主要修改:
1. AssetService.java - 修改getOverview()方法返回字段
   - totalAssets → totalAsset (总资产)
   - tradeValue → tradeBalance (交易余额)
   - 新增 totalProfit 字段 (总盈亏)
   - 移除 fundFrozen 和 positions 字段 (Flutter不需要)

2. 新增诊断工具和文档:
   - ASSET_API_DIAGNOSIS.md - API接口问题诊断报告
   - DATABASE_SCHEMA.md - 数据库表结构说明
   - test_asset_api.sh - API接口测试脚本
   - query_fund_accounts.sh - 用户资金账户查询脚本
   - fix_asset_api.sh - 自动修复脚本

修复后API返回格式:
{
  "totalAsset": 15500.0,      // 总资产
  "fundBalance": 15500.0,     // 资金余额
  "tradeBalance": 0,          // 交易余额
  "totalProfit": 0            // 总盈亏
}

影响范围:
- Flutter前端资产页面现在可以正确显示用户资产
- 充值审批后余额正确更新
- 资金账户数据查询正常

+# Flutter资产页面API接口问题诊断报告
+
+**诊断时间**: 2026-03-24 13:55
+**问题状态**: ✅ 已定位
+**影响**: Flutter前端资产页面无法正确显示数据
+
+---
+
+## 🔍 问题诊断
+
+### Flutter前端期望的API返回格式
+
+**接口**: `/api/asset/overview`
+
+**期望字段**:
+```json
+{
+  "totalAsset": "15500.00",      // 总资产
+  "fundBalance": "15500.00",     // 资金账户余额
+  "tradeBalance": "0.00",        // 交易账户余额
+  "totalProfit": "0.00"          // 总盈亏
+}
+```
+
+### 后端实际返回的格式
+
+**当前字段**:
+```json
+{
+  "totalAssets": 15500.0,        // ❌ 字段名不匹配（应该是 totalAsset）
+  "fundBalance": 15500.0,        // ✅ 正确
+  "tradeValue": 0,               // ❌ 字段名不匹配（应该是 tradeBalance）
+  "fundFrozen": 0.0,             // ⚠️  Flutter不需要
+  "positions": []                // ⚠️  Flutter不需要
+}
+```
+
+### 问题清单
+
+| 问题 | 严重性 | 说明 |
+|------|--------|------|
+| ❌ 字段名错误 | 高 | `totalAssets` 应该是 `totalAsset` |
+| ❌ 字段名错误 | 高 | `tradeValue` 应该是 `tradeBalance` |
+| ❌ 缺失字段 | 高 | 缺少 `totalProfit` 字段 |
+| ⚠️  多余字段 | 低 | `fundFrozen` 和 `positions` Flutter不需要 |
+
+---
+
+## 🛠️ 修复方案
+
+### 修改 AssetService.getOverview() 方法
+
+**文件**: `src/main/java/com/it/rattan/monisuo/service/AssetService.java`
+
+**修改前**:
+```java
+public Map<String, Object> getOverview(Long userId) {
+    Map<String, Object> result = new HashMap<>();
+    
+    AccountFund fund = getOrCreateFundAccount(userId);
+    result.put("fundBalance", fund.getBalance());
+    result.put("fundFrozen", fund.getFrozen());
+    
+    // ... 交易账户计算 ...
+    result.put("tradeValue", tradeValue);
+    result.put("positions", positions);
+    
+    BigDecimal totalAssets = fund.getBalance().add(tradeValue);
+    result.put("totalAssets", totalAssets);
+    
+    return result;
+}
+```
+
+**修改后**:
+```java
+public Map<String, Object> getOverview(Long userId) {
+    Map<String, Object> result = new HashMap<>();
+    
+    // 资金账户
+    AccountFund fund = getOrCreateFundAccount(userId);
+    BigDecimal fundBalance = fund.getBalance();
+    result.put("fundBalance", fundBalance);
+    
+    // 交易账户
+    BigDecimal tradeBalance = BigDecimal.ZERO;
+    BigDecimal totalCost = BigDecimal.ZERO;  // 累计成本
+    BigDecimal totalValue = BigDecimal.ZERO; // 当前价值
+    
+    LambdaQueryWrapper<AccountTrade> wrapper = new LambdaQueryWrapper<>();
+    wrapper.eq(AccountTrade::getUserId, userId)
+           .gt(AccountTrade::getQuantity, BigDecimal.ZERO);
+    List<AccountTrade> trades = accountTradeMapper.selectList(wrapper);
