标签：file seata1.4 seata lock 配置 nacos client 版本 store


1.修改seata里面配置

1.1conf配置修改

在这里插入图片描述

## transaction log store, only used in seata-server
store {
  ## store mode: file、db、redis
  mode = "db"
  ## rsa decryption public key
  publicKey = ""
  ## 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   修改成你的数据库信息
  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.cj.jdbc.Driver"
    ## if using mysql to store the data, recommend add rewriteBatchedStatements=true in jdbc connection param
    url = "jdbc:mysql://ip:3306/seata?rewriteBatchedStatements=true"
    user = "root"
    password = "2317816768"
    minConn = 5
    maxConn = 100
    globalTable = "global_table"
    branchTable = "branch_table"
    lockTable = "lock_table"
    queryLimit = 100
    maxWait = 5000
  }

  ## redis store property
  redis {
    ## redis mode: single、sentinel
    mode = "single"
    ## single mode property
    single {
      host = "127.0.0.1"
      port = "6379"
    }
    ## sentinel mode property
    sentinel {
      masterName = ""
      ## such as "10.28.235.65:26379,10.28.235.65:26380,10.28.235.65:26381"
      sentinelHosts = ""
    }
    password = ""
    database = "0"
    minConn = 1
    maxConn = 10
    maxTotal = 100
    queryLimit = 100
  }
}

1.2.registry配置修改

在这里插入图片描述

registry {
  # file 、nacos 、eureka、redis、zk、consul、etcd3、sofa
  type = "nacos"
#修改成你的nacos  ip
  nacos {
    application = "seata-server"
    serverAddr = "127.0.0.1:8848"
    group = "SEATA_GROUP"
    namespace = "public"
    cluster = "default"

    password = "nacos"
  }
  eureka {
    serviceUrl = "http://localhost:8761/eureka"
    application = "default"
    weight = "1"
  }
  redis {
    serverAddr = "localhost:6379"
    db = 0
    password = ""
    cluster = "default"
    timeout = 0
  }
  zk {
    cluster = "default"
    serverAddr = "127.0.0.1:2181"
    sessionTimeout = 6000
    connectTimeout = 2000
    username = ""
    password = ""
  }
  consul {
    cluster = "default"
    serverAddr = "127.0.0.1:8500"
    aclToken = ""
  }
  etcd3 {
    cluster = "default"
    serverAddr = "http://localhost:2379"
  }
  sofa {
    serverAddr = "127.0.0.1:9603"

    group = "SEATA_GROUP"
    addressWaitTime = "3000"
  }
  file {
    name = "file.conf"
  }
}
#修改成你的nacos  ip
config {
  # file、nacos 、apollo、zk、consul、etcd3
  type = "nacos"

  nacos {
    serverAddr = "127.0.0.1:8848"
    namespace = "public"
    group = "SEATA_GROUP"

    dataId = "seataServer.properties"
  }
  consul {
    serverAddr = "127.0.0.1:8500"
    aclToken = ""
  }
  apollo {
    appId = "seata-server"
    ## apolloConfigService will cover apolloMeta
    apolloMeta = "http://192.168.1.204:8801"
    apolloConfigService = "http://192.168.1.204:8080"
    namespace = "application"
    apolloAccesskeySecret = ""
    cluster = "seata"
  }
  zk {
    serverAddr = "127.0.0.1:2181"
    sessionTimeout = 6000
    connectTimeout = 2000
    username = ""
    password = ""
    nodePath = "/seata/seata.properties"
  }
  etcd3 {
    serverAddr = "http://localhost:2379"
  }
  file {
    name = "file.conf"
  }
}

2.配置数据库

    `timeout`                   INT,
    `begin_time`                BIGINT,
    `application_data`          VARCHAR(2000),
    `gmt_create`                DATETIME,
    `gmt_modified`              DATETIME,
    PRIMARY KEY (`xid`),
    KEY `idx_gmt_modified_status` (`gmt_modified`, `status`),
    KEY `idx_transaction_id` (`transaction_id`)
    ) ENGINE = INNODB
    DEFAULT CHARSET = utf8;
 
