+}
+```
+
+**响应:**
+```json
+{
+  "msg": "保存成功",
+  "code": 200
+}
+```
+
+**状态:** ✅ 通过
+
+---
+
+### 5. 数据库验证
+
+#### 5.1 第一次更新验证
+
+**SQL:**
+```sql
+SELECT param_value, update_by, update_time
+FROM ccdi_model_param
+WHERE model_code = 'LARGE_TRANSACTION'
+  AND param_code = 'SINGLE_TRANSACTION_AMOUNT';
+```
+
+**结果:**
+| param_value | update_by | update_time |
+|-------------|-----------|-------------|
+| 60000 | admin | 2026-02-25 18:03:10 |
+
+**验证点:**
+- ✅ param_value 已更新为 60000
+- ✅ update_by 有值 (admin)
+- ✅ update_time 有值
+
+**状态:** ✅ 通过
+
+---
+
+### 6. 安全性验证
+
+#### 6.1 尝试修改其他字段
+
+**请求:**
+```json
+{
+  "projectId": 0,
+  "modelCode": "LARGE_TRANSACTION",
+  "modelName": "大额交易模型(恶意修改)",
+  "params": [
+    {
+      "paramCode": "SINGLE_TRANSACTION_AMOUNT",
+      "paramName": "单笔交易额(恶意修改)",
+      "paramDesc": "恶意修改描述",
+      "paramValue": "70000",
+      "paramUnit": "美元",
+      "sortOrder": 99
+    }
+  ]
+}
+```
+
+**数据库验证结果:**
+| 字段 | 预期值 | 实际值 | 结果 |
+|------|--------|--------|------|
+| param_name | 单笔交易额 | 单笔交易额 | ✅ 未被修改 |
+| param_desc | 单笔超过该金额视为大额交易 | 单笔超过该金额视为大额交易 | ✅ 未被修改 |
+| param_value | 70000 | 70000 | ✅ 正确更新 |
+| param_unit | 元 | 元 | ✅ 未被修改 |
+| sort_order | 1 | 1 | ✅ 未被修改 |
+| update_by | admin | admin | ✅ 有值 |
+| update_time | 有值 | 2026-02-25 18:03:33 | ✅ 有值 |
+
+**结论:**
+- ✅ 只有 param_value 字段被更新
+- ✅ 其他字段(param_name、param_desc、param_unit、sort_order)保持不变
+- ✅ 安全性验证通过
+
+**状态:** ✅ 通过
+
+---
+
+## 接口汇总
+
+| 序号 | 接口 | 方法 | 路径 | 状态 |
+|------|------|------|------|------|
+| 1 | 登录获取Token | POST | /login/test | ✅ 通过 |
+| 2 | 查询模型列表 | GET | /ccdi/modelParam/modelList | ✅ 通过 |
+| 3 | 查询模型参数(大额交易) | GET | /ccdi/modelParam/list?modelCode=LARGE_TRANSACTION | ✅ 通过 |
+| 4 | 查询模型参数(外汇交易) | GET | /ccdi/modelParam/list?modelCode=SUSPICIOUS_FOREIGN_EXCHANGE | ✅ 通过 |
+| 5 | 查询模型参数(兼职) | GET | /ccdi/modelParam/list?modelCode=SUSPICIOUS_PART_TIME | ✅ 通过 |
+| 6 | 保存参数配置 | POST | /ccdi/modelParam/save | ✅ 通过 |
+
+---
+
+## 测试统计
+
+- **通过:** 9 个测试
+- **失败:** 0 个测试
+- **总计:** 9 个测试
+
+---
+
+## 结论
+
+✅ **所有测试通过**
+
+后端功能完全符合预期:
+1. 所有接口响应正常
+2. 数据库更新正确
+3. 审计字段自动填充
+4. 安全性验证通过(只更新 param_value 字段)
+5. 三种模型的参数查询均返回正确数据
+
