Spring Cloud Alibaba之集成seata1.4.2+nacos（docker部署）
一、前提版本说明：
1、springboot版本pom
org.springframework.boot
spring-boot-starter-parent
2.2.4.RELEASE
2、nacos版本
2.1、server版本：1.4.0 ps：我用的比较老 反正没有出现什么问题
2.2、client项目引入：
<--项目从nacos动态读取配置需要引入-->
com.alibaba.cloud
spring-cloud-starter-alibaba-nacos-config
2.2.6.RELEASE
<--项目注册到nacos需要引入-->
com.alibaba.cloud
spring-cloud-starter-alibaba-nacos-discovery
2.2.6.RELEASE
3、seata版本
3.1、seata 服务端版本：1.4.2
3.2、client项目引入：
com.alibaba.cloud
spring-cloud-starter-alibaba-seata
2.2.6.RELEASE
4、spring-cloud-alibaba 版本 各个对应版本
https://github.com/alibaba/spring-cloud-alibaba/wiki/%E7%89%88%E6%9C%AC%E8%AF%B4%E6%98%8E
二、进入正文
安装nacos
进入服务器 使用 ：docker安装 seata
安装步骤：
1、使用docker 拉取 seata 镜像
docker pull seataio/seata-server:1.4.2 2、启动镜像：
docker run -d --name seata-server -e SEATA_IP=39.xx.xx.xx -e SEATA_PORT=8091 -p 8091:8091 seataio/seata-server:1.4.2ps：
--name seata-server 注册到nacos的话，服务名称就是seata-server，个人理解相当于springboot 配置中的（spring.application.name=product）欢迎指正。
SEATA_IP=39.xx.xx.xx 服务器的外网ip
-e SEATA_PORT=8091 seata的服务端口
-p 8091:8091 宿主机与容器的端口映射
3、查看运行容器
docker ps
红色框内 container id 后面拷贝会用到
ps：如果出现seata-server 代表启动成功
4、修改seata配置文件
4.1、拷贝容器内文件file.conf到容器外的/usr/local/seata径下
docker cp 2177b74a2b84:/seata-server/resources/file.conf /usr/local/seata/file.conf 4.2、拷贝容器内文件registry.conf到容器外的/usr/local/seata径下
docker cp 2177b74a2b84:/seata-server/resources/registry.conf /usr/local/seata/registry.confps:将 seata的两个配置文件复制到宿主机文件里面-便于更改
4.3、进入 /usr/local/seata文件夹
cd /usr/local/seata
5、更改 registry.conf 重点！！！是1.4.2版本更新的新东西（下面有需要修改的内容以及，各个属性的说明。我真是贴心.....）
5.1、registry.conf文件全部内容：
registry {
# file 、nacos 、eureka、redis、zk、consul、etcd3、sofa
type = "nacos"
nacos {
application = "seata-server"
serverAddr = "xx.xx.xx.xx:8848"
group = "test"
namespace = "57b60655-ab37-48dd-9ab7-xx3c28aa8ab4"
cluster = "default"
username = "nacos"
password = "nacos"
}
eureka {
serviceUrl = "http://localhost:8761/eureka"
application = "default"
weight = "1"
}
redis {
serverAddr = "localhost:6379"
db = 0
password = ""
cluster = "default"
timeout = 0
}
zk {
cluster = "default"
serverAddr = "127.0.0.1:2181"
sessionTimeout = 6000
connectTimeout = 2000
username = ""
password = ""
}
consul {
cluster = "default"
serverAddr = "127.0.0.1:8500"
aclToken = ""
}
etcd3 {
cluster = "default"
serverAddr = "http://localhost:2379"
}
sofa {
serverAddr = "127.0.0.1:9603"
application = "default"
region = "DEFAULT_ZONE"
datacenter = "DefaultDataCenter"
cluster = "default"