-- 分支表

    KEY `idx_xid` (`xid`)
    ) ENGINE = INNODB
    DEFAULT CHARSET = utf8;
 
-- 锁定表
CREATE TABLE IF NOT EXISTS `lock_table`

    ) ENGINE = INNODB
    DEFAULT CHARSET = utf8;
 
CREATE TABLE IF NOT EXISTS `distributed_lock`

INSERT INTO `distributed_lock` (lock_key, lock_value, expire) VALUES ('AsyncCommitting', ' ', 0);
INSERT INTO `distributed_lock` (lock_key, lock_value, expire) VALUES ('RetryCommitting', ' ', 0);
INSERT INTO `distributed_lock` (lock_key, lock_value, expire) VALUES ('RetryRollbacking', ' ', 0);
INSERT INTO `distributed_lock` (lock_key, lock_value, expire) VALUES ('TxTimeoutCheck', ' ', 0);

回滚日志表 在每个需要开启seata事务操作的数据库下都需要建立此表。

--日志文件表--
CREATE TABLE IF NOT EXISTS `undo_log`
(
    `branch_id`     BIGINT       NOT NULL COMMENT 'branch transaction id',
    `xid`           VARCHAR(128) NOT NULL COMMENT 'global transaction id',

    `rollback_info` LONGBLOB     NOT NULL COMMENT 'rollback info',
    `log_status`    INT(11)      NOT NULL COMMENT '0:normal status,1:defense status',
    `log_created`   DATETIME(6)  NOT NULL COMMENT 'create datetime',
    `log_modified`  DATETIME(6)  NOT NULL COMMENT 'modify datetime',
    UNIQUE KEY `ux_undo_log` (`xid`, `branch_id`)
    ) ENGINE = INNODB
    AUTO_INCREMENT = 1
    DEFAULT CHARSET = utf8 COMMENT ='AT transaction mode undo table';

3.创建springboot项目

启动类加上
@EnableAutoDataSourceProxy
@EnableDiscoveryClient
@SpringBootApplication

3.1 bootstrap.yml 配置

seata:
  enabled: true
  enable-auto-data-source-proxy: true #是否开启数据源自动代理,默认为true
  tx-service-group: default  #要与配置文件中的vgroupMapping一致
  registry:  #registry根据seata服务端的registry配置
    type: nacos #默认为file
    nacos:
      application: seata-server #配置自己的seata服务
      server-addr: 127.0.0.1:8848 #根据自己的seata服务配置
      username: nacos #根据自己的seata服务配置
      password: nacos #根据自己的seata服务配置
      namespace: public #根据自己的seata服务配置
      cluster: default # 配置自己的seata服务cluster, 默认为 default
      group: SEATA_GROUP #根据自己的seata服务配置
  config:
    type: nacos #默认file,如果使用file不配置下面的nacos,直接配置seata.service
    nacos:
      server-addr: 127.0.0.1:8848 #配置自己的nacos地址
      group: SEATA_GROUP #配置自己的dev
      username: nacos #配置自己的username
      password: nacos #配置自己的password
      namespace: public #配置自己的namespace
      dataId: seataServer.properties #配置自己的dataId,由于搭建服务端时把客户端的配置也写在了seataServer.properties,所以这里用了和服务端一样的配置文件,实际客户端和服务端的配置文件分离出来更好

3.2 application.yml配置

server:
  port: 55
spring:
  datasource:
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://ip:3306/order?useUnicode=true&characterEncoding=utf-8&serverTimezone=UTC
    username: root
    password: 2317816768
  main:
    allow-circular-references: true
  application:
    name: XXX
  cloud:
    nacos:
      discovery:
        server-addr: 127.0.0.1:8848
