Spring Security OAuth2 Provider 之 自定义开发

Spring OAuth2默认提供的功能难免无法满足需求，需要特殊定制，这里列举常见的几个需要特殊开发的地方。

（1）自定义生成授权码 

默认规则是：6位随机英数字。 
可以通过扩展AuthorizationCodeServices来覆写已有的生成规则。通过覆写createAuthorizationCode()方法可以设置成任意的生成规则。 
比如，这里实现返回32位随机英数字。 

@Configuration
@EnableAuthorizationServer
public class AuthorizationServerConfiguration extends AuthorizationServerConfigurerAdapter {

    @Bean
    protected AuthorizationCodeServices authorizationCodeServices() {
        return new CustomJdbcAuthorizationCodeServices(dataSource());
    }

}

public class CustomJdbcAuthorizationCodeServices extends JdbcAuthorizationCodeServices {

    private RandomValueStringGenerator generator = new RandomValueStringGenerator();

    public CustomJdbcAuthorizationCodeServices(DataSource dataSource) {
        super(dataSource);
        this.generator = new RandomValueStringGenerator(32);
    }

    public String createAuthorizationCode(OAuth2Authentication authentication) {
        String code = this.generator.generate();
        store(code, authentication);
        return code;
    }

}

效果如下： 


（2）自定义生成令牌 

默认规则是：UUID。 
Spring OAuth2提供了一个操作Token的接口TokenEnhancer，通过实现它可以任意操作accessToken和refreshToken。比如，这里实现将Token中的横线去掉。 

@Configuration
@EnableAuthorizationServer
public class AuthorizationServerConfiguration extends AuthorizationServerConfigurerAdapter {

    @Bean
    public TokenEnhancer tokenEnhancer() {
        return new CustomTokenEnhancer();
    }

}

public class CustomTokenEnhancer implements TokenEnhancer {

    @Override
    public OAuth2AccessToken enhance(OAuth2AccessToken accessToken, OAuth2Authentication authentication) {
        if (accessToken instanceof DefaultOAuth2AccessToken) {
            DefaultOAuth2AccessToken token = ((DefaultOAuth2AccessToken) accessToken);
            token.setValue(getNewToken());

            OAuth2RefreshToken refreshToken = token.getRefreshToken();
            if (refreshToken instanceof DefaultOAuth2RefreshToken) {
                token.setRefreshToken(new DefaultOAuth2RefreshToken(getNewToken()));
            }

            Map<String, Object> additionalInformation = new HashMap<String, Object>();
            additionalInformation.put("client_id", authentication.getOAuth2Request().getClientId());
            token.setAdditionalInformation(additionalInformation);

            return token;
        }
        return accessToken;
    }

    private String getNewToken() {
        return UUID.randomUUID().toString().replace("-", "");
    }

}

效果如下： 


（3）自定义授权页面 

默认的定义如下： 
org.springframework.security.oauth2.provider.endpoint.AuthorizationEndpoint 

引用

  private String userApprovalPage = "forward:/oauth/confirm_access"; 
  private String errorPage = "forward:/oauth/error";

org.springframework.security.oauth2.provider.endpoint.WhitelabelApprovalEndpoint 

引用

  @RequestMapping({"/oauth/confirm_access"}) 
  public ModelAndView getAccessConfirmation(Map<String, Object> model, HttpServletRequest request) throws Exception { 
    // ... 
  }

org.springframework.security.oauth2.provider.endpoint.WhitelabelErrorEndpoint 

引用

  @RequestMapping({"/oauth/error"}) 
  public ModelAndView handleError(HttpServletRequest request) { 
    // ... 
  }

设置新的URL： 

@Configuration
@EnableAuthorizationServer
public class AuthorizationServerConfiguration extends AuthorizationServerConfigurerAdapter {
    @Autowired
    private AuthorizationEndpoint authorizationEndpoint;

    @PostConstruct
    public void init() {
        authorizationEndpoint.setUserApprovalPage("forward:/oauth/my_approval_page");
        authorizationEndpoint.setErrorPage("forward:/oauth/my_error_page");
    }
}

页面实现： 

@Controller
@SessionAttributes({ "authorizationRequest" })
public class OAuthController {

    @RequestMapping({ "/oauth/my_approval_page" })
    public String getAccessConfirmation(Map<String, Object> model, HttpServletRequest request) throws Exception {
        @SuppressWarnings("unchecked")
        Map<String, String> scopes = (Map<String, String>) (model.containsKey("scopes") ? model.get("scopes") : request.getAttribute("scopes"));
        List<String> scopeList = new ArrayList<String>();
        for (String scope : scopes.keySet()) {
            scopeList.add(scope);
        }
        model.put("scopeList", scopeList);
        return "oauth_approval";
    }

    @RequestMapping({ "/oauth/my_error_page" })
    public String handleError(Map<String, Object> model, HttpServletRequest request) {
        Object error = request.getAttribute("error");
        String errorSummary;
        if (error instanceof OAuth2Exception) {
            OAuth2Exception oauthError = (OAuth2Exception) error;
            errorSummary = HtmlUtils.htmlEscape(oauthError.getSummary());
        } else {
            errorSummary = "Unknown error";
        }
        model.put("errorSummary", errorSummary);
        return "oauth_error";
    }
}

