Windows下部署Seata1.5.2，解决Seata无法启动问题
3. 解决Seata无法启动问题
1. 版本说明
（1） spring-cloud-alibaba:2021.0.4.0 对应 seata-all:1.5.2，所以选择 Seata1.5.2 版本；
（2）目前 Seata 支持的 JDK版本为 JDK8、JDK11，这里使用JDK8。
2. Windows下部署Seata1.5.2
2.1 创建回滚日志表undo_log
注意：需要用到分布式事务的数据库都要创建这个表。
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',
`context` VARCHAR(128) NOT NULL COMMENT 'undo_log context,such as serialization',
`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 = utf8mb4 COMMENT ='AT transaction mode undo table';
ALTER TABLE `undo_log` ADD INDEX `ix_log_created` (`log_created`);
2.2 创建Seata服务端需要的四张表
注意：Seata存储模式store.mode=db，在Seata服务端需要连接的数据路seata里创建一下四张表。
-- -------------------------------- The script used when storeMode is 'db' --------------------------------
-- the table to store GlobalSession data
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_status_gmt_modified` (`status` , `gmt_modified`),
KEY `idx_transaction_id` (`transaction_id`)
) ENGINE = InnoDB
DEFAULT CHARSET = utf8mb4;
-- 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 = utf8mb4;
-- the table to store lock data
CREATE 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),
`status` TINYINT NOT NULL DEFAULT '0' COMMENT '0:locked ,1:rollbacking',
`gmt_create` DATETIME,
`gmt_modified` DATETIME,
PRIMARY KEY (`row_key`),
KEY `idx_status` (`status`),
KEY `idx_branch_id` (`branch_id`),
KEY `idx_xid_and_branch_id` (`xid` , `branch_id`)
) ENGINE = InnoDB
DEFAULT CHARSET = utf8mb4;
CREATE TABLE IF NOT EXISTS `distributed_lock`
(
`lock_key` CHAR(20) NOT NULL,
`lock_value` VARCHAR(20) NOT NULL,
`expire` BIGINT,
primary key (`lock_key`)
) ENGINE = InnoDB
DEFAULT CHARSET = utf8mb4;
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);2.3 在nacos创建seata命名空间，添加seataServer.yml配置
seataServer.yml如下：
内容如下：

2.5 启动Seata
seata-server.bat -h 127.0.0.1 -m db
2.6 测试
浏览器输入网址：http://localhost:7091/，输入用户名和密码登录Seata。
注意：登录Seata的用户名密码默认是seata seata，可自定配置，修改application.yml的配置，如下：
3. 解决Seata无法启动问题
当在Windows下，进入Seata的bin目录下，输入cmd回车，输入Seata启动命令，如下：
seata-server.bat -h 127.0.0.1 -m db
（1）报错信息，如下：
（2）错误原因：
（1）在启动Seata Server时，Java虚拟机不认识CMSParallelRemarkEnabled 这个选项。
（2）CMSParallelRemarkEnabled 是与 CMS（Concurrent Mark-Sweep）垃圾回收器相关的选项，但在较新的 Java 版本中被移除了。
注意：目前Seata支持JDK8或JDK11。
（3）解决方案：
打开seata/bin目录下的seata-server.bat文件，将以下配置：
if "%JAVACMD%"=="" set JAVACMD=java
修改为，如下：
// 本地jdk路径
if "%JAVACMD%"=="" set JAVACMD="D:\Java\jdk1.8.0_251\bin\java.exe"
