spring cloud 集成seata记录

spring cloud 集成seata记录

下载安装包

地址

解压

配置

解压后是没有config.txt文件的，需要新建三个文件

1. config.txt 放在seata根目录下

这个文件要修改下面几个地方

这里要对应配置文件的这里

注意：这里有个坑，部署到服务器上面会因为服务器的版本过高导致驱动不匹配

需要将store.db.driverClassName=com.mysql.cj.jdbc.Driver修改成这个，并且去这里找到你的数据库所对应的版本驱动

1、mysql>select version(); 查看mqsql版本，我的版本是8.0.19。

2.然后将下载好的驱动放到lib目录下的jdbc目录下，并且删掉其他的驱动

这里的要新建一个Seata数据库并新建表：sql如下

SET NAMES utf8mb4;
SET FOREIGN_KEY_CHECKS = 0;

启动seata

1.使用conf目录下的nacos-config.sh，将config.txt文件里面的内容推送到nacos上

sudo bash nacos-config.sh -h localhost -p 8848 -u nacos -w nacos

注：windows平台可以使用Git 运行nacos-config.sh脚本

nacos-config.sh命令的参数如下：

sh nacos-config.sh -h localhost -p 8848 -u username -w password

Parameter Description:

-h: host, the default value is localhost.

-p: port, the default value is 8848.

-g: Configure grouping, the default value is 'SEATA_GROUP'.

-t: Tenant information, corresponding to the namespace ID field of Nacos, the default value is ''.

-u: username, nacos 1.2.0+ on permission control, the default value is ''.

-w: password, nacos 1.2.0+ on permission control, the default value is ''.

执行成功后，打开nacos控制台

2.启动seata

执行 seata-server-1.4.2\bin 目录下的 seata-server.bat/seata-server.sh 启动seata服务nohup bash seata-server.sh > seata.log 2>&1 &

打开nacos控制台，此时seata已经成功注册到nacos注册中心

代码配置

在parent文件增加依赖

 <alibaba.cloud.version>2.2.5.RELEASEalibaba.cloud.version>

			
            <dependency>
                <groupId>com.alibaba.cloudgroupId>
                <artifactId>spring-cloud-starter-alibaba-seataartifactId>
                <version>${alibaba.cloud.version}version>
            dependency>

以及所有子服务增加

		<dependency>
            <groupId>com.alibaba.cloudgroupId>
            <artifactId>spring-cloud-starter-alibaba-seataartifactId>
        dependency>

根据不同的服务增加不同的yml配置

# seata config
seata:
  enabled: true
  application-id: user-service # 这个根据不同的服务进行修改
  tx-service-group: my_test_tx_group # 事务群组（可以每个应用单独取名，也可以使用相同名字，独立起名需要配置nacos）
  registry:
    type: nacos
    nacos:
      server-addr: 127.0.0.1:8848
      namespace:
      cluster: default
  config:
    type: nacos
    nacos:
      namespace:
      server-addr: 127.0.0.1:8848

nacos配置也需要改变

spring:
  cloud:
    nacos:
      discovery:
        server-addr: 127.0.0.1:8848
      namespace: dev #根据不同的服务环境进行配置
    config:
      namespace: dev
      server-addr: 127.0.0.1:8848

使用

场景：A服务调用B服务

则在A服务的方法上增加这个注解

@GlobalTransactional(timeoutMills = 10000, name = "spring-cloud-seata", rollbackFor = Exception.class)

则在B服务的方法上增加这个注解

    @Transactional(rollbackFor = Exception.class)

参考链接

在linux执行.sh脚本启动seata的时候报gc的错，原因是jdk版本太高

解决方法：1是降低版本，2是去掉cms配置，但是去掉cms配置后又报下面的错

这里需要在配置文件增加一个这个

--add-opens=java.base/java.lang=ALL-UNNAMED

完整的linux启动脚本如下
