SpringCloud整合Seata1.4.2

一、Nacos中新建一个命名空间 我这里是seata

 二、修改Seata文件

registry.conf 

 二、Seata的一些配置 写在config.txt里面

注意 config.txt要与conf在同一目录下

这里我就简单挑一些简单的配置，配置详细内容可以自行查看

seata/config.txt at develop · seata/seata · GitHub

#1.我这里配置了我的db的连接信息
store.db.datasource=druid
store.db.dbType=mysql
store.db.driverClassName=com.mysql.jdbc.Driver
store.db.url=jdbc:mysql://192.168.207.17:3306/seata?useUnicode=true&rewriteBatchedStatements=true
store.db.user=root
store.db.password=root
#2.修改分布式事务的分组
service.vgroupMapping.my_test_tx_group=default
#自己添加一个分组
service.vgroupMapping.gulimall-seata-service-group=default 

三、在conf目录下 新建一个nacos-config.sh脚本文件

}failCount=0
tempLog=$(mktemp -u)

"exit 1fiif [ "$(cat "${tempLog}")" == "true" ]; thenecho "Set $1=$2 successfully "elseecho "Set $1=$2 failure "failCount=`expr $failCount + 1`fi
}count=0
COMMENT_START="#"
for line in $(cat $(dirname "$PWD")/config.txt | sed s/[[:space:]]//g); doif [[ "$line" =~ ^"${COMMENT_START}".*  ]]; thencontinueficount=`expr $count + 1`key=${line%%=*}value=${line#*=}addConfig "${key}" "${value}"
doneecho "========================================================================="
echo " Complete initialization parameters,  total-count:$count ,  failure-count:$failCount "
echo "========================================================================="if [ ${failCount} -eq 0 ]; thenecho " Init nacos config finished, please start seata-server. "
elseecho " init nacos config fail. "
fi

四、运行naocs-config.sh脚本文件

sh nacos-config.sh -h localhost -p 8848 -g SEATA_GROUP  -t cd8c38c5-92ef-49fd-ac8a-3241881665e2 -u nacos -w nacos

参数说明：

-h: host，默认值 localhost

-p: port，默认值 8848

-g: 配置分组，默认值为 'SEATA_GROUP'

-t: 租户信息，对应 Nacos 的命名空间ID字段, 默认值为空 ''

注意！路径中不能出现空格 我这里是错误的，因为配置了环境变量，所以不好修改，所以只能把seata文件复制到其他不带路径的文件下，执行脚本文件，执行完在复制回来。

D:\development utils\seata\seata-server-1.4.2\conf

执行完成后 来到Nacos的配置列表

 bin目录下 双击bat启动seata

五、引入相对应的依赖

对应版本

一、引入依赖以及版本控制

    <parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.6.3</version></parent><properties><java.version>1.8</java.version><spring.boot.version>2.6.8</spring.boot.version><spring-cloud.version>2021.0.1</spring-cloud.version><spring.cloud.alibaba.version>2021.0.1.0</spring.cloud.alibaba.version></properties><dependencies><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-bootstrap</artifactId></dependency><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-loadbalancer</artifactId></dependency><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>1.4.2</version></dependency><dependency><groupId>com.alibaba.nacos</groupId><artifactId>nacos-client</artifactId></dependency></dependencies><dependencyManagement><dependencies><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-dependencies</artifactId><version>${spring-cloud.version}</version><type>pom</type><scope>import</scope></dependency><dependency><groupId>com.alibaba.cloud</groupId><artifactId>spring-cloud-alibaba-dependencies</artifactId><version>${spring.cloud.alibaba.version}</version><type>pom</type><scope>import</scope></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-dependencies</artifactId><version>${spring.boot.version}</version><type>pom</type><scope>import</scope></dependency></dependencies></dependencyManagement>

二、配置bootstrap.yml
