摘要：本文主要介绍了springcloud alibaba + nacos +seata测试分布式事务的AT和XA模式的示例代码，未接入网关，只用了feign之间调用。

简介

项目共分为三个子工程，goods-service、member-service和web-service，在web-service中调用其他两个工程来测试事务。

主要代码和实现步骤

创建父工程`huzhihui-alibaba-seata`，你可以创建你自己工程的名称，pom文件内容如下

        </dependencies>
    </dependencyManagement>

</project>

然后创建三个子工程

goods-service、member-service和web-service

`goods-service`工程主要代码

创建数据库`dynamic_goods`

建表语句

CREATE TABLE `goods` (
  `id` varchar(20) COLLATE utf8mb4_unicode_ci NOT NULL,
  `name` varchar(100) COLLATE utf8mb4_unicode_ci DEFAULT NULL,
  `desc` varchar(200) COLLATE utf8mb4_unicode_ci DEFAULT NULL,
  `create_time` datetime DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci;

如果使用AT模式则需要增加下面的日志表

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=6 DEFAULT CHARSET=utf8;

`bootstrap.yml`

主要配置服务名称和nacos相关配置

spring:
  application:
    name: goods-service
  main:
    allow-bean-definition-overriding: true
  cloud:
    nacos:
      discovery:
        server-addr: 192.168.137.100:8848

主要的代码

GoodsServiceApplication启动类

@MapperScan("com.github.huzhihui.goods.mapper")
@SpringBootApplication
public class GoodsServiceApplication {

    public static void main(String[] args) {
        SpringApplication.run(GoodsServiceApplication.class, args);
    }
}

GoodsEntity实体

@Data
@TableName("goods")
public class GoodsEntity {

    @TableId(type = IdType.INPUT)
    private String id;

    @TableField(value = "`name`")
    private String name;

    @TableField(value = "`desc`")
    private String desc;

    private Date createTime;
}

goodsMapper接口

@Repository
public interface GoodsMapper extends BaseMapper<GoodsEntity> {
}

goodsController控制类入口

@RestController
@RequestMapping(value = "goods")
public class GoodsController {

    @Autowired
    private GoodsMapper goodsMapper;

    @GetMapping(value = "add")
    public String add(String name){
        GoodsEntity goodsEntity = new GoodsEntity();
        goodsEntity.setId(IdWorker.getIdStr());
        goodsEntity.setName(name);
        goodsMapper.insert(goodsEntity);
        return "SUCCESS";
    }

    @GetMapping(value = "update")
    public String update(String id,String name){
        GoodsEntity goodsEntity = new GoodsEntity();
        goodsEntity.setId(id);
        goodsEntity.setName(name);
        goodsMapper.updateById(goodsEntity);
        return "SUCCESS";
    }
}

`member-service`工程主要代码

创建数据库`dynamic_member`

建表语句

CREATE TABLE `user` (
  `id` varchar(20) COLLATE utf8mb4_unicode_ci NOT NULL,
  `name` varchar(40) COLLATE utf8mb4_unicode_ci DEFAULT NULL,
  `address` varchar(100) COLLATE utf8mb4_unicode_ci DEFAULT NULL,
  `create_time` datetime DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci;

如果使用AT模式则需要增加下面的日志表

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`)

@MapperScan("com.github.huzhihui.member.mapper")
@SpringBootApplication
public class MemberServiceApplication {

    public static void main(String[] args) {
        SpringApplication.run(MemberServiceApplication.class, args);
    }

    private String id;

    private String name;

    private String address;

    private Date createTime;
}

UserMapper接口

@Repository
public interface UserMapper extends BaseMapper<UserEntity> {
}

goodsController控制类入口

@RestController
@RequestMapping(value = "user")
public class UserController {

    @Autowired
    private UserMapper userMapper;

    @GetMapping(value = "add")
    public String add(String name){
        UserEntity userEntity = new UserEntity();
        userEntity.setId(IdWorker.getIdStr());

    public String update(String id,String name){
        UserEntity userEntity = new UserEntity();
        userEntity.setId(id);
        userEntity.setName(name);
        userMapper.updateById(userEntity);
        return "SUCCESS";
    }

测试

需要提前在nacos配置一个事务分组，因为上面的配置的分组为hzh_tx_group

`XA`模式

该模式不需要undo这个表，并且事务按照XA协议来，通过分布式事务统一管理，具体可以看官方文档对XA模式的介绍

`AT`模式

该模式需要创建undo表，上面已经列出来了，该模式通过日志补偿方式，可能存在并发情况下补偿失败的情况。

主要代码和实现步骤

创建父工程huzhihui-alibaba-seata，你可以创建你自己工程的名称，pom文件内容如下

然后创建三个子工程

goods-service工程主要代码

创建数据库dynamic_goods

pom.xml

bootstrap.yml

application.yml

主要的代码

member-service工程主要代码

创建数据库dynamic_member
