+# fix: 餐厅JSON字段空字符串导致保存报错
+
+- **日期**: 2026-04-01
+- **PR**: #100
+- **影响服务**: hl-resource-service
+
+## 变更内容
+
+### 后端修复（无接口变更）
+
+1. **餐厅保存约束违反修复**：编辑餐厅时 `featured_menu`、`feature_intro`、`arrangement` 等JSON类型字段传空字符串，MySQL JSON列不接受空字符串报错。空字符串统一转为null处理
+2. **修复范围**：创建和更新方法的3个JSON字符串字段同步修复
+
+## 前端影响
+
+**无**。纯后端防御性修复，无接口变更。修复后编辑餐厅位置信息不再报错。
