# 后端Controller修改提示词

## 🎯 需要修改的文件
`/Users/gxwebsoft/VUE/template-10579/JAVA/mp-java/src/main/java/com/gxwebsoft/credit/controller/CreditMpCustomerController.java`

## 📝 具体修改内容

### 1. 添加新的接口方法

在现有的 `CreditMpCustomerController` 类中添加以下方法：

```java
/**
 * 审核跟进步骤
 */
@PostMapping("/approve-follow-step")
@OperLog(title = "审核跟进步骤", businessType = BusinessType.UPDATE)
public R<Void> approveFollowStep(@RequestBody FollowStepApprovalDTO dto) {
    creditMpCustomerService.approveFollowStep(dto);
    return R.ok();
}

/**
 * 批量审核跟进步骤
 */
@PostMapping("/batch-approve-follow-steps")
@OperLog(title = "批量审核跟进步骤", businessType = BusinessType.UPDATE)
public R<Void> batchApproveFollowSteps(@RequestBody BatchFollowStepApprovalDTO dto) {
    creditMpCustomerService.batchApproveFollowSteps(dto);
    return R.ok();
}

/**
 * 获取待审核的跟进步骤列表
 */
@GetMapping("/pending-approval-steps")
@OperLog(title = "获取待审核跟进步骤", businessType = BusinessType.SELECT)
public R<List<PendingApprovalStepVO>> getPendingApprovalSteps(FollowStepQueryDTO query) {
    List<PendingApprovalStepVO> list = creditMpCustomerService.getPendingApprovalSteps(query);
    return R.ok(list);
}

/**
 * 获取客户跟进统计
 */
@GetMapping("/follow-statistics/{customerId}")
@OperLog(title = "获取客户跟进统计", businessType = BusinessType.SELECT)
public R<FollowStatisticsDTO> getFollowStatistics(@PathVariable Long customerId) {
    FollowStatisticsDTO statistics = creditMpCustomerService.getFollowStatistics(customerId);
    return R.ok(statistics);
}

/**
 * 结束客户跟进流程
 */
@PostMapping("/end-follow-process")
@OperLog(title = "结束客户跟进流程", businessType = BusinessType.UPDATE)
public R<Void> endFollowProcess(@RequestBody EndFollowProcessDTO dto) {
    creditMpCustomerService.endFollowProcess(dto.getCustomerId(), dto.getReason());
    return R.ok();
}
```

### 2. 添加必要的导入

在文件顶部添加以下导入语句：

```java
import com.your.package.dto.FollowStepApprovalDTO;
import com.your.package.dto.BatchFollowStepApprovalDTO;
import com.your.package.dto.FollowStepQueryDTO;
import com.your.package.dto.PendingApprovalStepVO;
import com.your.package.dto.FollowStatisticsDTO;
import com.your.package.dto.EndFollowProcessDTO;
import com.your.package.annotation.OperLog;
import com.your.package.enums.BusinessType;
```

### 3. 需要创建的DTO类

#### FollowStepApprovalDTO.java
```java
@Data
public class FollowStepApprovalDTO {
    private Long customerId;
    private Integer step;
    private Boolean approved;
    private String remark;
}
```

#### BatchFollowStepApprovalDTO.java
```java
@Data
public class BatchFollowStepApprovalDTO {
    private List<FollowStepApprovalDTO> approvals;
}
```

#### FollowStepQueryDTO.java
```java
@Data
public class FollowStepQueryDTO {
    private Integer step;
    private Long customerId;
    private Long userId;
}
```

#### PendingApprovalStepVO.java
```java
@Data
public class PendingApprovalStepVO {
    private Long customerId;
    private String customerName;
    private Integer step;
    private String stepTitle;
    private String submittedAt;
    private String submittedBy;
    private Object content;
}
```

#### FollowStatisticsDTO.java
```java
@Data
public class FollowStatisticsDTO {
    private Integer totalSteps;
    private Integer completedSteps;
    private Integer currentStep;
    private Double progress;
    private List<FollowStepDetailDTO> stepDetails;
}
```

#### FollowStepDetailDTO.java
```java
@Data
public class FollowStepDetailDTO {
    private Integer step;
    private String title;
    private String status; // pending, submitted, approved, rejected
    private String submittedAt;
    private String approvedAt;
}
```

#### EndFollowProcessDTO.java
```java
@Data
public class EndFollowProcessDTO {
    private Long customerId;
    private String reason;
}
```

### 4. Service层需要添加的方法

在 `CreditMpCustomerService` 接口中添加：

```java
/**
 * 审核跟进步骤
 */
void approveFollowStep(FollowStepApprovalDTO dto);

/**
 * 批量审核跟进步骤
 */
void batchApproveFollowSteps(BatchFollowStepApprovalDTO dto);

/**
 * 获取待审核的跟进步骤列表
 */
List<PendingApprovalStepVO> getPendingApprovalSteps(FollowStepQueryDTO query);

/**
 * 获取客户跟进统计
 */
FollowStatisticsDTO getFollowStatistics(Long customerId);

/**
 * 结束客户跟进流程
 */
void endFollowProcess(Long customerId, String reason);
```

