注意： 使用 seata-spring-boot-starter 不需要手動(dòng)配置數(shù)據(jù)源代理和不需要在每個(gè)微服務(wù)下面加file.conf和register.conf的文件

• 第一步： 創(chuàng)建seata 數(shù)據(jù)庫(kù) 和 在參與seata的所有業(yè)務(wù)數(shù)據(jù)庫(kù)中添加undo_log 事物回滾日志表

1. 創(chuàng)建seata 數(shù)據(jù)庫(kù)腳本

CREATE TABLE IF NOT EXISTS `global_table`
(
    `xid`                       VARCHAR(128) NOT NULL,
    `transaction_id`            BIGINT,
    `status`                    TINYINT      NOT NULL,
    `application_id`            VARCHAR(32),
    `transaction_service_group` VARCHAR(32),
    `transaction_name`          VARCHAR(128),
    `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;

-- the table to store BranchSession data
CREATE TABLE IF NOT EXISTS `branch_table`
(
    `branch_id`         BIGINT       NOT NULL,
    `xid`               VARCHAR(128) NOT NULL,
    `transaction_id`    BIGINT,
    `resource_group_id` VARCHAR(32),
    `resource_id`       VARCHAR(256),
    `branch_type`       VARCHAR(8),
    `status`            TINYINT,
    `client_id`         VARCHAR(64),
    `application_data`  VARCHAR(2000),
    `gmt_create`        DATETIME(6),
    `gmt_modified`      DATETIME(6),
    PRIMARY KEY (`branch_id`),
    KEY `idx_xid` (`xid`)
) ENGINE = InnoDB
  DEFAULT CHARSET = utf8;

-- the table to store lock data
CREATE TABLE IF NOT EXISTS `lock_table`
(
    `row_key`        VARCHAR(128) NOT NULL,
    `xid`            VARCHAR(96),
    `transaction_id` BIGINT,
    `branch_id`      BIGINT       NOT NULL,
    `resource_id`    VARCHAR(256),
    `table_name`     VARCHAR(32),
    `pk`             VARCHAR(36),
    `gmt_create`     DATETIME,
    `gmt_modified`   DATETIME,
    PRIMARY KEY (`row_key`),
    KEY `idx_branch_id` (`branch_id`)
) ENGINE = InnoDB
  DEFAULT CHARSET = utf8;

2. 創(chuàng)建 undo_log 腳本

CREATE TABLE `undo_log` (
  `id` bigint(20) NOT NULL AUTO_INCREMENT,
  `branch_id` bigint(20) NOT NULL,
  `xid` varchar(100) NOT NULL,
  `context` varchar(128) NOT NULL,
  `rollback_info` longblob NOT NULL,
  `log_status` int(11) NOT NULL,
  `log_created` datetime NOT NULL,
  `log_modified` datetime NOT NULL,
  `ext` varchar(100) DEFAULT NULL,
  PRIMARY KEY (`id`),
  UNIQUE KEY `ux_undo_log` (`xid`,`branch_id`)
) ENGINE=InnoDB AUTO_INCREMENT=4 DEFAULT CHARSET=utf8 COMMENT='事物回滾日志表';

• 第二步： 去官網(wǎng)下載 seata-server-1.2.0 和 nacos-server-1.2.1
• 第三步： 修改配置信息 目的地址：seata-server-1.2.0\seata\conf

1. 修改 file.conf 將store.mode 改為 db 然后修改 db 數(shù)據(jù)庫(kù)鏈接信息

## transaction log store, only used in seata-server
store {
  ## store mode: file拼缝、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 = "druid"
    ## mysql/oracle/postgresql/h2/oceanbase etc.
    dbType = "mysql"
    driverClassName = "com.mysql.cj.jdbc.Driver"
    url = "jdbc:mysql://127.0.0.1:3306/seata?useUnicode=true&characterEncoding=UTF-8"
    user = "root"
    password = "123456"
    minConn = 5
    maxConn = 30
    globalTable = "global_table"
    branchTable = "branch_table"
    lockTable = "lock_table"
    queryLimit = 100
    maxWait = 5000
  }
}

