seata加入nacos配置：

1. 首先下載seata安裝包：Release v1.7.0(Not Apache release) · apache/incubator-seata · GitHub
2. 然后解壓，修改配置文件

打開conf/application.yml進(jìn)行修改，重點(diǎn)修改nacos部分配置

server:port: 7091spring:application:name: seata-serverlogging:config: classpath:logback-spring.xmlfile:path: ${user.home}/logs/seataextend:logstash-appender:destination: 127.0.0.1:4560kafka-appender:bootstrap-servers: 127.0.0.1:9092topic: logback_to_logstashconsole:user:username: seatapassword: seata

1. ?然后在nacos中加入seata配置，注意ID是上述配置文件中的?seataServer.properties，Group與第2步中的保持一致，這里是SEATA_GROUP

#Transaction storage configuration, only for the server.
store.mode=db
store.lock.mode=db
store.session.mode=db#These configurations are required if the `store mode` is `db`.
store.db.datasource=druid
store.db.dbType=mysql
store.db.driverClassName=com.mysql.cj.jdbc.Driver
store.db.url=jdbc:mysql://127.0.0.1:3306/seata?useSSL=false&useUnicode=true&rewriteBatchedStatements=true
store.db.user=root
store.db.password=admin
store.db.minConn=5
store.db.maxConn=30
store.db.globalTable=global_table
store.db.branchTable=branch_table
store.db.distributedLockTable=distributed_lock
store.db.queryLimit=100
store.db.lockTable=lock_table
store.db.maxWait=5000

• 然后就是創(chuàng)建上述配置文件的數(shù)據(jù)庫(kù)

代碼的相關(guān)編寫（所有的代碼會(huì)在后面貼出，這里只講關(guān)鍵代碼）

框架的搭建

????????關(guān)于微服務(wù)的搭建此處將不再贅述，可以參考本人的系列文章

? ? ? ? 同時(shí)需要集成mybatis-plus，就是上面創(chuàng)建的數(shù)據(jù)庫(kù)，可以參考本人的系列文章

Seata依賴的添加

? ? ? ? 在每個(gè)微服務(wù)都加入seata依賴

<!-- 注意一定要引入對(duì)版本，要引入spring-cloud版本seata，而不是springboot版本的seata-->

簡(jiǎn)單的業(yè)務(wù)邏輯編寫---XA分布式事務(wù)

每個(gè)YML文件需要配置事務(wù)組和事務(wù)的類型（此處為XA）

service.vgroup-mapping下一定要有一個(gè)對(duì)應(yīng)這個(gè)名字的映射，映射到default（seata默認(rèn)的集群名稱），seata_tx_group為我們自定義的事務(wù)組，名字隨便起

data-source-proxy-mode 為所用的事務(wù)模式，默認(rèn)AT

?nacos方面，我們僅配置注冊(cè)項(xiàng)，根據(jù)個(gè)人配置

#seata客戶端配置
seata:enabled: trueapplication-id: seata_txtx-service-group: seata_tx_groupservice:vgroup-mapping:seata_tx_group: defaultregistry:type: nacosnacos:application: seata-serverserver-addr: 127.0.0.1:8848namespace:group: SEATA_GROUPdata-source-proxy-mode: XA

XA模式實(shí)現(xiàn)

關(guān)于分布式事務(wù)，只需要全局事務(wù)標(biāo)簽：@GlobalTransactional，每個(gè)本地事務(wù)加上@Transactional和不加效果一樣，但是建議還是加上

關(guān)于完成的源碼見參考demo
