Seata1.3.0集成Nacos

修改file.conf

修改mode为db,在修改连接信息

修改registry.conf

注意：application为seata启动后注册到nacos的服务名(愿意改就改,不愿意改就默认就行)
注:group默认为:SEATA_GROUP,更改DEFAULT_GROUP
或者和自己服务相同的group,否则会报错No available service

修改registry模块的type, 为自己注册中心的类型，以及注册中心的地址信息

注意：在registry.conf 配置文件中还有 config模块，type默认为file,他代表使用配置文件的类型，如果改为nacos的话，需要在nacos配置文件中生成。

修改从0.9.0版本拉过来的nacos-conf.txt文件

注意：1.0版本以后，service.vgroupMapping使用的是驼峰

如果使用的config模块使用的是nacos，则需要修改nacos-config.sh脚本中的group 跟registry模板中的一致

修改完毕后执行1.3.0/conf下的nacos-config.sh命令为:sh nacos-config.sh 127.0.0.1
127.0.0.1为nacos地址,按实际情况修改即可
windows系统可以使用git-bash执行,命令同上

启动nacos以及seata1.3.0

启动成功

集成SpringBoot

1. 修改pom

<!--seata依赖-->
		<dependency>
			<groupId>com.alibaba.cloud</groupId>
			<artifactId>spring-cloud-starter-alibaba-seata</artifactId>
			<exclusions>
				<exclusion>
					<groupId>io.seata</groupId>
					<artifactId>seata-all</artifactId>
				</exclusion>
			</exclusions>
		</dependency>

		<!--使用和自己下载的版本一致-->
		<dependency>
			<groupId>io.seata</groupId>
			<artifactId>seata-all</artifactId>
			<version>1.3.0</version>
		</dependency>

2. 将registry.conf 和 file.conf 配置文件复制到 项目的 resources 目录下
   
   注意：file.conf 需要使用0.9版本的file.conf,否则会报 no available service 'null' found, please make sure registry config correct,具体文件如下

file.conf

transport {
  # tcp udt unix-domain-socket
  type = "TCP"
  #NIO NATIVE
  server = "NIO"
  #enable heartbeat
  heartbeat = true
  #thread factory for netty
  thread-factory {
    boss-thread-prefix = "NettyBoss"
    worker-thread-prefix = "NettyServerNIOWorker"
    server-executor-thread-prefix = "NettyServerBizHandler"
    share-boss-worker = false
    client-selector-thread-prefix = "NettyClientSelector"
    client-selector-thread-size = 1
    client-worker-thread-prefix = "NettyClientWorkerThread"
    # netty boss thread size,will not be used for UDT
    boss-thread-size = 1
    #auto default pin or 8
    worker-thread-size = 8
  }
  shutdown {
    # when destroy server, wait seconds
    wait = 3
  }
  serialization = "seata"
  compressor = "none"
}
service {
  #vgroup->rgroup
  vgroupMapping.zh_tx_group = "default"
  #only support single node
  default.grouplist = "127.0.0.1:8091"
  #degrade current not support
  enableDegrade = false
  #disable
  disable = false
  #unit ms,s,m,h,d represents milliseconds, seconds, minutes, hours, days, default permanent
  max.commit.retry.timeout = "-1"
  max.rollback.retry.timeout = "-1"
}

client {
  async.commit.buffer.limit = 10000
  lock {
    retry.internal = 10
    retry.times = 30
  }
  report.retry.count = 5
  tm.commit.retry.count = 1
  tm.rollback.retry.count = 1
}

## transaction log store
store {
  ## store mode: file、db
  mode = "db"

  ## file store
  file {
    dir = "sessionStore"

    # branch session size , if exceeded first try compress lockkey, still exceeded throws exceptions
    max-branch-session-size = 16384
    # globe session size , if exceeded throws exceptions
    max-global-session-size = 512
    # file buffer size , if exceeded allocate new buffer
    file-write-buffer-cache-size = 16384
    # when recover batch read size
    session.reload.read_size = 100
    # async, sync
    flush-disk-mode = async
  }

  ## database store
  db {
    ## the implement of javax.sql.DataSource, such as DruidDataSource(druid)/BasicDataSource(dbcp) etc.
    datasource = "dbcp"
    ## mysql/oracle/h2/oceanbase etc.
    db-type = "mysql"
    driver-class-name = "com.mysql.jdbc.Driver"
    url = "jdbc:mysql://localhost:33306/seata?characterEncoding=UTF-8&useUnicode=true&useSSL=false&tinyInt1isBit=false&allowMutiQueries=true"
    user = "root"
    password = "123456"
    min-conn = 1
    max-conn = 3
    global.table = "global_table"
    branch.table = "branch_table"
    lock-table = "lock_table"
    query-limit = 100
  }
}
lock {
  ## the lock store mode: local、remote
  mode = "remote"

  local {
    ## store locks in user's database
  }

  remote {
    ## store locks in the seata's server
  }
}
recovery {
  #schedule committing retry period in milliseconds
  committing-retry-period = 1000
  #schedule asyn committing retry period in milliseconds
  asyn-committing-retry-period = 1000
  #schedule rollbacking retry period in milliseconds
  rollbacking-retry-period = 1000
  #schedule timeout retry period in milliseconds
  timeout-retry-period = 1000
}

transaction {
  undo.data.validation = true
  undo.log.serialization = "jackson"
  undo.log.save.days = 7
  #schedule delete expired undo_log in milliseconds
  undo.log.delete.period = 86400000
  undo.log.table = "undo_log"
}

## metrics settings
metrics {
  enabled = false
  registry-type = "compact"
  # multi exporters use comma divided
  exporter-list = "prometheus"
  exporter-prometheus-port = 9898
}

support {
  ## spring
  spring {
    # auto proxy the DataSource bean
    datasource.autoproxy = false
  }
}

3. 修改yml 配置文件

spring:
  application:
    name: seata-account-service
  cloud:
    nacos:
      discovery:
        server-addr: localhost:8848 # nacos注册中心地址
    alibaba:
      seata:
        # 自定义事务组名称需要与seata-server中file.conf 配置文件中配置的一致
        tx-service-group: zh_tx_group

然后启动测试即可
