spring cloud微服务接入seata

一、环境简要说明
二、seata服务端部署

服务端下载
修改conf/registry.conf 配置
初始化seata在nacos中服务端配置
启动seata-server

三、初始化数据库
四、准备spring cloud微服务
五、测试验证

正常下单
异常下单

六、遇到的问题

无法获取seata-server服务注册的信息
获取nacos中的ip地址错误

一、环境简要说明

本文参照seata官方文档示例程序搭建，官网示例地址环境准备
jdk 1.8版本，读者自行准备
mysql 8.0版本，读者自行准备，可参考笔者之前的安装教程
nacos 1.4.3版本，读者自行准备，可参考笔者之前的安装教程

二、seata服务端部署

服务端下载

下载seata1.4.2版本的服务端和源码
下载地址

修改conf/registry.conf 配置

registry {
  # file 、nacos 、eureka、redis、zk、consul、etcd3、sofa
  type = "nacos"

  nacos {
    application = "seata-server"
    serverAddr = "127.0.0.1:8848"
    group = "SEATA_GROUP"
    namespace = ""
    cluster = "default"
    username = "nacos"
    password = "nacos"
  }
}
config {
  # file、nacos 、apollo、zk、consul、etcd3
  type = "nacos"
  nacos {
    serverAddr = "127.0.0.1:8848"
    namespace = ""
    group = "SEATA_GROUP"
    username = "nacos"
    password = "nacos"
    dataId = "seataServer.properties"
  }
}

初始化seata在nacos中服务端配置

参考文档在下载的源码路径seata-1.4.2\script\config-center\README.md
首先将源码目录下的seata-1.4.2\script\config-center\config.txt 和seata-1.4.2\script\config-center\nacos-config.sh 两个文件上传至192.168.220.125虚拟机中
nacos-config.sh文件赋执行权限
执行初始化命令

[root@host125 conf]# pwd
/opt/install/seata-server-1.4.2/conf
[root@host125 conf]# chmod +x nacos-config.sh
[root@host125 conf]# ./nacos-config.sh -h localhost -p 8848 -g SEATA_GROUP -u nacos -w nacos
set nacosAddr=localhost:8848
set group=SEATA_GROUP
cat: /opt/install/seata-server-1.4.2/config.txt: 没有那个文件或目录
=========================================================================
 Complete initialization parameters,  total-count:0 ,  failure-count:0 
=========================================================================
 Init nacos config finished, please start seata-server. 
[root@host125 conf]# mv config.txt ..
[root@host125 conf]# ./nacos-config.sh -h localhost -p 8848 -g SEATA_GROUP -u nacos -w nacos

启动seata-server

[root@host125 bin]# pwd
/opt/install/seata-server-1.4.2/bin
[root@host125 bin]# sh seata-server.sh -p 8091 -h 192.168.220.125

三、初始化数据库

-- 创建 order库、业务表、undo_log表
create database seata_order;
use seata_order;

DROP TABLE IF EXISTS `order_tbl`;
CREATE TABLE `order_tbl` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `user_id` varchar(255) DEFAULT NULL,
  `commodity_code` varchar(255) DEFAULT NULL,
  `count` int(11) DEFAULT 0,
  `money` int(11) DEFAULT 0,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

CREATE TABLE `undo_log`
(
  `id`            BIGINT(20)   NOT NULL AUTO_INCREMENT,
  `branch_id`     BIGINT(20)   NOT NULL,
  `xid`           VARCHAR(100) NOT NULL,
  `context`       VARCHAR(128) NOT NULL,
  `rollback_info` LONGBLOB     NOT NULL,
  `log_status`    INT(11)      NOT NULL,
  `log_created`   DATETIME     NOT NULL,
  `log_modified`  DATETIME     NOT NULL,
  `ext`           VARCHAR(100) DEFAULT NULL,
  PRIMARY KEY (`id`),
  UNIQUE KEY `ux_undo_log` (`xid`, `branch_id`)
) ENGINE = InnoDB
  AUTO_INCREMENT = 1
  DEFAULT CHARSET = utf8;


-- 创建 stock库、业务表、undo_log表
create database seata_stock;
use seata_stock;

DROP TABLE IF EXISTS `stock_tbl`;
CREATE TABLE `stock_tbl` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `commodity_code` varchar(255) DEFAULT NULL,
  `count` int(11) DEFAULT 0,
  PRIMARY KEY (`id`),
  UNIQUE KEY (`commodity_code`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

