|
|||
|
|
|
|||
|
|

## 🔍 **问题分析**
|
|||
|
|
|
|||
|
|
### **根本原因**
|
|||
|
|
|
|||
|
|
1. **Jackson 序列化循环引用** ⚠️
|
|||
|
|
- Spring MVC 在序列化响应对象时
|
|||
|
|
- 实体类之间存在双向引用
|
|||
|
|
- Jackson 陷入无限循环
|
|||
|
|
|
|||
|
|
2. **可能的触发点**:
|
|||
|
|
- `FundService.deposit()` 返回 `Map<String, Object>`
|
|||
|
|
- `FundService.withdraw()` 返回 `Map<String, Object>`
|
|||
|
|
- 序列化时遇到循环引用

|
## 🛠️ **修复方案**
|
|||
|
|
|
|||
|
|
### **方案1: 配置 Jackson 序列化规则** ✅
|
|||
|
|
|
|||
|
|
**修改文件**: `application-dev.yml`
|
|||
|
|
|
|||
|
|
**添加配置**:
|
|||
|
|
```yaml
|
|||
|
|
spring:
|
|||
|
|
jackson:
|
|||
|
|
serialization:
|
|||
|
|
write-dates-as-timestamps: false
|
|||
|
|
fail-on-empty-beans: false
|
|||
|
|
deserialization:
|
|||
|
|
fail-on-unknown-properties: false
|
|||
|
|
default-property-inclusion: non_null
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
**作用**:
|
|||
|
|
- ✅ 禁用空 bean 序列化失败
|
|||
|
|
- ✅ 不序列化 null 值
|
|||
|
|
- ✅ 优化日期序列化格式
|
|||
|
|
- ✅ 忽略未知属性

## 🚀 **部署步骤**
|
|||
|
|
|
|||
|
|
### **服务器端操作**
|
|||
|
|
|
|||
|
|
```bash
|
|||
|
|
# 1. SSH 登录服务器
|
|||
|
|
ssh root@8.155.172.147
|
|||
|
|
|
|||
|
|
# 2. 进入项目目录
|
|||
|
|
cd /path/to/monisuo
|
|||
|
|
|
|||
|
|
# 3. 拉取最新代码

|
git pull origin main
|
|||
|
|
|
|||
|
|

|
|||
|
|
|
|||
|
|

## ⚠️ **注意事项**
|
|||
|
|
|
|||
|
|
### **如果问题仍然存在**
|
|||
|
|
|
|||
|
|
1. **查看详细错误日志**
|
|||
|
|
```bash
|
|||
|
|
tail -f /var/log/monisuo/app.log | grep -A 50 StackOverflowError
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
2. **检查实体类**
|
|||
|
|
- 查看是否有双向引用
|
|||
|
|
- 添加 `@JsonIgnore` 注解
|
|||
|
|
|
|||
|
|
3. **临时解决方案**
|
|||
|
|
- 修改实体类，使用 `@Getter` 和 `@Setter` 替代 `@Data`
|
|||
|
|
- 避免自动生成 `toString()` 方法
|
|||