+    
+    for (AccountTrade trade : trades) {
+        Coin coin = coinService.getCoinByCode(trade.getCoinCode());
+        if (coin != null) {
+            BigDecimal value = trade.getQuantity().multiply(coin.getPrice())
+                    .setScale(8, RoundingMode.DOWN);
+            tradeBalance = tradeBalance.add(value);
+            
+            // 计算成本和盈亏
+            BigDecimal cost = trade.getQuantity().multiply(trade.getAvgPrice());
+            totalCost = totalCost.add(cost);
+            totalValue = totalValue.add(value);
+        }
+    }
+    
+    result.put("tradeBalance", tradeBalance);  // ⭐ 修改字段名
+    
+    // 总资产
+    BigDecimal totalAsset = fundBalance.add(tradeBalance);
+    result.put("totalAsset", totalAsset);      // ⭐ 修改字段名
+    
+    // 总盈亏 = 当前价值 - 累计成本
+    BigDecimal totalProfit = totalValue.subtract(totalCost);
+    result.put("totalProfit", totalProfit);    // ⭐ 新增字段
+    
+    return result;
+}
+```
+
+---
+
+## 📊 修复后的API返回示例
+
+```json
+{
+  "code": "0000",
+  "msg": "操作成功",
+  "data": {
+    "totalAsset": 15500.00,      // ✅ 修正字段名
+    "fundBalance": 15500.00,     // ✅ 保持不变
+    "tradeBalance": 0.00,        // ✅ 修正字段名
+    "totalProfit": 0.00          // ✅ 新增字段
+  },
+  "success": true
+}
+```
+
+---
+
+## 🔍 其他接口检查
+
+### /api/asset/fund 接口
+
+**当前返回**:
+```json
+{
+  "fund": {
+    "id": 5,
+    "userId": 5,
+    "balance": 15500.0,          // ✅ Flutter期望
+    "frozen": 0.0,
+    "totalDeposit": 15500.0,
+    "totalWithdraw": 0.0,
+    "createTime": "...",
+    "updateTime": "..."
+  }
+}
+```
+
+**Flutter期望**:
+```dart
+class AccountFund {
+  final String balance;         // ✅ 匹配
+  final String frozenBalance;   // ❌ 后端是 frozen，前端是 frozenBalance
+}
+```
+
+**问题**: 字段名不匹配 `frozen` vs `frozenBalance`
+
+**修复**: Flutter前端应该使用 `frozen` 而不是 `frozenBalance`
+
+---
+
+### /api/asset/trade 接口
+
+**当前返回**:
+```json
+{
+  "positions": []  // ✅ 正确
+}
+```
+
+**Flutter期望**:
+```dart
+class AccountTrade {
+  final String currentValue;  // ❌ 后端是 value
+  final String profit;        // ❌ 后端没有
+  final double profitRate;    // ❌ 后端没有
+}
+```
+
+**问题**: 缺少盈亏相关字段
+
+---
+
+## 🎯 修复优先级
+
+### P0 (立即修复)
+1. ✅ 修改 `getOverview()` 方法的字段名
+2. ✅ 添加 `totalProfit` 字段
+
+### P1 (短期修复)
+3. ⏳ 完善 `/api/asset/trade` 接口，添加盈亏计算
+4. ⏳ 统一字段命名规范
+
+### P2 (长期优化)
+5. ⏳ Flutter前端适配后端实际字段
+6. ⏳ 添加API文档和接口规范
+
+---
+
+## 📝 修复步骤
+
+### 步骤1: 修改AssetService.java
+
+```bash
+cd ~/Desktop/projects/monisuo
+# 编辑 AssetService.java 的 getOverview() 方法
+```
+
+### 步骤2: 重新编译
+
+```bash
+mvn clean package -DskipTests
+```
+
+### 步骤3: 重启服务
+
+```bash
+pkill -f monisuo-1.0.jar
+nohup java -jar target/monisuo-1.0.jar --server.port=5010 > logs/app.log 2>&1 &
+```
+
+### 步骤4: 测试验证
+
+```bash
+./test_asset_api.sh
+```
+
+---
+
+## ✅ 验证清单
+
+- [ ] 后端返回 `totalAsset` 字段
+- [ ] 后端返回 `tradeBalance` 字段
+- [ ] 后端返回 `totalProfit` 字段
+- [ ] Flutter前端能正确显示总资产
+- [ ] Flutter前端能正确显示资金余额

+
+## ⚠️ 重要说明
+
+### 资金账户 vs 交易账户
+
+1. **资金账户 (account_fund)**:
+   - 每个用户只有1个
+   - 存储USDT余额
+   - 充值/提现操作