CREATE TABLE `undo_log`
(
  `id`            BIGINT(20)   NOT NULL AUTO_INCREMENT,
  `branch_id`     BIGINT(20)   NOT NULL,
  `xid`           VARCHAR(100) NOT NULL,
  `context`       VARCHAR(128) NOT NULL,
  `rollback_info` LONGBLOB     NOT NULL,
  `log_status`    INT(11)      NOT NULL,
  `log_created`   DATETIME     NOT NULL,
  `log_modified`  DATETIME     NOT NULL,
  `ext`           VARCHAR(100) DEFAULT NULL,
  PRIMARY KEY (`id`),
  UNIQUE KEY `ux_undo_log` (`xid`, `branch_id`)
) ENGINE = InnoDB
  AUTO_INCREMENT = 1
  DEFAULT CHARSET = utf8;

-- 初始化库存模拟数据
INSERT INTO seata_stock.stock_tbl (id, commodity_code, count) VALUES (1, 'product-1', 9999999);
INSERT INTO seata_stock.stock_tbl (id, commodity_code, count) VALUES (2, 'product-2', 0);

四、准备spring cloud微服务

微服务代码较多，读者可以下载源码自行参考，这里仅展示order服务的主要代码
bootstrap.yml

server:
  port: 9091
spring:
  application:
    name: order-service
  cloud:
    nacos:
      config:
        server-addr: 192.168.220.125:8848
        file-extension: yml
      discovery:
        # Nacos 注册中心地址
        server-addr: 192.168.220.125:8848
    # seata 服务分组，要与服务端nacos-config.txt中service.vgroup_mapping的后缀对应
    alibaba:
      seata:
        tx-service-group: my_test_tx_group
  # 数据源配置
  datasource:
    url: jdbc:mysql://192.168.220.125:3306/seata_order?serverTimezone=UTC&useUnicode=true&characterEncoding=utf-8&allowMultiQueries=true
    driverClassName: com.mysql.cj.jdbc.Driver
    username: root
    password: xxxxx
seata:
  registry: # TC服务注册中心的配置，微服务根据这些信息去注册中心获取tc服务地址
    # 参考tc服务自己的registry.conf中的配置
    type: nacos
    nacos: # tc
      server-addr: 192.168.220.125:8848
      namespace: ""
      group: SEATA_GROUP
      application: seata-server # tc服务在nacos中的服务名称
  tx-service-group: my_test_tx_group # 事务组，根据这个获取tc服务的cluster名称

logging:
  level:
    io:
      seata: debug

    @GlobalTransactional
    @Transactional(rollbackFor = Exception.class)
    public void placeOrder(String userId, String commodityCode, Integer count) {
        BigDecimal orderMoney = new BigDecimal(count).multiply(new BigDecimal(5));
        Order order = new Order();
        order.setUserId(userId);
        order.setCommodityCode(commodityCode);

        order.setMoney(orderMoney);
        orderDAO.insert(order);
        stockFeignClient.deduct(commodityCode, count);

    }

六、遇到的问题

无法获取seata-server服务注册的信息

ERROR 8136 — [imeoutChecker_1] i.s.c.r.netty.NettyClientChannelManager : no available server to connect.

原因分析：seata-all 0.7.1版本getNamingInstance().getAllInstances(PRO_SERVER_ADDR_KEY, clusters)无法指定group，导致使用默认的group获取nacos中实例，而我的seata-server服务是部署在SEATA-GROUP中的

springCloud 集成pay springcloud集成seata_spring_06

解决：seata-all 1.3.0版本之后才支持nacos的group配置，因此版本必须大于1.3.0才可以，笔者升级版本到1.4.2后解决

[#2620] support group configuration in Nacos registry

获取nacos中的ip地址错误

 at io.seata.spring.annotation.datasource.DataSourceProxyHolder.putDataSource(DataSourceProxyHolder.java:88) [seata-all-1.4.2.jar:1.4.2]

我的seata-server是部署在虚拟机中的，不能通过127.0.0.1访问，如果是通过nacos获取的ip应该是192.168.220.125才对

原因分析：跟踪调试后发现seata-all 1.4.2版本registryTypeName获取的是file类型，并不是registry.conf文件中配置的nacos，具体原因未知，也懒得去分析了，直接配置文件中指定registry.type=nacos

springCloud 集成pay springcloud集成seata_java_07

解决：在微服务配置文件中指定registry.type=nacos

seata:
  registry: # TC服务注册中心的配置，微服务根据这些信息去注册中心获取tc服务地址
    # 参考tc服务自己的registry.conf中的配置
    type: nacos
    nacos: # tc
      server-addr: 192.168.220.125:8848
      namespace: ""
      group: SEATA_GROUP
      application: seata-server # tc服务在nacos中的服务名称
  tx-service-group: my_test_tx_group # 事务组，根据这个获取tc服务的cluster名称
