【全栈之路】seata1.1.0分布式事务Springboot尝鲜体验

项目开源地址：https://gitee.com/shuogesha/shop2020

本次采用seata的docker安装的方式，准备docker环境，如果需要持久化mysql，或者配置nacos请同步需要的配置，本次就不再细说啦！好了我们开始：

docker pull seataio/seata-server

 完成后docker images看下是否成功

尝试执行启动

docker run --name seata-server -p 8091:8091  -d seataio/seata-server:latest

然后docker ps -a 看是否运行，如果没启动成功自己看下那里错了

默认的配置请打docker exec -it  容器id bash里面去看下

root@8f911515cc45:/seata-server# cd resources/
root@8f911515cc45:/seata-server/resources# ls
META-INF  README-zh.md    README.md  file.conf  file.conf.example  io  logback.xml  registry.conf
root@8f911515cc45:/seata-server/resources# pwd
/seata-server/resources
root@8f911515cc45:/seata-server/resources#

当然可以自定义配置具体看dockerhub的文章和教程

容器命令行及查看日志

$ docker exec -it seata-server sh

$ tail -f /root/logs/seata/seata-server.log

使用自定义配置文件

The default configuration could be found under path /seata-server/resources, suggest that put your custom configuration under other directories. And the environment variableSEATA_CONFIG_NAME is required when use custom configuration, and the value must be started with file: like file:/root/seata-config/registry:

默认的配置文件路径为 /seata-server/resources，建议将自定义配置文件放到其他目录下; 使用自定义配置文件时必须指定环境变量 SEATA_CONFIG_NAME，并且环境变量的值需要以file:开始, 如: seata-config/registry

$ docker run --name seata-server \
        -p 8091:8091 \
        -e SEATA_CONFIG_NAME=file:/root/seata-config/registry \
        -v /PATH/TO/CONFIG_FILE:/root/seata-config  \
        seataio/seata-server

具体的配置可以从容器里面copy出去，registry.conf

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

  nacos {
    serverAddr = "localhost"
    namespace = ""
    cluster = "default"
  }
  eureka {
    serviceUrl = "http://localhost:8761/eureka"
    application = "default"
    weight = "1"
  }
  redis {
    serverAddr = "localhost:6379"
    db = "0"
  }
  zk {
    cluster = "default"
    serverAddr = "127.0.0.1:2181"
    session.timeout = 6000
    connect.timeout = 2000
  }
  consul {
    cluster = "default"
    serverAddr = "127.0.0.1:8500"
  }
  etcd3 {
    cluster = "default"
    serverAddr = "http://localhost:2379"
  }
  sofa {
    serverAddr = "127.0.0.1:9603"
    application = "default"
    region = "DEFAULT_ZONE"
    datacenter = "DefaultDataCenter"
    cluster = "default"
    group = "SEATA_GROUP"
    addressWaitTime = "3000"
  }
  file {
    name = "file.conf"
  }
}

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

  nacos {
    serverAddr = "localhost"
    namespace = ""
    group = "SEATA_GROUP"
  }
  consul {
    serverAddr = "127.0.0.1:8500"
  }
  apollo {
    app.id = "seata-server"
    apollo.meta = "http://192.168.1.204:8801"
    namespace = "application"
  }
  zk {
    serverAddr = "127.0.0.1:2181"
    session.timeout = 6000
    connect.timeout = 2000
  }
  etcd3 {
    serverAddr = "http://localhost:2379"
  }
  file {
    name = "file.conf"
  }
}

file.conf

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

  ## file store property
  file {
    ## store location dir
    dir = "sessionStore"
    # branch session size , if exceeded first try compress lockkey, still exceeded throws exceptions
    maxBranchSessionSize = 16384
    # globe session size , if exceeded throws exceptions
    maxGlobalSessionSize = 512
    # file buffer size , if exceeded allocate new buffer
    fileWriteBufferCacheSize = 16384
    # when recover batch read size
    sessionReloadReadSize = 100
    # async, sync
    flushDiskMode = async
  }

  ## database store property
  db {
    ## the implement of javax.sql.DataSource, such as DruidDataSource(druid)/BasicDataSource(dbcp) etc.
    datasource = "dbcp"
    ## mysql/oracle/h2/oceanbase etc.
    dbType = "mysql"
    driverClassName = "com.mysql.jdbc.Driver"
    url = "jdbc:mysql://mysql5.6:3306/base2020"
    user = "root"
    password = "yi"
    minConn = 1
    maxConn = 10
    globalTable = "global_table"
    branchTable = "branch_table"
    lockTable = "lock_table"
    queryLimit = 100
  }
}

我这里的单体boot就直接存mysql了，mysql的docker跑起来后，执行命令

docker run --name seata-server -p 8091:8091 --link mysql5.6:mysql5.6 -e SEATA_CONFIG_NAME=file:/root/seata-config/registry -v /Users/zhaohaiyuan/Downloads/docker/seata/config:/root/seata-config -v /Users/zhaohaiyuan/Downloads/docker/seata/log:/root/logs -d seataio/seata-server

 以上是准备工作，进行正题

配置pom.xml,加入依赖

 
        
            io.seata
            seata-spring-boot-starter
            1.1.0
        

配置yml

#====================================Seata Config===============================================

    type: TCP
    server: NIO
    heartbeat: true
    serialization: seata
    compressor: none
    enable-client-batch-send-request: true

然后进入业务异常提示

方法上加入@GlobalTransactional(timeoutMills = 300000, name = "base2020-seata-example")

@GlobalTransactional(timeoutMills = 300000, name = "base2020-seata-example")
    public void save(Notice bean) {
         dao.saveEntity(bean);
         throw new RuntimeException("notice branch exception");//看是否成功
    }

ok 提交数据测试

看日志
