+# 出库单经销商验证功能更新
+
+## 修改概述
+
+在 `DeliveryMainServiceImpl` 中的 `addDelivery` 和 `updateDelivery` 方法中添加了经销商一致性验证逻辑，确保出库单中的经销商与关联订单中的经销商保持一致。
+
+## 修改内容
+
+### 1. 新增自定义异常类
+
+创建了 `DealerMismatchException` 异常类，用于处理经销商不匹配的情况：
+
+```java
+public class DealerMismatchException extends RuntimeException {
+    public DealerMismatchException(String message) {
+        super(message);
+    }
+    
+    public DealerMismatchException(String message, Throwable cause) {
+        super(message, cause);
+    }
+}
+```
+
+### 2. 新增验证方法
+
+在 `DeliveryMainServiceImpl` 中添加了 `validateDealerConsistency` 私有方法：
+
+```java
+private void validateDealerConsistency(String orderNo, String deliveryDealerCode) {
+    // 根据订单编号查询订单信息
+    OrderMain order = orderMainMapper.selectByOrderNo(orderNo);
+    if (order == null) {
+        throw new IllegalArgumentException("关联的订单不存在");
+    }
+
+    // 比较经销商编码
+    if (!deliveryDealerCode.equals(order.getDealerCode())) {
+        String errorMessage = String.format(
+            "出库单中的经销商编码[%s]与关联订单[%s]中的经销商编码[%s]不一致",
+            deliveryDealerCode, orderNo, order.getDealerCode()
+        );
+        throw new DealerMismatchException(errorMessage);
+    }
+}
+```
+
+### 3. 修改addDelivery方法
+
+在 `addDelivery` 方法中添加了经销商验证逻辑：
+
+```java
+// 验证出库单中的经销商与关联订单中的经销商是否一致
+validateDealerConsistency(addReq.getOrderNo(), addReq.getDealerCode());
+```
+
+### 4. 修改updateDelivery方法
+
+在 `updateDelivery` 方法中添加了经销商验证逻辑：
+
+```java
+// 验证出库单中的经销商与关联订单中的经销商是否一致
+validateDealerConsistency(updateReq.getOrderNo(), updateReq.getDealerCode());
+```
+
+## 验证逻辑说明
+
+### 验证流程
+
+1. **订单存在性验证**：首先验证关联的订单编号是否在订单管理中存在
+2. **经销商一致性验证**：验证出库单中的经销商编码与关联订单中的经销商编码是否一致
+3. **异常处理**：如果经销商不一致，抛出 `DealerMismatchException` 异常
+
+### 验证时机
+
+- **新增出库单时**：在 `addDelivery` 方法中，在订单存在性验证之后立即进行经销商验证
+- **修改出库单时**：在 `updateDelivery` 方法中，在订单存在性验证之后立即进行经销商验证
+
+### 异常信息
+
+当经销商不一致时，会抛出包含详细信息的异常：
+
+```
+出库单中的经销商编码[DEALER002]与关联订单[ORDER001]中的经销商编码[DEALER001]不一致
+```
+
+## 测试
+
+### 单元测试
+
+创建了 `DeliveryMainServiceImplDealerValidationTest` 测试类，包含以下测试用例：
+
+1. **成功场景测试**：
+   - 经销商一致时的正常流程
+   - 验证方法调用正确性
+
+2. **异常场景测试**：
+   - 经销商不一致时抛出 `DealerMismatchException`
+   - 订单不存在时抛出 `IllegalArgumentException`
+
+3. **异常消息测试**：
+   - 验证异常消息格式的正确性
+

+    if (order == null) {
+        throw new IllegalArgumentException("关联的订单不存在");
+    }
+
+    // 比较经销商编码
+    if (!invoiceDealerCode.equals(order.getDealerCode())) {
+        String errorMessage = String.format(
+            "发票中的经销商编码[%s]与关联订单[%s]中的经销商编码[%s]不一致",
+            invoiceDealerCode, orderNo, order.getDealerCode()
+        );
+        throw new InvoiceValidationException(errorMessage);
+    }
+}
+```
+
+#### validateDeliveryConsistency方法
+```java
+private void validateDeliveryConsistency(String deliveryNo, String invoiceDealerCode) {

+    if (delivery == null) {
+        throw new IllegalArgumentException("关联的出库单不存在");
+    }
+
+    // 比较经销商编码
+    if (!invoiceDealerCode.equals(delivery.getDealerCode())) {
+        String errorMessage = String.format(
+            "发票中的经销商编码[%s]与关联出库单[%s]中的经销商编码[%s]不一致",
+            invoiceDealerCode, deliveryNo, delivery.getDealerCode()

