记录seata做分布式事务时出现多线程同时开启分布式事务出现的错误
遇到的问题就是：在做秒杀系统的过程中，使用了async异步处理秒杀请求，并自定义了线程池，然后使用seata保证分布式事务事务完整性，但是在jemeter测试的过程中出现了以下的错误：
org.springframework.jdbc.UncategorizedSQLException:
### Error updating database. Cause: java.sql.SQLException: io.seata.core.exception.TransactionException: Response[TransactionException[Global lock acquire failed xid = 172.16.0.4:8091:44784376260608000 branchId = 44784382824693760]]

注意查看server端的设定：
