环境准备
2.1 下载nacos并安装启动
nacos下载：https://github.com/alibaba/nacos/releases/tag/1.2.0
这里自行安装nacos,Nacos 快速入门：Quick Start for Nacos
在浏览器打开Nacos web 控制台：http://ip:8848/nacos/index.html
2.2 下载seata server 并安装启动
2.2.1 在 Seata Release 下载最新版的 Seata Server 并解压得到如下目录：
. ├──bin ├──conf ├──file_store └──lib
2.2.2 修改 conf/registry.conf 配置，
目前seata支持如下的file、nacos 、apollo、zk、consul的注册中心和配置中心。这里我们以nacos 为例。 将 type 改为 nacos
registry {
# file nacos
type = "nacos"
nacos {
serverAddr = "192.168.10.200:8848"
namespace = ""
cluster = "default"
}
file {
name = "file.conf"
}
}
config {
# file、nacos 、apollo、zk、consul
type = "nacos"
nacos {
serverAddr = "192.168.10.200:8848"
namespace = ""
}
file {
name = "file.conf"
}
}
- serverAddr = "192.168.10.200:8848" ：nacos 的地址
- namespace = "" ：nacos的命名空间默认为``
- cluster = "default" ：集群设置未默认
default
注意： seata0.9.0之后，配置如下, 其中namespace = ""
2.2.3 启动 Seata Server
使用db 模式启动
cd .. sh ./bin/seata-server.sh
3 使用seata-spring-boot-starter案例分析
seata-spring-boot-starter是使用springboot自动装配来简化seata-all的复杂配置。1.0.0可用于替换seata-all，GlobalTransactionScanner 自动初始化（依赖SpringUtils）若其他途径实现GlobalTransactionScanner初始化，请保证io.seata.spring.boot.autoconfigure.util.SpringUtils先初始化； seata-spring-boot-starter默认开启数据源自动代理，用户若再手动配置DataSourceProxy将会导致异常。

