浏览器请求调用方服务超时后，数据死锁问题

### 问题描述：
依照下面的代码进行描述，我在调用方服务中设置Thread.sleep(10000)来模拟浏览器调用超时的情况。浏览器请求`controller`，访问调用方服务的`startFlow`方法，第一次请求log如下：
```

```
debug查看到是卡在`mapper.updateById(order);`这里，在mysql执行`SELECT * FROM INFORMATION_SCHEMA.INNODB_TRX;`可以看到这个的update语句出现了lock wait。等大概20秒左右，lock wait消失，页面请求失败。后面页面每次请求都是这个死锁的情况。

### 调用方代码：
```java
@Transactional(rollbackFor = Exception.class)
@Override
@TxTransaction
public com.zhirui.core.model.result.ResultModel startFlow(String id) {
try {
Thread.sleep(10000);
} catch (Exception e) {
e.printStackTrace();
}
List list = listByAll(searchVO);
// 修改单据状态为审核中
PurchasePlanOrder order = new PurchasePlanOrder();
order.setId(id);
order.setApprovalStatus((short) 1);
mapper.updateById(order);
}
```
```java
@Override
@Transactional(propagation = Propagation.NOT_SUPPORTED)
public List listByAll(PurchasePlanOrderSearchVO searchVO) {
searchVO.setTenantId(UserHelper.getTenantId());
List list = mapper.listByAll(searchVO);
return list;
}
```
### 被调用方代码：
```java
@Override
@TxTransaction
@Transactional(rollbackFor = Exception.class)
public FlowInstanceDTO startProcess(Map map, String tenantId) throws Exception {
// 1.构造业务数据
// 获取当前用户
TUser user = UserHelper.getSecUser();
FlowInstance flowInstance = generateFlowInstance(map, user);

// 2.查询流程定义
ProcessDefinition processDefinition = repositoryService.createProcessDefinitionQuery()
.processDefinitionKey(flowInstance.getProcessKey())
.latestVersion().singleResult();
// 省略...
}
