1.4.2啟動(dòng)
通過(guò)環(huán)境變量SEATA_CONFIG_NAME指定配置文件位置/root/seata-config/registry.confdocker run --name seata-server \ -p 8091:8091 \ -e SEATA_CONFIG_NAME=file:/root/seata-config/registry \ -v /User/seata/config:/root/seata-config \ seataio/seata-server配置文件
實(shí)現(xiàn)高可用需要依賴(lài)注冊(cè)中心，配置中心，數(shù)據(jù)庫(kù)
registry { type = "nacos" nacos { application = "seata-server" serverAddr = "192.168.199.2" namespace = "test" group = "SEATA_GROUP" cluster = "default" username = "" password = "" }}config { type = "nacos" nacos { serverAddr = "192.168.199.2" namespace = "test" group = "SEATA_GROUP" username = "" password = "" }}NACOS配置
注：使用nacos配置，需要在對(duì)應(yīng)分組(SEATA_GROUP)下針對(duì)配置項(xiàng)目逐條配置文本值，而不是創(chuàng)建包含所有配置的properties文件，可以使用官方源碼中的
全部可用配置
1. 使用數(shù)據(jù)庫(kù)
store.mode=db
store.db.datasource=druid
store.db.dbType=mysql
store.db.driverClassName=com.mysql.jdbc.Driver
store.db.url=jdbc:mysql://192.168.199.2:3306/seata?useUnicode=true&rewriteBatchedStatements=true
store.db.user=root
創(chuàng)建數(shù)據(jù)庫(kù)-- -------------------------------- The script used when storeMode is 'db' ---------------------------------- the table to store GlobalSession dataCREATE 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 dataCREATE 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 dataCREATE TABLE IF NOT EXISTS `lock_table`( `row_key` VARCHAR(128) NOT NULL, `xid` VARCHAR(128), `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;異常處理
1. 客戶端報(bào)錯(cuò) Data too long for column ‘a(chǎn)pplication_id'
io.seata.core.exception.TmTransactionException: TransactionException[begin global request failed. xid=null, msg=Data truncation: Data too long for column ‘a(chǎn)pplication_id' at row 1]
at io.seata.tm.DefaultTransactionManager.begin(DefaultTransactionManager.java:55) ~[seata-all-1.3.0.jar:1.3.0]
at io.seata.tm.api.DefaultGlobalTransaction.begin(DefaultGlobalTransaction.java:104) ~[seata-all-1.3.0.jar:1.3.0]
at io.seata.tm.api.TransactionalTemplate.beginTransaction(TransactionalTemplate.java:175) ~[seata-all-1.3.0.jar:1.3.0]
seata數(shù)據(jù)庫(kù)global_table.application_id字段默認(rèn)長(zhǎng)度為varchar(32)，如果客戶端應(yīng)用ID超長(zhǎng)則報(bào)此錯(cuò)
手動(dòng)修改字段類(lèi)型增加長(zhǎng)度即可
