整合spring-cloud-alibaba-seata引发的惨案
依赖
编写配置类
在项目数据库中创建undo_log表
CREATE TABLE `undo_log` (
`id` bigint(20) NOT NULL AUTO_INCREMENT,
`branch_id` bigint(20) NOT NULL,
`xid` varchar(100) NOT NULL,
`context` varchar(128) NOT NULL,
`rollback_info` longblob NOT NULL,
`log_status` int(11) NOT NULL,
`log_created` datetime NOT NULL,
`log_modified` datetime NOT NULL,
`ext` varchar(100) DEFAULT NULL,
PRIMARY KEY (`id`),
UNIQUE KEY `ux_undo_log` (`xid`,`branch_id`)
) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8;
创建俩个配置文件
- registry.conf
registry {
# file 、nacos 、eureka、redis、zk、consul、etcd3、sofa
type = "file"
#试用默认的文件格式
file {
name = "file.conf"
}
}
config {
# file、nacos 、apollo、zk、consul、etcd3、springCloudConfig
type = "file"
#试用默认的文件格式
file {
name = "file.conf"
}
}
- file.conf
transport {
# tcp udt unix-domain-socket
type = "TCP"
#NIO NATIVE
server = "NIO"
#enable heartbeat
heartbeat = true
# the client batch send request enable
enableClientBatchSendRequest = true
#thread factory for netty
threadFactory {
bossThreadPrefix = "NettyBoss"
workerThreadPrefix = "NettyServerNIOWorker"
serverExecutorThread-prefix = "NettyServerBizHandler"
shareBossWorker = false
clientSelectorThreadPrefix = "NettyClientSelector"
clientSelectorThreadSize = 1
clientWorkerThreadPrefix = "NettyClientWorkerThread"
# netty boss thread size,will not be used for UDT
bossThreadSize = 1
#auto default pin or 8
workerThreadSize = "default"
}
shutdown {
# when destroy server, wait seconds
wait = 3
}
serialization = "seata"
compressor = "none"
}
service {
#transaction service group mapping
vgroupMapping.my_test_tx_group = "default"
#only support when registry.type=file, please don't set multiple addresses
default.grouplist = "192.168.23.160:8091"
#degrade, current not support
enableDegrade = false
#disable seata
disableGlobalTransaction = false
}
client {
rm {
asyncCommitBufferLimit = 10000
lock {
retryInterval = 10
retryTimes = 30
retryPolicyBranchRollbackOnConflict = true
}
reportRetryCount = 5
tableMetaCheckEnable = false
reportSuccessEnable = false
}
tm {
commitRetryCount = 5
rollbackRetryCount = 5
}
undo {
dataValidation = true
logSerialization = "jackson"
logTable = "undo_log"
}
log {
exceptionRate = 100
}
}
最后在yml中配置
spring:
application:
name: user
datasource:
hikari:
username: root
password: 123456
driver-class-name: com.mysql.cj.jdbc.Driver
jdbc-url: jdbc:mysql://localhost:3306/zhuoyue_user?serverTimezone=UTC&characterEncoding=utf8
cloud:
alibaba:
seata:
# 这里要和file.conf文件中一致
tx-service-group: my_test_tx_group
运行seata-server，这里我是在docker上跑
启动项目就一报错
看源码发现没有config.type这个配置字段
通过调试发现在配置里面没有config.type这字段
然后各种检查、最后发现是文件名起错了
晕，要不是不忍心，真想给自己一个大嘴巴子
把文件名改过来后，启动项目，果断成功
这。这这，真滴是大型翻车现场