+        throw new InvoiceValidationException(errorMessage);
+    }
+}
+```
+
+### 4. 修改addInvoice方法
+
+在 `addInvoice` 方法中添加了验证逻辑：
+
+```java
+// 验证关联的订单是否存在且经销商一致
+validateOrderConsistency(addReq.getOrderNo(), addReq.getDealerCode());
+
+// 验证关联的出库单是否存在且经销商一致（如果提供了出库单号）
+if (StringUtils.hasText(addReq.getDeliveryNo())) {
+    validateDeliveryConsistency(addReq.getDeliveryNo(), addReq.getDealerCode());
+}
+```
+
+### 5. 修改updateInvoice方法
+
+在 `updateInvoice` 方法中添加了验证逻辑：
+
+```java
+// 验证关联的订单是否存在且经销商一致
+validateOrderConsistency(updateReq.getOrderNo(), updateReq.getDealerCode());
+
+// 验证关联的出库单是否存在且经销商一致（如果提供了出库单号）
+if (StringUtils.hasText(updateReq.getDeliveryNo())) {
+    validateDeliveryConsistency(updateReq.getDeliveryNo(), updateReq.getDealerCode());
+}
+```
+
+## 验证逻辑说明
+
+### 验证流程

+本示例展示了出库单经销商验证功能的工作方式，包括成功场景和失败场景。
+
+## 成功场景
+
+### 场景1：经销商信息一致
+
+**输入数据：**
+- 订单编号：`ORDER001`
+- 订单中的经销商编码：`DEALER001`
+- 出库单中的经销商编码：`DEALER001`
+
+**验证结果：** ✅ 通过验证，继续执行出库单创建/修改流程
+
+**代码示例：**
+```java
+// 订单信息
+OrderMain order = new OrderMain();
+order.setOrderNo("ORDER001");
+order.setDealerCode("DEALER001");
+
+// 出库单请求
+DeliveryAddReq addReq = new DeliveryAddReq();
+addReq.setOrderNo("ORDER001");
+addReq.setDealerCode("DEALER001");
+
+// 验证通过，继续执行
+deliveryMainService.addDelivery(addReq);
+```
+
+## 失败场景
+
+### 场景2：经销商信息不一致
+
+**输入数据：**
+- 订单编号：`ORDER001`
+- 订单中的经销商编码：`DEALER001`
+- 出库单中的经销商编码：`DEALER002`
+
+**验证结果：** ❌ 验证失败，抛出 `DealerMismatchException`
+
+**异常信息：**
+```
+出库单中的经销商编码[DEALER002]与关联订单[ORDER001]中的经销商编码[DEALER001]不一致
+```
+
+**代码示例：**
+```java
+// 订单信息
+OrderMain order = new OrderMain();
+order.setOrderNo("ORDER001");
+order.setDealerCode("DEALER001");
+
+// 出库单请求（经销商编码不匹配）
+DeliveryAddReq addReq = new DeliveryAddReq();
+addReq.setOrderNo("ORDER001");
+addReq.setDealerCode("DEALER002"); // 不匹配的经销商编码
+
+// 验证失败，抛出异常
+try {
+    deliveryMainService.addDelivery(addReq);
+} catch (DealerMismatchException e) {
+    System.out.println("验证失败：" + e.getMessage());
+    // 输出：验证失败：出库单中的经销商编码[DEALER002]与关联订单[ORDER001]中的经销商编码[DEALER001]不一致
+}
+```
+
+### 场景3：关联订单不存在
+
+**输入数据：**
+- 订单编号：`ORDER999`（不存在的订单）
+- 出库单中的经销商编码：`DEALER001`
+
+**验证结果：** ❌ 验证失败，抛出 `IllegalArgumentException`
+
+**异常信息：**
+```
+关联的订单不存在
+```
+
+**代码示例：**
+```java
+// 出库单请求（关联不存在的订单）
+DeliveryAddReq addReq = new DeliveryAddReq();
+addReq.setOrderNo("ORDER999"); // 不存在的订单
+addReq.setDealerCode("DEALER001");
+
+// 验证失败，抛出异常
+try {
+    deliveryMainService.addDelivery(addReq);
+} catch (IllegalArgumentException e) {
+    System.out.println("验证失败：" + e.getMessage());
+    // 输出：验证失败：关联的订单不存在
+}
+```
+
+## API调用示例
+
+### 新增出库单
+
+**请求：**
+```http
+POST /api/delivery/add
+Content-Type: application/json
+
+{
+    "deliveryNo": "DELIVERY001",