参考官网中用户购买商品的业务逻辑。也可以自己创建项目，引入依赖，配置数据源，使用注解@GlobalTransactional就可以测试，官方整个业务逻辑由4个微服务提供支持：
- 库存服务：扣除给定商品的存储数量。
- 订单服务：根据购买请求创建订单。
- 帐户服务：借记用户帐户的余额。
- 业务服务：处理业务逻辑。
请求逻辑架构
3.1 github地址
springboot-dubbo-seata：https://github.com/lidong1665/spring-cloud-learning-example/tree/master/springboot-dubbo-seata-nacos
-
samples-common ：公共模块
-
samples-account ：用户账号模块
-
samples-order ：订单模块
-
samples-stock ：库存模块
-
samples-business ：业务模块
3.2 账户服务：AccountDubboService
/**
* @Author: lidong
* @Description 账户服务接口
* @Date Created in 2019/9/5 16:37
*/
public interface AccountDubboService {
/**
* 从账户扣钱
*/
ObjectResponse decreaseAccount(AccountDTO accountDTO);
}
3.3 订单服务：OrderDubboService
/**
* @Author: lidong
* @Description 订单服务接口
* @Date Created in 2019/9/5 16:28
*/
public interface OrderDubboService {
/**
* 创建订单
*/
ObjectResponse<OrderDTO> createOrder(OrderDTO orderDTO);
}
3.4 库存服务：StockDubboService
/**
* @Author: lidong
* @Description 库存服务
* @Date Created in 2019/9/5 16:22
*/
public interface StockDubboService {
/**
* 扣减库存
*/
ObjectResponse decreaseStock(CommodityDTO commodityDTO);
}
3.5 业务服务：BusinessService
/**
* @Author: lidong
* @Description
* @Date Created in 2019/9/5 17:17
*/
public interface BusinessService {
/**
* 出处理业务服务
* @param businessDTO
* @return
*/
ObjectResponse handleBusiness(BusinessDTO businessDTO);
}
业务逻辑的具体实现主要体现在 订单服务的实现和业务服务的实现
订单服务的实现
@Service
public class TOrderServiceImpl extends ServiceImpl<TOrderMapper, TOrder> implements ITOrderService {
@Reference(version = "1.0.0")
private AccountDubboService accountDubboService;
/**
* 创建订单
* @Param: OrderDTO 订单对象
* @Return: OrderDTO 订单对象
*/
@Override
public ObjectResponse<OrderDTO> createOrder(OrderDTO orderDTO) {
ObjectResponse<OrderDTO> response = new ObjectResponse<>();
//扣减用户账户
AccountDTO accountDTO = new AccountDTO();
accountDTO.setUserId(orderDTO.getUserId());
accountDTO.setAmount(orderDTO.getOrderAmount());
ObjectResponse objectResponse = accountDubboService.decreaseAccount(accountDTO);
//生成订单号
orderDTO.setOrderNo(UUID.randomUUID().toString().replace("-",""));
//生成订单
TOrder tOrder = new TOrder();
BeanUtils.copyProperties(orderDTO,tOrder);
tOrder.setCount(orderDTO.getOrderCount());
tOrder.setAmount(orderDTO.getOrderAmount().doubleValue());
try {
baseMapper.createOrder(tOrder);
} catch (Exception e) {
response.setStatus(RspStatusEnum.FAIL.getCode());
response.setMessage(RspStatusEnum.FAIL.getMessage());
return response;
}
if (objectResponse.getStatus() != 200) {
response.setStatus(RspStatusEnum.FAIL.getCode());
response.setMessage(RspStatusEnum.FAIL.getMessage());
return response;
}
response.setStatus(RspStatusEnum.SUCCESS.getCode());
response.setMessage(RspStatusEnum.SUCCESS.getMessage());
return response;
}
}
整个业务的实现逻辑
@Service
@Slf4j
public class BusinessServiceImpl implements BusinessService{
@Reference(version = "1.0.0")
private StockDubboService stockDubboService;
@Reference(version = "1.0.0")
private OrderDubboService orderDubboService;
private boolean flag;
/**
* 处理业务逻辑
* @Param:
* @Return:
*/
@GlobalTransactional(timeoutMills = 300000, name = "dubbo-gts-seata-example")
@Override
public ObjectResponse handleBusiness(BusinessDTO businessDTO) {
log.info("开始全局事务，XID = " + RootContext.getXID());
ObjectResponse<Object> objectResponse = new ObjectResponse<>();
//1、扣减库存
CommodityDTO commodityDTO = new CommodityDTO();
commodityDTO.setCommodityCode(businessDTO.getCommodityCode());
commodityDTO.setCount(businessDTO.getCount());
ObjectResponse stockResponse = stockDubboService.decreaseStock(commodityDTO);
//2、创建订单
OrderDTO orderDTO = new OrderDTO();
orderDTO.setUserId(businessDTO.getUserId());
orderDTO.setCommodityCode(businessDTO.getCommodityCode());
orderDTO.setOrderCount(businessDTO.getCount());
orderDTO.setOrderAmount(businessDTO.getAmount());
ObjectResponse<OrderDTO> response = orderDubboService.createOrder(orderDTO);
//打开注释测试事务发生异常后，全局回滚功能
// if (!flag) {
// throw new RuntimeException("测试抛异常后，分布式事务回滚！");
// }
if (stockResponse.getStatus() != 200 || response.getStatus() != 200) {
throw new DefaultException(RspStatusEnum.FAIL);
}
objectResponse.setStatus(RspStatusEnum.SUCCESS.getCode());
objectResponse.setMessage(RspStatusEnum.SUCCESS.getMessage());
objectResponse.setData(response.getData());
return objectResponse;
}
}
3.6 使用seata的分布式事务解决方案处理dubbo的分布式事务
我们只需要在业务处理的方法handleBusiness添加一个注解 @GlobalTransactional
@GlobalTransactional(timeoutMills = 300000, name = "dubbo-gts-seata-example")
@Override
public ObjectResponse handleBusiness(BusinessDTO businessDTO) {
}
timeoutMills: 超时时间name：事务名称
3.7 准备数据库
注意: MySQL必须使用InnoDB engine.
创建数据库 并导入数据库脚本
DROP DATABASE IF EXISTS seata;
CREATE DATABASE seata;
USE seata;
DROP TABLE IF EXISTS `t_account`;
CREATE TABLE `t_account` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`user_id` varchar(255) DEFAULT NULL,
`amount` double(14,2) DEFAULT '0.00',
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8;
--
----------------------
-- Records of t_account
-- ----------------------------
INSERT INTO `t_account` VALUES ('1', '1', '4000.00');
-- ----------------------------
-- Table structure for t_order
-- ----------------------------
DROP TABLE IF EXISTS `t_order`;
CREATE TABLE `t_order` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`order_no` varchar(255) DEFAULT NULL,
`user_id` varchar(255) DEFAULT NULL,
`commodity_code` varchar(255) DEFAULT NULL,
`count` int(11) DEFAULT '0',
`amount` double(14,2) DEFAULT '0.00',
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=64 DEFAULT CHARSET=utf8;
-- ----------------------------
-- Records of t_order
-- ----------------------------
-- ----------------------------
-- Table structure for t_stock
-- ----------------------------
DROP TABLE IF EXISTS `t_stock`;
CREATE TABLE `t_stock` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`commodity_code` varchar(255) DEFAULT NULL,
`name` varchar(255) DEFAULT NULL,
`count` int(11) DEFAULT '0',
PRIMARY KEY (`id`),
UNIQUE KEY `commodity_code` (`commodity_code`)
) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8;
-- ----------------------------
-- Records of t_stock
-- ----------------------------
INSERT INTO `t_stock` VALUES ('1', 'C201901140001', '水杯', '1000');
-- ----------------------------
-- Table structure for undo_log
-- 注意此处0.3.0+ 增加唯一索引 ux_undo_log
-- ----------------------------
DROP TABLE IF EXISTS `undo_log`;
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;
-- ----------------------------
-- Records of undo_log
-- ----------------------------
SET FOREIGN_KEY_CHECKS=1;
会看到如上的4个表
+-------------------------+ | Tables_in_seata | +-------------------------+ | t_account | | t_order | | t_stock | | undo_log | +-------------------------+
这里为了简化我将这个三张表创建到一个库中,使用是三个数据源来实现。

