# 账务日志功能按钮 + 呆坏账恢复 Implementation Plan

> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.

**Goal:** 修复账务日志页功能按钮（撤销/退转款/预转存/呆坏账恢复）根据数据状态正确显示，不再硬编码 `false`；新增呆坏账恢复入口。

**Architecture:** 后端 `toPageResp()` 当前将 `canRevoke`/`canRefund`/`canPrestore` 硬编码为 `false`，`canRecoverBadDebt` 字段不存在。修复后根据 `LegacyLogRecord` 的 `objectType` + `resultStatus` + `approvalStatus` 动态判定；前端补 API 调用和按钮。

**Tech Stack:** Java 17 + Spring Boot (backend), Vue 3 + TypeScript (frontend)

---

## canXxx 判定规则

在 `toPageResp(LegacyLogRecord record)` 中按以下规则赋值：

| 字段 | 条件 | 说明 |
|---|---|---|
| `canRevoke` | `approvalStatus == "PENDING_APPROVAL"` | 待审批状态可撤销 |
| `canRefund` | `objectType == "PREPAID_REFUND" && resultStatus == "SUCCESS"` | 退转款成功后允许二次退款 |
| `canPrestore` | `objectType == "PREPAID_REFUND" && resultStatus == "SUCCESS"` | 退转款成功后允许转预存 |
| `canRecoverBadDebt` | `objectType == "BAD_DEBT_RECORD" && resultStatus == "SUCCESS"` | 坏账已执行可恢复为欠费 |

### Task 1: 后端 VO 加 canRecoverBadDebt

**Files:**
- Modify: `sw-business/sw-business-server/src/main/java/cn/com/emsoft/sw/business/controller/admin/accountingadjust/accountProcess/vo/AccountingAdjustLogPageRespVO.java`

- [ ] **Step 1: 在 VO 末尾 canPrestore 后添加字段**

```java
    @Schema(description = "是否可恢复呆坏账")
    private Boolean canRecoverBadDebt;
```

添加位置：紧跟 `private Boolean canPrestore;` 之后。

---

### Task 2: 后端 Service 修正 canXxx 赋值

**Files:**
- Modify: `sw-business/sw-business-server/src/main/java/cn/com/emsoft/sw/business/service/accountingadjust/accountProcess/AccountingAdjustLogProcessServiceImpl.java:520-522`

- [ ] **Step 1: 替换硬编码 false 为动态判定**

将 `toPageResp()` 中的三行：

```java
        respVO.setCanRevoke(false);
        respVO.setCanRefund(false);
        respVO.setCanPrestore(false);
```

替换为：

```java
        // 动态判定功能按钮可见性
        respVO.setCanRevoke("PENDING_APPROVAL".equals(record.approvalStatus));
        boolean refundEnabled = "PREPAID_REFUND".equals(record.objectType) && "SUCCESS".equals(record.resultStatus);
        respVO.setCanRefund(refundEnabled);
        respVO.setCanPrestore(refundEnabled);
        respVO.setCanRecoverBadDebt("BAD_DEBT_RECORD".equals(record.objectType) && "SUCCESS".equals(record.resultStatus));
```

**同时需要更新 `AccountingAdjustLogPageReqVO` 的 `copyReq` 方法：** 无需改动，canXxx 是响应字段。

---

### Task 3: 前端 API 加 recoverBadDebt

**Files:**
- Modify: `src/api/accountProcess/accountLog/index.ts`

- [ ] **Step 1: 添加接口类型和 API 方法**

在 `AccountingAdjustPageRespVO` 接口中添加 `canRecoverBadDebt` 字段，并在 `AccountLogApi` 对象中添加 `recoverBadDebt` 方法：

```typescript
// 在 AccountingAdjustPageRespVO 接口中添加
  canRecoverBadDebt?: boolean
```

```typescript
// 在 AccountLogApi 对象中添加（放在 revokeAccountLog 之前）
  // 账务日志呆坏账恢复
  recoverBadDebt: async (data: { adjustmentNo: string }) => {
    return await request.post<AccountingAdjustRespVO>({
      url: '/business/accounting-adjust/log-recover-bad-debt',
      data
    })
  },
```

