1.4.2 Seata以nacos作为注册中心的配置和使用
下载Seata 1.4.2
1. 解压Seata 1.4.2
2. Seata目录如下
3. 下载Seata Source Code
4. 解压后找到Script目录
这个目录下的内容在配置Seata的时候需要用到
配置seata
1. 创建相关数据库和表
默认情况下, seata的存储方式是文件, 我们改为以数据库的方式存储, 这里可以不改, 看需求
建表语句
建表语句 Seata Source Code的Script目录下的server / db 里
以mysql为例
-- -------------------------------- 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(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;
我在名为seata的数据库建立了表
2. 修改file.conf文件
进入seata目录, 进入config目录
注意: 进入的是seata的目录, 不是Source Code
3. 修改registry.conf文件
跟file.conf在同一个目录下
修改 type = “nacos”
还是这个文件找到最下面, 修改config
- 这里namespace没有配置, 默认情况下就在public下, 如果想改, 可以自己修改, 我以最简单的方式配置
4. 把配置上传到nacos
打开Seata Source Code文件夹, 找到config-center, 进入, 打开context.txt
在context.txt文件中修改seata配置
其他不用修改, 留意一下这个
把context.txt文件中的内容上传到nacos
提前启动nacos
进入nacos目录
不双击打开
打开git bash
sh nacos-config.sh -h 127.0.0.1 -p 8848 -u nacos -w nacos
-h 是 host, 是你的nacos的ip地址, 本地就用 127.0.0.1
-p 是nacos的端口号 8848
-u 是 username 即用户名 默认都是nacos
-w 是 password 即密码 默认也是nacos
运行
运行完成
到这里就完成了配置上传nacos
Windows启动seata
默认情况下
用jdk1.8直接可以启动seata
其他版本的博主没有试过
- 进入bin目录
- 双击.bat文件即可
1. jdk8启动
直接双击.bat文件即可
启动成功
2. jdk17启动
- 编辑.bat文件, 用记事本打开
- 修改 %JAVACMD%
将原来的替换为
%JAVACMD% %JAVA_OPTS% -server --add-opens=java.base/java.lang=ALL-UNNAMED -Xmx2048m -Xms2048m -Xmn1024m -Xss512k -XX:SurvivorRatio=10 -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=256m -XX:MaxDirectMemorySize=1024m -XX:-OmitStackTraceInFastThrow -XX:-UseAdaptiveSizePolicy -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath="%BASEDIR%"/logs/java_heapdump.hprof -XX:+DisableExplicitGC -Xlog:gc:"%BASEDIR%"/logs/seata_gc.log -verbose:gc -Dio.netty.leakDetectionLevel=advanced -Dlogback.color.disable-for-bat=true -classpath %CLASSPATH% -Dapp.name="seata-server" -Dapp.repo="%REPO%" -Dapp.home="%BASEDIR%" -Dbasedir="%BASEDIR%" io.seata.server.Server %CMD_LINE_ARGS%
- 双击启动
3. 闪退问题
如果出现闪退, 可能是jdk版本不对, 检查一下jdk版本, jdk17启动要改配置
4. 其他配置
见下面的测试
Linux启动seata
linux不能使用jdk17启动, 使用jkd8一定是可以的, 不需要任何修改, 直接启动即可
如果使用高版本jdk, 会出下面问题
测试seata
- 订单服务
- 库存服务
- 订单服务通过open-feign调用库存服务
- 在订单服务抛出异常, 检查能不能进行回滚操作

3. 配置
(1). application.properties配置
在每一个服务中, 对配置seata所需要的信息
订单服务的配置
server.port=8002
spring.application.name=order-two
spring.cloud.nacos.discovery.server-addr=localhost:8848
spring.cloud.nacos.discovery.namespace=public
spring.cloud.nacos.discovery.service=${spring.application.name}
spring.cloud.nacos.discovery.group=DEFAULT_GROUP
spring.jpa.hibernate.ddl-auto=update
spring.datasource.url=jdbc:mysql://localhost:3306/seata_order?useUnicode=true&characterEncoding=utf8
spring.datasource.username=root
spring.datasource.password=123456
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.jpa.show-sql=true
spring.jpa.open-in-view=false
seata.registry.type=nacos
seata.registry.nacos.server-addr=localhost:8848
seata.registry.nacos.username=nacos
seata.registry.nacos.password=nacos
seata.config.type=nacos
seata.config.nacos.server-addr=localhost:8848
seata.config.nacos.password=nacos
seata.config.nacos.username=nacos
# 这里的 my_test_tx_group 在下面说一下
seata.tx-service-group=my_test_tx_group
seata.service.vgroup-mapping.my_test_tx_group=default
库存服务配置
server.port=8004
spring.application.name=stock-two
spring.cloud.nacos.discovery.server-addr=localhost:8848
spring.cloud.nacos.discovery.namespace=public
spring.cloud.nacos.discovery.service=${spring.application.name}
spring.cloud.nacos.discovery.group=DEFAULT_GROUP
spring.jpa.hibernate.ddl-auto=update
spring.datasource.url=jdbc:mysql://localhost:3306/seata_storage?useUnicode=true&characterEncoding=utf8
spring.datasource.username=root
spring.datasource.password=123456
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.jpa.show-sql=true
seata.registry.type=nacos
seata.registry.nacos.server-addr=localhost:8848
seata.registry.nacos.username=nacos
seata.registry.nacos.password=nacos
seata.config.type=nacos
seata.config.nacos.server-addr=localhost:8848
seata.config.nacos.password=nacos
seata.config.nacos.username=nacos
seata.tx-service-group=my_test_tx_group
seata.service.vgroup-mapping.my_test_tx_group=default
# nacos注册配置
seata.registry.type=nacos
seata.registry.nacos.server-addr=localhost:8848
seata.registry.nacos.username=nacos
seata.registry.nacos.password=nacos
# 让nacos发现刚才上传那些配置文件
seata.config.type=nacos
seata.config.nacos.server-addr=localhost:8848
seata.config.nacos.password=nacos
seata.config.nacos.username=nacos
my_test_tx_group要一致
seata.tx-service-group=my_test_tx_group
seata.service.vgroup-mapping.my_test_tx_group=default
(2). 添加注解@EnableAutoDataSourceProxy
在两个服务的启动类似添加@EnableAutoDataSourceProxy注解
(3). 添加启动参数
-
打开启动配置
-
添加参数
--add-opens=java.base/java.lang.reflect=ALL-UNNAMED --add-opens=java.base/java.lang=ALL-UNNAMED
(4). 增加undo_log表
在订单服务和库存服务数据库中增加undo_log表
-- for AT mode you must to init this sql for you business database. the seata server not need it.
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 = utf8 COMMENT ='AT transaction mode undo table';
(5). 主要逻辑
- controller中
- save方法
- 库存服务controller
- 扣减库存方法
- 数据库中的信息
第一张图是订单表, 第二张图是库存表
下订单后会扣减10
(5). 启动项目
项目启动之前, 确保seata启动成功
当项目启动成功后, seata也会出现注册成功
清空控制台的记录, 调用服务观察情况
订单服务情况
