用程序。我遵循了 http://www.baeldung.com/spring-security-authentication-provider 中的一般说明为了让安全工作。

我最终创建了 AuthenticationProvider 的实现，但它永远不会被 Spring 调用。所有请求都以错误结束:

{"timestamp":1460199213227,"status":401,"error":"Unauthorized","message":"Full authentication is required to access this resource","path":"/test"}

没有 AuthenticationProvider 做任何事情。

该应用程序是基于注释的，以下是相关部分:

安全设置

@Configuration
@Order(SecurityProperties.ACCESS_OVERRIDE_ORDER)
public class ApplicationSecurity extends WebSecurityConfigurerAdapter {
    @Autowired
    CustomAuthenticationProvider authenticationProvider;

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

    @Override
    public void configure(HttpSecurity http) throws Exception {
        http
                .csrf().disable()
                .authenticationProvider(authenticationProvider)
                .authorizeRequests()
                .anyRequest().authenticated().and().httpBasic();
    }
}

身份验证提供者

@Component
public class CustomAuthenticationProvider implements AuthenticationProvider {
    @Autowired
    private UserDAO userDAO;
    @Autowired
    private Authenticator authenticator;

    @Override
    public Authentication authenticate(Authentication authentication) throws AuthenticationException {
        // This never gets called, I checked with debugger
        String username = authentication.getName();
        String password = authentication.getCredentials().toString();

        User user = userDAO.findByUsername(username);
        User authenticatedUser = authenticator.authenticate(user, password);
        if (authenticatedUser == null){
            throw new RESTAuthenticationException("Auth failed");
        }

        List<GrantedAuthority> authorityList = new ArrayList<>();
        return new UsernamePasswordAuthenticationToken(user, authorityList);
    }

    @Override
    public boolean supports(Class<?> aClass) {
        return aClass.equals(UsernamePasswordAuthenticationToken.class);
    }
}

Controller

@RestController
public class UserController {
    @RequestMapping(value = "/test")
    public ResponseEntity test(@AuthenticationPrincipal User user) {
        return ResponseEntity.ok().body(user);
    }
}

Answer 1

您收到状态代码为 401 的响应。这是 "unauthorized" http status code .这可能是由您的请求中缺少/格式错误的 Authorization header 引起的。

您正在使用 Http-Basic :它需要在请求中包含以下 header :

Authorization: Basic QWxhZGRpbjpPcGVuU2VzYW1l

其中字符串 QWxhZGRpbjpPcGVuU2VzYW1l 是字符串 <user>:<password> base64 编码。
