部署seata
1.下載鏡像，啟動容器
docker run -d --name seata-server -p 8091:8091 seataio/seata-server:1.6.1
2.復制容器中的配置文件夾
docker cp seata-server:/seata-server/resources D:/seata-server
3.新建數據庫
mysql腳本
CREATE TABLE IF NOT EXISTS `global_table`

INSERT INTO `distributed_lock` (lock_key, lock_value, expire) VALUES ('RetryRollbacking', ' ', 0);
INSERT INTO `distributed_lock` (lock_key, lock_value, expire) VALUES ('TxTimeoutCheck', ' ', 0);
4.修改application.yml
將application.example.yml內容根據需要粘貼進application.yml并調整
nacos，mysql，seata的ip同為192.168.2.178
server:
? port: 7091
spring:
? application:
? ? name: seata-server
logging:
? config: classpath:logback-spring.xml
? file:
? ? path: ${user.home}/logs/seata
? extend:
? ? logstash-appender:
? ? ? destination: 127.0.0.1:4560
? ? kafka-appender:
? ? ? bootstrap-servers: 127.0.0.1:9092
? ? ? topic: logback_to_logstash

? ? ? username:

? ? ignore:
? ? ? urls: /,/**/*.css,/**/*.js,/**/*.html,/**/*.map,/**/*.svg,/**/*.png,/**/*.ico,/console-fe/public/**,/api/v1/auth/login
5.刪除原容器，使用修改后的配置重啟容器
docker run -d --name seata-server -p 8091:8091 -p 7091:7091 -v D:\seata-server\resources\resources:/seata-server/resources -e SEATA_IP=192.168.2.178 seataio/seata-server:1.6.1
seata啟動成功，查看頁面
http://192.168.2.178:7091/
springcloud集成
1.引入maven依賴
<dependency> <artifactId>seata-spring-boot-starter</artifactId> <groupId>io.seata</groupId> <version>1.6.1</version></dependency><dependency> <groupId>com.alibaba.cloud</groupId> <artifactId>spring-cloud-starter-alibaba-seata</artifactId> <version>2022.0.0.0</version> <exclusions> <!--自帶1.7.0 改為1.6.1--> <exclusion> <artifactId>seata-spring-boot-starter</artifactId> <groupId>io.seata</groupId> </exclusion> </exclusions></dependency>
2.添加配置
seata:
enabled:true
? application-id : ${spring.application.name}
tx-service-group: default_tx_group
use-jdk-proxy:true
? enable-auto-data-source-proxy:true
? registry:
type:nacos
? ? nacos:
application: seata-server
server-addr: 192.168.2.178:8848
group: SEATA_GROUP
config:
type:nacos
? ? nacos:
server-addr: 192.168.2.178:8848
group: SEATA_GROUP
service:
vgroupMapping:
default_tx_group: default
3.應用服務數據庫添加undo_log表
CREATE TABLE `undo_log` (
? `id` bigint NOT NULL AUTO_INCREMENT,
? `branch_id` bigint NOT NULL,
? `xid` varchar(100) NOT NULL,
? `context` varchar(128) NOT NULL,
? `rollback_info` longblob NOT NULL,
? `log_status` int 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 DEFAULT CHARSET=utf8mb3;
4.方法加注解@GlobalTransactional
@GlobalTransactional
@Transactional
public void test(){
。。。
}
5.nacos創建配置service.vgroupMapping.default_tx_group = default
Data ID：service.vgroupMapping.default_tx_group
Group：SEATA_GROUP
配置格式：TEXT
配置內容：default
6.啟動服務，完事
遇到的問題
1.can not get cluster name in registry config 'service.vgroupMapping.default_tx_group'
服務啟動報錯can not get cluster name in registry config 'service.vgroupMapping.default_tx_group', please make sure registry config correct
未配置事務組，按照上述步驟添加配置service.vgroupMapping.default_tx_group即可
2.0101 can not connect to 10.200.4.68:8091 cause:can not register RM,err:can not connect to services-server.
nacos注冊中心中的ip為docker容器ip，需改為宿主機ip，啟動容器添加參數-e SEATA_IP=XXX
3.分布式事務失效
沒和springcloud組件集成
除seata-spring-boot-starter外，需完整引入spring-cloud-starter-alibaba-seata
