# 管理后台开发文档 - Part 2（AdminService 接口 + 实现）
|
||||
|
||||
## 一、AdminService 接口
|
||||
|
||||
```java
|
||||
package com.openclaw.service.admin;
|
||||
|
||||
import com.baomidou.mybatisplus.core.metadata.IPage;
|
||||
import com.openclaw.dto.admin.*;
|
||||
import com.openclaw.entity.PointsRule;
|
||||
import com.openclaw.vo.admin.*;
|
||||
import java.util.List;
|
||||
|
||||
public interface AdminService {
|
||||
// 看板
|
||||
DashboardVO getDashboard();
|
||||
|
||||
// 用户
|
||||
IPage<AdminUserVO> listUsers(AdminUserQueryDTO query);
|
||||
AdminUserVO getUserDetail(Long userId);
|
||||
void banUser(Long userId, String reason);
|
||||
void unbanUser(Long userId);
|
||||
void adjustPoints(Long userId, int delta, String remark);
|
||||
|
||||
// Skill 审核
|
||||
IPage<AdminSkillVO> listSkills(AdminSkillQueryDTO query);
|
||||
void auditSkill(SkillAuditDTO dto, Long auditorId);
|
||||
void offlineSkill(Long skillId, String reason);
|
||||
|
||||
// 订单 / 退款
|
||||
IPage<AdminOrderVO> listOrders(AdminOrderQueryDTO query);
|
||||
void processRefund(Long refundId, String action, String remark, Long operatorId);
|
||||
|
||||
// 积分规则
|
||||
List<PointsRule> listPointsRules();
|
||||
void updatePointsRule(Long ruleId, int points);
|
||||
}
|
||||
```

## 二、AdminServiceImpl.java
|