group = "SEATA_GROUP"
addressWaitTime = "3000"
}
file {
name = "file.conf"
}
}
config {
# file、nacos 、apollo、zk、consul、etcd3
type = "nacos"
nacos {
serverAddr = "xx.xx.xx.xx:8848"
namespace = "57b60655-ab37-48dd-9ab7-xx3c28aa8ab4"
group = "test"
username = "nacos"
password = "nacos"
dataId = "seataServer.properties"
}
consul {
serverAddr = "127.0.0.1:8500"
aclToken = ""
}
apollo {
appId = "seata-server"
## apolloConfigService will cover apolloMeta
apolloMeta = "http://192.168.1.204:8801"
apolloConfigService = "http://192.168.1.204:8080"
namespace = "application"
apolloAccesskeySecret = ""
cluster = "seata"
}
zk {
serverAddr = "127.0.0.1:2181"
sessionTimeout = 6000
connectTimeout = 2000
username = ""
password = ""
nodePath = "/seata/seata.properties"
}
etcd3 {
serverAddr = "http://localhost:2379"
}
file {
name = "file.conf"
}
}
registry.conf文件第一部分修改内容 registry.nacos属性说明：
registry.type =nacos 意思是将服务注册到nacos（registry.type指定nacos后就只设置registry.nacos中的属性就好了）
registry.nacos.application= "seata-server" seata在nacos中的服务名称
registry.nacos.serverAddr= ""xx.xx.xx.xx:8848" nacos的访问地址|端口
registry.nacos.group= "test" 下面有图
registry.nacos. namespace = "57b60655-ab37-48dd-9ab7-xxxc28aa8ab4" 下面有图
registry.nacos. cluster = "default" 默认就好了
registry.nacos.username = "nacos" nacos的登录账号
registry.nacos. password = "nacos" nacos的登录密码
---------------------------------------------------------------------------------------------------------------------
registry.conf文件第二部分修改内容 属性说明
config.type ="nacos" seata的配置从nacos读取，config.type ="nacos" 那就只设置config.nacos中的属性就好了
其他 参考registry.nacos (步骤5.1) 中的nacos配置
group = "test"
namespace = "57b60655-ab37-48dd-9ab7-853c28aa8ab4"
dataId = "seataServer.properties" 这个很重要
上面所有配置总结意思为：从nacos中 分组group = "test" ； 命名空间namespace = "57b60655-ab37-48dd-9ab7-853c28aa8ab4" seataServer.properties 文件中读取配置
6、
-----------------------------------------------------------
7、将修改好的文件复制回docker容器内
docker cp file.conf 2177b74a2b84:/seata-server/resources/file.conf
docker cp registry.conf 2177b74a2b84:/seata-server/resources/registry.conf8、上传seata配置文件到nacos上传配置
这一步的目的说明：
docker中运行的 seata-server 会从nacos中读取配置 ，如果想修改seata的配置就从nacos修改，为了方便
创建配置时要与registry.conf文件中的
----------重点-------------
registry.conf.group = "test"；
registry.conf.namespace = ""57b60655-ab37-48dd-9ab7-xx3c28aa8ab4""；
dataId = "seataServer.properties"
值一定要 一 一对应起来
----------重点-------------
8.1、nacos和seata配置文件说明
8.2、seataServer.properties配置
1、打开nacos界面新建配置文件
2、创建 seataServer.properties