---

### Task 4: 前端页面加呆坏账恢复按钮

**Files:**
- Modify: `src/views/accountProcess/accountLog/index.vue`

- [ ] **Step 1: 在 function 模板中添加按钮**

在现有三个按钮之后、`</div>` 之前添加：

```html
            <el-button
              v-if="scope.row.canRecoverBadDebt"
              link
              type="primary"
              @click="handleRecoverBadDebt(scope.row)"
            >
              <el-tooltip effect="dark" content="恢复呆坏账" placement="top">
                <Icon icon="ep:refresh-left" :size="18" />
              </el-tooltip>
            </el-button>
```

- [ ] **Step 2: 在 script 中添加处理函数**

在 `handlePrestore` 之后添加：

```typescript
const handleRecoverBadDebt = async (row: any) => {
  const adjustmentNo = row?.adjustmentNo
  if (!adjustmentNo) {
    message.warning('缺少调整单号，无法恢复')
    return
  }
  try {
    await message.confirm(`确认要将呆坏账调整单「${adjustmentNo}」恢复为欠费状态吗？`)
    await AccountLogApi.recoverBadDebt({ adjustmentNo })
    message.success('呆坏账已恢复为欠费')
    await getList()
  } catch (e: any) {
    if (e !== 'cancel' && e !== 'close') {
      message.error('恢复失败，请稍后重试')
    }
  }
}
```

### Task 5: 编译验证 + 提交

- [ ] **Step 1: 后端编译 + 测试**

```bash
cd /Volumes/Dpan/github/water-workspace/water-backend
mvn test -pl sw-business/sw-business-server -Dtest=AccountingAdjustLogProcessServiceImplTest -DfailIfNoTests=false 2>&1 | grep -E "Tests run|BUILD"
```

预期：Tests run: 4, Failures: 0, BUILD SUCCESS

- [ ] **Step 2: 前端 TypeScript 编译**

```bash
cd /Volumes/Dpan/github/water-workspace/water-frontend
npx vue-tsc --noEmit 2>&1 | grep -i "error\|accountLog" | head -10
```

预期：无类型错误。

- [ ] **Step 3: 提交**

```bash
# 后端
cd /Volumes/Dpan/github/water-workspace/water-backend
git add sw-business/sw-business-server/src/main/java/cn/com/emsoft/sw/business/controller/admin/accountingadjust/accountProcess/vo/AccountingAdjustLogPageRespVO.java
git add sw-business/sw-business-server/src/main/java/cn/com/emsoft/sw/business/service/accountingadjust/accountProcess/AccountingAdjustLogProcessServiceImpl.java
git commit -m "feat: add canRecoverBadDebt and fix canRevoke/canRefund/canPrestore logic

- Add canRecoverBadDebt field to AccountingAdjustLogPageRespVO
- Replace hardcoded false with dynamic logic in toPageResp():
  canRevoke = approvalStatus is PENDING_APPROVAL
  canRefund/canPrestore = PREPAID_REFUND + SUCCESS
  canRecoverBadDebt = BAD_DEBT_RECORD + SUCCESS"

# 前端
cd /Volumes/Dpan/github/water-workspace/water-frontend
git add src/api/accountProcess/accountLog/index.ts src/views/accountProcess/accountLog/index.vue
git commit -m "feat: add bad debt recovery button and API to account log page

- Add recoverBadDebt API method calling POST log-recover-bad-debt
- Add canRecoverBadDebt field to AccountingAdjustPageRespVO
- Add recovery button with confirm dialog in function column"
```

## Self-Review

**1. Spec coverage:** 4 个功能按钮全部覆盖：canRevoke/canRefund/canPrestore 修正 + canRecoverBadDebt 新增。

**2. Placeholder scan:** 无占位符，所有步骤含具体代码。

**3. Type consistency:**
- `record.approvalStatus`、`record.resultStatus`、`record.objectType` 均为 `LegacyLogRecord` 内部类字段，已存在于 ServiceImpl
- 前端 `canRecoverBadDebt` 字段同时加入 `AccountingAdjustPageRespVO` 接口和 API 调用
- 后端 `recoverBadDebt` API 接收 `{ adjustmentNo: string }`，与 `AdjustExecuteReqDTO` 匹配
