Spring Cloud Alibaba 搭建(SeaTa篇)

 Seata 是一款开源的分布式事务解决方案,致力于在微服务架构下提供高性能和简单易用的分布式事务服务。微服务中不可或缺的事务处理,缺少分布式事务管理就会存在数据不统一的情况。

一、下载Seata

二、运行Seata

  配置文件registry.conf中可以配置注册中心,因为我要整合服务,之前使用的是nacos,所以这边修改一下即可。

registry {
  # file 、nacos 、eureka、redis、zk、consul、etcd3、sofa
  type = "nacos"

  nacos {
    application = "seata-server"
    serverAddr = "127.0.0.1:8848"
    group = "SEATA_GROUP"
    namespace = ""
    cluster = "default"
    username = "nacos"
    password = "nacos"
  }
......
}

config {
  # file、nacos 、apollo、zk、consul、etcd3
  type = "nacos"

  nacos {
    serverAddr = "127.0.0.1:8848"
    namespace = ""
    group = "SEATA_GROUP"
    username = "nacos"
    password = "nacos"
  }
.......
}

  接着配置file.conf,个人是使用mysql,后期好整合项目,也可以直接file存储。

  sql文件地址:https://github.com/seata/seata/blob/1.2.0/script/server/db/mysql.sql

## transaction log store, only used in seata-server
store {
  ## store mode: file、db、redis
  mode = "db"

  ## database store property
  db {
    ## the implement of javax.sql.DataSource, such as DruidDataSource(druid)/BasicDataSource(dbcp)/HikariDataSource(hikari) etc.
    datasource = "druid"
    ## mysql/oracle/postgresql/h2/oceanbase etc.
    dbType = "mysql"
    driverClassName = "com.mysql.jdbc.Driver"
    url = "jdbc:mysql://xxx.xxx.xxx.xxx:3306/seata"
    user = "root"
    password = "123"
    minConn = 5
    maxConn = 30
    globalTable = "global_table"  ## global_table、branch_table、lock_table这几个表需要导入,否则会报错
    branchTable = "branch_table"
    lockTable = "lock_table"
    queryLimit = 100
    maxWait = 5000
  }
  ......
}

  bin文件夹中就2个文件,window直接运行seata-server.bat,linux下可以命令运行

sh seata-server.sh

  然后登陆http://127.0.0.1:8848/nacos/index.html中查看服务列表,就可以看到

三、总结

  seata服务搭建异常顺利,已没有奇怪的bug,可能麻烦的是后面的整合到项目里才会有其他问题产生。