这几个配置分别对应不同的项目环境使用的事务组；配置内容很重要
---------------------------------------------其他字段说明------------------------------------------------------------
store.mode=db 意思是 seata在使用过程中开启事务时会产生临时数据以及回滚数据 使用数据库保存（ 设置了 store.mode=db之后 只设置store.db的属性就可以了）
store.db.datasource = "druid"
store.db.dbType = "mysql"
store.db. driverClassName = "com.mysql.cj.jdbc.Driver"
store.db.url = "jdbc:mysql://xx.xx.xx.xx:3306/seata?useSSL=true&serverTimezone=GMT"
xx.xx.xx.xx:3306/seata 替换成自己的数据库路径
store.db.user = "seata" 数据库账号
store.db. password = "seata" 数据库密码
其他的根据需要更改.......
注意：
我使用的数据库是mysql8如果使用mysql5的话 改成的对应的
mysql8： store.db. driverClassName = "com.mysql.cj.jdbc.Driver"
mysql5： store.db. driverClassName = "com.mysql.jdbc.Driver"

9、重启 seata
docker restart 2177b74a2b8410、创建表
10.1、将你在file.conf的中设置的数据库中创建3张表
CREATE TABLE `lock_table` (
`row_key` varchar(128) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL,
`xid` varchar(96) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL,
`transaction_id` mediumtext CHARACTER SET utf8 COLLATE utf8_general_ci NULL,

`gmt_modified` datetime(0) NULL DEFAULT NULL,
PRIMARY KEY (`row_key`) USING BTREE
) ENGINE = InnoDB CHARACTER SET = utf8 COLLATE = utf8_general_ci COMMENT = '存储锁表' ROW_FORMAT = Dynamic;
CREATE TABLE `global_table` (
`xid` varchar(128) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL,
`transaction_id` bigint(20) NULL DEFAULT NULL,

PRIMARY KEY (`xid`) USING BTREE,
INDEX `idx_gmt_modified_status`(`gmt_modified`, `status`) USING BTREE,
INDEX `idx_transaction_id`(`transaction_id`) USING BTREE
) ENGINE = InnoDB CHARACTER SET = utf8 COLLATE = utf8_general_ci COMMENT = '分支事务表' ROW_FORMAT = Dynamic;
CREATE TABLE `branch_table` (
`branch_id` bigint(20) NOT NULL,
`xid` varchar(128) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL,
`transaction_id` bigint(20) NULL DEFAULT NULL,

PRIMARY KEY (`branch_id`) USING BTREE,
INDEX `idx_xid`(`xid`) USING BTREE
) ENGINE = InnoDB CHARACTER SET = utf8 COLLATE = utf8_general_ci COMMENT = '全局事务表' ROW_FORMAT = Dynamic;10.2在你项目里连接的数据库中创建一张表
CREATE TABLE `undo_log` (
`id` bigint(20) NOT NULL AUTO_INCREMENT,
`branch_id` bigint(20) NOT NULL,
`xid` varchar(100) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL,
`context` varchar(128) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL,
`rollback_info` longblob NOT NULL,
`log_status` int(11) NOT NULL,
`log_created` datetime(0) NOT NULL,
`log_modified` datetime(0) NOT NULL,
`ext` varchar(100) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL,
PRIMARY KEY (`id`) USING BTREE,
UNIQUE INDEX `ux_undo_log`(`xid`, `branch_id`) USING BTREE
) ENGINE = InnoDB AUTO_INCREMENT = 5 CHARACTER SET = utf8 COLLATE = utf8_general_ci ROW_FORMAT = Dynamic;三、项目内配置文件：
1、yml配置
这是application-dev.yml
seata.service.vgroupMapping.default_tx_group: default seata.tx-service-group: default_tx_group 必须是一个值 如果uat环境可以更改值--前提必须 seataServer.properties 文件内有这个值（8.3步骤后面红色说明！） seata.service.vgroupMapping.uat_tx_group: default seata.tx-service-group: uat_tx_group
#分布式事务 seata 配置
seata:
service:
vgroupMapping:
default_tx_group: default #default_tx_group分组名称必须要跟tx-service-group的值一样
#指定事务分组 分组必须在 nacos seataServer.properties配置中有
tx-service-group: default_tx_group
config:
type: nacos
nacos:
#nacos地址
serverAddr: xx.xx.xx.xx:8848
group: test
namespace: 57b60655-ab37-48dd-9ab7-853c28aa8ab4
userName: nacos
password: nacos
#读取配置文件的 dataId 重要！！！！
dataId: "seataServer.properties"
registry:
type: nacos
nacos:
application: seata-server
server-addr: xx.xx.xx.xx:8848
group: test
namespace: 57b60655-ab37-48dd-9ab7-853c28aa8ab4
userName: nacos
password: nacos2、@GlobalTransactional 添加注解开启事务
@RestController
@RequestMapping("/locationTest")
public class LocationTest {
@RequestMapping("/testEmail")
@UnLogin
@GlobalTransactional
public int testEmail() {
System.out.println(1);
return 1;
}
}3、测试事务开启
4、docker内seata日志文件打印正常
查看日志命令:docker logs 2177b74a2b84(容器id-container Id)
5、数据库配置的全局事务id保存