+Content-Type: application/json
+
+{
+    "code": 400,
+    "message": "出库单中的经销商编码[DEALER002]与关联订单[ORDER001]中的经销商编码[DEALER001]不一致",
+    "timestamp": "2024-01-15T10:00:00"
+}
+```
+

+}
+```
+
+## 前端处理示例
+
+### JavaScript错误处理
+
+```javascript
+// 新增出库单
+async function addDelivery(deliveryData) {
+    try {
+        const response = await fetch('/api/delivery/add', {
+            method: 'POST',
+            headers: {
+                'Content-Type': 'application/json'
+            },
+            body: JSON.stringify(deliveryData)
+        });
+        
+        if (!response.ok) {
+            const errorData = await response.json();
+            throw new Error(errorData.message);
+        }
+        
+        const result = await response.json();
+        console.log('出库单创建成功', result);
+        
+    } catch (error) {
+        if (error.message.includes('经销商编码') && error.message.includes('不一致')) {
+            // 处理经销商不匹配错误
+            alert('错误：出库单中的经销商与关联订单中的经销商不一致，请检查经销商信息');
+        } else if (error.message.includes('关联的订单不存在')) {
+            // 处理订单不存在错误
+            alert('错误：关联的订单不存在，请检查订单编号');
+        } else {
+            // 处理其他错误
+            alert('出库单创建失败：' + error.message);
+        }
+    }
+}
+```
+
+## 最佳实践
+
+### 1. 数据录入时验证
+
+在用户录入出库单信息时，可以实时验证经销商信息：
+
+```javascript
+// 当订单编号改变时，自动填充经销商信息
+async function onOrderNoChange(orderNo) {
+    if (orderNo) {
+        try {
+            const order = await getOrderByNo(orderNo);
+            if (order) {
+                // 自动填充经销商信息
+                document.getElementById('dealerCode').value = order.dealerCode;
+                document.getElementById('dealerName').value = order.dealerName;
+            }
+        } catch (error) {
+            console.error('获取订单信息失败', error);
+        }
+    }
+}
+```
+
+### 2. 表单验证
+
+在提交前进行客户端验证：
+
+```javascript
+function validateDeliveryForm() {
+    const orderNo = document.getElementById('orderNo').value;
+    const dealerCode = document.getElementById('dealerCode').value;
+    
+    if (orderNo && dealerCode) {
+        // 可以调用API验证经销商一致性
+        return validateDealerConsistency(orderNo, dealerCode);
+    }
+    
+    return true;
+}
+```
+
+### 3. 错误提示优化
+
+提供更友好的错误提示：
+
+```javascript
+function handleDealerValidationError(error) {
+    const errorMessage = error.message;
+    
+    if (errorMessage.includes('经销商编码') && errorMessage.includes('不一致')) {
+        return {
+            type: 'warning',
+            title: '经销商信息不匹配',
+            message: '出库单中的经销商与关联订单中的经销商不一致，请确认经销商信息是否正确',
+            action: '请检查并修正经销商编码'
+        };
+    }
+    
+    return {
+        type: 'error',
+        title: '验证失败',
+        message: errorMessage
+    };
+}
+```

+### 4. 数据联动
+
+实现订单、出库单、发票之间的数据联动：
+
+```javascript
+// 根据订单自动填充相关信息
+async function loadOrderInfo(orderNo) {
+    try {
+        const order = await getOrderByNo(orderNo);
+        if (order) {
+            // 填充经销商信息
+            document.getElementById('dealerCode').value = order.dealerCode;
+            document.getElementById('dealerName').value = order.dealerName;
+            
+            // 加载相关的出库单列表
+            const deliveries = await getDeliveriesByOrderNo(orderNo);
+            updateDeliveryOptions(deliveries);
+        }
+    } catch (error) {
+        console.error('加载订单信息失败', error);
+    }
+}
+
+// 根据出库单自动填充相关信息
+async function loadDeliveryInfo(deliveryNo) {
+    try {
+        const delivery = await getDeliveryByNo(deliveryNo);
+        if (delivery) {
+            // 验证经销商信息是否一致
+            const currentDealerCode = document.getElementById('dealerCode').value;
+            if (currentDealerCode && currentDealerCode !== delivery.dealerCode) {
+                showWarning('出库单中的经销商与当前选择的经销商不一致');
+            }
+        }
+    } catch (error) {
+        console.error('加载出库单信息失败', error);
+    }
+}
+```
