SpringCloud教程 | 第八篇: 使用seata处理分布式事务

news2024/12/30 2:42:43

1、参考程序员江小北

2、打算降低nacos版本，先学通再看看升级到高版本nacos能不能正常使用。

3、nacos用1.4.1，正常启动单机版的了

4、seata用2.0.0

我看江小北说用的1.4.0的seata，但是图片中的目录文件都找不到，倒是在2.0.0的seata中找到了，于是使用2.0.0的seata

4.1导入seata数据库

4.2、在源码目录下打开GitBash,输入shnacos-config.sh，导入完成后，可在nacos中查看到所有配置；

5、修改seata配置文件，修改注册中心及配置中心为nacos,配置nacos地址；

参考江小北的，发现启动不了服务了。

搜了一圈资料，发现有个模板文件可以参考：

application.yml文件最终内容如下：
