在此之前我搞了一天，雖然seata好用，用起來也超級簡單，但是安裝配置是真的麻煩，遇見了各種坑，下面來進入正題。o(╥﹏╥)o
一 . 版本
注意：如果版本不匹配也會有各種報錯，可以根據官網匹配版本。
seata：1.3.0
alibaba.cloud：2.2.3.RELEASE
nacos：2.0.2
二. docker安裝搭建seata服務端
2.1 下載seata鏡像
docker pull seataio/seata-server:1.3.0
2.2 在Linux目錄下創建registry.conf，我的路徑在/data/seate/registry.conf，接下來的所有創建都在這個目錄下
cd /data
mkdir seate
vim registry.conf
2.3 registry.conf中的內容如下
registry {
type = "nacos"
nacos {
application = "seata-server"
serverAddr = "127.0.0.1:8848"
group = "SEATA_GROUP"
namespace = ""
cluster = "default"
username = ""
password = ""
}
}
config {
type = "nacos"
nacos {
serverAddr = "127.0.0.1:8848"
namespace = ""
group = "SEATA_GROUP"
username = ""
password = ""
}
}
注意registry和config需要在同一個組下,注冊中心我用的是nacos，注意nacos的地址要改。
----->>>這里我插一句，需要新建一個數據庫seata，并且新建三張表，
-- -------------------------------- 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_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;
實現分布式每個業務庫都要加一張表undo_log，不然會報錯，
CREATE TABLE `undo_log` (
`id` bigint(20) NOT NULL AUTO_INCREMENT COMMENT '主鍵',
`branch_id` bigint(20) NOT NULL COMMENT 'branch transaction id',
`xid` varchar(100) 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',
PRIMARY KEY (`id`),
UNIQUE KEY `ux_undo_log` (`xid`,`branch_id`)
) ENGINE=InnoDB AUTO_INCREMENT=9 DEFAULT CHARSET=utf8 COMMENT='AT transaction mode undo table';
2.4 創建推送配置文件 vim config.txt，是將文件中的配置推送到nacos中去。
service.vgroupMapping.btb_tx_group=default
store.mode=db
store.db.datasource=druid
store.db.dbType=mysql
store.db.driverClassName=com.mysql.cj.jdbc.Driver
store.db.url=jdbc:mysql://172.0.0.1:3306/seata?useUnicode=true
store.db.user=root
store.db.password=root
store.db.minConn=5
store.db.maxConn=30
store.db.globalTable=global_table
store.db.branchTable=branch_table
store.db.queryLimit=100
store.db.lockTable=lock_table
store.db.maxWait=5000
注意btb_tx_group需要與客戶端保持一致,順便注意數據庫驅動，如果是8以上用我的這個驅動，5.7的用com.mysql.jdbc.Driver
2.5 創建推送腳本，因為執行腳本要在config.txt的下一層，所有加一層目錄
mkdir sh
cd sh
vim nacos-config.sh
內容如下：最好不要有任何的修改

while getopts ":h:p:g:t:u:w:" opt

case $opt in

echo " USAGE OPTION: $0 [-h host] [-p port] [-g group] [-t tenant] [-u username] [-w password] "
exit 1
;;
esac
done
if [[ -z ${host} ]]; then
host=localhost
fi
if [[ -z ${port} ]]; then
port=8848

nacosAddr=$host:$port

echo "set nacosAddr=$nacosAddr"
echo "set group=$group"
failCount=0
tempLog=$(mktemp -u)
function addConfig() {
curl -X POST -H "${contentType}" "http://$nacosAddr/nacos/v1/cs/configs?dataId=$1&group=$group&content=$2&tenant=$tenant&username=$username&password=$password" >"${tempLog}" 2>/dev/null
if [[ -z $(cat "${tempLog}") ]]; then
echo " Please check the cluster status. "
exit 1
fi
if [[ $(cat "${tempLog}") =~ "true" ]]; then
echo "Set $1=$2 successfully "
else
echo "Set $1=$2 failure "
(( failCount++ ))
fi
}
count=0
for line in $(cat $(dirname "$PWD")/config.txt | sed s/[[:space:]]//g); do
(( count++ ))
key=${line%%=*}
value=${line#*=}
addConfig "${key}" "${value}"
done
echo "========================================================================="
echo " Complete initialization parameters, total-count:$count , failure-count:$failCount "
echo "========================================================================="
if [[ ${failCount} -eq 0 ]]; then
echo " Init nacos config finished, please start seata-server. "
else
echo " init nacos config fail. "
fi
2.6 執行推送腳本，后面是nacos的ip地址，如果端口不是8848還需要加一個-p 8884你的端口
bash nacos-config.sh -h 127.0.0.1
2.7 創建容器，注意SEATA_IP如果是阿里云服務器需要寫外網ip
docker run -d --restart always --name seata-server -p 8091:8091 -e SEATA_IP=172.0.0.1 -e SEATA_CONFIG_NAME=file:/data/seata/registry -v /data/seata:/data/seata seataio/seata-server:1.3.0
三 . 客戶端（也就是微服務，項目中使用seata）
3.1 pom.xml 引入依賴
<!-- seata分布式事務-->
<dependency>
<groupId>com.alibaba.cloud</groupId>
<artifactId>spring-cloud-starter-alibaba-seata</artifactId>
<exclusions>
<exclusion>
<groupId>io.seata</groupId>
<artifactId>seata-spring-boot-starter</artifactId>
</exclusion>
</exclusions>
</dependency>
<dependency>
<groupId>io.seata</groupId>
<artifactId>seata-spring-boot-starter</artifactId>
<version>1.3.0</version>
</dependency>
注意這里一定要剔除原來自帶的 io.seata包，并且服務端和客戶端的包版本要一致。
3.2 配置項目配置文件
#seata
seata.application-id=${spring.application.name}
seata.tx-service-group=btb_tx_group
seata.config.type=nacos
seata.config.nacos.server-addr=172.0.0.1:8848
seata.config.nacos.group=SEATA_GROUP
seata.registry.type=nacos
seata.registry.nacos.application=seata-server
seata.registry.nacos.server-addr=172.0.0.1:8848
seata.registry.nacos.group=SEATA_GROUP
注意：這里的btb_tx_group要跟服務端的vgroupMapping后面的key保持一致，
如：service.vgroupMapping.btb_tx_group=default
3.3 加入注解使用
擴展： 我用的是一個數據庫，執行報錯，說我缺少主鍵，于是我在表undo_log加了一個增的主鍵id，上面的創建undo_log表的sql是我加了id的，官方給的是沒有id的。請知曉！！！！
問題：單數源是有報錯的，原因是因為我是一個數據庫，需要設置代理配置如下 ，根據自己實際情況是指配置文件，不然會報錯
#單數據源
seata.enable-auto-data-source-proxy=true
#多數據源
seata.enable-auto-data-source-proxy=false
