Question

我使用Spring Boot 1.2.1.RELEASE创建了一个Web服务。这有我在控制器中定义的POST ang GET方法。我还使用应用程序数据库中自己的用户凭据配置了身份验证，并且还实现了OAuth。

这是我的Application.class，它具有所有必要的配置。

@Configuration
@ComponentScan
@EnableAutoConfiguration
public class Application extends SpringBootServletInitializer {

  public static void main(String[] args) {
    SpringApplication.run(Application.class, args);
  }

  @Override
  protected SpringApplicationBuilder configure(
      SpringApplicationBuilder application) {
    return application.sources(Application.class);
  }

  @Service
  protected static class ApplicationUserDetailsService implements UserDetailsService {

    @Autowired
    private UserRepository userRepository;

    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
      User user = this.userRepository.findByUsername(username);

      if (user == null) {
        return null;
      }

      List<GrantedAuthority> auth = AuthorityUtils.commaSeparatedStringToAuthorityList("ROLE_USER");

      String password = user.getPassword();

      return new org.springframework.security.core.userdetails.User(username, password, auth);
    }
  }

  @Configuration
  @EnableGlobalMethodSecurity(prePostEnabled = true)
  @EnableWebSecurity
  protected static class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    private ApplicationUserDetailsService applicationUserDetailsService;

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

    @Bean   
    @Override
    protected AuthenticationManager authenticationManager() throws Exception {
      return super.authenticationManager();
    }

  }

  @Configuration
  @EnableResourceServer
  protected static class ResourceServerConfig extends ResourceServerConfigurerAdapter {

    @Override
    public void configure(HttpSecurity http) throws Exception {
      http.requestMatchers()
        .and()
        .authorizeRequests()
        .antMatchers("/user/**").access("#oauth2.hasScope('read')")
        .antMatchers("/car/**").access("#oauth2.hasScope('read')")
        .antMatchers("/transaction/**").access("#oauth2.hasScope('read')");
    }

  } 

  @Configuration
  @EnableAuthorizationServer
  protected static class AuthorizationServerConfig extends
      AuthorizationServerConfigurerAdapter {

    @Autowired
    private AuthenticationManager authenticationManager;

    @Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints) {
      endpoints.authenticationManager(authenticationManager);
    }

    @Override
    public void configure(ClientDetailsServiceConfigurer clients)
        throws Exception {
      clients.inMemory()
          .withClient("my-trusted-client")
          .authorizedGrantTypes("authorization_code", "password",
              "refresh_token")
          .authorities("ROLE_CLIENT", "ROLE_TRUSTED_CLIENT")
          .scopes("read", "write", "trust")
          .accessTokenValiditySeconds(60);
    }

    @Override
    public void configure(AuthorizationServerSecurityConfigurer security)
        throws Exception {
      security.allowFormAuthenticationForClients();
    }

  }

}

这是我的控制员之一。

@RestController
@RequestMapping("/transaction")
public class TransactionController {

  @Autowired
  private TransactionHeaderRepository transactionHeaderRepository;

  @RequestMapping("/header/{id}")
  public ResponseEntity<TransactionHeader> findHeaderById(@PathVariable UUID id) {
    return new ResponseEntity<>(this.transactionHeaderRepository.findById(id), HttpStatus.OK);
  }

  @RequestMapping(value = "/header/create", method = RequestMethod.POST)
  public ResponseEntity<TransactionHeader> createHeader(@RequestBody TransactionHeader transactionHeader) {
    this.transactionHeaderRepository.save(transactionHeader);
    this.transactionLineRepository.save(transactionHeader.getTransactionLines());
    return new ResponseEntity<>(HttpStatus.OK);
  }

  @RequestMapping(value = "/header/update", method = RequestMethod.POST)
  public ResponseEntity<TransactionHeader> updateHeader(@RequestBody TransactionHeader transactionHeader) {
    return new ResponseEntity<TransactionHeader>(this.transactionHeaderRepository.save(transactionHeader), HttpStatus.OK);
  }

  @RequestMapping(value = "/header/delete", method = RequestMethod.POST)
  public ResponseEntity<TransactionHeader> deleteHeader(@RequestBody TransactionHeader transactionHeader) {
    this.transactionHeaderRepository.delete(transactionHeader);
    return new ResponseEntity<TransactionHeader>(HttpStatus.OK);
  }

}

除了我想限制用户并允许他们仅更新自己的数据的部分外，一切正常。

我应该怎么做呢？这应该在控制器中完成吗？或者spring是否提供了某种内置功能来处理这个问题？

感谢您的反馈。

Answer 1

要执行此操作，您可以创建自己的自定义注释（@Useridentifier）并使用它来映射到UserDetails.UserId（您的用户PK）。将其放在包含用户PK的DTO上。

接下来，您可以创建另一个放置在端点上的注释（@Useridentifiercheck）（如requestMapping）。如果值不匹配，则抛出异常并返回401或将userId替换为OAuth属性中的userId（如果将userId存储在OAuth数据中）。

注意：所有这些也可以通过服务和一些反思来完成，但我喜欢注释：）

失败的地方如果你有一个更新FK表没有UserId的休息点，那么这个想法就会失败。

示例

table - User { long userId; nvarchar name; long address_fk; } table - Address { long addressId; nvarchar postcode; }

在这里我们可以更新地址，但是如果没有一些联接给我们userId，我们无法知道我们是否“被授权”编辑地址。

服务器端问题 需要小心为管理员删除此功能，否则，他们将无法更新其他人的数据以太...

网关API

另一个例子是创建一个靠近UI的网关API（例如ExpressJS服务于React和自定义API）

UI会话可以存储在Express中并进行过滤，以确保自动更新的任何请求都具有“正确的”UserID。

例如：坏人发送以下JSON

put: { userId: 69, password: powned, firstname: Paul }

Express API接受DTO并剥离未授权的输入（userId，密码）。请注意，在这种情况下，请求将被传递到API，用正确的会话值替换“传入”userId。

核心API将位于VPN防火墙后面，并使用客户OAuth令牌进行限制。

如何在spring boot中实现用户级别的特定授权？
