demo主要以txlcn-demo构建，版本是5.0.2。大致流程为serviceA调用serviceB删除某条数据的方法,该方法是通过JpaRepository的deleteById实现的。serviceA模拟异常发生后，serviceB开始尝试数据补偿，逆向插入删除的那条数据，但是我根据日志和断点发现，补偿的sql语句是正常的，但是参数数组却多了一个参数，其参数值为null，最终无法执行SQL导致补偿失败。 --- 数据库表 ``` CREATE TABLE `tb_description` ( `id` int(11) NOT NULL AUTO_INCREMENT, `user_id` int(11) NOT NULL, `description` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL, PRIMARY KEY (`id`)...

我准备使用Mycat和postgresSQL做数据库集群和读写分离，可以提供一个LCN的例子吗
# SpringCloud Feign 调用服务 1.分布式事务超时：发起者开启分布式事务lcn模式，参与者加入事务，由于参与者方事务没有提交，导致发起者方的feign 调用超时 2.参与者的加入的事务组不存在：发起者发起分布式事务，参与者方出现异常：attempts to join the non-existent transaction group. 发起者均使用事务：@LcnTransaction(propagation = DTXPropagation.REQUIRED) 参与者均使用事务：@LcnTransaction(propagation = DTXPropagation.SUPPORTS) 问题是偶发性的，但是出现几率比较高，麻烦作者解答一下