3.8.4 AccountExampleApplication 启动类的配置
package io.seata.samples.integration.account;
import org.apache.dubbo.config.spring.context.annotation.EnableDubbo;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;

@SpringBootApplication(scanBasePackages = "io.seata.samples.integration.account")
@MapperScan({"io.seata.samples.integration.account.mapper"})
@EnableDubbo(scanBasePackages = "io.seata.samples.integration.account")
public class AccountExampleApplication {
public static void main(String[] args) {
SpringApplication.run(AccountExampleApplication.class, args);
}
}
-
@EnableDubbo等同于@DubboComponentScan和@EnableDubboConfig组合 -
@DubboComponentScan扫描 classpaths 下类中添加了@Service和@Reference将自动注入到spring beans中。 -
@EnableDubboConfig 扫描的dubbo的外部化配置。
4 启动所有的sample模块
启动 samples-account、samples-order、samples-stock、samples-business
并且在nocos的控制台查看注册情况: http://192.168.10.200:8848/nacos/#/serviceManagement
我们可以看到上面的服务都已经注册成功。
5 测试
5. 1 发送一个下单请求
使用postman 发送 ：http://localhost:8104/business/dubbo/buy
参数：
{
"userId":"1",
"commodityCode":"C201901140001",
"name":"fan",
"count":50,
"amount":"100"
}
返回
{
"status": 200,
"message": "成功",
"data": null
}
这时候控制台：
2020-01-08 10:49:37.693 INFO 24032 --- [nio-8104-exec-2] i.s.s.i.c.controller.BusinessController : 请求参数：BusinessDTO(userId=1, commodityCode=C201901140001, name=fan, count=50, amount=100)

事务提交成功，
我们来看一下数据库数据变化
t_account
t_order
t_stock
数据没有问题。
5.2 测试回滚
我们samples-business将BusinessServiceImpl的handleBusiness2 下面的代码去掉注释
if (!flag) {

1. 添加依赖
添加Spring Cloud Alibaba 依赖管理工具和 Seata 依赖
Gradle
Maven
需要注意的是Spring Cloud Alibaba 的毕业版本的 GroupId 是 com.alibaba.cloud
spring-cloud-starter-alibaba-seata这个依赖中只依赖了spring-cloud-alibaba-seata，所以在项目中添加spring-cloud-starter-alibaba-seata 和spring-cloud-alibaba-seata是一样的
2. 添加Seata 配置文件
registry.conf
该配置用于指定 TC 的注册中心和配置文件，默认都是 file; 如果使用其他的注册中心，要求 Seata-Server 也注册到该配置中心上
registry.conf
file.conf
该配置用于指定TC的相关属性；如果使用注册中心也可以将配置添加到配置中心
file.conf
需要注意的是 service.vgroup_mapping这个配置，在 Spring Cloud 中默认是${spring.application.name}-fescar-service-group ，可以通过指定application.properties的 spring.cloud.alibaba.seata.tx-service-group这个属性覆盖，但是必须要和 file.conf 中的一致，否则会提示 no available server to connect
3. 注入数据源
Seata 通过代理数据源的方式实现分支事务；MyBatis 和 JPA 都需要注入 io.seata.rm.datasource.DataSourceProxy, 不同的是，MyBatis 还需要额外注入 org.apache.ibatis.session.SqlSessionFactory
MyBatis
JPA
如果使用的是 Hikari 数据源，需要修改数据源的配置，以及注入的 Bean 的配置前缀
spring.datasource.hikari.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.hikari.jdbc-url=jdbc:mysql://localhost:3306/seata?useUnicode=true&characterEncoding=utf8&allowMultiQueries=true&useSSL=false
spring.datasource.hikari.username=root
spring.datasource.hikari.password=123456
@Bean
@ConfigurationProperties(prefix = "spring.datasource.hikari")
public DataSource dataSource() {
return new HikariDataSource();
}
4. 添加 undo_log 表
在业务相关的数据库中添加 undo_log 表，用于保存需要回滚的数据
CREATE TABLE `undo_log`
(
`id` BIGINT(20) NOT NULL AUTO_INCREMENT,
`branch_id` BIGINT(20) NOT NULL,