2. 修改 registry.conf 將 registry.type 改為 nacos 和 config.type 改為 nacos 配置自己的nacos-server地址

registry {
  # file 症歇、nacos 、eureka、redis挽牢、zk、consul俺附、etcd3矛纹、sofa
  type = "nacos"

  nacos {
    application = "seata-server"
    serverAddr = "localhost:8848"
    namespace = "public"
    cluster = "default"
    username = ""
    password = ""
  }
  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"
  }
  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 霜医、apollo齿拂、zk、consul肴敛、etcd3
  type = "nacos"

  nacos {
    serverAddr = "localhost:8848"
    namespace = "public"
    group = "SEATA_GROUP"
    username = ""
    password = ""
  }
  consul {
    serverAddr = "127.0.0.1:8500"
  }
  apollo {
    appId = "seata-server"
    apolloMeta = "http://192.168.1.204:8801"
    namespace = "application"
  }
  zk {
    serverAddr = "127.0.0.1:2181"
    sessionTimeout = 6000
    connectTimeout = 2000
    username = ""
    password = ""
  }
  etcd3 {
    serverAddr = "http://localhost:2379"
  }
  file {
    name = "file.conf"
  }
}

• 第四步： 使用nacos作為配置中心署海，我們將seata配置信息config.txt初始到nacos-server中

1. 修改config.txt中db數(shù)據(jù)，配置文件在源碼中的目錄地址：seata\script\config-center
   修改 store.mode=db医男、store.db.driverClassName砸狞、 store.db.url、store.db.user镀梭、store.db.password

transport.serialization=seata
transport.compressor=none
metrics.enabled=false
metrics.registryType=compact
metrics.exporterList=prometheus
metrics.exporterPrometheusPort=9898

2. 執(zhí)行初始化配置腳本 nacos-config.sh 在源碼中目錄地址：seata\script\config-center\nacos
   sh nacos-config.sh nacos-server地址

sh nacos-config.sh 127.0.0.1

• 第五步：?jiǎn)?dòng)seata-server 和 nacos-server
  如果啟動(dòng)過(guò)程中沒(méi)有報(bào)錯(cuò)刀森，則啟動(dòng)成功

• 第六步：查看 nacos 中是否注冊(cè)服務(wù)成功
  以后修改配置信息 咋可以直接在nacos 上修改

• 第七步：改造參與seata 所有微服務(wù)pom.xml
  添加seata依賴

        </dependency>

• 第八步：改造參與seata 所有微服務(wù)application.yml
  添加seata配置信息 配置文件位于源碼目錄：seata\script\client\spring
  配置信息 根據(jù)自己需求精簡(jiǎn)更改，我是全部拷貝過(guò)來(lái)的

#================ seata config =======================

seata:
  enabled: true
  application-id: ${spring.application.name}
  tx-service-group: my_test_tx_group

      serverAddr: 127.0.0.1:8848
      group: SEATA_GROUP
      userName: ""
      password: ""
  registry:
    # 使用 nacos 注冊(cè)類型报账，通過(guò)nacos 發(fā)現(xiàn) seata-server

      namespace: public
      cluster: default
      userName: ""
      password: ""

• 第九步：在參與seata 所有微服務(wù)Application中添加exclude = {DataSourceAutoConfiguration.class}

@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class})
public class Application {
 public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

• 第十步：增加分布式事物xid 傳遞攔截器

SeataHandlerInterceptor

     * @throws Exception 異常
     */
    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
        String currentXid = RootContext.getXID();
        String globalXid = request.getHeader(RootContext.KEY_XID);
        if (StringUtils.isBlank(currentXid) && StringUtils.isNotBlank(globalXid)) {
            RootContext.bind(globalXid);
        }
        return true;
    }

    /**

     */
    @Override
    public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) throws Exception {
        String globalXid = request.getHeader(RootContext.KEY_XID);
        if (StringUtils.isBlank(globalXid)) {
            return;
        }
        String unBindXid = RootContext.unbind();
        //在事務(wù)期間被更改過(guò)
        if (!globalXid.equalsIgnoreCase(unBindXid)) {
            RootContext.bind(unBindXid);
        }
    }

}

• 第十一步：因?yàn)槭褂玫膕eata-spring-boot-starter 所以不需要在每個(gè)微服務(wù)下面加file.conf和register.conf的文件和手動(dòng)配置數(shù)據(jù)源代理
• 第十二步：在業(yè)務(wù)的發(fā)起方添加@GlobalTransactional 全局事物笙什，其他微服務(wù)參與者不需要配置@GlobalTransactional

• 第十三步 啟動(dòng)每個(gè)業(yè)務(wù)微服務(wù)孽拷，然后開始調(diào)試回滾，觀察回滾是否成功半抱，重點(diǎn)觀察log.info("事務(wù)xid{}" + RootContext.getXID()); xid 值是否一致
