这篇具有很好参考价值的文章主要介绍了Spring Boot 集成Seata。希望对大家有所帮助。如果存在错误或未考虑完全的地方，请大家不吝赐教，您也可以点击"举报违法"按钮提交疑问。

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：下载Seata

第二步：为了更好看到效果，我们将Seata的数据存储改为db

将seata\script\server\db\mysql.sql语句在mysql中执行，创建相关表

然后修改seata配置文件，相关配置可以参考application.example.yml，此处修改mode为db并且配置db相关配置

启动seata：

第三步：Spring Boot集成Seata

1.pom.xml导包：

<!--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

就两步完成Spring Boot集成Seata

测试：

1.首先在portal标明分布式事务