### 5. 实体类修改

在 `CreditMpCustomer.java` 中添加第5-7步的字段：

```java
// 第5步字段
private Integer followStep5Submitted;
private String followStep5SubmittedAt;
private String followStep5Contracts;
private Integer followStep5NeedApproval;
private Integer followStep5Approved;
private String followStep5ApprovedAt;
private Long followStep5ApprovedBy;

// 第6步字段
private Integer followStep6Submitted;
private String followStep6SubmittedAt;
private String followStep6PaymentRecords;
private String followStep6ExpectedPayments;
private Integer followStep6NeedApproval;
private Integer followStep6Approved;
private String followStep6ApprovedAt;
private Long followStep6ApprovedBy;

// 第7步字段
private Integer followStep7Submitted;
private String followStep7SubmittedAt;
private String followStep7VisitRecords;
private Integer followStep7NeedApproval;
private Integer followStep7Approved;
private String followStep7ApprovedAt;
private Long followStep7ApprovedBy;

// 流程结束字段
private Integer followProcessEnded;
private String followProcessEndTime;
private String followProcessEndReason;
```

### 6. 数据库修改

执行以下SQL语句：

```sql
-- 第5步字段
ALTER TABLE credit_mp_customer ADD COLUMN follow_step5_submitted TINYINT DEFAULT 0;
ALTER TABLE credit_mp_customer ADD COLUMN follow_step5_submitted_at VARCHAR(255);
ALTER TABLE credit_mp_customer ADD COLUMN follow_step5_contracts TEXT;
ALTER TABLE credit_mp_customer ADD COLUMN follow_step5_need_approval TINYINT DEFAULT 1;
ALTER TABLE credit_mp_customer ADD COLUMN follow_step5_approved TINYINT DEFAULT 0;
ALTER TABLE credit_mp_customer ADD COLUMN follow_step5_approved_at VARCHAR(255);
ALTER TABLE credit_mp_customer ADD COLUMN follow_step5_approved_by BIGINT;

-- 第6步字段
ALTER TABLE credit_mp_customer ADD COLUMN follow_step6_submitted TINYINT DEFAULT 0;
ALTER TABLE credit_mp_customer ADD COLUMN follow_step6_submitted_at VARCHAR(255);
ALTER TABLE credit_mp_customer ADD COLUMN follow_step6_payment_records TEXT;
ALTER TABLE credit_mp_customer ADD COLUMN follow_step6_expected_payments TEXT;
ALTER TABLE credit_mp_customer ADD COLUMN follow_step6_need_approval TINYINT DEFAULT 1;
ALTER TABLE credit_mp_customer ADD COLUMN follow_step6_approved TINYINT DEFAULT 0;
ALTER TABLE credit_mp_customer ADD COLUMN follow_step6_approved_at VARCHAR(255);
ALTER TABLE credit_mp_customer ADD COLUMN follow_step6_approved_by BIGINT;

-- 第7步字段
ALTER TABLE credit_mp_customer ADD COLUMN follow_step7_submitted TINYINT DEFAULT 0;
ALTER TABLE credit_mp_customer ADD COLUMN follow_step7_submitted_at VARCHAR(255);
ALTER TABLE credit_mp_customer ADD COLUMN follow_step7_visit_records TEXT;
ALTER TABLE credit_mp_customer ADD COLUMN follow_step7_need_approval TINYINT DEFAULT 1;
ALTER TABLE credit_mp_customer ADD COLUMN follow_step7_approved TINYINT DEFAULT 0;
ALTER TABLE credit_mp_customer ADD COLUMN follow_step7_approved_at VARCHAR(255);
ALTER TABLE credit_mp_customer ADD COLUMN follow_step7_approved_by BIGINT;

-- 流程结束字段
ALTER TABLE credit_mp_customer ADD COLUMN follow_process_ended TINYINT DEFAULT 0;
ALTER TABLE credit_mp_customer ADD COLUMN follow_process_end_time VARCHAR(255);
ALTER TABLE credit_mp_customer ADD COLUMN follow_process_end_reason TEXT;
```

## 🔧 实施步骤

1. **数据库修改**：先执行SQL脚本添加字段
2. **实体类修改**：更新 `CreditMpCustomer.java`
3. **DTO类创建**：创建所有需要的DTO类
4. **Service接口**：添加方法定义
5. **Service实现**：实现具体业务逻辑
6. **Controller修改**：添加新的接口方法
7. **Mapper修改**：添加必要的SQL查询

## ⚠️ 注意事项

1. **包名替换**：请将 `com.your.package` 替换为实际的包名
2. **注解检查**：确保 `@OperLog` 和 `BusinessType` 存在
3. **事务处理**：审核方法需要添加 `@Transactional` 注解
4. **权限控制**：根据需要添加权限验证注解
5. **数据验证**：在Service层添加必要的数据验证逻辑

## 🧪 测试建议

1. 测试步骤提交和审核流程
2. 测试批量审核功能
3. 测试统计接口返回的数据格式
4. 测试流程结束功能
5. 验证步骤解锁逻辑是否正确

## 📋 完整的业务流程

1. 销售人员提交步骤 → 设置 `submitted=1`, `needApproval=1`
2. 管理员审核 → 设置 `approved=0/1`, 记录审核时间和审核人
3. 前端检查 `approved` 状态决定是否解锁下一步
4. 支持查看待审核列表和批量操作
5. 提供进度统计和流程管理功能
