我正在尝试创建一个由 FF4J 提供的 Spring Boot 启动器支持的独立功能标志服务器（集中管理的功能标志微服务）。我也能够使用 Web 控制台和 REST API 启动并运行它。我现在正在尝试添加对 wiki 中提供的自定义授权管理器的支持，但根据那里提供的示例，我不清楚授权管理器在从不同的访问权限时如何知道用户上下文实现该功能的微服务。下面我提供了所有相关的代码片段。如果您在CustomAuthorizationManager课堂上注意到，我有一个currentUserThreadLocal变量，不确定如何或谁将在运行时设置该变量，以便 FF4J 验证用户的角色。对此的任何帮助都非常感谢，因为我在理解它的工作原理时遇到了问题。
另请注意，授权管理器中有一个toJson方法需要被覆盖，不确定需要去那里，任何帮助也很感激。
自定义授权管理器
public class CustomAuthorizationManager implements AuthorizationsManager {
private static final Logger LOG = LoggerFactory.getLogger(FeatureFlagServerFeignTimeoutProperties.class);
private ThreadLocal<String> currentUserThreadLocal = new ThreadLocal<String>();
private List<UserRoleBean> userRoles;
@Autowired
private SecurityServiceFeignClient securityServiceFeignClient;
@PostConstruct
public void init() {
try {
userRoles = securityServiceFeignClient.fetchAllUserRoles();
} catch (Exception ex) {
LOG.error("Error while loading user roles", ex);
userRoles = new ArrayList<>();
}
}
@Override
public String getCurrentUserName() {
return currentUserThreadLocal.get();
}
@Override
public Set<String> getCurrentUserPermissions() {
String currentUser = getCurrentUserName();
Set<String> roles = new HashSet<>();
if (userRoles.size() != 0) {
roles = userRoles.stream().filter(userRole -> userRole.getUserLogin().equals(currentUser))
.map(userRole -> userRole.getRoleName()).collect(Collectors.toSet());
} else {
LOG.warn(
"No user roles available, check startup logs to check possible errors during loading of user roles, returning empty");
}
return roles;
}
@Override
public Set<String> listAllPermissions() {
Set<String> roles = new HashSet<>();
if (userRoles.size() != 0) {
roles = userRoles.stream().map(userRole -> userRole.getRoleName()).collect(Collectors.toSet());
} else {
LOG.warn(
"No user roles available, check startup logs to check possible errors during loading of user roles, returning empty");
}
return roles;
}
@Override
public String toJson() {
return null;
}
}

// Set authorization

ff4j.setAuthorizationsManager(custAuthorizationManager);
// Enable audit mode
ff4j.audit(true);
return ff4j;
