Seata的集成方式有：

1. Seata-All

2. Seata-Spring-Boot-Starter

3. Spring-Cloud-Starter-Seata

本案例使用Seata-Spring-Boot-Starter演示：

第一步：下載Seata

第二步：為了更好看到效果，我們將Seata的數(shù)據(jù)存儲改為db

將seata\script\server\db\mysql.sql語句在mysql中執(zhí)行，創(chuàng)建相關表

?

然后修改seata配置文件，相關配置可以參考application.example.yml，此處修改mode為db并且配置db相關配置

?

啟動seata：

?

第三步：Spring Boot集成Seata

1.pom.xml導包：

<!--seata-->
<dependency>
    <groupId>io.seata</groupId>
    <artifactId>seata-spring-boot-starter</artifactId>
    <version>1.4.2</version>
</dependency>
<dependency>
    <groupId>com.esotericsoftware</groupId>
    <artifactId>kryo</artifactId>
</dependency>
<dependency>
    <groupId>de.javakaffee</groupId>
    <artifactId>kryo-serializers</artifactId>
</dependency>
        

2.application.properties添加seata配置

#env

dubbo.application.name=coupon-service
dubbo.protocol.port=-1

#========== seata config =============
seata.data-source-proxy-mode=AT
#tx group

#tx group cluster

seata.client.undo.log-serialization=kryo

就兩步完成Spring Boot集成Seata

測試：

1.首先在portal標明分布式事務

2.postman調用?

?打斷點調試

?異常觸發(fā)前，看到數(shù)據(jù)插入成功，且undo_log有兩條數(shù)據(jù)

斷點繼續(xù)往下走，觸發(fā)異常，，已插入的數(shù)據(jù)被回滾，且undo_log被清空，分布式事務回滾正常。

?