/src/main/resources/templates/oauth_approval.html 

<!DOCTYPE HTML>
<html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:th="http://www.thymeleaf.org">
<head>
  <title>approval</title>
  <meta charset="utf-8"/>
</head>
<body>
  <div class="container">
    <div class="row">
      <div class="col-md-12 well">
        <h3>授权页</h3>
        应用名 : <span th:text="${session.authorizationRequest.clientId}">clientId</span>

        <form id='confirmationForm' name='confirmationForm' th:action="@{/oauth/authorize}" method='post'>
            <input name='user_oauth_approval' value='true' type='hidden' />
            <input th:name="${s}" value="true" type="hidden" th:each="s : ${scopeList}" />
            <input name='authorize' value='授权' type='submit' />
        </form>
      </div>
    </div>
  </div>
</body>
</html>

/src/main/resources/templates/oauth_error.html 

<!DOCTYPE HTML>
<html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:th="http://www.thymeleaf.org">
<head>
  <title>error</title>
  <meta charset="utf-8"/>
</head>
<body>
  <div class="container">
    <div class="row">
      <div class="col-md-12 well">
        <h3>错误</h3>
        <p style="color:red;">出错了！不能继续授权操作！</p>
        <p th:utext="${errorSummary}">errorSummary
      </div>
    </div>
  </div>
</body>
</html>

效果如下： 
 


（4）自定义用户登录页面 
这部分应该属于SpringSecurity范畴的。 

创建用户表 

CREATE TABLE account
(
  id serial NOT NULL,
  user_name character varying(50),
  email character varying(255),
  password character varying(512),
  role_string character varying(50),
  CONSTRAINT account_pkey PRIMARY KEY (id)
);

INSERT INTO account(user_name, email, password, role_string)
    VALUES ('user', 'user@sample.com', '123', 'ROLE_USER');

配置SpringSecurity 

@Configuration
@Order(SecurityProperties.ACCESS_OVERRIDE_ORDER)
@EnableWebSecurity
static class SecurityConfig extends WebSecurityConfigurerAdapter {
    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.authenticationProvider(authenticationProvider);
    }

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

      http.antMatcher("/oauth/**")
        .authorizeRequests()
          .antMatchers("/oauth/index").permitAll()
          .antMatchers("/oauth/token").permitAll()
          .antMatchers("/oauth/check_token").permitAll()
          .antMatchers("/oauth/confirm_access").permitAll()
          .antMatchers("/oauth/error").permitAll()
          .antMatchers("/oauth/my_approval_page").permitAll()
          .antMatchers("/oauth/my_error_page").permitAll()
          .anyRequest().authenticated()
        .and()
          .formLogin()
          .loginPage("/oauth/index")
          .loginProcessingUrl("/oauth/login");
    }
    @Autowired
    private CustomAuthenticationProvider authenticationProvider;
}

@Configuration
@MapperScan("com.rensanning")
@EnableTransactionManagement(proxyTargetClass = true)
static class RepositoryConfig {
}

用户登录处理部分 

@Component
public class CustomAuthenticationProvider implements AuthenticationProvider {

  @Autowired
  private AccountService accountService;

  @Override
  public Authentication authenticate(Authentication authentication) throws AuthenticationException {

    String name = authentication.getName();
    String password = authentication.getCredentials().toString();

    Account account = accountService.authUser(name, password);
    if (account == null) {
      throw new AuthenticationCredentialsNotFoundException("Account is not found.");
    }

    List<GrantedAuthority> grantedAuths = AuthorityUtils.createAuthorityList(account.getRoleString());
    return new UsernamePasswordAuthenticationToken(name, password, grantedAuths);
  }

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

@Service
public class AccountService {

  @Autowired
  private AccountRepository accountRepository;

  public Account authUser(String userName, String password) {
    Account u = accountRepository.findByUserName(userName);
    if (u == null) {
      return null;
    }
    if (!u.getPassword().equals(password)) {
      return null;
    }
    return u;
  }

}

public interface AccountRepository {
  @Select("select id, user_name as userName, email, password, role_string as roleString from account where user_name=#{user_name}")
  Account findByUserName(String userName);
}

@SuppressWarnings("serial")
public class Account implements Serializable {
  private Integer id;
  private String userName;
  private String email;
  private String password;
  private String roleString;
  // ...setter/getter
}

 

完成的Client->ResoureServer->AuthServer的执行过程：

3 楼 IT小新 2017-10-27  

求该例子得示例代码呗，谢谢了

2 楼 xu_yuan 2017-10-24  

LS少写了thymeleaf的配置，如果不加的话，是不能识别thymeleaf语法的html文件的。会导致controller虽然返回了oauth_approval，但是却报错error 找不到mapping

配置自定义授权页
POM.xml 需要加入以下配置

<!---模板引擎：网页路径渲染-->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>

application.yml 需要加入以下配置

spring:
  thymeleaf:
    prefix: classpath:/templates/ # 模板路径

本例有没有相关代码实例，根据你上面的配置没搞成功，登录后又返回登录页面。
